Title: MANTA TWIN TRACK UPDATE 2/18
Post by: Raiderfan on May 15, 2011, 08:37:29 AM
  I figured you guy's might be interested in the guts of one of these things. The chassis is in great shape, suspensions, tracks etc. The motor is a 77'Z 440. which the guy brought out and Bob Bracey installed for him. Bob bought all the chassis in 75'. This was put together in Nov 76'. What do you call it? This has twin CAT chain cases. He did 3 or 4 like this. The glass is pretty rough, but complete. It was stored in an old trailer that the roof had collapsed.
  I'm breaking the cardinal rule and working on 2 restorations at once. The glass and motor are the big things. The rest disassembled and cleaned. And paint/ powder coat the few metal parts.
  Not looking for the over restored,polished look. I'm definitely riding this bad boy! I need to work on a quick connect for the butterfly steering wheel. At 6', in jeans and sneakers I can barely get in.
  Now if this sled was built in Nov of 76', Did the guy buy a 77' Z crate motor? The owners name was Dick Dawson.

Well, one long day and it's pretty much all apart. The spindles are stuck in the front end and the secondary is stuck on the shaft.

Motor out, had to sawzall off the motor mounts. Motor plate is shot.

Ever seen a Hurst Airheart Hydro brake assembly? complete with Titanium cleat brake pedal bracket.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010031-1.jpg)
2 seperate shafts connect the 2 CAT chain cases with a splice sleeve.

I lOVE stuck bearing and collars!! This is but a sample of them.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010059-1.jpg)
With the secondary stuck on the shaft, I had to do a little thinking to get the right side apart. Took all this out as one piece.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010062-1.jpg)
Suprise! another one had to be cut off!
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010065-1.jpg)
Just have to figure out how to get those frozen spindles out!

I've got a buddy with a steam jenny, I'm going to give it a shot at cleaning the chassis up. Also need to find a pile of RA100NPPB bearings with the collars.

Very cool! Lookin good! Compared to a lot of texas chassis' that I thought this sled was probably based or "related" to it is very simple looking. Was there any kind of differential system in the drive line like the ski doo twin tracks and Gille's allouette had?

hey Mark the gears look close to what you buy at Mills Fleet Farm (in the farm section) including the chain. As for getting your spindles out use some penetrating oil then find some thing that is the same size of the spindle then lightly tap them out, if this doesn't work take a Lp torch with a wide angle head & heat the outside of it then by tapping on the spindle shafts you should be able to get them out, if you are afraid of wrecking the top of the steel shafts use a center punch in the center of the spindle.

Lynxer, Nope. Both drive shaft go to the lower sprocket of the chain cases. The upper gears run right to the secondary shaft(s)

Greg, The front ends are all enclosed. No way to get heat to the spindle "sleeve". I have some pentrating oil on them now. I don't want to drill out the rivets holding those front end assemblies on. But if I have to, I will. I think tomorrow I'll pull all the ski assemblies off I can. I might be able to put a small whistle pipe wrench on the spindle and break it loose.
  Thanks for the heads up on the chain and gears. One chain is junk. water in the chain case. These just had tranny fluid in them. I think I'm going with either gear oil or grease.

Always feels great to overcome an obstacle like that in a the course of a restoration, Mark. Ingenuity and keeping at it made it happen. It seems like it turned out to be kind of a belated B'day present...

  You know, I got a couple of restorations under my belt. Always wondered how my hours I actually had into them. I guess I never cared enough to figure it out. This one I have decided to keep track. Now being lazy, compound that with disorganized this could be a real challenge.
 I'm going to get the clip board out with some lined paper and put it right by the sled hanging on a nail. Close, convenient, how can I go wrong?
  One thing I quickly learned is this is a BIG chassis, I'm guessing equivalent to two regular ones. Cleaning is endless. Hey Lynxer, Want to come over?

I kept track of hours last week. From Monday to Sunday I have 68 hours into the sno pro. Every day I have came home filthy. Ms. Lynxer has lectured to my how gross my shower is this week and how she has cleaned it twice.  h,,,it Cleaning Cleaning Cleaning every single part, nut and bolt. It is alright though. Worth it in the end

I think I am "busy" sorry man ha  blondieb You will have fun.

Invest in some wire and brass wire brushes! Lots of carb cleaner Lots of purple power Degreaser and LOTS of Scuff pads!

Yes, endless hours of degreasing, cleaning, derusting, painting. I really don't want to know how many hours I have in the Suzuki project! It will be too many, regardless. This is my first full restoration, the first two were just fix-ups.

I use a lot of the spray brake cleaner for degreasing, Haven't had it wreck any rubber parts or paint yet.
Title: Re: MANTA TWIN TRACK UPDATE 5/28
Post by: Raiderfan on May 28, 2011, 11:11:54 AM
Got the chassis all cleaned up. A mere 20 hours. Some of the aluminum is pretty bad G%%R. Simple Green and a scrub brush, aluminum mag cleaner, some portions a random orbit palm sander with 150 grit, 220 wet sand, 320,400,600, and finally polishing compound. There is still a lot of pitting but it is what it is. I might tighten it up with a little Mothers.
  This is like the picture of the hot chick blondieb. Pictures are A LOT better than the real thing testui.

The worst pitting is from the seat forward. I don't like it but what are my options? I'm not cutting and replacing pieces.

I think that pitting could lead to problems later on. Now would be the time to fix the panels that are the worst. The pitting/corrosion has taken some of the strength away from the aluminum now. You're going through all this trouble to make it a rider again,I would fix what needs to be fixed & be done with it. good luck. Just my .03 cents. whistle

Post by: Raiderfan on May 29, 2011, 04:51:39 PM
Structurally it's not an issue. More cosmetic. The damaged area in question is the main chassis pan piece. front to back, bottom, up the sides with a ear at the top.
The piece that looks like a tie rod cover is pitted on the front half. I can replace that at any point easily. In the future. I'm an expert at aircraft rivets now 2utp.

Post by: Nutter on May 30, 2011, 10:10:55 AM
I'd make new stuff for a resto of this magnitude. It appears to be just flat with bends, no forming or stamping. It's a perfect candidate for replacement panel.
Title: Re: MANTA TWIN TRACK UPDATE 5/28
Post by: lynxer on May 31, 2011, 01:07:22 PM
See to me I don't like replacing pieces like that. It might not exactly be "Patina" but it is original. I am a firm believer in Original parts even if they are a little pitted or dented. Replacement parts just aren't the same and I can pick them out pretty good on just about any restored sled. You aren't going to exactly see the pieces you are thinking about replacing, but that is all the more reason just to leave them the way they are and keep it as original as possible.

Got a little shop time in this week 2utp. One suspension down, one to go. The usual frozen shafts, bolts that would not come out bs. Hyfax are like new m0vs. Everything either greased or anti-siezed during reassembly. I installed a few extra washers as the nut/bolt were wearing on the suspension half.

A little more progress on the sled. I figured I'd give cleaning the brake rotor a shot. I sand blasted it and then hit it with my palm sander 100 then 150 grit.

(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010101.jpg)

Working on getting the suspensions back in. Missing some lock washers for the other side so that will have to wait. Why is it that you take a ton of pictures EXCEPT the stuff you really need. I took that chain case off 4 times! Putting this together upside down is a lot easier as far as the drive shaft, track and suspension. But crawling under for the chain case is getting old.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010102.jpg)

This sled got hit in the back end at some point. I straightened out the back end, but I'm thinking the chassis was flared out in the back for the rear axle nut.

LOL Raiderfan back in the day a supervisor said you must start out as a grinder then work your way up to a welder, what you learn is how to grind easier, smarter & to hide mistakes, then welding would be easy. On your grinding with aluminum put a little brown roush on the sanding pad, what it does is cuts better. You can use the same process on buffing aluminum. The brown roush (tripolio) has grit in it and works.
The sled is looking pretty good so far, the engine though a little tough, but should clean up nicely with a little TLC, thanks for posting pics of your project

You'll see new hardware. I'm tired of rusted nut's and bolts. If you blast them the plating is gone. Nothing special about the hardware on this one. They just used off the shelf or what was on hand. I'm sure none had grade 8 bolts with the plating but this one does now.

 Well, to be honest it's been too hot to work in the garage. I got a little farther this last week.
 Necessity being the mother of invention, I had to make a spring compressor.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010113-1.jpg)
These springs are like truck springs! Safety first! I felt a little better with the Quick Grips on there.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010112-1.jpg)
The brake line in ran and the brakes are bleed. As with just about everything I do, 3rd time the charm. I had to make a tech call to Hurst Airheart. Who knew there was a .015" hole in there? I mean really .015" for the brake fluid to pass through. How about that cleat for an extension. New gas and brake pedals are on.

Steering is all back together.

Just working on the last Cobra. The shock was shot. None to be had. Over a few beer's with the welder friend we devised a plan to swap over the spring adjustment collar from one of the rear shock and I'll buy two new aftermarket ones for the back.
  Got the motor dropped off at KKWILL's place yesterday. 2utp

9 phone calls later, I found some 1/8" grey lexan. I wish people would have the common courtesy to at least call back.

4 hours into the windshield. Not counting the two paper mock ups.

Now I can move on the body.

The seat cover continues to have me scratching my head. The seat bucket is cut to allow the driver a little more room, sitting lower and the floor pan is cut for the same reason. I just can't make up my mind on the foam thickness for the seat bottom.

Awesome project Mark!  I can't wait to see this one in person!  This is the first I've checked out this thread.  You really need to share what's going on in your life with your friends!  LOL!!

Just a thought on your seat upholstery - Have you searched any of the vintage kart sites?  There are people making repro seats for the old karts, maybe they can help you out.

Any chance you'll have it ready for the Coudersport vintage weekend?

Brett, I have checked out the vinage kart sites as well as the vintage dragster sites. The Kart seats are a little different. I never got around to asking where they got the seat buckets from.
  Trying my best to get it done. When is the Coudersport weekend?


The seats done!

The body is DONE!! The guy did a great job. He ended up sanding just about all the gel coat off.
I have to get off my ass and get this done. I have a long list of stuff yet to do. Next is getting the pin stripes painted on. The motor should be done this week!

Progress is slow here. Last night's partying isn't helping. The motor is back. It needed new crank bearings,(1) rod, pistons/rings. I did the recoil. I got the new motor plate all drilled and the motor mounted to it.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010226-1.jpg)
I got the snow flaps installed, who would think it would take 3 tries? The flaps are not mounts solid to the chassis, They hang loose on the bolt. So I just double nutted.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010222-1.jpg)
This thing came apart hard. Some is not going back together very easy. I have no idea how they put the left side chain case together.  ??hed? You need to get all the parts on the shaft first. There is no room to get in to put the chain on or tighten the collar and set screw on the gear.
  I'm going to call a tool maker friend tomorrow and see if he will machine that slot a few more inches so I can slide that secondary over more to give me a little more room.

Paul, I'm trying to get it done for the Whiteout 2/11-12.   P3n 150 plus hours and counting

Working on cleaning up the primary,I'm thinking of leaving the "tin can" off. It's pretty rusty. I need some buttons too.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010227-1.jpg)

Mocked up a bumper, I'm thinking 1/4" or 3/8" aluminum. I think I like it. I'd like to see if I can get the MANTA milled into the face of it. Way better than the barn door handles that were on it.

Captain's log star date 1/30. We're running low on beer. I fear a mutiny.
 Just a weekend of one step forward and 2 back. Speaking of back's, mines killing me from putting that motor in and taking it back out.

The belt I ordered is wrong. Too short and Too narrow. Nice job D.A 2utp I ordered the replacement no. from the one that was on there. ??hed?
 I did not want to take that primary apart again. That clutch is set up for a 1 1/4" belt. the one I ordered was 1 3/16"  doh
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010239-2.jpg)
Now in order to change the belt you have to loosen the 4 set screws and ever so gingerly dead horse massage that coupler past the space between the 2 shafts and slide the belt on.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010229-4.jpg)
Now, you know when you take something apart and you know your going to remember that one thing? When I made the new motor plate I did not want to trim it until the clutch was on.The damn primary is only .050 away from the motor plate. doh S.O.B I knew that too. Motor back out and the motor plate had to come off again.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010240-1.jpg)
Creative drilling sawzall and filing and we have the problem solved. kis,,,s ass Hurdled another mouse turd.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010241-1.jpg)
Down the road to NY Rebel sled salvage. 6 belts later I have one that's close. Not perfect but close.
Motor back in again 2utp Doing a little fitting of the plumbing as well.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010248.jpg)

Fuel pumps mounted in their original spots.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010249.jpg)

Went to pick up the body today from the pin striper. 2utp It turned out great. Had a hell of a time finding someone to do hand painted pin stripe.

We talked about a "In Memory" type thing on the sled. We kicked a few idea's around. I did not know Dick so the "In Memory" thing just didn't seem to fit. We decided on just his name. Actually in a different spot. Up by the "flame" was where we had agreed upon. I really like it better where he put it. Now that I see it.
(http://i245.photobucket.com/albums/gg54/raiderfan73/P1010247.jpg)

Next is to get the body off that frame, flip it upside down on the horses to install new foam. Yeah, like I won't F this up. I'm sure nothing could possibly happen to the body during all this.  R%%

Your the second person that has asked. I thought Texas Products or Bob made them. It's just a push pull auto switch. That piece of Delron sp? is just part of the full tether for the single. I have a friend with a Texas Products part catalog. I have to ask him if it's in there.

Another day in the mine. I would get more accomplished if I were not doing things 2 and 3 times. G%%R I reriveted the circle trims for the hood pins 3 times today, Installed the radiator 3 times, windshield twice, the body at least a dozen times.
The decals are on.

(http://i245.photobucket.com/albums/gg54/raiderfan73/P1011592.jpg)
The MANTA decal wanted to curl at the edges. I think it's because of the printing over the vinyl. It seems better now after a couple of days.
The body foam is cut and installed. It really couldn't look more crude, but that's exactly the way it was originally.

The pipes are in.Awaiting new springs. dead horse They fit like ass, but it's better than they were. I raised the radiator 1 1/2" and moved it to the right an inch.
 I need to fix the radiator mounting, the radiator is crooked. &!!@!

I had some heat tape given to me, so I wrapped what was close. I'd feel more confortable with a litle more, but we'll see how things work first.
  You may notice the coolant lines are done also. A head scratcher even with having the old ones. ??hed?
  You can see I had to cobb the radiator mounting. I'll rework the mounts later.  I need to borrow a welder from a friend.

Learned a little about the sled at the Whiteout. First I met the guy that was bidding on the sled against my friend that got it for me. First thing I did was shake his hand for quiting bidding.
  He and his brother told me that the original owner had pin striped the sled himself. As a matter of fact he over pin striped most of his stuff.
  They really liked the fact I put Dick's name on it. That was really satisfying. Better than any trophy.

Hit a local show last Saturday. No better way to spend a birthday then a nice day at a sled show and a few cold ones.
  I think I talked to 4-6 guy's that knew Dick. They had some great stories. Helping him load it up for the races with his wife, seeing him buzzing down the trail in it with a grin from ear to ear.
  Most commented on that they liked that I put his name on the sled. One guy told me that Dick would be happy the sled is restored. Got a little chocked up, I have to admit. Better than the trophy I got any day.

  Almost had a little mishap with the sled unloading it. I figured I buzz the yard one time and pull in the garage. No skags so steering is not the greatest. I mat it out of the corner, just to have the throttle stick WFO. I'm glad the dirt pile is there as a banked off of that, through the weeds.  I'm also glad the juice brake works now, 10 time's the charm w1nc, As the sled, and controls are a new set up for me, gas pedal and no kill switch, just a tether. It took 50 yards or so before I got my wit's and pulled the tether.
  The gas pedal has enough side play to get wedged behind the stop.  doh. That will be fixed before any more hot laps. Boy that's a bad feeling as your trapped in there. No way you could bail.
