General rebuild questions.

[Raider69 102]

It looks like I'm diving head first into Wheelhorse transmission rebuilding. The Raider 12 I recently bought supposedly had a rebuilt trans but is leaking through the case seam and one axle seal and based on some little things I've found on the outside of the trans IF it was rebuilt I'm not overly confident in how well it was done so at the very least I'm opening it up to replace the case gasket and check things out. Next up is my Raider 9 I'm pulling out of moth balls after a 30 year slumber. The trans on it is leaking like the Exxon Valdez and it had a hard life before I parked it. I'm expecting to find significant wear inside it but hoping not to. Then there's the original 3 speed out of my Commando V-8, it may have serious internal injuries, one of the shafts is sticking out the bottom through the case plug. I'm hoping to save it as I need the one I used to replace it to put the CG-7 donor back together eventually.

 

Question No. 1 -  How likely will it be that I have to replace needle bearings? Because on both the Raider and Commando transmissions some of those are very hard to find, and two of the ones I can't find so far are common to both styles of transmission. Are there any cross references to standard bearing numbers? The Raider 12 looks like it was well cared for and was used for mainly mowing. My Commando V-8 was strictly a mower. The Raider 9 however saw a LOT of snow plowing and may have been used to work a garden before I got it. The trans worked well as I recall but it's been a long time since it has moved under its own power.

 

Question No. 2 -  Has anyone made a work stand/fixture to support the 5060 transmission while working on it and would you be willing to share pictures of it? The Commando V-8 trans opens from the bottom so I can just lay it on it's top but the 5060 will need to stand on end.

 

Question No. 3 -  Any tips or hints? I've downloaded every YouTube video I could find LOL.

 

If the Raider 12 doesn't need axle bearings and I don't need to remove any internals when I replace the case gasket I plan to replace the axle seals with the axles in place. My plan is to remove the seals and then seat the new ones using a piece of 1-1/4" Schedule 80 PVC with one end trued in a lathe to seat the seal so it doesn't get cocked and damaged. The ID is large enough to go over the axle and the OD should contact the metal seal housing perfectly.

Wheel Horse parts and More has rebuild kits for your 5060. I'm not sure about the V-8, but I would for sure take a look around and make sure your differential is still usable. @wheelhorseman can point you towards one of his kits. Shoot him a text and he should have what you need.

I don't know who told you that but untrue... or your not looking. Bearings & seals for all uni drives are common as nails & many many places to get them. I even find them in the jungle for a decent price. See the thread posted at the top of this section for cross reference cheat sheets. Also download the manuals in files. 

 

As far as a fixture for working on them some guys just clamp the axle tube in a vise brake shaft side up. 

Personally I have a dedicated mobile work station with holes cut in it so the tranny lays flat and good working height.

Yes use us if  you have ANY questions or issues no matter how stupid you think they may be. Lots of tranny pros here. Since you are a supporter ... thank you... you should have no problems showing us pics of your process. 

This is my favorite manual. wheelhorse_6-8mechtransman.pdf

I've been looking and looking, every parts place I've checked, which is several, shows the same needle bearings as NLA and they don't show up on Ebay in sufficient quantities to do me any good. I found some of the pieces at Wheel Horse Parts and More but didn't see the 5060 kits, must have missed it. I'd be surprised but very thrilled if anyone made a kit for the 5066 in the Commando V-8. They seem to be the red headed stepchild of the Wheelhorse world.

I have a wood top portable worktable I made from an old gas grill frame and I planned to cut some holes in the top to clear crank snouts for working on engines, guess it will become my trans table too. Thanks for the idea.

There is a reference sheet somewhere to cross reference the kit number to your tranny. Maybe @WHX?? or @ebinmaine knows?

the 5060 kits,

The 5060 (and 5073) are different from 8-speeds that came after in only a couple of ways, the limit slip differential and the brake drum positions being the most noticeable, but I strongly suspect that the bearings are all the same as on any 1.125” axle 8-speed. 

Parts and more has the LSD spring, if needed.

Replacing the LSD diff and axles with a standard 8-pinion diff and axle is pretty straightforward. @Achtodid one last year

Quick looks at motion industries had 1532 1542 1529 1531 I didn't look further

 

Other than 1533 bearing the only WH tranny bearing I have not found is one needle bearing in a sunsrtand hydro transaxle .

A cheap HF engine stand can be adapted to hold a unidrive trans fairly easily

I did have to grind the bull gear back some to clear the mushroom gear. Course I used the differential from a 520.

 I'm busted, I didn't check them....  Thanks! Picked up a pair of 1533 brgs. from WH Parts and More.

Not too worried about the differentials, neither of the 5060 transmissions were making any noises but we'll see when I get in there. The 5066 might be a different story.

One thing I should have mentioned is these are a lot like engines don't order anything until you have it opened up and see what you need. Saves time and $$. when you look for parts search on the Torrington part no as in the cheat sheet. For example B-1816 axle bearing is listed as a Koyo but same thing.

 

Looky here a decent price. Lowell has some excellent prices but his shipping kills a dude.
