Transaxle stand

[tjet]

What do you guys recommend for a transaxle stand for a trans rebuild? Do they make an adapter for an engine stand?

Or would this be a better option?

I have done a syncro and 091/1 transaxle without a stand. If I were doing them for a living a stand would be helpful. The more important tool is the one that bolts across differential case for setup. I fabricated that. I used my bench till I was ready to drop the differential case back on. I use a bbq grill to heat the case to ease in assembly.

Thanks.

Do you have a p/n for that tool? Also, any other must-have tools for a transaxle rebuild?

This is in reference to my trans failure in New Mexico

I built this for a friend, laying on my back, under the van....

Luckily it turned out to work very well in the shop!

Note those four nubs that this unit grabs onto.
You can drill holes in them and bolt the four arms of a 'normal engine stand' to the gearbox case.
That's pretty easy way to do a seldom gearbox job.

Tjet, which transmission do you intend to rebuild, Air-cool or Boxer?

I use the bench, floor, and my press, depending on what step I am in. I also have an old umbrella table which works as good as the bench.

I've either purchased the necessary tools or fabbed them.

Fabbed tools

-stand for the gear carrier (press purposes)
-tool for holding the main shaft to torque the 1st gear race nut
-tool to remove the race nut (purchased from a guy in Quebec)
-tool to push out the pinion shaft/big pinion bearing
-tool to remove/install the side screw adjuster
-several different tools for use with the press as necessary

--- Stand on the list now.

I did purchase a Jig for setting the gear adjustment in the DK and earlier air-cool transmissions. But, as I understand, a Jig is not necessary for setting gear adjustment in the WBXer transmission (091/1)

Of all the specific tools, you really need the big pinion socket.

I always pressure wash the outside of the transmission before opening it.

I really like that mount idea, which grabs those tabs. I think I can fab that up. I will also add a stub in the middle to fit into my floor jack.

I'm trying to find the trans code. I broke the locker thing off when I pulled the trans. I was on my back & didn't realize how heavy it was...

Andy, it's a syncro locker trans

I'm guessing I will need this too

That other unit is for a pro-shop.

Not my place to talk a feller out of a project....
but I would think you've got bigger fish to fry.....
rebuilding a gearbox out of a storage shed 2,000 miles from home?

One of the steps is the final torque of the pinion bearing retainer nut. I made a tool out of 90 degree steel angle scrap. It bolts to the bottom of the differential case and clamps to the bench top. It hold the case secure while you torque it. Has to happen quickly before the case cools. It might be hard to torque it on a rolling engine stand.

There is an assembly step on the syncro a stand would be helpful. I think it might have been the rear cover. You need gravity to hold something like a shim or bearing while you install the cover.

I purchased the diff bearing support tool and the pinion bearing large race nut tool. I also purchased the fixture tool that holds the pinion while you torque the nut that secures the pinion bearings to the pinion shaft.

For ease of setup. It massaged another set of pinion bearings so they slip onto the pinion shaft and into the case. It took 5 or 6 swings to get the pinion depth correct.

There is a tool you bolt across the differential case for setting differential bearing preload and back lash. It takes the place of the bellhousing. It keeps the case from spreading so you get correct and repeatable readings. You’ll need some pinion marking paste and a dial indicator. An inch pound torque wrench to name a few tools.

Well worth the investment.

The trans I want to rebuild is a spare unit that's been sitting in my basement for a few years. I will ship out the "rebuilt" spare to the storage facility in New Mexico where my van is (hopefully by summer).

I just checked - the 2 tabs on the left (passenger side) are already drilled - cool

Thanks for the tool info Mark

Thanks for the kind offer Vanis

Hey old_man, I see you've got a TW. I'm building up an '87 with an XT225 6 speed. Gonna need to back burner it now due to my trans issue

Hey thanks for all the input. I'm going to get this transaxle outside for a thorough cleaning, and drill the tabs for my engine stand. I've already reached out to GT Gears to get some parts moving this way. I will be getting his slider hub, and plan to get his 0.925 4th gear to replace the factory 0.85.

Driving in 3rd at 60 MPH @4400 RPM for 2+ hours I realized that the OEM 4th is just too tall with my 29" tires. I'm not sure what cam is in this mystery 2.2 wbx I picked up a few years ago, but the engine really wakes up at that rpm.

I will take lots of photos and start a thread on it.

Cheers,
Tracey

The drilling of the tabs for an engine stand worked out perfect. I have it in my basement.

It has surrendered!

What is that just behind the starter? (above).
