Transmission play

Dave3d · Posted: Tue May 15, 2012 8:06 am Post subject: Transmission play

Hello.

I was pulling a bit on the transmission shaft (where it splines into the engine), and notice quite a bit of play (maybe 1/4 inch? ) when I pulled and pushed on the shaft.
Is this normal?
I dont remember my bug having that much play.

Thanks.

Dave

Not normal. Serious damage imminent. Take off bell housing and reattach/repair the input shaft.

In out? or side to side?, the rear end of the input shaft isn't supported when the engine is missing so side play is normal, end play may be the beginning of bigger issues and could be worth a look inside.

In/Out.

Not side to side.

Shifting has always been a bit difficult in 1st gear, and is really sloppy in all gears (seems like a mile and half to each gear, up, down, and to 3rd).

in/out play is not good - I don't recall the endplay specs but it's no where near 1/4"! More like .0xx" - my guess is that the bearings are shot - at least that would be the cheapest fix - time to pull the tranny apart and repair/replace all the damaged parts - I'm going to guess with that much endplay you'll find metal shavings in the oil and if it's been run for a long time it may have damaged other bearings and parts (countershaft bearings, etc.)

Poop.

Well, looks like a rebuilt from rancho.
Sad

Thanks all.

Could the tranny mess up the engine if I put the engine back in and drive it to the shop to have the tranny replaced?
What kind of damage could occur?

Not likely, if you already have the engine out why have a shop do the transmission pull?

Well, I am not physically able to do much on anything right now.
I am recovering from 8-11 blood clots in 1 leg, a massive pulmonary clot (that has resulted in heart and vein damage), and tons of smaller clots throughout the lungs.

So:
1. I just dont have the strength or stamina for pulling a tranny (I pulled the engine myself, but I also didnt have to do any strenuos work for that). I cant even get the engine back in by myself. Sad

2. I know absolutely 0 about trannies. I can rebuild an engine, but trannies baffle me.

Thanks guys.

Well, I am 4 months out now.
the leg clots should be gone.
All of the little lung clots seem to be gone.
And, I have more good days than bad days now.
But, I just dont have the stamina/strength to do stuff myself.
My sister just came to live with us, and she is w/o a vehicle.
If I can get the bus going, she can drive it until she gets on her feet.

That way, I wont have to spend 2,500 on a car for her. (which, looks like I am going to end up doing anyway).
Smile

Plus, being lazy is what got me the clots in the first place.
Trying to move/work/get-off-my-ass as much as possible nowadays.

There are 5 different things to look at in regards to excessive
endplay on the output shaft.

The 2 most common being.1-Thrust surface on nose cone worn
but repairable.*
2..7mm Stud is unscrewed from mainshaft.*Also repairable

Then we have 2 snaprings that hold 3rd gear and 4 gear Which is Not
common for them to fail.
#5 is the mainshaft bearing in the shift housing.
This is what pounds the nose cone....

Please look at illustration #10 in VW transmission diagrams
@ www.longenterprises.com
Was this trans noisy before you found this problem?

Nope, no noise.
Just hard to shift into 1st gear, and very sloppy in all gears (my bug is very tight, with very little movement needed between 1st/2nd and 3rd/4th, and in-between 2nd to 3rd). The bus has a LOT of travel from 1st/2nd, and 3rd/4th, with a lot of travel going from 2nd to 3rd.
It just all feels very sloppy
The coupler has been recently replaced (as it is all new and shiny).
