I'm swapping an engine that was set up for a manual transmission back into being an automatic. I need to put this bushing, or whatever it's called, into the end of the crank so it keeps the torque converter centered... or that's what I'm guessing it's for. Does anyone know the name of this thing? I went to the Audi/ VW dealer to order one, but all they came up with was a needle bearing, and it didn't look the same on the part diagram. It would be tons of help if someone could identify this, then hook me up with one they have lying around, as I assume this is the same as for the 1.6.
BTW, this is from an 83 Audi 5000 TD engine.

I would call it a pilot bushing, but what matters is what they call it...
But I have never seen a pilot bushing for an automatic (?) It doesn't seem as though there should be a need for such a thing at all....
-
Yup, I'd call it a pilot bearing... it holds the tranny's pilot shaft. I believe it's a Vanagon thing, since the Vanagon has the more traditional clutch.
Hopefully a Transporter person will weigh in to clarify. ;)
-
Thanks Andrew. Looking at it more carefully there's no evidence of "bearings" in the picture, now that you mention it.
While we're on the subject...is the pilot bearing a Transporter thing or more of a non-transverse engine/clutch thing... ie, have you seen pilot bearings in Quantums as well?

What would the symptoms be if this was not installed? (the bushing the OP posted)

spigot bearing http://www.google.co.uk/search?hl=en&&sa=X&ei=seliTLvJD9OC4QaXt82DCg&ved=0CB8QvwUoAQ&q=spigot+bearing&spell=1 (http://www.google.co.uk/search?hl=en&&sa=X&ei=seliTLvJD9OC4QaXt82DCg&ved=0CB8QvwUoAQ&q=spigot+bearing&spell=1)

Yeah this is no bearing at all. It's all solid. I was going to have someone machine me a new one if I couldn't track one down. It is strange though that the only thing on the parts diagram at the VW/ Audi dealer was a "needle bearing."
So is a "Spigot bearing" a british-only term? I've never heard of it before.
-
Haha, alright, well thanks a lot! That parts guy ordered part 10 on the diagram.
I appreciate the help!
-
There is a bearing or home-made brass bushing in the end of the crankshaft that will have to be removed before installing the new bushing.

This would be the end result. Symptoms?
Premature failure of the transmission input shaft bearing.
To picture this you would need to think of a situation where the clutch pedal is depressed freeing the clutch disk from the firm grasp of the pressure plate.
You have a big heavy clutch disk spinning on the end of a 5" to 8" shaft at 5500 rpm. If there is no support on the end of that shaft (in the form of a pilot bearing or bushing) it'll tend to flop around all over the place. As it's flopping about and you release the clutch pedal the clutch disk won't necessarly be centered in the middle of the flywheel/pressure plate combo.
-
The bushing pictured by the OP is for automatic transmissions only. I imagine that it's only purpose is to ensure that the torque converter is properly positioned while it is bolted to the driveplate.
My bad. I'll go away now.... :-X
:D :D

this, or replace all the "clutch & pressure plate" with "flex plate and torque converter"
a tq converter is probably heavier than a clutch setup FWIW..

All good, my truck (6.9l) has one of these and is standard and I think it is worn, and my mom's Mk1 auto Jetta makes some awful noises when cranking so I think the torque converter might not be centered. I know I didn't install one when I installed the engine. This is the first I have heard of such a thing.
-
Andrew I just spoke with my dealership and he told me there is no stock in NA. How long ago did you check stock? Would you mind calling your dealer to see if they have it perhaps?
-
Yeah, it IS for the Auto trans, and I did remove the old copper one with the bolt and grease trick. I ordered a new one from the dealership and it should be here by tomorrow.... I hope. I would really love to get the engine in and running by tomorrow night! I'll post pics when it's all finished!
-
I got notified today that the part is NO LONGER AVAILABLE from Audi. I cut off the torque converter on my seized engine though, and stole the one from that. I'll have pictures of the completed car soon!
-
I cringe whenever I hear those words..."NO LONGER AVAILABLE". Those words have been a real pain in my ass. Rather than cringe, I guess you could say I pucker up. Anyway, it sounds like you already have the part you need, but in the future, if you're not in a hurry, NLA parts, or European-only parts, can usually be ordered from over-seas through worldimpex.com. They have a dealer that they work with in Germany to ship special order parts over here. There has been at least 5 times when my dealer told me something was NLA, and I was able to get it through World Impex. They don't charge a ton of money either. Their parts are usually cheaper than the dealer, plus they don't add additional shipping or customs charges. It can just take a while to get them is all. This last time took a month and a half, although it's usually only 2-3 weeks.

Passenger-side parking brake cable for my 1998 Mazda pickup... the one that rusts out *all* the time...including on every Mazda pickup in the JY... is NLA. :o How can a safety system part for something only 12 years old be NLA??!! ::)
-
IT is getting disgusting how many parts are NLA through the dealers anymore.. Especially for relatively new stuff like Vince's truck.. And newer! :o I'm surprised though how often (when you can find the right parts guy) they can still get the part with a few phone calls.. Seems as though they mark it NLA in the computer system long before stocks are depleted.. Sadly the good parts guys seem to a dying breed....
Vince, try your Ford dealer.. Just don't mention the word Mazda.. The last guy I dealt with for parts on one of those swore up and down that the Mazda B series and Ranger were not the same truck..
-
Vince, try your Ford dealer
Yeah, but ix-nay on the Ord-fay... I can hardly believe I have a non-VW in the fleet, let alone something that rolled off the... gasp... Ford assembly line. ;-)
Sorry OP...we're off topic.
