Getrag transmission problem on low mileage Fiero GT (Page 6/17)
hobbywrench NOV 06, 10:54 AM
I should add the best source I found did say when he "builds" a kit he personally inspects for Chinese bearings which apparently can find their way into these kits. I asked him if any Chinese bearings are acceptable, and when he thought some Chinese stuff would improve like Japanese did. No real answer. So I guess we will have to use US ingenuity . The Cubans have kept 1950's cars running, after all.....

I looked for a drawing of the input bearing. SKF has a 453 pp index, but skips over that bearing. We need to create a drawing for quote, or find something close that can be adopted.

Thanks gall - yes I have seen Rodney's replacement for the input shaft which is a clever piece of kit.

ok so maybe not to try and sound naïve or stupid here so maybe not to cross reference with another manufacturer but maybe getrag produced another gearbox with that same input shaft bearing or has anyone looked at the new mini with a 282 getrag in ??

again this is like the taillight saga.

just a thought

Which Mini Cooper model you mean exactly?
I thought the 5-sp Mini uses the GS5-65BH transmission?
Are there also newer models with a Getrag 282?

I just googled for basic info but have a look - it looks like the first generation mini cooper 2001 to 2006

when I last posted about the input shaft bearing being used in another getrag I am thinking in terms of the manufacturers like for example a chevy Camaro uses the same wing mirrors as those on a fiero and so on

Yes, I know what you mean with part cross referencing.
Unfortunately nobody has found out which alternative bearing could be used for the input shaft bearing (GM 14082181) instead.

But look at the following pictures, the front input shaft bearing/seal is a special bearing:




Therefore, it is so difficult to find an alternative for GM 14082181 bearing.
Of course, the same input bearing is also used in many other cars (see page 1, post 19).
However, if you search a tranny rebuild kit for example for a Chevy Beretta, then you
will have the same problem and won´t find this input shaft bearing (except NOS).

I think also Rodney has already spend a lot of time for input shaft bearing research.
He hasn´t found a "plug and play" input bearing as alternative for GM 14082181, therefore he has
made this special input shaft bearing kit where a bearing from later internal slave Getrags is used:

This is how the 2002-2004 Mini Cooper input shaft bearing looks (5-sp GS5-65BH):

Alas the Getrag MG-282 input shaft bearing looks completely different.

Hope my input bearing/seal/sleeve is in a acceptable condition.
I don´t want to replace it - this will save me a lot of money.
(rebuild kits without input shaft bearing are very cheap!)

BTW, in the meantime I´ve found out that there is also another way to remove the tranny.

Details described at Fiero Factory - Tech Area "Easy Transaxle Removal":
www.thefierofactory.com/qaeasyremoval.php

With the Fiero Factory tranny removal procedure NO engine or cradle removal is required!
It is a detailed description, but mainly related to 84 - 87 Fieros.

If this removal method is also not much more difficult on a ´88 Fiero, I may rethink may plans
about engine rebuild / swap for this winter. Alternatively I can remove the tranny as described by
Fiero Factory, change the bearings and bolt it back on my 2.8L engine.
Then my car will run again after winter vacation!

The planned 3.4PR rebuild / engine swap can also wait for next year(s).
My 2.8L engine is a low mileage engine (47.000 miles only) and should run a few thousand miles longer before disposal.

Has someone tried this tranny removal method on a ´88 Fiero?

Yes...it works, but it's easier if the car is way up in the air.

I'm not exactly sure what you're trying to avoid with that particular method of tranny removal, but when I pulled the tranny from my '88 Formula, I left the front of the cradle attached and pivoted the cradle down at the back. Worked out fine. From what I understand, this cradle "pivoting" method of tranny removal is pretty common.
Moar NOV 09, 02:13 AM
Initially I thought it is a must to remove the cradle from the car completely in order to remove the tranny.
I have read this somewhere in another thread.

I have never removed a tranny of a Fiero, therefore I was unaware of this removal method.
Removing the tranny through the wheel well seems to be less work than removing the cradle completely.

It's been a while, but I removed the cradle with the engine suspended across the strut towers. The removal provided opportunity to paint the cradle.

BTW it is clear now that once the mystery of "the kit" is broken as it has been here, who needs someone to provide a "kit?" In fact to me there were other wear items I bought that should be in a "kit" anyway. Build your own.
