Getrag transmission problem on low mileage Fiero GT (Page 9/17)

Re removal of blind bearing race above. The well heeled among us may seek a special bearing removal tool that (apparently) bites the ID of the race and includes removal screw. I removed mine with a 30 minute heat soak in the kitchen oven. Do not exceed 275F. The race will drop out

Moar. Although you have smoothed the shaft journal the pitted area is a hazard to the seal. I would try to make some careful measurements of that (abrasive) journal area vis a vis the seal lip seating area and avoid that area when positioning the seal. Seems like that is doable, no?

Hi,

thanks for all your replies!

One popular way is to weld around the ID of the race and when it cools it shrinks slightly allowing it to be pried out.

I´ve also thought about the welding method but unfortunately too late (after I have removed the race).
However, I think with the welding method you also need a special tool (like a dent puller hammer) for pulling the race out of it´s seat.

I guess due to wrong storage of the transmission (high humidity) a recurring
water film between shaft and seal caused the corrosion on the input shaft.

I don´t think that the input shaft seal rides EXACTLY on the same surface as before, because I have
mixed the bellhousings which results in slightly different tolerances (hopefully sufficient axial seal offset).
What you mean with seal positioning?
I thought this seal lies in a groove and so you cannot change it´s position?
It might be possible to shift the whole input bearing/seal assembly slightly in it´s seat.

In the meantime I have already put together my trans.
Now I´m hoping that the input shaft will not leak to much!
(I will use high viscosity oil for “improved sealing”

)

BTW, IIRC is an internet / SMS abbreviation for “If I Recall Correctly”.
There is an abbreviation for almost everything out there!
I also don´t like too many and complicated abbreviations.

Tom, you wanna know a NOS source of original Getrag 282 diff shims?
I have spent weeks of research for finding NOS shims.
There are quite a few online stores which are caliming that they have these shims stocked (like Gmpartsgiant, etc.).
However, when you place an order there then they cannot ship them!

Now the valuable tip for Fiero drivers:
Get these shims at FinditParts.com for a reasonable price ($26.-)!
(some GM 8672904 and 8672905 shim kits are still in stock)

Another source is WhiteRacingProducts:
http://www.whiteracingprodu...&products_id=1221219
http://www.whiteracingprodu...&products_id=1221220
(still 4 shim kits in stock)

Shim kit #1 ( # 8672903) is already out of stock everywhere!
I have ordered kit # 8672904. (you can grind some shims in case they are too thick for you)

I can't seem to make it quote the welding thing. I don't think you still need a puller. When you weld something it heats it up and expands and when cool shrinks. Since it can not expand it only shrinks as it cools. I've never done it, someone told me this trick. Certainly use a TIG weld. It may not fall out or maybe it will but it should not be a problem to get it out.

What you generally would want is a selection of shims. Thin to thick. You add (stack up) as many as needed to get the correct crush (turning resistance). I have a selection of these shims here I bought when I used to offer a Getrag rebuilding service from a local trans rebuilder in Milwaukee. I used to know what year and trans the Dodge shim kit was. I can't find that in my saved notes on the Getrags. I have wondered if I could put a Getrag shim kit together. A multitude of thicknesses. Precision shims are somewhat expensive. If I sold a shim kit I would probably need to make each kit very generous and then let the customer return what they did not use.

You and your trans rebuilder have used diff shims from a Dodge?
It´s a pity that you can´t remember about any details.

Was it a Dodge Stratus?
Maybe sardonyx247 knows more about these Stratus shims...

I used to work for a large German company and we assembled many gear boxes and stuff. We stocked large amounts of different size and thickness shims. We bought in such bulk they we cheap and they sold them to me at their cost. Was many, many years ago.

It was either an 92 or 94 or a 02 or 04
I know vauge, but it did show up in the parts break down.
There is also alot on ebay under "getrag shims" If you can get a diameter, I can compare to the ones I have.

Just sell one at a time, have them measure the thickness first, then just order one. It will keep more shims selection in stock for you/fiero owners, and people really don't need a whole kit but just one.
