Someone order one. I'm like 100% sure they will tell it is no longer available.

Thanks hobbywrench - very valuable information!

Some Muncie 282 rebuild kits are still available, but often some parts are missing...

Example:

eBay - MUNCIE 282 FWD FIERO REBUILD KIT for US $89,95



Sellers reply about included parts:

Obviously not a complete kit, but anyway it´s a good price I think and sufficient in my case (hopefully).

With the input bearing missing, the big retailers can no longer sell the 'kit'.....so it makes sense that the rest of the parts show up on E-bay. And most of the input bearings will be missing....

The kits are apparently built up by the suppliers as ordered. The input bearing may be available in NOS. Finally put an adapter on my rebuilt Getrag and checked the drag on the turning spline shaft. Only 1st would register on an inch-pound beam torque wrench- 25 inch pounds. The other gears would not register at all. This is less than I remember years back. Don't know if those readings are normal. Maybe sitting for 10 years resulted in handshakes (cold flow) or I expected too much. Maybe it is usable.

I have not seen a NOS Getrag input bearing for many, many years now. Some have looked far and wide for one and could not find one. It is possible there might be a few out there but it is a very rare piece these days.

Just out of curiosity (and I am sure I am not the first) could the input shaft bearing be cross referenced with another one identical ?

That search has been ongoing for about 10 years now, and because nothing was found, Rodney designed and sells a replacement assembly. It appears that the OP does not need it, but in most Getrag rebuilds, the input bearing is bad.
