Jack,
Thanks for taking the time to share your knowledge. I copied the
list because this is such good information.

I just bought a snap ring plier set... worked great on the input
shaft ring. For the mainshaft front end ring I had already
stumbled on the prodedure you describe with the multiple
screwdrivers before I bought the pliers... Took an hour and a
half.

I distorted my third gear circlip beyong reuse as well. My plan
to get it back on.... is to use the snap ring pliers to spread it
as best as possible and then shimy it down the shaft and then
just get inventive to get it into the tight space on the inside
of the 3rd gear spacer.
Any advice on this.

Thanks for the advice here. I am going to do this test today...
I will be extra careful.

Based on the list and reading... I ordered a new
layshaft(countershaft) as part of my rebuild set.... but the one
in the transmission is in good shape... shows no wear... for that
matter the needle bearings seem fine as well. Should I replace
the shaft anyway... yes seems like the right answer.. but maybe I
should return it in exchange for a new third gear part. Or bite
the $34 bullet and replace both.
I HAVE BIG PROBLEM HERE..... I can't figure out how to get the
old needle bearing assembly out of the layshaft and the input
shaft. I broke the input shaft one and the needles all fell out
trying to bash on it. It needs something with a hook to go
behind it and an impact puller type of arrangement. An impact
puller kit from NAPA is $99.00 and they have to order it... Sears
has nothing.. store or catalog. I am off to the the hardware
store this AM to see if I can make some sort of homemade thing
from the old rocker shaft or a threaded rod with a grade 8 washer
on the end and a piece galvanized pipe as a slide ram. It won't
take much force to get them out... it just needs to be applied at
the proper point.
What do you use???

Thanks I will pay attention here
