...of the terrible tranny squealing. It's been a while. The
tranny's been sitting on my garage floor partially dissasembled for a
month.
You may (but probably don't) remember that I thought it happened
whenever the layshaft was turning. Someone also suggesed it could be
the input bearing.
The winner was...(drum roll, pun intended)...the roller bearing set
between the input shaft and the mainshaft. Nothing else looked amiss
but both the front end of the mainshaft and the hole in the rear of
the input shaft looked discolored, a bit brown and covered with a
dark brown gunk. The bearing itself can best be described as looking
rusty, especially the cage, though none of the rollers appeared
damaged to the naked eye. Perhaps they were worn. The brass synchro
ring on the input shaft, which would be 4th, was stuck to its cone
but came off with a bit of prying. (I asked it how it's bank account
was doing and it came undone, so to speak.)
Fortnunately the bearing races look good, no pitting or scoring
either on the mainshaft or in the the input shaft. The layshaft
bearings and thrust washers look fine. The layshaft shows no wear on
the bearing surfaces. The main bearings look good.
So the noise would seem to have been happening whenever the input and
mainshafts were turning at different speeds, which means in neutral
and in any gear except 4th. This would explain how I was able to
drive 55 miles home from work in 4th but then have a problem develop
as I was driving through town close to home. I might have seemed as
do to the layshaft turning but I did not actually try every gear
combination and never hit 4th once I heard the noise.
Well, you see something new every day. With a bit of luck it should
all be back together soon. All I need is a few 10-day weeks. Or
some 36-hour days.
