Re: (ET) E20 transmission whine and overhaul advice request
If it is of interest, I bought an Avco/New Idea Transaxle Shop Manual from
Bill Gunn a year ago, when my E10M transaxle had to be rebuilt. It says it
covers all the ET models Transaxles; it is about 60 pages (probably
xeroxed)
with some pictures and lots of drawings. It cost about $25 with shipping.
It
was very helpful to us.

Yes, I do. After my Sys. Admin. conquers her latest internet
disaster,
I shall ask her to scan and post the images on her server . Stay tuned.
As far as the noise is concerned, let's face it, the Peerless
transaxle
isn't exactly a piece of precision engineering.If you really want to quiet
it down, it can be done, but it IS tedious, and time consuming . Adjusting
the endplay, for each assembly, separately , is the ticket.
Plus, a larger bearing is available for the input shaft.
Other modifications include having the case machined, to accept
Torrington?®
bearings in some locations, in lieu of thrust washers.
The loose gear concern can be remedied with a VERY thorough cleaning
of the affected parts, and reassembly using 640 Loctite?®. The thorough
cleaning aspect can not be over stressed . As you will find, the materials
chosen by Tecumseh?® were not of the highest quality, and the gears are
quite
porous, making oil removal difficult.
If you decide to spend the time, the result will be a tractor that is
eerily quiet. With even normal ambient noise outside, you CAN sneak up on
people.That's the fun part, especially if your tractor has a VERY loud horn
on it !<G>
