Can any of you with automotive gearbox experience help me out please. For
experimentation I am looking for a planetary set to make a PRSU for a 40hp
engine. Something similar to
http://community-2.webtv.net/SkyWarrior/PlanetaryReDrives/index.html but
with a Motorbike rear hub rubber block style damper between the engine and
PSRU rather than the spraque clutch.

Desired attributes of this planetary set would be:
Common as dirt (cheap :)
Preferably German or French car, as they are more common here.
Straight cut gears
Small ~around 5 inch bell OD.
Bell gear part of a forged shaft which is about 8 inches (20cm) long and 1
1/2 inches thick (this would end up the prop shaft)
~ 3:1 when driving the sun, holding the planets, with driven Bell.

Is it imperative to keep a rubber block style damper oil free? If I don't
have to isolate this from the oil system, it makes sealing a whole lot
easier.

Soak a sample of the rubber in hot oil.
The Jatco auto transmission used in Mazda's, Toyotas and probably several
other Japanese cars appears to be a scaled down Ford C6. Jatco was a joint
project between Ford and Toyota.
