how strong is a hydramatic ?

[doc_cottom]

I have a co worker who is into classic USA cars, and he knows his way into the parts trade.

I was wondering, if i found a cheap Hydramatic transmission, would i be able to get some hours out of it if i used it in a home built wheel loader or a bulldozer, with a 100 hp engine in front of it ?

The Allison automatics of fire trucks are way too expensive to buy used.

It is Torque that breaks parts, not horsepower, or speed. I have a friend running a single engine pulling tractor with a big block 396 Chevy, with Roots blower, on alcohol making 900 to a 1,000 horse power, into an ALUMINUM 2-speed Powerglide transmission, hooked to Spicer class 8 truck rear axle, and the secret, the Sun and Planet speed reducers at the end of each axle. Torque stay low(er) until it hits the planetary gear sets, then speed goes down, torque goes up. If anything breaks it will be stub axle or hub.

(Torque X RPM) / 5252 = Horsepower - If horsepower stay constant, torque will go down when RPM goes up. Remember...it is torque that breaks parts. That is why you see tractor pullers come off the line at such high RPM, wheels spinning. Sound weird, but it works.
