Uncle Vin's 3A
« on: November 25, 2016, 09:49:37 PM »
After years of dreaming about starting my restoration, it's finally happening.  My buddy, Brian Hainer, is doing the restoration. He's capturing the entire resto on video. Here is the link to his You Tube channel.  There are two videos up already. Enjoy - I know I will.  https://youtu.be/1EXMqT2fIoY

Should be a fun series to watch.  I always enjoy learning how skilled folks solve problems.

What do you think of the engine Bob?  Any idea of what it is?

It's a mid to late '30s engine.� Maybe from a Willys 77, or Americar?�

It's probably a chain drive.

I agree, looks like a pre-war car engine.

I have a question Bob.  I've read a little about these pre-war engines.  Horse power output appears to be less (48hp ish) than the war and post war versions.  Do you know what was done to increase the HP on the later versions?  The explanations I've found are kind of vague.

I'm not real familiar with the early Willys stuff so I will go with Jeep expert Jim Allen's explanation.....
"Roos� reliability benchmark was 100 hours at full power. One of his first tasks was to strap the 48hp engine to a dyno. It lasted 22 hours at 3,400 rpm��nuff said. Roos and his staff set to modernizing the engine, incorporating insert bearings, a fully counterbalanced crankshaft, aluminum pistons, a fully pressurized lubrication system, and a revised valvetrain. In just a few months, the new engine was ready for the dyno. It exceeded 100 hours at over 60 hp at a whopping 4,400 rpm. Success! The new engine was dubbed Go-Devil and first appeared in some of the 1939 Willys cars rated at 61 hp at 3600 rpm. In 1940, when the stylish new Willys 440 (4-cylinder, 1940) models appeared, they were all powered by the Go-Devil, as were the �41 441 and �42 442."

Yikes!  That would scare the heck out of me.  I have a tach and never exceed 3000rpm (which is around 50 mph as I recall).  Even 3000 sounds like it is winding up pretty good.  Can't imagine going higher.  Bob, are you saying they would keep it at 4400 constant for over 100 hours?  Incredible!
