This must be Dick's D7E repowered with a D342 engine. Looks like a really well done fabrication.

Man, I would love to hear it running.

When I read the original post describing this change over, my initial thoughts were that the tranny might not live long. This was based on info Ozdozer had posted some time ago describing how the D7F had a 3306 engine but used the D7E transmission. The early versions had a lot of problems until a D6C tranny was substituted along with changing the final drive gearing. But that was the power shift version and maybe the direct drive will do better.

At any rate, did I mention that I would love to hear this hydrid running? hint hint

Hi Team,
that is a really neat conversion.
I really like the extended fenders.

The early D7F's, fitted with the old D7E trans's, failed mainly because of the old big planetaries not being able to cope with the extra approximate 1000 engine rpm's of the D333T engine. The trans transfer gears were another weak point.
As was stated above, Cat soon came up with a beefed up D6 trans that fixed all the problems and performed as well as it had in the D6. I was running the Trans Shop at The Dealer when all this came about.
Cheers,
Eddie B.

That D7E with the propane tank on the front is one slick kitty as well. Dick rigged up a propane sniffer for those tough spots. It is still a 4 cylinder. Thanks for posting the pics.

Did the late 7E's have about the same transmission as the 8H's?

Nice Cat, I see its got a Spokane rock guard on it
