chrisbalich I like it. Honestly, it doesn't seem all that different, maybe a little smoother power delivery.
So as expected, once out there were all kinds of issues.
The linkage on the motor was mostly seized up, that's what caused the original problem. Replace those bushings with the copper ones if you haven't.
The pop-off valve had been installed incorrectly, so that if it needed to pop it would hang up. That's fixed.
The cat was trashed. The old heat exchangers were rusting up.
The transmission looked great - at first glance. It had been rebuilt at some point. I always had trouble with 1st and 2nd but thought, well, you know... 915.
Turns out a part was on backwards and was chewing off the dog teeth on 2. So that came off, got flipped to the proper direction, and 2 was repaired.
Replaced the clutch and all the various parts while it was out.
