Can anyone direct me to an archive on this subject. I searched the best I could and had no luck.
Thanks, Peter.
One of the biggest differences in your tractors is the later one is approximately 6'' longer to allow for changing the flywheel clutch without removing the engine. The extra length shows in the longer track frames, sloped top bell housing, and hood.
As far as the actual D311 engine goes, I believe the engine from your later tractor will bolt right up to the earlier bell housing with no issues or modifications.
If I'm mistaken, someone please jump in and say so... Thanks, Wayne
what i found in my parts books is that the engine block assembly had different part numbers--4F4165 for the earlier machine and 3H9070 for the later machine.

No problen. The later engine will bolt right up.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
