Will a gas engine from an Oliver 77 bolt into an
Oliver 1550? Thanks

The engine will bolt right into the frame with the four bolts.And I think most the rest will interchange.

If you need to use the PTO, you might want to check what engine RPM a 1550 needs for 540 PTO speed. The 77 engine runs slower than a 1550. It might not be able to reach PTO speed or may not have much power if it can reach it. I don't know if a 77 engine will have a tachometer connection.

ss55 is correct - the 770 engine won't run quite fast enough to get 540 RPM at the PTO. The 1550 single-speed PTO has 15 teeth on the pinion and 61 teeth on the driven gear. 770 has 18 and 58 teeth respectively. I had the same issue as my 1550 diesel has a 770 engine in it. J. Schwiebert put me on the right track - you can change the gear ratio, I did it, but it's expensive.

it is easy too raise the rpm , in a engine just lighten the gov, weights up
