M and 560

[trailridr]

Is an M engine interchangeable with a 560? I've got a good M engine will it fit a 560 with a bad engine?

Hello trail welcome to YT! So the 560 is something you
see for sale? If so I would not recommend purchasing it
based on the fact that you have an M engine to use in
it. The M is a 4 cylinder engine and the 560 is a 6
cylinder. There would be a fair bit of modifications to
make the M engine fit.

560 rated at 1800 rpm engine speed. M rated at 1450 rpm engine speed. You would not have a usable power shaft for most pto driven equipment besides reduction of power
from original 560 engine.

Not a desirable swap. beyond a bunch of work, it has way less power. Sell the good M engine and use the funds toward a rebuild of the 560 engine. Jim

Skip the whole 560 thing and move on up to an 06 or 56 series. Better tractors with few problems and no rearend issues.

The rear ends on the 560 have not been an issue for 50+ years and the ones that did have issues were fixed then - and if they weren't I doubt they will be after 50+ years of use.

I think these two issues would be the biggest problems you will have as there really isn't a way around them. Upping the RPMs on the M engine is possible but you have a cobbled up tractor already and gained nothing for the effort except the experience. There are a lot of old 263 engines out there in running condition or that could be running with a little effort.

RPM is an easy fix with a pulling governor.

PTO is an easy fix using a 400 or 450 flywheel clutch and pressure plate.

An M engine built with overbore pistons and for high compression can give a 263 a run for its money. Most Ms have been overhauled with the 4" overbore kit which gives them 264ci.
