John Deere engine swap.

Will the engine complete out of a MT John Deere fit into a 430 John Deere. Thanks

I knew someone who had an MT with a 420 motor.

Should slide right in. But Mt. Didn't have a water pump. So radiator hoses are bigger. And no thermostat. So I would use the 430 pump and fittings. If will work.

Why take such a long step backwards ?

The 430 pump will not work on an MT as the MT block has no place made to put it.

Sometimes ya gotta take one step back before you can take two forward....

I had a 420 that someone had installed a 40 engine. I couldn't keep it from over heating because the radiator hoses were smaller. I ended up
putting in a 420 engine. 40 and m, mt, don't have a water pump.

Might be cause good MT engines aren't hard to find but finding a 430 engine that wasn't completely worn out 40 years ago is pert near impossible in some area's. If you find a 430 around here that isn't worn out from top to bottom someone just brought it in from somewhere else.

I would rebuild the 430 and have a known good engine. Rather than risk #1 an used engine. #2 that the M engine is gutless vs the 430 engine.
