MH44 EFI Cranks Again

David G · Jan 17, 2016

I got the MH44 to crank today, sounds real good with the new starter.

Oil pressure popped right up.

I have to put coolant back in, install fuses, get the power steering hoses and a tee for the fuel and it is ready to run.

I was wondering, there used to be some dialect confusion on YT, to some people crank meant to run! Looks good! What triggers the coils to fire and how does an advance work in that case?

David G · Jan 17, 2016

Yes, cranks but not run.

The computer fires the fuel injection and coils, but I have those fuses pulled.

I do want to comment how smooth and quiet the gear reduction starter is that I got from Goldberg.

Russ from MN · Jan 17, 2016

OK, so the computer knows the rpm and advances the spark as needed? Pretty high tech old tractor! Thanks for the pictures.

David G · Jan 17, 2016

There is a crankshaft sensor that determines position and RPM.

It is my hobby, a couple years in the making and never done.

Beautiful...

Is there a THREADED proximity probe that senses the TEETH on the Ring Gear? What is the clearance between the end of the sensing device and the reference point? Did you set the clearance of the pickup with a VOLT meter or a feeler gauge? My experience is, the THREADED proximity probes, were 32 TPI.
Thanks

Imagine Massy having that technology when it was new. It would have been unbeatable. Jim

I am amazed at DavidG's ability to adapt such new technology to such old technology--that 44 is a 1940's design!!

I have a toothed wheel and pickup sensor on the front of the crankshaft.

I see you got the oil filter relocated. That whole thing looks great! Excellent job!

David G · Jan 17, 2016

The combined knowledge base from everyone on this forum amazes me everyday.

Great I have really enjoyed seeing your progress on this project. My Grandfather was a Massey dealer beginning in the late 40's. Those were strong old tractors.

David G · Jan 17, 2016

I set the proximity with feeler gauge, .015 on closest, so that allows a little runout and still work.
