MF65 exhaust manifold torque settings

[Darrin Williams]

I'm going to be replacing the exhaust manifold gasket on my 1959 MF65 G176? tractor. Do you know what the torque settings are?

25-30 ft.-lbs. according to the genuine Massey service manual.

thank you. i was seeing about 24-26 as a general rule but it's nice to have the real numbers.

Hi Eric,
I'm not familiar with that engine and if you have the manual for it I would not question that.
However if the studs are 3/8" ---no problem!
If the studs are 5/16" and perhaps have brass nuts AND the fact that you are crushing a gasket, I would look at 25 lb.ft as an absolute maximum.

Hi,
OK, never doubted you. Looks like the manifold bolts/studs are 3/8". Out of curiosity is this correct?

Cheers

David, I didn"t remember the size so I ran out to take a look. Thought I would just take a picture while I was at it. Yes they are 3/8 , though you may not be able to tell that from the picture.

Here is a complete picture of the tractor, the one I learned on forty some years ago. I painted it and overhauled the engine about twelve years ago. The motor and transmission is starting to need paint again, but it gets used like a tractor was intended to.

Hi Eric,
Thanks for that. Yes, can see that they are 3/8"!
