year change for bellypump pressure (Farmall M)

biggerred · Nov 11, 2013

I know somewhere in the mid 40"s the pump pressure
was jumped from 600 to an amazing 800 from a belly
pump. I"m just short on remembering when. I"m
wanting to swap one on my SM and I have another
that came from a 47 M that has sense been turned
into a couple of Toyotas.

I dont know,but I have a '45 M thats puts out 1200 psi out the belly pump.Verified with 'tester'.

47 probably has the higher setting. Complete unit won't work in a SM though. You can remove the plate and pump from the 47 reservoir housing and install it in the SM reservoir housing.
47 housing won't clear a 12 inch clutch.

Delta, or anyone. What needs to be done to get 1200 psi from an M belly pump?

(quoted from post at 18:56:37 11/11/13) 47 probably has the higher setting. Complete unit won't work in a SM though. You can remove the plate and pump from the 47 reservoir housing and install it in the SM reservoir housing.

If he has the older SM, they had a belly pump.

Understood him to have a belly pump unit. What I was referring to is the change in liftall housings starting on late M tractors and used on SM tractors for 12 inch clutch verses 11 inch clutches. Ones for 11 inch don't have the part of the housing with marks in the picture sloped off as much there. More of a step.
If putting a original 47 liftall reservoir in with a 12 inch clutch the housing doesn't clear.
