MH Pony
Anybody know the differences between early and later MH Pony engine blocks?
The early block uses two different oil pump parts than the later block - Stud for the idler gear and pump cover against the block.
Will a pump from an early block interchange onto a later block?
What was the change in oil pump parts and engine block?
I need a new block for an early Pony, and wondering if the two bare blocks are interchangeable.
There had been some weeping of coolant from an earlier repair, and after torching off a ton of JB Weld, here's what I found:
Unfortunately the cracking is severe. There are two cracks, the lower one is about 3 inches long, and the upper one about 6 inches long, wrapping from the side up over the top onto the deck. A bit much for repair.
This block has a casting number of N62A 602
The AGCO Parts Book lists two number in the diagram for CYLINDER AND CRANKCASE:
1500396M92
&
1501099M91
Under description, they only show 1500396M92. This says:
Cylinder And Crankcase Assembly (Stripped), Serial 23379 Up
At the bottom of the description listings there are special notes that say:

Previous To Serial 23379 Supply
1-1501094M1 Stud, 1-1501093M11 Cover
Seems like there was a change to the oil pump, requiring a different engine block, or vice versa
