There are early engines with small main bearings and late engines with larger main bearings, but just to confuse the issue there was an update kit that would put a new crank in an early engine...it had one small main bearing to fit the block and one larger bearing. My 70 diesel has it and was a little confusing til I read the parts book closer.

Murphys Motor service has pony motor main bearings available. Don't know about the thrust washer though. Hope this helps, Mike

From what I remember those V4 ponies all had the same rods. The mains were changed at some time and the size changed. 2 different cranks also because of the main brg. size change.

When the black dash 720 diesels were introduced the pony engines were also changed and had s/n plates on them. The difference between early pony engines and later ones are : bigger pushrods/lifters/rockerarms, thermostats and water pump bypass tubes , larger main bearings and thrust washers and different linkages in the transmission plus a few other minor changes.

That would explain the 4 pushrods that resemble bananas. I think I'll keep the throttle speed down around 4000 rpm. Think it will produce enough juice? I live in CA where below 20 degrees is very rare....

Neighbor had one that had some of those "bananna" pushrods along with broken rocker arm shaft. Had to of killed off a couple of cylinders. Funny thing was it would still start the diesel engine up !!! Just stuck some used good parts back in it and kept going.

Oh, and I usually get asked if its an early or late pony. Tried searching for those differences, and from what I gather, it's just the rod's???? Or are htey referring to the R pony which is obviously different....
