I dropped the oil pan this morning and discovered the #3 rod bearing had spun but appeared to only do some minor scoring to the crank journal.

Thanks to Gunn Automotive :bowdown::bowdown: I had a new set of rod bearings and oil pan gasket by Noon for $33!

Ricardo came by to help and disassembled the oil pump and discovered it was worn way beyond tolerances. That makes sense because when we went down some really steep hills in Moab it would suck air and lose prime, sometimes it would take 15 minutes to start pumping oil again. I think that is what happened on Monday and the girls drove it without oil pressure long enough to eat the bearing.

Thanks to Dr. Schlegs I also got an oil pan with no extra holes and a 2F oil pump. We took it apart too just to be safe and it was in MUCH better shape than the Mules original pump. We buttoned it up, poured in the 15w-40 and she started right up with 50 psi pressure. Once at full operating temp and running down the road it was maintaining 40-45 psi and everything was quiet. So, hopefully, the Mule is back in service and ready to roll.

Ricardo was wondering why I didn't just drop in the new 2F motor I have. I told him the engine in the Mule is like an old horse, I just can't bring myself to shoot it and put it out of it's misery. It just keeps on going even after being horribly abused, you gotta love the old tractor motors.

The clearance specification between the gear teeth is .037" maximum. The old pump was way beyond that. Interestingly enough, with the gears flipped it would be back within spec. You could see the wear on the gear teeth. Inspection of the new pump came in well within the tolerances, I seem to recall it was right at .023".

It is a good feeling to hear the Mule fire right up, run quietly and have good oil pressure. It should be "good to go" for the wheeling Dee and Randy have planned over the next couple of months.:D

Good to hear, and Ricardo and Dr.Shlegs come to the rescue for yet another member.

Rescue - I don't think so. Randy did the heavy thinking, lifting and working. My part was a bit more akin to jumping in front of the parade and to get on camera:D. I do enjoy the time I spend in Randy's garage; working on the Mule, my truck or whoever's. Yesterday, I was able to get a good look at how the oil pump block is attached to the engine and how it may be contributing to my "snapped distributor" issues.

I guess I'm Robin???? I was thinking more along the lines of Wolverine though.
