MF 202 Backhoe / Loader

Hey folks, back again with an update and question.
Got the engine pulled out of the tractor, disassembled, and have begun some cleaning. While investigating the low oil pressure / #1 rod bearing spinning and trashing the crank, I took the oil pump cover off to check the gears. It had quite a bit of thrust play in the shaft prior to taking the cover off. Hopefully the picture will upload and you can see what I discovered.
I don"t think the cover is useable anymore. Anyone know where I can find a rebuilt, or rebuilable pump?
It"s the Continental Z134 gas engine.
Thanks for your help,

Roger

The only place I could easily find a re-man oil pump is on thebay site. The 1965 MF 2135 with the Z134 I recently bought not running had a knock in it when I got it running, and no oil pressure also. This is what I found in mine after I took it apart.

Yeah looks like that one is pretty much shot looking at the cover plate wear. I wonder if it could be machined back flat but if the shaft is loose then ebay will have one sooner or later.
 
Yeah 2tractors, I was wondering the same thing about the machining, or maybe filling in the grooves with that same stuff that they use to repair exhaust manifolds, like liquid steel, and re-machining just that one area???

Thanks,
Roger
 
If it's not worn too much you can probably have it surface ground, if it is worn too much a new one could be made. I had to drill the bolt heads out on my oil pump to get the plate off, and where the drill bit hit the plate it drilled easy. I think that plate is not made from any special hard alloy steel, and you can get the re-build kit http://www.yesterdaystractors.com/Massey-Ferguson-35_Oil-Pump-Kit_OPK60A.html
