Super C oil pressure again

Anonymous-0 · Jul 27, 2010

In one of my recent posts i was told to try machining and putting a new gasket in the oil pump because of low oil pressure. What exactly does that mean. Do I have to pull the pump and take it somewhere to be machined. Where do I buy a new gasket for it.

CaseIH has the gasket. If no local dealer, Carter and Gruenewald, CIH dealer in WI that does mail order, 866-327-6255. Although I have 3 of those engines, I have not done one. I believe the procedure is to put it on a flat surface and sand the bottom plate.

It's quite simple. If you remove the engine oil pan you'll see a strainer hanging down that the oil is sucked up through, I believe it's retained by a single cotter pin. Once you've removed that you'll see that the bottom plate of the oil pump (which the strainer hangs from) is only made of pot metal. Often they warp/wear and either allow enough oil to bypass and cause a pressure issue or due the warpage the gasket will blow out. Remove the four bolts that retain the bottom cover, be careful as one of the oil pump gears will also likely fall out. Once you have the cover plate off you can either get it machined flat, use a piece of course emery cloth on a flat surface (such as a robust sheet of glass), or if you're very good file it flat. Hope that helped, Sam

Set end play with thin gasket material,(caseih has gaskets) .001 to .0005" is a good range. Jim

If you'll remove the complete oil pump assembly and support it upside down in a bench vise, you can then remove the bottom cover without the gears falling out. (just a hint)
