Well, I just bought a 1978 Case 995 for 1500 bucks. K noticed it was a bit loud when running. The oil pressure was around 20 pounds when at an idle. I only ran it for a max of 10 minutes. I changed all fluids and filters. However yesterday out of curiosity I pulled the pan to look at the guts. Well, I found the thrust washers in the pan with a gob of shavings. But this is where it gets bad...... the PO apparently ran it for a lllooonnnggg time like this. Its ground the thrust bearing groove off the main cap, that can be replaced, however it also ground the groove from the block. So I need to know if I can run a half thrust on that main or if there is another fix. I'm a very knowledgeable mechanic. Cert. Diesel mechanic, cert. Welder, machinist, if there is anyway to fix this PLEASE LET ME KNOW!!!!!!
