Cat 941 B Serial 80H04086, 2P6776 engine arrangement, engine serial 78P1842. Had a major overhaul 1300 hours ago with major block work. #2 cylinder is dead. Upon disassembly found #2 had a severely bent exhaust pushrod, oil/fuel in coolant system, crack in head on #3 from injector to valve. Head gasket appears not to be blown out or deformed. ONE GASKET--NO SPACER PLATE. Everything looks good on bottom end.
My parts book has head part # 2P6274. I don't have access to see if this number was superseded to another number. The head I pulled from the Cleveland Bros. overhaul has a casting # 2W654. My research found one listed for a 3304 as 8N1188 PC/SP for casting # 2W654. I am assuming that this means pre-chambers and spacer plate. BUT I DON'T HAVE A SPACER PLATE!!!
My question is what is the correct part # ??? Can a spacer plate head be used on a non-spacer plate engine?? How did the oil get into the cooling system??? What effect does a bent exhaust pushrod have on the flow of fuel/air through that cylinder??? I tend to think that the air would be trapped with additional fuel being added with each cycle. That fuel has to go somewhere. It did make a lot of white/blue smoke.
I thank you for replying in advance. I sometimes get a little baffled trying to figure stuff out. I thought this was a good one for you experts. Will be purchasing a NEW head as soon as we get this figured out. Thanks again.
