I have a Caterpillar 977k track loader.
Serial number 11k3729
Block number M 5S6777 29
My engine seized during a run away a couple of years ago. It ripped the rod out of the piston and then shoved the valve through the head leaving the pan full of shredded piston. I believe the best option is to replace the engine. I was told that the metal shavings could block oil flow if I tried to rebuild it.
I am not sure what or where to look for a replacement. I'm pretty sure it's a 3306, but there seems to be many versions of this engine. Can any one explain what I should be looking for? What are the differences in the 3306B, 3306PC, 3306DI, d333, gen sets, industrial vs marine vs truck etc. It's very confusing. Also should I keep the original equipment or swap for a different model? Which engines would be a direct bolt up? I've seen some engines on marketplace, Ebay and some heavy equipment sites, but they have different accessories. Usually a bunch of extra junk that mine doesn't have. Would I just take all of that stuff off and install the accessories from my existing engine? They usually don't have the same intake and exhaust or fuel pump configuration. Also I don't know if I have a scroll or sleeve metering fuel system. I've asked some local mechanics, but no one seems interested in helping.
I am sure I can change the engine myself if I have the correct parts. I have some mechanical background, but I work in construction.
Any advice would be greatly appreciated.
