OM ; my eyes must be crossed I gave head gasket no. the correct is the 2B3712 for ser. no. 2H1-2H8966

I just said I had the books didnt say I knew how to read them

OK,
That gives him the D13000 up to 1940 when the liner # changed to 8B375 plus the D6600 and D8800 series to work with.

So do the 6600, 8800 and 13000 share the same liner, piston and rings? Nobody has confirmed this for me. D13000 parts are generally listed. But rarely D6600.

Or do they only share with the D13000 up to 1940?

I do not have the books to cross reference the part numbers. Hint hint.

Matt

There are diff parts no. for dif. cyl. parts piston orig 3B9737 then 5B1667 then6B4011 they are just upgrades like ristpin keepers and such but all are interchangable

Cat changes part numbers about as often as the sun comes up but a guy either needs an NPR book or it,s on fische today at the dealer.Lots of later parts & different part numbers do supersede the old numbers but the new parts do work in place of the earlier part numbers.In question the dealer should be able to give you the right info. if you get the parts man that knows whats going on or even the service dept. head (shop foreman) should help.

The cyl parts from any 5E or 2H-RD6 or D6 any 5E or 9G-RD7 or D7 any 5E or 1H-RD8 or D8 and 6600,8800,13000,17000 stationary eng., genset, marine or locomotive engine. Lots of diff parts numbers but all interchangable

Yes, I see lots of part number changes, what if any difference there is would be hard to determine. I think if you keep things in matched sets you'd be ok. I would be a little leary of the liner change. Could be a change in the machining of the block to receive them. Anybody know for sure?

Yes SJ but in this case the actull part is diff, one change is the keepers for ristpin from the plates that held them in to a snap ring, but it fits in same sleeve and uses same pin

thanks for the info! It is a D6-2h s/n 7640. I do have an original parts book for it. My biggest question is how to get the oil pan off. OM pretty well confirmed what I was thinking. remove the spring retainer bracket and jack tractor high enough so pan clears spring. Plan on doing this next week on my next days off. 1 and 2 cylinders look pretty good, just #3 had the water in it. Will replace all 3 liners when I get it apart.
