Serial # information

Your tractor would have a D318 engine & you don,t need to pull either the trans. or engine as it will come out without going to all that work. Are you just doing an in frame overhaul of the diesel? If a major rebuild is done then it would have to be removed & then the clutch could be done out of the tractor but the coupling will have to be removed between the clutch & tranny.If just liners and main bearings & pistons & head are to be removed then the belly pan & oil pan can be removed to just go that far which probably is all you,ll need anyway so the engine won,t have to be removed.If mains aren,t removed then the rods can be removed by just going through the side covers of the block which I have on dozens of D4 & D6s and other tractors & engines.

I am planning just to do an inframe. Liners, pistions, rods and mains. Where would you recommend getting parts? What do I need to remove to get to the clutch? Also, do you know about what year this machine would be? Thanks a lot.

I don,t have a year of machines when they were made but only starting production which is 1947 but yours probably was made in the earlier 1950s or middle. There is a top cover on the clutch area to remove it & there is the clutch but the floor boards need removed first. As for parts you have a couple choices either go to Cat or there are after market parts available so maybe someone on here can direct you to a good source. Also I forgot to menton the rear main bearing cap has a cord packing drove up in along each side of it so it must be installed after the cap is up & torqued down & the Cat # is 2B2414.I have put probably a 100 of them in and I always cut about a 6" piece at a time & drove it up in tight with a narrow punch till you get it filled completely.I would keep folding it back and forth up in the hole till it was full & drive each piece up tight as you go.

Thanks for the info.

Sodbuster & SJ,

The D6 was built in 1952 according to the club Serial Number Reference book.
