Cat engine progression

As near as I can make out from my TRW Engine parts manual the next series 8 cylinder 5-3/4 bore engines would be D364 series 19B, 20B, 21B and the D375 series 16B, 17B, 18B, 43B and that seems to be the end of the 5-3/4 bore 8-cylinder engines. I don't have specific dates but I'd guess these would be 1960's engines.

So that is the end of V8 engines? No newer series? Then everything then V12 and V16?

Not the end of the V8 cylinder, just the 5-3/4" bore versions.

had a dig around in a few books and came up with the following Cat V8 engines;
3208
3408
3508
D379
D346
1160
1150
1145
3150
3145
No doubt there are more than what I have listed here, as well there are many different configurations of those listed.

i hope this helps.

With the little research I have come up with the D17000 was produced between 1935 to 1955. There was a lot of variations with in its life both in the pony motor and the Main engine. The pony went from Timken main bearings to inserts, and the main engine went from six ring pistons to four. The six ring pistons are no longer available that I can find. Older main engine had two water pumps and later had One. Valve covers had a spacer between the head and the valve cover. When I overhauled mine I could still get the Valve cover gaskets ,head gaskets, Liners, rings for the six ring pistons, valves for the pony and main engine. Had to make my own pan gasket. and a lot of other stuff also.
These engines are a beast and have the coolest noise when running.
