Andrew as far as I know all of the 1H, 2H, and 9G engines were all the same with 50 under being available. Don't if any standard or undersize are available now. The journals on the number series precedeing these were smaller.
Hi Andrew,
as Dick says.
All my Lit. indicates that Std. B/E is 3.6240-3.6250" and the Mains Std. are 3.7490-3.7500" from D7 to early D7E, by my Federal Mogul chart some in between D7E's had 4.25" mains , seems later ones went back to the old dimension? Anyway your query is for D8800 so it is as given above for later engines.
Attached is part of the Federal mogul chart for 4cyl. 5 3/4" bore 4cyl. that I got from Head Hunters some time back.
Line 5B covers D7 from 3T,4T,6T,&7M.
Line 6A covers all RD7.
Note that 10-20-25-50 U/S were available from F/M.
Also note the crankshaft forging No's in this chart.
Also attached from a Cat chart are dimensions for earlier smaller shafts with S/No cut offs.
I put the extra in for future referance by others.
Cheers,
Eddie B.
