Will a D6600 (RD6) crankshaft fit a D6100 (D35), unfortunately I don't have any parts books to compare numbers etc. Many thanks for any help.

Info I have says the original D35 (D6100) crankshaft part number is 1B9830
The original RD6 (D6600) crankshaft part number is 2B4860
Both have the same Service Part Number 7B2953 with 3-1/4" rod journals and 3-1/2" main journals.
So yes it appears they interchange but I can not guarantee that it works myself.
