Hi All,
anyone know the ideal length dimensions of the bolts to attach the crank spacer and flexplate to the crank? I've gotten the Cummins Part No (3901395) but I want to purchase locally using Grade 10,9 and thought I should consult the Braintrust...

(4BT, CPL 858)

TIA,
Best Regards,
George

if you type cummins and 3901395 into google, and hit search. the first hit will give you a PDF, and then search that and get the measurements.

Thank you Mcinfantry. First time doing that type of search and it worked perfectly.

M12 x 1.25 32

(diagrams only showed flywheel but assume it is the same for a flexplate...)

Best Regards,
George
