Crank Specs
« on: November 11, 2019, 02:40:13 »
Can anyone tell me what the specs are for a 280 crank?
The machine shop doesn't have the specs but says my main is 2.505 and my rods are 2.0315 and I need to figure out which bearing to order.


thanks!

hi John, probably a typo but, the main and rod journal diameters provided by the machine shop appear to be larger than standard. 
Standard diameter (inches) for the mains without regrind is 2.3604 - 2.3608, and the rods 1.8879 - 1.8883. 

See page 5-267 of the attached. vr, Charles
