McCargar Posted July 22, 2018 Share Posted July 22, 2018 Does anyone have the specifications for the crankshaft and rods for a 1927 standard? Took a rod bearing out the other day, so I’m preparing to re-babbitt and want to know the starting values. Any help will be greatly appreciated.

You don't really have to know standard, if the crank mains were all the same size, when new, grind all to the smallest ones, unless the crank is a stepped crank, like Chevys are where all mains are a different size, with the largest in the rear, and the smallest in the front. You don't have to grind a shaft to a .010, .020, .030, ect . If a crank will clean up, at say .011, or .023 under, why waste, all the extra metal. The mains have to be Align Bored, and the Rods still have to be cut, and the chance anyway is small to find ones that would fit, to replace them down the road, with standard under sizes. 95% of the bearings are done that way, the ones we do, unless the Owner wants the standard under sizes.
