1. Measuring main journals and crankpins
Before grinding the pins, measure the pins of the
shaft (2) with a micrometric gauge (1) and establish,
depending on the level of undersizing of the bear-
ings, to what diameter you need to reduce the pins.
The classes of undersizing are 0.127 -0.254 - 0.508
mm ( 0.0050 - 0.0100 - 0.0200 in).
It is advisable to note down the measurements in a
table Fig.2
NOTE: All the main journals and crankpins should always
be ground to the same class of undersizing so as not to
alter the balance of the crankshaft.
