REPAIR AND REPLACEMENT OF PARTS CYLINDER BLOCK
GRINDING CRANKSHAFT
★ When grinding the crankshaft to correct wear, light seizure or damage, grind to an undersize.
★ If there is curvature of the crankshaft, it is preferable to replace the crankshaft and not to grind it to an undersize. (There are problems with balancing.)
★ Do not try to correct a bent crankshaft with a press. When the engine is run, the crankshaft will gradually return to its bent shape.
★ The journal portion has been given induction hardening, so do not try to repair it by bead welding or plating.
★ Unevenly worn crankshafts will bend or be unbalanced even if repaired, so always replace unevenly worn crankshafts.
★ Measure the part for grinding to decide the undersize dimension.
★ Judge from the measured dimension, and if the undersize dimension will exceed the repair limit, replace the crankshaft.
★ When repairing the plating of the damaged surface, repair only the following places.
1) Rear seal journal portion
2) Crankshaft gear mount
★ When correcting damage to the crankshaft, pay particular attention when finishing the R portion of the fillet and shoulder r (see the diagram on the right) and the R at the inlet port of the oil hole.
