BASIC BLOCK
CAUTION
Incomplete cleaning will result in piston seizure
or rapid wear of cylinder bores, pistons and
rings. Only thorough rotary brushing with a
strong
detergent
and
water
solution
satisfactorily removes abrasive particles.
4.
Thoroughly clean the cylinder block in an
agitator-type cleaning tank. This type of cleaning
should follow the brushing of the cylinder bores
but is not sufficient by itself for cleaning.
5.
Coat all machined surfaces immediatley after
cleaning with engine oil (SAE 30). Keep the
block covered to exclude dirt until assembled.
