TM 5-3825-226-24
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 immediately after
cleaning with engine oil (SAE 30). Keep the
block covered to exclude dirt until assembled.
