Cylinder Block

FLATNESS LIMIT
Cylinder Block Flatness Limit 0.06 mm (0.0024 inch)


NOTE: Using straightedge and thickness gauge, check gasketed surface for distortion and, if flatness exceeds its limit, correct it.











HONING/PISTON CLEARANCE
Using micrometer, measure piston diameter. Calculate cylinder bore diameter to be rebored as follows:

Cylinder bore diameter to be rebored D
Piston diameter as measured A
Piston clearance (B) = 0.02 - 0.04 mm (0.0008 - 0.0015 inch)
Allowance for honing (C) = 0.02 mm (0.0008 inch)

NOTE: D=A+ B-C

NOTE: When any cylinder needs reboring, all other cylinders must also be rebored at the same time. Select oversized piston according to amount of cylinder wear.
