1D-65 Engine Mechanical:
Honing or reboring cylinders
1) When any cylinder needs reboring, all other
cylinders must also be rebored at the same time.
Oversize piston specification
2) Using micrometer, measure piston diameter.
3) Calculate cylinder bore diameter to be rebored as
follows.
D = A + B – C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 – 0.04 mm (0.0008 –
0.0015 in.)
C: Allowance for honing = 0.02 mm (0.0008 in.)
4) Rebore and hone cylinder to calculated dimension.
NOTE
Before reboring, install lower crankcase and
tighten to specification to avoid distortion of
bearing bores.
5) Measure piston clearance after honing.
Check Valve
Check check valve for clogging and ball for being stuck.
