4) Calculate cylinder bore diameter to be rebored.
D = A + B – C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 – 0.04 mm
C: Allowance for honing = 0.02 mm (0.0008 in.)
5) Rebore and hone cylinder to calculated dimension.
NOTE:
Before reboring, install all main bearing caps in place and
tighten to specification to avoid distortion of bearing bores.
6) Measure piston clearance after honing.
INSTALLATION
NOTE:
D All parts to be installed must be perfectly clean.
D Be sure to oil crankshaft journals, journal bearings, thrust
bearings, crankpins, connecting rod bearings, pistons, pis-
ton rings and cylinder bores.
D Journal bearings, bearing caps, connecting rods, rod bear-
ings, rod bearing caps, pistons and piston rings are in com-
bination sets. Do not disturb such combination and make
sure that each part goes back to where it came from, when
installing.
1) Install main bearings to cylinder block (1).
Upper half of bearing (2) has an oil groove (3). Install it to cylinder
block, and the other half without oil groove to bearing cap.
Make sure that two halves are painted in the same color.
2) Install thrust bearings (1) to cylinder block between No.2 and
No.3 cylinders. Face oil groove (2) sides to crank webs.
