DISASSEMBLY
INSPECTION
Cylinder Block
1. Check the cylinder block for scores, rust and corrosion. Also check for cracks or any other defects. Replace
the block if defective.
2. Measure the cylinder bore with a cylinder gauge at the three levels indicated, in the directions A and B.
Level 2: Center of cylinder
3. If the cylinder bores show more than the specified out-of-round or taper, or if the cylidner walls are badly
scuffed or scored, the cylinder block should be rebored and honed. New oversize pistons and rings should be
installed.
Standard value
Cylinder bore : 86.7 mm (3.41 in.)
Out-of-round and taper of cylinder bore :
Max. 0.02 mm (0.0008 in.)
4. If a ridge exists at the top of the cylinder, cut it off with a ridge reamer.
5. Oversize pistons are available in two sizes.
Piston service size and mark mm (in.)
0.25 (0.010) O.S : 0.25
0.50 (0.010) O.S : 0.50
6. To rebore the cylinder bore to the oversize, maintain the specified clearance between the oversize piston and
the bore and make sure that all used pistons are the same oversize. The standard measurement of the piston
outside diameter is taken at a level of 15.5mm (0.61in.) above the bottom ofthe piston skirt and across the
thrust faces.
Piston-to-cylinder clearance
0.01 ~ 0.03mm (0.0004 ~ 0.0012in.)
