If the thrust clearance is exceed the standard, adjust the
thrust clearance by the following procedures:
• Remove the shim, and measure its thickness with a
micrometer.
Special tool
(A): 09900–20205 (Micrometer (0 – 25 mm))

Cylinder Inspection

Refer to "Engine Top Side Disassembly (Page 1D-17)".
Refer to "Engine Top Side Assembly (Page 1D-21)".
Cylinder Distortion
Check the gasket surface of the cylinder for distortion.
Use a straightedge and thickness gauge. Take clearance
readings at several places. If any reading exceeds the
service limit, replace the cylinder.
Special tool
: 09900–20803 (Thickness gauge)
