Engine Mechanical: 1D-60
Cylinder Inspection

Refer to “Engine Top Side Disassembly (Page 1D-28)”.
Refer to “Engine Top Side Assembly (Page 1D-32)”.
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)
Cylinder distortion
Service limit: 0.20 mm (0.008 in)
Cylinder Bore
Measure the cylinder bore diameter at six places. If any
one of the measurements exceed the limit, overhaul the
cylinder and replace the piston with an oversize piston.
The remaining cylinders must also be rebored
accordingly; otherwise, the imbalance might cause
excessive vibration.
Special tool
(A): 09900–20530 (Cylinder gauge set)
Cylinder bore
Standard: 81.000 – 81.015 mm (3.1890 – 3.1896 in)
Piston-to-cylinder Clearance
Refer to “Piston and Piston Ring Inspection (Page 1D-
62)”.
