10. INSPECT VALVE LIFTER

(a) Using a micrometer, measure the valve lifter 

diameter.
Valve lifter diameter:

30.966 to 30.976 mm (1.2191 to 1.2195 in.)

11. INSPECT VALVE LIFTER OIL CLEARANCE

(a) Using a caliper gauge, measure the lifter bore 

diameter of the cylinder head.
Lifter bore diameter:

31.009 to 31.025 mm (1.2208 to 1.2215 in.)

(b) Subtract the valve lifter diameter measurement 

(Step 16) from the lifter bore diameter 
measurement.
Standard oil clearance:

0.033 to 0.059 mm (0.0013 to 0.0023 in.)

Maximum oil clearance:

0.08 mm (0.0031 in.)

If the oil clearance is greater than the maximum, 
replace the valve lifter.
If necessary, replace the cylinder head.

REMOVE VALVE GUIDE BUSH
(a) Gradually heat the cylinder head to 80 to 100

°C 

(176 to 212

°F).

(b) Place the cylinder head on a wooden block.
(c) Using SST, tap out the valve guide bush.

INSTALL VALVE GUIDE BUSH
(a) Using a caliper gauge, measure the bush bore 

diameter of the cylinder head.
Bush bore diameter:

10.295 to 10.315 mm (0.4053 to 0.4061 in.)

If the bush bore diameter of the cylinder head is 
greater than 10.315 mm (0.4061 in.), machine the 
bush bore to the dimension of 10.345 to 10.365 mm 
(0.4073 to 0.4081 in.).

(b) Gradually heat the cylinder head to 80 to 100

°C 

(176 to 212

°F).

(c) Place the cylinder head on a wooden block.
(d) Using SST, tap in a new valve guide bush to the 

specified protrusion height.

(e) Using a sharp 5.5 mm reamer, ream the valve guide 

bush to the standard specified clearance between 
the valve guide bush and valve stem.
