TAPPET
1. Inspect the tappets for wear or damage. Replace the tap-
pet if necessary.
2. Measure the tappet outer diameter.
Diameter
mm (in)
HA. SL
14.218-14.233 (0.5598-0.5604)
TF
15.518-15.533 (0.6109-0.6115)
3. Measure the tappet bore diameter of the cylinder block.
Diameter
mm (in)
HA
SL 14.288-14.319 (0.5625-0.5637)
TF
15.588-15.619 (0.6137-0.6149)
4. Subtract the tappet outer diameter from the tappet bore di-
ameter to calculate the tappet to tappet bore clearance.
Clearance
Standard: 0.055-0.101 mm (0.0022-0.0040 in)
Maximum: 0.1Smm (0.006 in)
5. If the clearance exceeds the maximum, replace the tappet
and/or cylinder block.
OIL JET
1. Push the check ball and verify that it moves smoothly.
2. Blow through the oil jet and veri.fy that air flows.
IDLER GEAR
1. Measure the idler gear inner diameter.
Diameter:
44~009-44.034mm
(1.7326-1.7336 in)
2. Measure the idler gear spindle outer diameter.
Diameter: 43.950-43.975mm (1.7303-1.7313 in)
3. Subtract the spindle outer diameter from the idler gear in-
ner diameter to calculate the spindle to idler gear clearance.
Clearance
Standard: 0.034-0.084mm (0.0013-0.0033 in)
Maximum: 0.1Smm (0.006 in)
4. If the clearance exceeds the maximum, replace the idler
gear and/or spindle.
