6.2.5. Camshaft
1) Cam
Cam lobe height
Use a micrometer to measure the cam
lobe height and journal diameter.
If the measured number is less than
the specified limit, the camshaft must
replaced.
Cam surface
Inspect the cam surface for scratch or damage.
Slight step wear or damage on the cam surface may be corrected with an oilstone or oiled
grinding paper. But, replace if severely damaged.
2) Camshaft
Clearance between camshaft
journal and camshaft bush
- With an outside micrometer,
measure the camshaft journal
diameter.
- Measure the inside diameter of the
camshaft bush on the cylinder block
using a cylinder bore indicator, and
compare the measured value with
the camshaft outside diameter to
determine the clearance.
<Clearance>
Replace the bush if the measured value is beyond the specified limit.
