INSPECTION
1. CAMSHAFT
a. Measure the bend, and repair or replace if necessary.
Limit: 0.025 mm (0.0010 inch)
b. Check the journal for damage and wear. Replace if faulty.
c. Measure the outside diameter of camshaft journal and inside diameter of cylinder head journal, and determine the difference between the two (= oil clearance). If the oil clearance exceeds specifications, replace the camshaft or cylinder head as necessary.
d. Check the cam face condition; remove the minor faults by grinding with oil stone. Measure the cam height H; replace if the limit has been exceeded.
Cam height: H
Cam base circle diameter A:
IN. 34.00 mm (1.3386 inch)
EX. 34.00 mm (1.3386 inch)
2. CAMSHAFT SUPPORT
Measure the thrust clearance of camshaft with dial gauge. If the clearance exceeds the limit, replace the camshaft support.
Standard: 0.030 - 0.090 mm (0.0012 - 0.0035 inch)
Limit: 0.10 mm (0.0039 inch)
