INSPECTION
1. CAMSHAFT
a) Measure the bend, and repair or replace if necessary.
Limit: 0.025 mm (0.0010 inch)
b) Check journal for damage and wear. Replace if faulty.
c) Measure outside diameter of camshaft journal and inside diameter of cylinder head journal, and determine the difference between the two (= oil clearance). If oil clearance exceeds specifications, replace camshaft or cylinder head as necessary.
d) Check cam face condition; remove 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 camshaft support.
Standard: 0.030 - 0.090 mm (0.0012 - 0.0035 inch)
Limit: 0.10 mm (0.0039 inch)
