Dimension

Use a micrometer to measure the cam lobe height and uneven wear. Replace the camshaft if either the lobe height or the uneven wear exceeds the specified limit.

Lobe height 44.709 mm (1.7602 inch)
Uneven wear 0.05 mm (0.0020 inch)





Use a micrometer to measure the diameter and the uneven wear of the camshaft journals. Replace the camshaft if the diameter or the uneven wear exceeds the specified limit.

Journal Diameter
Standard 25.972 mm - 25.993 mm (1.0225 inch - 1.0233 inch)
Limit 25.8 mm (1.0157 inch)
Uneven wear 0.05 mm (0.0020 inch)





Place the camshaft on V-blocks. Slowly rotate the camshaft and measure the runout with a dial indicator. Replace the camshaft if the runout exceeds the specified limit.

Run out
Limit 0.1 mm (0.0039 inch)





Measure the camshaft journal oil clearance.
Measure the camshaft bracket housing inside diameter.

NOTE: Tighten camshaft bracket (2) to 10 Nm (89 inch lbs) before measuring the camshaft bracket inside diameter.




Subtract the camshaft outside diameter from the camshaft bracket housing inside diameter.

Oil Clearance
Standard 0.027 mm - 0.078 mm (0.0011 inch - 0.0031 inch)
Limit 0.11 mm (0.0043 inch)





Measure the camshaft thrust clearance with a dial indicator. Replace the camshaft and/or the cylinder head if the camshaft thrust clearance exceeds the specified limit.

Camshaft thrust Clearance
Standard 0.03 mm - 0.08 mm (0.0012 inch - 0.0031 inch)
Limit 0.12 mm (0.0047 mm)
