Using inside micrometer, measure inner diameter “A” of cam-
shaft bracket.
Calculation of Camshaft Journal Oil Clearance
(Journal oil clearance) = (inner diameter of camshaft bracket) – (outer diameter of camshaft journal).
If it exceeds the limit, replace either or both camshaft and cylinder head.
NOTE:
Camshaft brackets cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
Install dial indicator in thrust direction on front end of camshaft.
Measure end play of dial indicator when camshaft is moved for-
ward/backward (in direction to axis).
Measure the following parts if out of the limit.
Dimension “A” for camshaft No. 1 journal
Dimension “B” for cylinder head No. 1 journal
Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and No. 4 journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft sprocket) because it has a different diameter
from the other three locations.
Standard inner diameter:
No. 1 : 26.000 - 26.021 mm (1.0236 - 1.0244 in)
No. 2, 3, 4 : 23.500 - 23.521 mm (0.9252 - 0.9260 in)
