Measure outer diameter of camshaft journal. Standard outer diameter:
No.1: 25.935 - 25.955 mm (1.0211 - 1.0218 inch)
No. 2, 3, 4: 23.445 - 23.465 mm (0.9230 - 0.9238 inch)
Inner Diameter of Camshaft Bracket
^
Tighten camshaft bracket bolt with specified torque.
^
Using inside micrometer, measure inner diameter "A" of camshaft bracket.
Standard inner diameter:
No.1: 26.000 - 26.021 mm (1.0236 - 1.0244 inch)
No. 2, 3, 4: 23.500 - 23.521 mm (0.9252 - 0.9260 inch)
Calculation of Camshaft Journal Clearance
(Journal clearance) = (inner diameter of camshaft bracket) - (outer diameter of camshaft journal).
Standard:
No.1: 0.045 - 0.086 mm (0.0018 - 0.0034 inch)
No. 2, 3, 4: 0.035 - 0.076 mm (0.0014 - 0.0030 inch)
Limit: 0.15 mm (0.0059 inch)
When out of the limit, replace either or both camshaft and cylinder head.
NOTICE: Inner diameter of camshaft bracket is manufactured together with cylinder head. Replace the whole cylinder head assembly.
Camshaft End Play
^
Install dial gauge in thrust direction on front end of camshaft. Measure end play of dial gauge when camshaft is moved forward/backward (in
direction to axis).
Standard: 0.115 - 0.188 mm (0.0045 - 0.0074 inch)
Limit: 0.24 mm (0.0094 inch)
^
When out of the limit, replace with new camshaft and measure again.
^
When out of the limit again, replace with new cylinder head.
Camshaft Sprocket Runout
^
Put V block on precise flat bed, and support No. 2 and No.4 journal of camshaft.
