CAMSHAFTCAMHEIGHT

1. Measure camshaft camheight.

Cam height: Standard
Using micrometer

1. Measure theinner diameter ofcamshaft bearings.

Standard innerdiameter:
30.000 -30.021 mm(1.1811 -1.1819 in)
Tighten bracketboltstothe specified torque.

2. Measure theouter diameter ofcamshaft journals.

Standard outerdiameter:
29.935 -29.955 mm(1.1785 -1.1793 in)

If clearance exceedsthelimit, replace camshaft and/orcylinder
head.
Standard clearance:
0.045 -0.086 mm(0.0018 -0.0034 in)
Limit: 0.1mm (0.004 in)

CAMSHAFT RUNOUT

1. Measure camshaft runoutatthe center journal.

Runout (Totalindicator reading):
Limit 0.05mm(0.0020 in)

2. Ifitexceeds thelimit, replace camshaft.

CAMSHAFT JOURNALCLEARANCE
Using plastigage

1. Wipe offoilfrom camshaft journalbracket capsandbrack-
ets.
2. Install camshaft injournal bracket capsandputplastigage
on each camshaft journal.
3. Install cambracket capsandtighten cambracket capnuts
in the correct ordertothe specified torque.
