REASSEMBLY
1. Camshaft
1) Before reassembling the camshaft to the
camshaft carrier, align the holes between the
main gear and the sub gear on the intake side of
the camshaft gear with a special tool.
2) Set lock pin to gear holes from sub gear side.
Camshaft Gear Tool: 5-8840-2591-0
Legend
(1) Locking pin
(2) Special tool
3) Apply engine oil to the camshaft gear tooth.
4) Apply engine oil to the journal on the camshaft
carrier.
5) Align the timing mark on the intake and exhaust
camshaft gear and put on the camshaft carrier.

INSPECTION AND REPAIR
Make the necessary adjustments, repairs, and part
replacements if excessive wear or damage is
discovered during inspection.
1. Camshaft Journal diameter
1) Use a micrometer to measure each camshaft
journal diameter in two directions (1) and (2). If
the measured value is less than the specified
limit, the camshaft must be replaced.
Standard: 29.939 – 29.96 mm (1.1787 – 1.1795 in)
Limit: 29.84 mm (1.17 in)
2. Cam Height
1) Measure the cam height (H) with a micrometer.
If the measured value is less than the specified
limit, the camshaft must be replaced.
Standard: IN
46.62 mm (1.8354 in)
EX 46.72 mm (1.8394 in)
Limit: IN
46.57 mm (1.8335 in)
EX 46.67 mm (1.8374 in)
3. Cam Run-Out
1) Mount the camshaft on V-blocks.
2) Measure the cam height (H) with a micrometer.
If the measured value is less than the specified
limit, the camshaft must be replaced.
Standard: 0.02 mm (0.0008 in) or less
Limit: 0.10 mm (0.0039 in)
4. Camshaft oil clearance
1) Clean the camshaft, camshaft bracket and
camshaft carrier.
2) Put camshaft carrier on the cylinder head.
3) Put camshaft on the camshaft carrier.
4) Put plastigauge on the camshaft journal.
5) Install camshaft bracket to original position and
tighten bolts to specified torque in the numerical
order shown in the illustration.
Torque: A; 22 N·m (2.2 kg·m/15.9 lb ft)
B; 38 N·m (3.9 kg·m/28.2 lb ft)
C; 22 N·m (2.2 kg·m/15.9 lb ft)
D; 38 N·m (3.9 kg·m/28.2 lb ft)
