#
Do not attempt to disassemble the camshaft/auto-
matic decompression assembly. It is not serviceable.
CAM WEAR
Worn-down cams are often the cause of mistimed valve opera-
tion resulting in reduced output power.
The limit of cam wear is specified for both intake and exhaust
cams in terms of cam height H, which is to be measured with a
micrometer.
Replace camshaft if found worn down to the limit.
& Cam height H:
Service Limit (IN) : 36.030 mm (1.4185 in)
(EX) : 35.000 mm (13.780 in)
% 09900-20202: Micrometer (25 – 50 mm)
CAMSHAFT JOURNAL WEAR
Determine whether or not each journal is worn down to the limit
by measuring the oil clearance with the camshaft installed in
place.
Use the plastigauge A to read the clearance at the widest por-
tion, which is specified as follows:
& Camshaft journal oil clearance:
Service Limit (IN & EX): 0.150 mm (0.0059 in)
% 09900-22301: Plastigauge
09900-22302: Plastigauge
NOTE:
Install camshaft journal holders to their original positions.
• Tighten the camshaft journal holder bolts evenly and diago-
nally to the specified torque.
