CAMSHAFT JOURNAL WEAR
Determine whether each journal is worn down to the limit or not
by measuring camshaft journal oil clearance with the camshaft
installed. Use plastigauge to read the clearance, which is speci-
fied as follows:
% Camshaft journal oil clearance
Service Limit: 0.150 mm (0.0059 in)
( 09900-22302: Plastigauge
NOTE:
To properly measure the oil clearance with plastigauge, all gas-
ket material must be removed from fitting surfaces of cylinder
head and cover. Do not apply SUZUKI BOND “1216B” until after
the oil clearance has been determined.
• Tighten the cylinder head cover bolts evenly and diagonally to
the specified torque.
# Cylinder head cover bolt
(M6): 10 N·m (1.0 kgf-m, 7.0 lb-ft)
NOTE:
Do not rotate the camshafts with the plastigauge in place.
Remove the cylinder head cover, and read the width of the com-
pressed plastigauge with envelop scale. This measurement
should be taken at the widest part.
If the camshaft journal oil clearance measured exceeds the limit,
measure the outside diameter of camshaft.
Replace either the cylinder head set or the camshaft if the clear-
ance is incorrect.
% Camshaft journal O.D.
Standard (Sprocket side): 21.959 – 21.980 mm
(0.8645 – 0.8654 in)
(Other side) : 17.466 – 17.484 mm
(0.6876 – 0.6883 in)
( 09900-20205: Micrometer (0 – 25 mm)
CAMSHAFT RUNOUT
Measure the runout with a dial gauge. Replace the camshaft if
the runout exceeds the limit.
% Camshaft runout (IN & EX)
Service Limit: 0.10 mm (0.004 in)
( 09900-20607: Dial gauge (1/100, 10 mm)
09900-20701: Magnetic stand
09900-21304: V-block (100 mm)
