Kawasaki KLE500 (2004) [130/401] Camshaft journal camshaft cap clearance

5-18 ENGINE TOP END

Camshaft, Camshaft Chain

Camshaft, Camshaft Cap Wear

The journal wear is measured using plastigage (press

gauge), which is inserted into the clearance to be mea-

sured. The plastigage indicates the clearance by the

amount it is compressed and widened when the parts are

assembled.

•

Cut strips of plastigage to journal width. Place a strip on

each journal parallel to the camshaft with the camshaft in-

stalled in the correct position and so that the plastigage

will be compressed between the journal and camshaft

cap.

•

Install the camshaft caps, tightening the bolts in the cor-

rect sequence.

Torque - Camshaft Cap Bolts: 12 N·m (1.2 kgf·m, 8.5 ft·lb)

NOTE

○

Do not turn the camshaft when the plastigage is be-

tween the journal and camshaft cap.

•

Remove the c amshaft caps again, and measure the plas-

tigage width [A] to determine the clearance between each

journal and camshaft cap. Measure the widest portion of

the plastigage.

Plastigage Scale [B]

If any clearance exceeds the service limit, measure the

camshaft journal diameter and the camshaft bearing in-

side diameter.

If any of the measurements is beyond the service limit,

replace the worn part and check the clearance again.

Camshaft Journal, Camshaft Cap Clearance

Standard: 0.030 ∼ 0.071 mm (0.0012 ∼ 0.0028 in.)

Service Limit: 0.16 mm (0.006 in.)

Camshaft Chain Guide Wear

•

Visually inspect the rubber [A] on the guides.

If the rubber is damaged or cut, replace the guides.
