CYLINDER H EAD/VALVE H O NDA VT500C Measure the amount of the cam chain tensioner pro jects as shown. Replace the cam chain with a new one if the projection exceeds 9.0 mm (0.35 in).
To replace the cam chain, drain the oil from the engine and remove the following parts:
Pull wedge A straight up while holding wedge B down. Secure wedge A w ith a 2 mm pin as shown.
Remove the cam sprocket bolts. Rotate the crankshaft clockwise one turn (360°) and remove the other cam sprocket bolts.
NOTE
Be careful not to let the cam sprocket bolts fall into the crankcase.
Remove the cam sprocket from the camshaft flange with the cam chain.Rotate the crankshaft clockwise half a turn (180°) and remove the cam chain from the sprocket.
Hang the cam chain on the camshaft behind the camshaft flange. Remove the cam sprocket while lifting the camshaft out.
Attach a piece of wire to the cam chain to prevent it from being dropped into the crankcase. (1) PIN

INSPECTION
CAMSHAFT HOLDER/CY LINDER HEAD
Inspect the camshaf t holder and cylinder head journal surfaces for scoring, scratches, or evidence of insufficient lubrication.
CAMSHAFT RUNOUT
Check camshaft runout with a dial indicator. Support both ends of the camshaft with V-blocks. Use 1/2 of the total indicator reading to determine run ou t. SERVICE LIMIT: 0.05 mm (0.002 in)
CAM LOBE HEI G HT Using a micrometer. measure the heigh t of each cam lobe.
SERVICE LIMITS: IN: 38.00 mm (1.496In) EX : 37.90 mm (1.492 in)
CAMSHAFT INSPECTION Check the camshaft journals for wear or damage. Measu re the 0.0. of each jou rnal.
SERV ICE LIMITS : 21.826 mm (0.859 in)
Wipe any oil from the journals .Lay a strip of plastl · gauge lengthwise on top of each camshaft jou rnal.
NOTE
Avoid placing plastigauge over the oil hole in the cam holder.
Hook the cam chain suspension wi re against the cam chain guide.
NOTE
(1) PLASTIGAUGE
Install the camshaft holder's and tighten in a criss· cross pattern in 2-3 steps.
NOTE
Do not rotate the camshaft when using plati· gauge.
TORQUES: 6 mm bolt/nut: 20-25 N-m (LEFT) (2.0-2.5 kg·m, 14-18ft lb) 6 mm SH bolt: 8-12 N·m (RIGHT) (0.8-1.2 kg·m. 6-9 ft-lb)
Remove the camshaft holders and measure the width of each plastigauge. The widest thickness determines the oilclearance.
SERVICE LIMIT :0.23 mm (0.009 in)
When the service limits are exceeded,replace the camshaft and recheck the oil clearance.
Replace the camshaft holders if the clearance still exceeds the service limits.
