Valve Clearance Adjustment


NOTE

Mark and record the locations of the valve lifters and shims so that they can be reinstalled in their original positions.

Valve Clearance Adjustment


a + b – c = d

[a] Present Shim Thickness

[b] Measured Valve Clearance

[c] Specified Valve Clearance (Mean Value = 0.195 mm (Exhaust), 0.185 mm (Intake))

[d] Replace Shim Thickness

Example (Exhaust): 1.600 + 0.28 – 0.195 = 1.685 mm

Exchange the shim for the 1.675 size shim.

NOTICE

Be sure to remeasure the clearance after selecting a shim. The clearance can be out of the specified range because of the shim tolerance.

If there is no valve clearance, use a shim that is a few sizes smaller, and remeasure the valve clearance.

NOTICE

Do not put shim stock under the shim. This may cause the shim to pop out at high rpm, causing extensive engine damage.

Do not grind the shim. Thismay cause it to fracture, causing extensive engine damage.

Sprocket Wear Inspection
Visually inspect the engine and rear sprocket teeth for wear and damage. If the teeth are worn as illustrated, replace the sprocket, and inspect the drive chain wear (see Drive Chain Wear Inspection in the Periodic Maintenance chapter). Worn Tooth (Engine Sprocket) [A] Worn Tooth (Rear ...

Hub Bearing Inspection
Since the hub bearings are made to extremely close tolerances, the clearance can not normally be measured. NOTE Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones. Turn each bearing in the hub back and forth [A] while checki ...
