Install Camshaft
1. Liberally apply camshaft lubricant to each cam lobe.
Lubricate camshaft bearing surfaces of crankcase
and camshaft with engine oil.
2. Position timing mark of crankshaft gear at 12 o’clock
position.
3. Slide camshaft into bearing surface of crankcase,
positioning timing mark of camshaft gear at 6 o’clock
position. Make sure camshaft gear and crankshaft
gear mesh, with both timing marks aligned.
Determining Camshaft End Play
1. Place a new closure plate gasket into position on
crankcase.
2. Position camshaft end play checking tool over
camshaft. Use a feeler gauge to check end play

Camshaft endplay should be between 0.3/1.3 mm
(0.011/0.051 in.).
3. No shim is typically used from factory. However, if
camshaft end play is not within specifi ed range,
remove checking tool and shim as necessary.
