2. Checking 
(1) Check if the camshaft bearing bush is 
damaged or not (Figure 55). Please 
check the cylinder cover and cylinder 
cover oil hole if any.  
(2) Check if the camshaft and bearing 
surfaces suffer any abnormal wear and 
damage and replace the camshaft if any.  
(3) Check if the camshaft bearing cover 
suffers any wear and damage.  
Note: the replacement of camshaft is 
determined by the abrasion of the 
camshaft. It is allowed to replace the 
rocker arm shaft.  
(4) Measure the actual abrasion of the 
cam nose (Figure 55) or replace the 
camshaft.  
1-Not worn out 
2-Actual abrasion 
3-Bearing bush 
4-Cam 
5-Place subject to abrasion 
3. Fixing 
(1) Lubricate the camshaft bush with 
clean engine oil. 
(2) Fix the camshaft sprocket wheel and 
lock it with a positioning pin.  
(3) Fix the correct camshaft bearing 
cover (Figure38).  
(4) Lubricate the rocker arm with clean 
engine oil.  
(5) Fix the rocker arm shaft and rocker 
arm assembly onto the camshaft.  
(6) Manually fix the rocker arm 
shaft/camshaft bearing onto the cylinder 
cover.  
Note: please check if the camshaft is 
correctly positioned when screwing 
tight the rocker arm shaft/camshaft 
bearing cover.  
(8) Screw tight the rocker arm 
shaft/camshaft bearing cover bolts in 
sequence (Figure 56) with a torque of 
25N.m.
