Six. Fixing the camshaft sprocket 
wheel 
(1) Align with the timing sporcket wheel 
mark and fix the timing chain onto the 
camshaft sprokect wheel.  
(2) Screw on the camshaft sprocket 
wheel bolts with a torque of 115N.m.  
(3) Reset the timing chain tensioner.  
(a) Take out the engine oil chamber from 
the timing chain tensioner (Figure 25).  
(b) Place the timing chain onto an even 
surface.  
(c) Manually press the tensioner as the 
figure shows (Figure 26).  
(4) Fix the engine oil chamber onto the 
timing chain tensioner (Figure 25).  
(5) Fix the timing chain tensioner with a 
torque of 62N.m (46ft.lbs).

(6) Pry off the right timing chain with a 
screw driver (Figure 23). 
(7) Fix the valve chamber cover (see 9-
Engine/cylinder cover/valve chamber 
cover – fixing). 
(8) Fix the camshaft position sensor with 
a torque of 10N.m.  
(9) Connect the storage battery cathode.  
 
 
 
 
 
 
Seven. Timing sprocket wheel and 
guide board 
1. Fixing 
(1) Fix the left timing chain guide board 
with a screwing torque of 28N.m 
(250in.lbs) (Figure 19). 
(2) Fix the right timing chain guide 
board with a screwing torque of 28N.m 
(Figure 24). 
(3) Unfix the valve chamber cover to 
allow the timing chain to move freely.  
(4) Fix the timing chain crank shaft 
sproket wheel and align it with the 
timing mark (Figure 24).
