NOTE: With the timing chain tensioner unlocked, 
insert the special tool MB992103 along the ten-
sion side of the valve timing chain, according to 
the special tool MB992103 top shape. The special 
tool MB992103 can be inserted smoothly to the 
position where the special tool MB992103 inser-
tion guideline aligns with the timing chain case 
assembly top surface (B in the figure), and the 
spread timing chain tension side guide can be 
hold (C in the figure).

3. With the special tool MB992103 inserted up to the 

insertion guide line, press the special tool 
MB992103 against the inlet side camshaft 
sprocket and spread and hold the timing chain 
tension side guide.

4. Remove the precision flat-tipped screwdriver 

unlocking the timing chain tensioner.

CAUTION

The valve timing chain may be bitten by other 
parts. After sagging the valve timing chain, never 
rotate the crankshaft.
