CAUTION
• When inserting special tool MB992103 into the timing
chain case assembly inside, pay attention to the posi-
tion of the timing chain to avoid damage to the timing
chain and timing chain tension side guide. Do not

• If unlocking the timing chain tensioner is insufficient,
the special tool cannot be inserted to the insertion
guideline. Do not insert the special tool forcibly, follow
Step 1 again to unlock the timing chain tensioner and
insert the special tool.
