hole of the timing chain case, press up the timing chain
tensioner ratchet to unlock, and keep the timing chain
tensioner with that state.
NOTE: Lightly press down the tail end of the precision
flat-tipped screwdriver to press up the tip of the precision
flat-tipped screwdriver inserted to the timing chain tensioner
to unlock.
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
insert the special tool MB992103 beyond its insertion
guideline.
• If unlocking the timing chain tensioner is insufficient,
the special tool MB992103 cannot be inserted to the
insertion guideline. Do not insert the special tool
MB992103 forcibly, follow Step 1 again to unlock the
timing chain tensioner and insert the special tool
