Timing Chain
REMOVAL TIMING CHAIN1. Remove cylinder head cover.
NOTE: Cover the timing chain area. Care must be taken not to drop any repair debris or pieces into the engine when separating the timing chain links.
2. Install special tool # 9525 using two of the cylinder head cover bolts (Fig. 76).
3. Assemble special tool #93121 using 93123 and 93124. Install insert #931213 and retain with screw provided. (Fig. 77).
CAUTION: Care must be taken not to drop the timing chain plates into the engine once the timing chain is separated.
NOTE: When installing special tool #93121 onto timing chain link, be sure to back off the smaller nut of the thrust pin #93123 until the pin is recessed inside of the spindle, #9312 my. Screw the thrust spindle #9312-4 in until it is seated and aligned properly over the rivet of the timing chain.
NOTE: When fitting the thrust spindle, ensure that the thrust pin is positioned at the left timing chain pin of a chain link.
4. Install special tool #9312 onto timing chain link (Fig. 77).
NOTE: Cover the timing chain area. Care must be taken not to drop any repair debris or pieces into the engine when separating the timing chain links.
5. Carefully turn the thrust pin #93123 of special tool #93121 clockwise while holding the handle until the rivet is pressed out and the chain is separated (Fig. 78). Discard the loose link and plates.
NOTE: One whole timing chain link must be removed.
NOTE: Care must be taken not to drop any repair debris or pieces into the engine when separating the timing chain links.
6. Connect new timing chain with the oil holes facing up, and old timing chain with the assembly link, assembly plate and locking element, and secure (Fig. 79).
CAUTION: IT IS ESSENTIAL that the installation procedure for the timing chain is followed exactly. Failure to do so will result in severe engine damage.
