Timing Chain: Adjustments

TIMING CHAIN





CAUTION: IT IS ESSENTIAL that the installation procedure is followed exactly. Failure to do so will result in severe engine damage.

CAUTION: Cover timing case recesses to prevent foreign material from entering engine.

1. Use a small screwdriver to prevent the timing chain from slipping down into the engine.




CAUTION: Always install the new timing chain with the oil holes pointing up. Failure to do so will result in severe engine damage.

2. Connect new timing chain, oil hole side up and old timing chain with the assembly link.




3. Place the baking plate on the back side of the master link.




4. Place the master link clip on the master link.




NOTE: Always keep new timing chain meshed with camshaft sprocket.

CAUTION: DO NOT CRANK ENGINE and DO NOT ROTATE ENGINE BACKWARD. Engine rotation is clockwise, as you are looking at the engine. Rotate engine at crankshaft only.

NOTE: With the timing cover and special tools in place, the timing chain can not jump time while being fed through the engine. As the engine is rotated the timing chain may appear to slip as the valve springs move the camshafts.





NOTE: Draw out the end of old timing chain evenly as it becomes free, to the same extent that new timing chain is drawn in.

5. Draw in new timing chain with the oil holes facing up, by rotating the crankshaft slowly in direction of rotation of engine.
6. Rotate the engine until the ends of the new timing chain meet and can be connected.

NOTE: Assembly link is only an assembly aid and NOT designed for engine running.

7. Remove assembly locking element, assembly outer plate and assembly link.
8. Insert new riveted link with the oil hole up, and new middle plate into ends of timing chain using the guide link to hold the middle plate in position.




NOTE: When assembling riveting tool, piece #9312-7 is secured by a screw and #9312-10 can move loosely on thrust spindle

9. Assemble riveting tool by inserting pieces #9312-7 and #9312-10.




NOTE: Ensure that the riveted link and riveting tool are aligned.

10. Press in new riveted link as far as the stop.




11. Remove guide link and riveting tool to change inserts.
12. Install insert 9312-8a on riveting tool.
