8. Use a white pen to accent the timing marks on the following
gears: camshaft gear (K), crankshaft gear (M), or
counterbalance gear (N) This will ensure proper gear
alignment and timing during reassembly of the gears.
NOTE: If replacing one of the gears, it is
recommended that all of the gears be replaced. A
gear kit is available.
9. Use the Cam Gear Tooth Alignment Tool (PU-45497-2) to
align and hold the cam split gear assembly. With the split
gear aligned, remove the bolt and cam gear assembly.
NOTE: Install the Cam Gear Tooth Alignment Tool
(PU-45497-2) into the assembly hole counter
clockwise from the timing mark (see page 3.42).
10. Inspect the cam gear teeth and check to make sure there is
spring tension offsetting the teeth between the two gears.
If there is no tension, check the springs inside of the cam
gear assembly.
11. The cam gear assembly contains three loaded springs. To
open the cam gear assembly:
• Place the cam gear on a flat surface with the timing
mark side facing up.
• While holding both gears together, lightly work a small
flathead screwdriver between the two gears.
• Remove the top gear. The springs should stay in place.
12. Remove all three springs using one of the tapered pins from
the Tapered Pins (PU-45497-1).
13. With a white marking pen, accent the timing mark on the
gear that contains the springs.
