6. With cam and gear washed and cleaned ready for reassembly, apply press fit lube to cam and gear.
7. Place gear back on cam tool with felt pen mark showing and aligned with pinion reference mark.
Install tapered pins back in the holes they were removed from. (See Diagram E)
8. Gently place the cam into bore of gear. At the same time, turn the cam in a clockwise direction. The cam will drop
down about 1/8". At the same time, all clockwise rotation will stop. NOTE: All clockwise rotation will stop because
the ignition drive notch has mated with locator pin in the bore of the tool and the cam should make contact with the
gear. While holding the cam in this position, place your 3/8" ball bearing into the center at the end of cam. You can
start pressing cam into gear. As soon as the cam's shoulder makes contact with gear, the pressing is complete.
9. As a reference, check to see if large key in cam is 180
gear.
Example of degreeing in a cam:
10. If you decide to alter cam timing, this tool will align the gear to cam within1/4 of a degree. With the tool still locked
in position for the above cam. (For example: Let us say the above cam required the tool to be set at "O" degrees just
like Diagram A). Next example: If you have degreed the above cam and it is indicated that you need to retard by 2
degrees.
Proceed as follows:
11. After reading line 10 reinstall cam assembly in tool to make it easier to adjust. NOTE: Do not install the tapered pins
at this time. Rotate cam assembly clockwise until cam locks into tool (See line 1.). Loosen the two knurled thumbscrews
just enough to retard indexer plate 2 degrees. (Note: Each line lasered on tool base is two degrees).
12. Retighten the two knurled thumbscrews by hand only. (Check side of tool for 2 degrees of retard).
13. Remove gear from cam with JIMS® tool No. 1390.
14. Follow line 6, 7, 8.
15. You can recheck your degreeing of cam, and/or install in motor per H-D® service manual. Follow any additional
instructions supplied by camshaft manufacturer.
CAUTION: Wear safety glasses. Excessive force may damage parts and tool.
