Shift fork guide pin grooves
9. The shift drum itself should be in—
spected for wear to the shift fork guide
pin grooves.
10. The shift fork shaft (360 models)
should be inspected for wear in those
areas on which the shift forks ride. Roll
the shaft along a flat surface to check it for
a bent condition. Replace the shaft if
bent.
11. Check the shift forks themselves.
Note any wearto the fork bore. Check the
fingers for bends or for chipping or wear.
Replace any fork on which such defects
are noted.
12. Check the shift fork guide pins for
wear, and replace them if damaged.
13. Check the shift drum dowel pins.
Replace any broken, worn, or missing
pins.
14. Measure the thickness of the shift
fork fingers. If they are smaller than the
service limit for your model, replace
them.
15. Measure the outside diameter of
the shift drum and compare the measured
value to the service limit. Replace as nec—
essary.
16. Measure the inside diameter of the
shift fork and compare the measured
value to the standard value. Replace if
worn beyond the service limit.
17. 360 models: Measure the diameter
of the shift fork shaft. If the measured
Checking shift fork finger width
value is less than the service limit, the
shaft should be replaced.
18. Inspect the guide pin clips and re—
place them if they are distorted or weak.
Installation
1. Slip the shift drum into the upper
crankcase; as the drum enters the case,
