from across the bottom edge of the cover(s) being removed.

cover). Remove the cover(s).
Caution:
If both covers were removed in step 7, replace the column mounting bolts after the covers have
been removed. If the column mounting bolts are not replaced the column will be unsupported and
may fall off of it's mount.

(if necessary). Set the original or replacement cover(s) in place on the cycle's frame.
10. Replace and hand tighten the column mounting bolts.
11. Hand start all of the fasteners across the top surface and bottom edge(s) of the cover(s).
Tighten all of the cover fasteners and column bolts in the following order: the three screws
across the top of the cover, the two screws on the rear of the cover, the two screws on the
bottom of the cover and the column mounting bolts last.
12. If the left hand cover has been removed, align the flat surfaces of the crankarm with the flat
surfaces of the axle and slide the crankarm onto the axle. Ensure that the crankarms are
opposite (180°) each other. Place blue loctite on the crankarm mounting bolt and thread the
crankarm mounting bolt into the axle and torque the crankarm bolt to 500 in. lbs. Press the
crankarm cap into place in the crankarm(s).
13. Operate the cycle a high resistance setting until you are assured that the crankarms are
securely mounted.
14. Remove four screws from the and left side of the top cover.
Note
It is not necessary to remove the crankarms to remove the covers on the C842 and C846 version
2 units.
15. Remove two screws from the rear of the cover and two screws from the bottom of the left
and right covers. Remove the left and right cover. Grasp the top cover and move it sideways
away from the front column. Slide the top cover forward and off.
16. When maintenance procedures are complete, set the top cover in place. Gently spread the
the two projecting legs at the rear of the cover and slide the legs under the seat rail. Take
care that you do not snag the lower PCA wiring with the top cover legs.
17. Hand start the two front bolts third from the front top cover mounting bolts on both sides of
the cover. Only start them a few threads, just enough so that they are securely in place.
18. Slide the top edge of the right side cover under the top cover and hand start the two
