NOTE
Steps 1 through 3 is an alternative repair for the windshield
wiper arm pivot. The repair can be done at commander’s
discretion.
For easy handling, use of an old wiper arm as a hole guide is
recommended. This will also protect the splined surface of the
pivot.
Use roll pin (5315-01-027-4759) for repair.
1. Center punch the side of the wiper arm (1). Position the wiper arm (1) so it is horizontal for drilling
2. Drill a 3/32 in. hole halfway through the center shaft (2). remove the old wiper arm (1), and
continue drilling all the way through the shaft (2) and cap.
3. Using a small hammer or punch drive a roll pin (3) into the hole until it is flush with the surface.
Replace the original wiper arm.
Remove nut (4), washer (5), seal (6), and pivot (8) from windshield frame (7).
