Repairing the Speedometer Drive
Proceed with inspection and repairs, when wear of teeth becomes obvious (the
speedometer fails to operate even when the flexible shaft is intact) or in case of
dismantling the gearbox in general.
When repairing, change worn-out parts, paying attention to ease of rotation of the
gearing and proper backlash in the toothing (with the flexible coupling flange stopped in
any position, the driven gear should display a slight side play in the gearing).
Removing the Gear Shift Mechanism (gearbox removed)
The gearbox is disassembled and assembled at ambient temperature. The gear shift
mechanism consists of the following assembly units and parts: (Fig. 5.1-5 and 5.1-6).
•
