Removal
1
Place the side brooms in the lowered position if possible or blocking underneath the brooms to remove weight from the lift linkage.
2 Open hopper cover, set cover prop rod, remove hopper filter, and latch filter rack. Then remove the hopper access panel held in-place by
(11) Philips head screws.
3 Disconnect the lift actuator motor wiring harness connector.
4 See Figure 5. Remove the (2) Hex Huts (Y) that secure the Hopper Cylinder Valve Block (Z) to its mount.
5 Pull the valve body block away from its mounted position and then rest it on the corner of the mount (this needs to be done to access the rear
actuator motor mount). Next remove the Hairpin (AA) from its mount pin.
6 Remove both the front Retainer Ring (AB) and the Mount Pin (AC) that attaches the actuator drive tube to the Lifting Shaft Weldment (AD).
Then pull out the lift motor to complete its removal from the machine.
Installation
Service Note: New replacement lift actuator motors do not come with lift drive tube pre-adjusted.
Important: After removing the actuator motor and before replacing a new motor or drive tube the IN & OUT limit switches must be set (or checked)
to their correct installation dimensions. Follow the side broom lift actuator motor adjustment instructions in this manual section if the drive nut (tube)
is in need of adjustment.
1
After setting the correct actuator lift nut dimensions follow the removal steps above in reverse order to re-install.
