HOPPER SYSTEM

HOPPER LIFT CYLINDER REMOVAL

Note: To remove the cylinder it is necessary for the hopper to be in the raised position.  If the cylinder will not raise under its own power it will be
necessary to press and hold the hopper raise switch with the key switch on and raise the hopper with an overhead hoist or some other alternate
method.  The reason the hopper switch needs to be activated is to turn on the hydraulic solenoid cartridge to allow the cylinder oil to return to tank.

CAUTION!

There will be oil in cylinder and hoses, be prepared to plug hoses and recover cylinder oil.

WARNING!

Use common sense safety practices when performing this repair.

WARNING!

When removing the hopper cylinder do not rely solely on prop rod to support hopper.  Support the hopper with some additional
means such as overhead hoist, stands etc.

To Remove:
1

Raise the hopper and pull the safety prop rod into position then lower hopper until the rod is secure.

2

Turn the engine off and then disconnect the battery.

3

Separate the engine’s ECU module-wiring harness located on the front engine access panel, then remove the engine access door panel.

4

Remove the Retaining Ring (M) from the Rod Pin (N) and completely remove the pin.

5

Remove the Screw (O) that fastens the lower Hinge Pin Weldment (P) to the chassis then pry pin to the side.

6

Pull the hopper cylinder forward and remove the two hydraulic hopper cylinder hoses to complete cylinder removal from machine (mark hoses
for correct installation).

WARNING!

Make sure hopper is securely supported before working under hopper.

To Install:
1

With the hopper securely supported, mount the cylinder piston end to the chassis and pry the pin weldment back into position and secure in
place with previously removed screw.

2

Pull the cylinder rod end out until you are able to align (match up) the cylinder rod clevis to hopper mount (don’t install pin at this time).  Then
reconnect the two cylinder hoses and secure the cylinder rod end to the hopper with its pin and retaining rings.

3

Reinstall the front engine access panel and also reconnect the ECU module wiring harness.  Next reconnect the battery, start engine and raise
hopper to release safety prop rod.  Then run the cylinder up and down several times and check for leaks.
