RT540E SERVICE MANUAL HOIST AND COUNTERWEIGHT
Installation
1. Ensure the mounting plate and hoist pads are clean and
free from debris and the hoist has not been damaged
during handling.
2. With the hoist supported by a suitable lifting device,
position the hoist on the mount.
3. Check the hoist to boom alignment according to the
HOIST TO BOOM ALIGNMENT procedure in this
section.
4. Place a level between the boom pivot shaft bushings.
5. Place a level across the top of the hoist drum and
determine if the hoist is sitting in the same plane in
relation to the level positioned between the boom pivot
shaft bushings.
6. With the hoist level, check to determine if all the hoist
mounting pads are in contact with the mounting plate by
rocking the hoist.
7. Keeping the hoist level, use a feeler gauge to determine
the amount of gap existing between the pads and the
mounting plate.
8. Add shims to satisfy any existing gaps. Altering the shim
thickness to fit a tapering gap is acceptable. Install the
capscrews, washers and nuts and torque see Fasteners
and Torque Values (pg 1-11).
9. Remove the lifting device from the hoist.
10. Connect the hydraulic lines to the hoist ensuring the
proper lines are connected to the correct ports as
marked during removal.

solenoid valve as marked during removal.
12. Connect the electrical wires to the hoist rotation indicator
sensor as tagged during removal.
13. Install the cable, following the procedures outlined under
INSTALLING CABLE ON THE HOIST, in the Operator
Manual.
Functional Check
1. Attach a test weight to the hook and raise and lower the
load several times.
2. Check the hoist for smooth operation of the hoist motor
and brake system.
3. Ensure the hydraulic connections are secure and free
from leaks.

Fill with AGMA EO-4 (Grove Spec 6829100213) gear
lubricant until level with the plug opening. Check every 1000
