The initial installation or mounting of a PULLMASTER planetary winch is critically important for proper operation
and performance. If the winch is mounted to an uneven surface, the centre line of the unit can be distorted to a point
where the winch will not operate in either direction. It is therefore very important that the following instructions are
observed when a PULLMASTER planetary winch is installed:
1)
Make certain that the mounting platform is sufficiently strong in order to avoid deflection when a load is lifted.
2)
Set the winch on the mounting platform and check for surface contact on all mounting pads of the winch.
3)
If there is a space between the mounting surface and one of the mounting pads, the mounting surface is not
even and the space below the mounting pad must be shimmed. If this condition exists, proceed as follows:
a)
Install mounting bolts snug tight on the three mounting pads which are in contact with the mounting surface.
(For mounting bolt size and grade see INSTALLATION DRAWING.)
b)
Measure the space underneath the fourth mounting pad with a feeler gauge and use shim stock of equivalent
thickness in the space between the mounting pad and the mounting surface.
c)
Only after this procedure should the fourth mounting bolt be installed. Tighten all four bolts per BOLT
TORQUE CHART.
4)
Fill the winch with lubricating oil. (See APPENDIX A for oil volume required.)
5)
Use recommended circuit components and hydraulic hoses.
6)
The circulation return line of the winch should be plumbed in such a manner that the brake housing remains
full of oil at all times. Connect the return line directly to reservoir. Do not connect to a common return line.
7)
Verify that breather relief, item 130, is in place on end cover above oil level. End cover may need to be rotated
if winch is not installed upright.
IMPORTANT:
Do not replace breather relief or safety valve with a pipe plug. The breather relief does
not prevent oil seal failure but serves as an indicator or warning that the oil seals
between brake housing and the cable drum interior have failed and must be replaced
immediately. The safety valve acts as a warning that excessive pressure is present
in the brake housing and must be rectified immediately.
