TWO-SPEED MOTOR CASE DRAIN PLUMBING
Some hoists with two speed gear motors may have been in-
stalled with the motor case drain connected to the drain port
of the brake valve. Th is system may result in accelerated mo-
tor sha ft seal wear and leakage. Th e following modi fi cation
should be made to the motor hydraulic piping to prevent this
type of seal damage.
1. Remove the motor case drain hose from the
brake valve drain port and install plug, Item 1,
into the valve port. Remove the hose from the
case drain port elbow, Item 4.
2. Install a new case drain hose, Item 2, onto
the motor case drain elbow, Item 4.
3. Install the tee adapter, Item 3, into the two-
speed motor shi ft valve drain port (identi fi ed
by long end cap).
4. Install the new motor case drain hose, Item
2, onto the tee adapter.
5. Install a case drain hose for the tee directly
to the reservoir. Minimum hose size is –6,
3/8 in. (9.5 mm). Maximum drain line back
pressure is 100 PSI (690 kPa) measured at the
motor case drain port.

PREVENTIVE MAINTENANCE
A regular program of preventive maintenance for your planetary hoist is strongly recommended to minimize the need for
emergency servicing and promote safe, reliable hoist operation.
Field experience, supported by engineering tests, indicate the three (3) service procedures listed below are the MOST critical
to safe, reliable hoist operation and must be observed.
• Regular Gear Oil Changes – every 1000 hours or six (6) months
• Use of Proper Gear Oil – recommended type for prevailing ambient temperature
• Periodic disassembly and inspection of all wear items.
1.
OIL LEVEL
Th e gear oil level should be checked every 500 operating
hours or three (3) months, whichever occurs fi rst. To check
the oil level, remove the large plug located in the center of
the drum support. Th e oil should be level with the bottom
of this opening or approximately half-way up in a sight glass.
This is extremely important due to the accelerated
