Paccar CARCO 50B, Manual

PREVENTIVE MAINTENANCE & SPECIFICATIONS

A regular program of preventive maintenance for your
CARCO winch will minimize the need for emergency
servicing and promote long product life and trouble-free
service.

The service intervals suggested in this manual will opti-
mize component service life. The intervals may be grad-
ually increased or decreased with experience of a par-
ticular lubricant and evaluation of your application.

1.

OIL LEVEL

Check the oil level at the beginning of each work shift,
with the tractor and winch in a level position. The oil
must be visible in the upper half of the sight gauge
located on the RH side of the winch. If an oil level plug
is used in place of the sight gauge, the oil level should
be at the bottom of oil level port. Add oil as required
through the fill port on the top LH side of the winch case.

2.

OIL CHANGE, FILTER AND STRAINER
SERVICE

Under normal operating conditions, the oil and pressure
circuit filter should be changed, and the suction strainer
cleaned after the first 100-250 hours of operation.
Follow-up oil and filter changes should occur after every
1000 hours or 6 months of operation, whichever occurs
first, or when the filter bypass light remains on after ini-
tial warm-up.

To drain the oil, place the tractor and winch in a level
position and remove the drain plug located on the lower
RH side of the winch case. Drain the oil into a suitable
container and recycle or dispose of used oil in an envi-
ronmentally responsible manner. Install the drain plug
securely after all oil has been drained. Next, remove the
suction strainer cover, compression spring and seal
rings. Remove the suction strainer from the winch case,
then remove the metal band and magnetic rods from
the strainer. Thoroughly wash the strainer in clean sol-
vent and blow dry with compressed air or clean shop air.
Inspect the wire mesh for damage or clogging with
debris. Do NOT reuse a damaged suction strainer. 

Discharge the accumulator oil supply BEFORE
removing any hydraulic lines or servicing the winch.
Personal injury may result from the sudden release of
oil under pressure. To discharge the accumulator, shut
the engine off, then slowly cycle the control lever into
full Reel-In and Reel-Out positions a minimum of five
(5) times. The tractor master switch and ignition must
be ON.

CAUTION

Hot oil may cause severe injury. Make certain the oil
has cooled to safe temperature (less than 110°F or
43°C) before servicing.
