Wheel And Deck Zerks; Front Wheel Mount; Front Wheel Bearings; Cables - Husqvarna PZ 72 Owner's Manual

Wheel and Deck Zerks

Use only good quality bearing grease.
Grease from well-known brand names
(petrochemical companies, etc.) usually maintains a
good quality.

Front Wheel Mount

Remove dust cap to expose zerk. Lubricate with a
grease gun until the grease is forced out around the
top washer.

Front Wheel Bearings

Lubricate 3-4 strokes with a grease gun on each set
of wheel bearings.

Cables

If possible, grease both ends of the cables and
move the controls to end stop positions when
lubricating. Refit the rubber covers on the cables
after lubrication. Cables with sheaths will bind if they
are not lubricated regularly. If a cable binds, it can
disrupt operation.
If a cable binds, remove the cable and hang it
vertically. Lubricate it with light engine oil until the oil
begins to escape from the bottom.

Hydraulic Drive

Fluid and Filter Change

the hydraulic drive is designed with an external
filter for ease of maintenance. to ensure
constant fluid quality levels and longer life, an
oil filter change interval of every 500 hours is
recommended.
the following procedure can be performed with the
pump installed in the vehicle, and the vehicle on
level ground.
1. Lock the vehicle parking brake.
2. Place an oil drain pan with a 2 gallon capacity
beneath the oil reservoir. Remove the drain
port and drain oil. Remove the oil filter from
the pump.
Drain old oil filters of all free-flowing
oil prior to disposal. Place used oil in
appropriate containers and dispose of it in
accordance with laws in your area.
3. After the oil has drained, wipe the filter base
surface off and apply a film of new oil to the
gasket of the new replacement filter.
