MAINTENANCE AND LUBRICATION
Your HDR has been designed to give you excellent service and long life but
like all equipment, it requires proper and periodic maintenance. The truck
chassis itself is on a maintenance schedule recommended by the
manufacturer. Follow these guidelines and protect your vehicle warranty.
There are a number of different lubricants used on your HDR. The following
Lubricant Chart shows the proper lubricant and the most common brands
and specification which meet the requirements.
Use only safe practices when maintaining this equipment. Always shut off
the engine before reaching into pinch areas.
Inspect your vehicle and wheel lift system periodically for damage or evidence
of pending failure. Damaged or broken parts should be replaced immediately.
Never operate the carrier or any of its components if they are defective or
operating improperly. The cause of any binding or leakage should be
determined immediately and the problem promptly fixed.
Critical wear points on your HDR must be lubricated at regular intervals.
Sliding surfaces are to be cleaned and coated with a heavy grease
periodically. Cleaning every month is recommended for normal highway
operations, but this frequency will vary appreciably with the type of service.
Sliding on dirty wear surfaces will cause rapid wear. Fittings on linkage
pivots should be greased with an anti-seize lubricate every two (2) months,
again depending upon usage. The turntable bearing should be greased with
a general purpose lithium based grease every two (2) months.The turntable
gear should be greased with an open gear lubricant every two (2) months.
The following chart and diagram shows the location of these points, and
when and what type of lubricant to use.
Check the hydraulic oil level bi-monthly or after any leakage. A sight glass
has been provided on the hydraulic tank. The proper oil level is best checked
with all cylinders fully retracted. Use a Super Premium Grade Multi-Viscosity
hydraulic oil. (See Chart) (Automatic transmission fluid may be used in the
hydraulic system if necessary.)
The hydraulic filters located on the return side of the hydraulic tank come
equipped with restriction indicator gauges. The gauge shows the condition
of the filter element. When the needle reaches the red band (25 psi), the
filter is starting to bypass and the element needs to be changed. Failure to
