7. Use caution in determining the need for repacking. Know the difference between
controlled “weepage” which is necessary for lubricating the packing and “leakage”
beyond toleration. A dry-wiping packing is not necessary. The perfect packing
leaves an oil film that can be felt but not seen on the piston.
OIL REQUIREMENTS:
Change oil if it darkens materially or feels gummy or gritty. Do not use hydraulic-jack
oil, hydraulic fluids, brake fluids, or automatic transmission fluid. Use only oils that are
100 to 150 SSU at 100º F. Call the Autoquip Customer Assurance Department for
recommended brands, if necessary.
OIL CAPACITY:
Reservoir capacity (gallons) for the steel tank can be approximated by the following
formula:
Tank Width X Length X Height (in inches)
231 (cubic inches per gallon)
PIPE THREAD SEALANT
Loctite PST #567 pipe thread sealant or equivalent is recommended. Do not use
Teflon tape. Tape fragments can cause malfunctioning of the hydraulic system.
