10.0 MAINTENANCE
10.1 GENERAL
•
All maintenance and/or repair work should be done using good workmanship practices and proper tools.
•
The work area should be clean and free of dirt.
•
When O-rings and backup rings are removed, every effort should be made to avoid the contact of tools with the critical
surfaces of parts. Surface deformities could cause degradation of seals and failure.
•
It is good practice to replace both O-rings and backup rings once removed. Cut and damaged O-rings normally result in
fluid leakage.
•
If cylinder bore is found to be rusty, it may be honed to a maximum diameter of 3.257 inches
•
(82.73 mm) and a surface finish of 16 micro inches. If pitting in the bore cannot be removed by this process, the jack
cylinder must be replaced before the jack can be returned to service.
•
At this time, flush old hydraulic fluid and dirt from overall system and replenish with new, clean hydraulic fluid.
•
When refilling the hydraulic system, use MIL-PRF-5606 hydraulic fluid and fill to 1.5 inches (3.8 cm) from reservoir vent
cap.
•
Jacks shall be maintained and repaired in accordance with the
manufacturer’s instructions. Such maintenance and repair
shall be carried out by qualified persons.
•
No modifications shall be carried out which adversely affect the compliance of the jack with draft standard 2006/42/EC.
