5.2 Torque Wrench Drive Maintenance
5.2.1 If seal has small leak, replace seal because
of high hydraulic pressure hazard. Refer to
RPS for seal kit information.
5.2.2 Check zero leak plug / plug (Refer to RPS
for location) for o-ring extrusion and/or oil
leak. Re-tightening or replace plug. See
notes in Section 5.3.

guarantee exact hose assembly:
i. Service life
ii. Inspection intervals
iii. Replacement intervals
b.
As a general industry practice, the
maximum recommended hose assembly
service life is 6 years, including storage
time of the hose assembly. This will be
impacted by the application, pressure
cycles, cleanliness, environment, abuse,
etc.
5.2.5 Clean and lubricate bronze block and pawl
driver mating surfaces. Use appropriate
lubricant. Frequency:
a.
Depends on work environment -
increase frequency if tool is exposed to
sand or other abrasive material.
b. Increase frequency with high operating
pressure.
c. Increased frequency lengthens tool life.
5.2.6 Before each use:
a.
Check for oil leaks and repair
immediately.
b. Inspect tool structure (including splines,
torque wrench drive, reaction arm, etc.)
for cracks, chips, galling, or deformities.
If irregularities are found, service or
replace immediately.
c.
Check retractor, bronze block, and
retractor pin for fit.
d. Hoses and QC's:
i. Clean properly.
ii. Inspect thoroughly for damage,

e. Confirm torque wrench drive and wrench
cassette are:
i. Properly engaged – Retractor pin is
inserted properly in pawl driver slot
ii. Secured properly with socket head cap
screws, screws torqued per Table 4.6-1.
