6. Connect the hydraulic lines to the swing brake.
7. Connect the hydraulic lines to the swing motor.
8. Service the gearbox as indicated under Servicing.
Servicing
As with all highly stressed mechanisms, reasonable
operating procedures are always required. Normal
maintenance should only consist of proper lubrication and a
periodic check of mounting bolt torque values. Lubrication
consists of maintaining the gearbox oil level. Oil in a new
gearbox should be drained and flushed out after
approximately 250 hours of operation, and replaced with
premium quality AGMA No. 4 EP gear lube after
approximately 500 hours of operation or each year,
whichever occurs first. Operation in high humidity or polluted
air areas will require more frequent changes to minimize
moisture or contaminate accumulation. Change the oil as
follows.
a. Unscrew drain plug; remove breather and dipstick to
ensure all oil has been removed.
b. Flush the case with a light flushing oil.
NOTE: Cleaning of the gearbox with a solvent is
recommended to prevent an accumulation of grit
and grime. Avoid steam cleaning where moisture
and dirt might be driven into the vent of the swing
bearing.
c. After oil is drained, replace the drain plug and any
other plugs that were removed to drain the oil.
d. To refill with oil, make sure the breather is open. Fill
until proper location on dipstick.
e. Tighten breather and dipstick.
Checking The Oil Level
a. Check level on dipstick
b. If no lubricant is visible on dipstick, add GL-5 until
between minimum and maximum on dipstick
c. Replace the dipstick in the brake housing.
Testing
1. Test swing of superstructure in each direction. Stop and
start swing several times.
2. Inspect for hydraulic leaks and repair as necessary.
