SWING SYSTEM
7. If necessary, remove the swing motor according to the
procedures found in this Section under SWING MOTOR
REMOVAL.
8. If necessary, remove the swing brake according to the
procedures found in this Section under SWING
GEARBOX AND BRAKE REMOVAL.
9. Cover the opening of the swing gearbox to ensure no
dirt, dust, etc., gets into the gearbox.
Installation
1. If removed, install the swing brake according to the
procedures found in this Section under SWING
GEARBOX AND BRAKE INSTALLATION.
2. If removed, install the swing motor according to the
procedures found in this Section under SWING MOTOR
INSTALLATION.
3. Attach a suitable lifting device to the swing gearbox and
lift and position the swing gearbox in place on the
mounting plate.
4. Install the capscrews, washers and spacers. Tighten the
bolts, refer to Fasteners and Torque Values, page 1-13.
5. Install the pinion gear on the output shaft and secure
with three bolts. Tighten the bolts, refer to Fasteners and
Torque Values, page 1-13.
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 checked and filled after 50 hours of
operation, drained and flushed out after approximately 250
hours of operation, and replaced with premium quality
SSGL-5 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:
1. Unscrew the drain plug; remove the breather and
dipstick to ensure all oil has been removed.
2. After oil is drained, replace the drain plug and any other
plugs that were removed to drain the oil.

3. Flush the case with a light flushing oil.
NOTE:
4. To refill with oil (see Figure 6-2), make sure the breather
is open. Insert oil through breather oil fill until it reaches
proper location on dipstick.
5. Tighten the breather and dipstick.

Oil Drain
Checking the Oil Level
1. Check the level on the dipstick on the swing gearbox.
2. If no oil is visible on the dipstick, add SSGL-5 weight oil
until the level is between min and max on the dipstick.
3. 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.

TMS800E SERVICE MANUAL
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.
