SWING 500E2 SERVICE MANUAL
NOTE: If a new bearing is installed, a new pinion gear
must also be used.
6. Install the swing drive pinion so that the high point
(maximum eccentricity) is aligned with the turret bearing
high point. Check the backlash with a (0.008 in)
0.203 mm thick shim (Figure 6-5). If the pinion must be
moved to achieve proper backlash, contact your local
National Crane distributor.
NOTE: If equipped with a swivel, reconnect the hydraulic
lines as per removal tags.
7. Install the boom and lift cylinder following the procedures
outlined in Section 4- BOOM.
8. Reconnect the batteries.
Testing
Activate the crane and check for proper function.
NOTE: If the turret does not turn freely after bearing and
pinion replacement, contact your local distributor.
