Large OTR Service Crane Owner’s Manual
Stellar Industries recommends the rst lter change to occur after the rst 250 hours of
service. The second, and every subsequent change, should occur after every 1,000 hours
of service. By following these guidelines, the hydraulic oil should last up to 6,500 hours.
Note: These recommendations are based on normal working parameters. If operating
in less than favorable conditions excessive dust, moisture, etc.), be sure to check the lter
gauge often for lter change notice.
Important: Prior to washing the Stellar crane, all electrical components must be covered
to prevent any water from being injected into the plastic housing. Avoid any direct water
pressure to any of the electrical components.
Touch up any chips or scratches to prevent further paint damage.
Every six (6) months, remove the hydraulic pump from the PTO and lubricate the splines
using Stellar PN 20885. Failure to lubricate shaft splines will cause damage to the PTO and
Hydraulic pump.

Rotation Gear Bearing Maintenance
Rotation Worm Gear and Open Gear Teeth
Use a heavy Moly Lube grease (Stellar PN 4460) to lubricate the worm gear and open gear
teeth of the rotation bearing. Slowly rotate the crane while pumping the grease between
the worm and rotation gear. This should be greased every month or sooner depending on
the usage of the crane. Another way of applying the grease would be to remove the gear
guard and brush the Molube grease between the gear teeth of the rotation bearing.
Do not lubricate the worm and rotation gear teeth with EP2 grease. EP2
grease will wipe the Molube grease clean causing excessive wear.
Worm Gear Bearings and Races
Apply three (3) pumps of EP2 grease to the two grease zerks located on the side of the
Rotation Gear bearing; every three months. After adding the EP2 grease, rotate the crane
fully.
Inner Gear Bearing Race
To lubricate the inner race of the large rotation gear bearing, open the compartment
door just below the crane. The grease zerk for the inner race bearing is located on the
compartment drip tray. The inner race will need to be lubricated with EP2 Grease weekly.
The rst week grease the inner race bearing at the one (1), three (3), ve (5), seven (7),
nine (9), and eleven (11) o’clock positions. The following week, grease the inner race
bearing in the two (2), four (4), six (6), eight (8), ten (10) and twelve (12) o’clock positions.
Rotate lubrication points every week.
