Routine Preventive Maintenance:  Direct Drive Rotisseries

Main Bearing Lubrication (6 months)
The 2 main shaft bearings should receive one pump of a NLGI Grade 2 Lithium based grease every 6 months. These bearings are located inside the cabinet on either end of the main shaft and are fitted with a standard Zerk fitting. They are accessed by removing the two side covers on each side of the cabinet. The bearing on the drive side is behind the reduction gearbox.

On units produced and shipped after April 1997, a Zerk fitting is located directly below the top door hinge on either side of the cabinet on the operator side. Care should be taken not to over lubricate these bearings.

Reduction Gear Lubrication (2500 hours)
It is recommended that the oil in the gearbox be changed after each 2500 hours of operation. Drain the oil by placing a drain pan below the gearbox and removing the drain plugs on the bottom of the primary and secondary gearboxes. When the gearbox is empty, reinstall the drain plugs and refill with Sentinel â S90/140 synthetic gear oil or equivalent, to 1" below the fill level check hole. Start the rotisserie and run for 5 minutes, then recheck the oil level and top off to 1" below the level check hole.

All seals should be visually inspected for leakage and replaced as needed. Examine the gearbox for signs of leakage, particularly around the motor attachment. Gearbox seal leakage at the motor could cause motor failure, and should be corrected immediately.

Spur Gear Bushing (6 months)
Check the spur gear bushings for signs of binding or lateral movement where the gear shank passes through the drive end drum. The gear should rotate in the Rulon inner bushing. If the gear and Rulon bushing are rotating in the drum sleeve instead, remove the gears and Rulon bushings, clean and refit. Do not lubricate the bushings or gears.

To remove the gears, mark the drum in relation to the shaft to ensure it is reinstalled in the same position. Remove the 6 bolts that retain the drum end to the hub (some units use only 4 bolts) and slide the drum end assembly toward the center of the cabinet. The spur gears can now be removed by loosening the set screw retaining the locking collar and sliding the gears out of the drum.

Inner Drum Sealing (6 months)
The condition of the high temp. sealant used to seal the inner drums to the cabinet walls and the inside corners of the cabinet should be checked and renewed if necessary. Use Dow Corning 732 RTVâ sealant.

Door Jamb Micro Switch (6 months)
Check the jamb switch for proper operation. The switch should move freely in the jamb without sticking or binding and the drums should stop when the doors are opened.

Speed Control Knob (6 months)
Check the speed control potentiometer for proper operation and the knob for tightness.

Switch Cover (6 months)
Check the switch dust and moisture cover for tears or damage and renew as needed.

Door Latch
Check the door latch mechanism for proper operation. If sticking occurs, remove the wedge pin, clean , refit and adjust.
