GP-6 (BELTS) SHAFT DISASSEMBLY
1. Use a wrench on the jam nut on the right side of the arbor shaft to keep the shaft assembly sta-
tionary and with the other hand remove the polishing hub by rotating it counter-clockwise.
2 Hold the expandable drum in one hand to keep the shaft assembly stationary and with an adjust-
able or box wrench, remove the jam nut on the right end of the unit by turning it counter-clockwise.
3. Lift the shaft assembly out of the bearing seats.
4. Loosen the set screw that secures the right-side bearing collar and slide the bearing off the shaft.
If the set screw has scarred the shaft, it may be necessary to file the burr off the shaft with a small,
fine, flat file or piece of emery paper.
5. Remove the diamond wheels and spacers from the shaft.
GP-6 (PADS) SHAFT DISASSEMBLY
1. Remove the polishing hub on the left side of the arbor shaft by turning it clockwise.
2. Lift the shaft assembly out of the bearing seats.
3 Loosen the set screw that secures the left-side bearing collar and slide the bearing off the shaft. If
the set screw has scarred the shaft, it may be necessary to file the burr off the shaft with a small,
fine, flat file or piece of emery paper.
4. Remove the Diamond wheels and spacers from the shaft.
GP-6 (Carbide) SHAFT DISASSEMBLY
1. With an adjustable or box wrench, remove the jam nut on the left end of the arbor shaft by turning
it clockwise.
3. Lift the shaft assembly out of the bearing seats.
4. Loosen the set screw that secures the left-side bearing collar and slide the bearing off the shaft. If
the set screw has scarred the shaft, it may be necessary to file the burr off the shaft with a small,
fine flat file or piece of emery paper.
5. Remove the carbide wheels and spacers from the shaft.
SHAFT REASSEMBLY
Reassembly of the shaft with the new diamond wheels is the reverse of the disassembly instructions.
Please keep the following points in mind when reassembling:
1. Install diamond wheels with the inside faces facing each other (Figs 33 & 34). Be sure the diamond
wheel bushings are installed.
2. The bearings have a permanently mounted bushing that extends from one side of the center
bearing. This extension must face away from the diamond wheels (Fig 35 & 36) on both ends of the
arbor shaft.
3. The arbor shaft collars have one recessed side and one flat side (Fig 37 & 38). The recessed side
should face the bearing and mate against the extended portion of the bearing bushing.
4. There should be a flange installed on both sides of each diamond wheel and the expandable drum.
Make sure the concave side of the flange (Fig 39) faces the wheels and drum.
5. When installing the shaft assembly back in the GP-6 Cabmaker, make sure the rubber mounted
bearings are centered in the bearing seat (Fig 40 & 41). If the bearings are not centered in the
bearing seats, make sure the aluminum spacers are in the correct order and that the bearings and
arbor collars are properly installed.
