Installation Instructions
1. UNPLUG THE MACHINE , OIL PUMP and HOSE
2. Remove 4 screws & the top motor cover, taking care
to disconnect the 2 lamp wires .
3. Remove 4 screws from the motor side cover.
4. Removethe4groundwirescrewsfromthebackofthe
grinding head.
5. Disconnect the 2 motor lead wires, and set the motor
cover aside.
6. Remove the 2 front grinding head bolts. Loosen the
remaining bolt and pivot the motor towards the oil
tank.
7. Remove 2 motor clamps, and set the motor aside.
8. Remove 3 motor mount plate bolts, washers, and the
2 steel sleeves from the rubber bushings.
9. Install the rubber bushings in the new plate, noting the
thicker side is towards the head in the lower holes,
and away from the head on the upper hole. The lower
holes also use the steel sleeves.
10. Mount the new plate using the screws and washers
removed previously. Tighten the bottom bolts com-
pletely and turn the top bolt in about half way.
11. Feed the belt around the idler pulley.
12. Mount the motor loosely, replacing the clamps and
nuts.
13. Put the belt on the motor and make sure it is tracking
correctly on all three pulleys.
14. Slide the motor back and tighten the motor clamp
nuts, taking care to keep the belt square to the
grinding head and motor.
15. Adjust the idler position by loosening and tightening
the 5/16" nuts on the idler shaft.
16. Check that the belt tracks on all three pulleys.
17. Rotate the head back into position and tighten the 3
bolts.
18. Connect the 4 ground wires and the 2 motor lead
wires.
19. Replace the 3 sided cover and the 4 screws securing
it.
20. Plug in the unit and start the grinding head, being
careful to keep clear of the pulley and belt.
21. Adjust the belt tension as outlined in the instructions.
22. TURN OFF AND UNPLUG THE UNIT
23. Connect the lamp to the matching black and white
wires, while replacing the top cover and it’s 3 screws.
24. Connect the oil pump cord and hoses.
Belt Tension Adjustment for 2075
1. Remove the top cover over the grinding head motor
and unplug the oil pump.
2. Loosen the locknut on the 1/4" bolt at the top of the
motor mounting plate.
3. Back out the bolt until it clears the rubber mount, and
the motor is supported by the belt.
4. Checkthedrivebelt to ensurethatitis properly seated
in the motor, idler, and shaft pulleys.
5. The bottom of the motor mounting plate should be
parallel with the cross slide casting. If it is not, loosen
the 4 nuts under the motor and reposition it until the
plate is parallel, and tighten the nuts.
6. Turn in the adjusting bolt until it contacts the rubber
mount. Start the motor, making sure that items are
clear of the drive belt and pulley.
7. Carefully turn the adjusting bolt in. ( A 7/16" nutrunner
or socket and extension will be helpful in doing this.
) As the bolt is turned in, you will notice that there are
positions where the upper part of the belt will vibrate
or “flop”. After approximately 6 turns in, you will be
past these vibration points and the belt will seem quite
loose. It may even be rubbing against the top of the
slot in the casting. Now back out the bolt, (increasing
the belt tension) stopping when the upper part of the
belt begins to vibrate. At this point turn the bolt back
in 1/4 turn, so the belt just stops vibrating. Tighten the
locknut while maintaining this position. The belt
tension is now set to the optimum position for smooth
operation. Turn the head on and off several times to
check for belt slippage on start-up.
If the belt should slip the tension setting may be
increased as follows. Begin to back out the bolt 2 to
4 turns while observing the upper section of the belt.
As tension is increased the belt will vibrate and then
slowly stop as a nodal point is reached. When both
the upper and lower parts of the belt have stopped
vibrating, tighten the locknut. This is the maximum
belt tension recommended. DO NOT run the unit with
the adjusting bolt backed out farther than outlined
above.
