Replacing the V-Belts

WARNING: DISCONNECT ELECTRICAL POWER TO THE MACHINE BEFORE PERFORMING ANY MAINTENANCE.

1.Disconnect electrical power.

2.Remove sanding belt table.

3.Remove sanding disc table.

4.Remove sanding disc and shroud.

5.Remove pulley cover. Loosen set screw in pulley.

6.With second person holding belt housing, alternately loosen and remove two screws.

7.Remove V-belt from pulley (11). Remove pulley from shaft while separating assembled belt housing from the machine base.

8.Remove key from sanding belt drum shaft.

9.Loosen set screw in pulley (20).

10.Remove pulley. While removing pulley, slip V- belts from pulley.

11.Remove four screws from base. With assistance of the second person, lift base from stand.

NOTE: Place base on bench. As an alternative, the stand may be used to support the base while remov- ing drive motor screws.

12.Place base on bench with underside of the base facing up.

13.Remove two hex head screws, two nuts, and two washers from the motor base on the shaft side of motor.

14.Loosen (but do not remove) two hex bolts, two nuts, and two washers on the side of motor base opposite the motor shaft.

15.Tip motor enough to provide clearance between end of shaft and wall of base. Remove motor drive belt.

16.With base still on the bench, slip V-belt (15) over end of idler shaft.

NOTE: Install V-belt for sanding belt first, followed by the motor V-belt.

17.Install replacement V-belt over end of motor shaft.

18.Install two hex bolts, two nuts, and two washers in the motor base on the shaft side of motor. Tighten all four hex nuts and hex head screws.

19.Install key in idler shaft with keyway facing up. Install pulley (20) on idler shaft.

20.Install motor V-belt (18) in outermost groove of pulley (20) and on pulley (18) on motor shaft.

21.Position motor belt (18) on idler shaft so it is parallel with the inner wall of the base. Tighten set screw in pulley (20).

22.Place assembled base on stand. Secure with four screws, washers, nuts.

NOTE: Because of the weight of the belt housing, a second person should hold the belt housing in position while installing pulley (10).

23.Hold belt housing in position in bracket (3). Start two screws (13) in threaded holes in platen. Install key (8) in shaft.

NOTE: Because of the length of screws (13), the screws will have to be installed alternately. As the screws are installed, there will be enough clearance to slide the belt drum drive pulley a little at a time onto shaft (8).

24.Alternately install two screws (13). As the screws are tightened, slide pulley (10) onto the idler shaft as allowed by the protrusion of screw heads.

Make sure V-belt remains on pulleys (11 and 20).

25.When screws (13) are fully installed, align pulley (20) with pulley (11). Tighten set screw (10).

26.Install shroud (53) on base and secure with four screws and washers.

27.Install pulley cover (12) and secure with two screws.

28.Install disc (58) onto shaft (16) and over key. Position the disc on the shaft to provide clear- ance between plate (55) and the sanding disc. Using long T-handle Allen wrench, tighten set screw (57).

NOTE: There is a close fit between the edge of disc

(58)and the disc shroud. To ease installation and positioning of the disc, use an L-shaped tool (such as an Allen wrench) under the outer edge of the disc to support and position the disc while tightening the set screw.

29.Install plate (55) and secure with four screws

(56). Check for clearance between plate (55) and the sanding disc.

30.Install table (60) onto rod (74). Position table so it is level and tighten screw (65) against rod (74).

31.Install assembled table (88).

32.Connect electrical power and operate machine to check operation.
