Remove the key then press off the front end plate(with bearing), o-ring and the lock ring. It may be necessary to remove the
bearing with a bearing separator if it came out of front end plate and stuck to the shaft of the shaft balancer.
5. Remove and discard dust shield from the shaft balancer.
6. Remove the bearing from the endplates by using the XPA0036 bearing removal tool to press out the bearings.
Shaft Balancer and Spindle Disassembly:
1. Grip the shaft end of the shaft balancer in a padded vise. With a thin screwdriver pick out the slotted end of the Retaining Ring
and peel out
2. Screw the threaded end of the XPA0025 Motor Lock Ring Wrench/Spindle Puller Tool into the Spindle until hand tight. Apply a
gentle heat from a propane torch or hot air gun to the large end of the Balancer shaft until it is about 100℃(212℉) to soften the
adhesive. Do not over heat. Remove the spindle assembly by using the slider to give sharp outward blows to the spindle. Allow
the parts to cool so they are safe to handle. Follow one of the appropriate directions below.
If the Bearing come out with the spindle, use a small Bearing Separator to remove it. Move onto step 3.
If the Bearing stays in the Shaft Balancer. Follow steps A - D below.
Procedure for removal of the Bearings from the Shaft Balancer:
A. Position the Set Screw in the top of the XPA0059 12 mm ID Bearing Puller.
B. Make sure the Retaining Ring is removed, then press the Bearing Puller into the I.D. of Bearing until the Bearing Puller hits
the bottom of the Shaft Balancer.
C. Thread the Set Screw down until it hits the bottom of the Shaft Balancer or becomes very tight. Grip the shaft end of the
Shaft Balancer in a padded vise.
D. Screw the threaded end of the XPA0025 Motor Lock Ring Wrench/Spindle Puller Tool into the Bearing Puller until hand
tight. Apply a gentle heat from a propane torch or hot air gun to the large end of the Shaft Balancer to re-heat it until it is
about 212℉(100℃) to soften the adhesive. Do not over heat. Remove the Bearing by using the slider to give sharp
outward blows to the Bearing Puller. Allow the Bearing Puller, Bearing and Shaft Balancer to cool. After cooling, unthread
the T-6 Motor Lock Ring Wrench/Spindle Puller Tool from the Bearing Puller. Back off the set screw. Secure the Bearing
Puller and Bearings in a Bearing Separator and press out the Bearing Puller.
3. The SUMAKE components are held in place by the light press fit of the Retainer. These components can be damaged during
removal and may need to be replaced if removed. To remove the Retainer, use an O-ring pick or a #8 sheet metal screw to grip
and pull out the Retainer. Remove the Valve and Filter from the bore in the Shaft Balancer. If the Retainer and Valve were not
damaged, they can be reused. However, the filter should be replaced on re-assembly.
4. Remove the bearing from the Spindle. Remove the Spacer. Dust Shield and Washer from the Spindle. Discard Dust Shield.
Housing Disassembly:
1. For Non-Vacuum (LSN) and Central Vacuum (LSC) machines follow the steps outlined in Section I below. For Self Generated
Vacuum (LSG) machines follow the steps outlined in Section “C”
A. This section is for LSN and LSC machines.
(a) Unscrew the Muffler Housing from the Housing.
(b) Remove the Bronze Muffler from the Muffler Housing and remove the Muffler insert from the cavity of the Muffler
Housing.
(c) For LSN machines move onto (d). For LSC machines move onto Section “B”
(d) Remove the LSN Shroud. Move onto Step 2.
B. This section continued from Section I for LSC Exhaust machines:
(a) Remove the Screw, Washer and Nut.
(b) Remove the Φ1”(28mm). LSC Swivel Exhaust Assembly or the Φ3/4”(19mm) LSC Swivel Exhaust Assembly from the
Shroud or Screen Abrasive Shroud.
(c) Remove the Shroud or Screen Abrasive Shroud from the Housing. Move onto Step 2.
C. This section is for LSG Exhaust machines:
(a) Unscrew the LSG Retainer with an 8 mm hex wrench.
(b) Remove the Φ1”(28mm) Hose LSG Swivel Exhaust Assembly from the Housing and LSG Skirt Adapter or LSG Shroud
Adapter.
(c) Pull the LSG Retainer out of the bore of the Swivel Exhaust Assembly and remove the two O-rings.
(d) Remove the Vacuum Shroud or Vacuum Skirt from the Housing. Move onto step 2.
2. Place the Speed Control to the midway position and remove the Retaining Ring.
NOTE: If the machine is a vacuum model, the vacuum exhaust must be removed (see Section 1 above for removal) before
the Retaining Ring can be removed with lock ring pliers. The Speed Control will now pull straight out. Remove the O-ring.
3. Unscrew the Inlet Bushing Assembly from the Housing. Remove the Valve Spring, Valve, Valve Seat, Valve Stem and O-ring.
