Converting 3 x 4 in. (75 x 00 mm) NV Machines to SGV Shrouded Machines
Additional Disassembly Instructions for Converting 3 x 4 in. (75 x 100 mm) NV Machines to SGV Shrouded
Machines.
1. Remove the Muffler Housing Assembly with a 21 mm socket or adjustable wrench.
2
. Keep the original parts not used for the conversion in a safe place so the machine can be converted back later.
General Assembly Instructions to convert to 3 x 4 in. (75 x 100 mm) SGV Shrouded Machines:
. Remove Vacuum Cover Plate from Sander Housing.
2. Place Shroud Seal around exhaust hole and then around Housing.
3. Snap the Exhaust Adapter into the exhaust hole.
4. Slide the inlet end of the Swivel Exhaust Assembly into the Exhaust Adapter.
5. Lightly grease the two O-rings and place them in the grooves of the 0,000 RPM SGV Retainer.
6. Slide the SGV Retainer into the SGV Swivel Exhaust Assembly as shown in the Figure.
7 Apply a small amount of a non-permanent pipe thread sealant to the threads of the SGV Retainer.
8. Slide the Swivel Exhaust Assembly onto the SGV Shroud Exhaust Adapter Fitting while at the same time inserting
the SGV Retainer into the Sander Housing exhaust port.
9. Screw the Assembly into the Sander Housing. Insure all parts are properly aligned and torque the SGV Retainer
Assembly to 36-48 in-lbs (4.-5.4 N-m).
10. Grasp the female Swivel Fitting on the SGV Exhaust Assembly and turn the fitting to thread the male end of the
Vacuum Hose into the Swivel Fitting until the hose is tight.
11. Place a small amount of a non-permanent pipe thread sealant to the threads of the male end of the ¼” Air Line fit-
ting on the Vacuum Hose Assembly and thread it into the inlet port of the Sander Housing. Use a 9 mm wrench
to hold the inlet port Bushing and torque the Air Line fitting to 80-100 in-lbs (9.0-11.3 N-m).
2. Open the Vacuum Bag and turn it partially inside out to expose the Vacuum Bag Fitting neck hole and strap area.
Remove the Vacuum Bag Fitting from the end of the Vacuum Hose Assembly. Slip the Vacuum Bag neck opening
over the neck of the Vacuum Bag Fitting. Secure the Vacuum Bag to the Vacuum Bag Fitting with the hook and
loop strap by wrapping it around the groove in the Vacuum Bag Fitting. Turn the Vacuum Bag right side out and
attach a disposable Vacuum Bag Insert over the Vacuum Bag Fitting and close the Vacuum Bag. Thread the end
of the Vacuum Hose Assembly into the Vacuum Bag Fitting.
