Disassembly/Assembly Instructions – Stockade Filer/Saw
Important: Manufacturer’s warranty is void if tool is disassembled before warranty expires.
Notice: Dynabrade strongly recommends the use of their 52296 Repair Collar (sold separately) during assembly/disassembly activities. Failure to
use this collar will highly increase the risk of damage to the valve body of this tool. Please refer to parts breakdown for part identification.

Slider Housing and Gear Case Disassembly Complete.
Motor Disassembly:
1. Pull on the pinion gear of the 54554 Rotor and remove the air motor assembly from the 01488 Housing.
2. Fasten the 96346 Bearing Separator around the rear portion of the cylinder and place the separator on the table of the 96232 Arbor Press with pinion gear pointing toward
the floor. Press on the rear shaft of the rotor with flat nose 3/16 in. diameter punch, as a press tool, and remove it from the 02696 Bearing. The vanes can
now be removed.
3. Place the flat side of the 01478 Front Bearing Plate on the 96231 Tool Plate of the arbor press and push the pinion end of the 54554 Rotor from the 02694 Bearing. The
02649 Bearing can be pushed out of the front bearing plate allowing the removal of the 54529 Shims. The 01479 Spacer can be slipped off the rotor.
4. Remove the 02696 Bearing from the 02676 Rear Bearing Plate with the 96210 Bearing Removal Tool.
Motor Disassembly Complete.
Valve and Silencer Disassembly:
1. Position the 01488 Housing in the vise with the 52296 Repair Collar so that the air inlet is pointing up.
2. Hold the 94523 Inlet Adapter stationary with a wrench and remove the air fitting.
3. Remove the 94523 Inlet Adapter.
4. Remove the 95711 Retaining Ring from the inlet adapter and separate the 94521 Muffler Base from the 94522 Muffler Cap. Remove the bronze and felt mufflers.
5. Remove the air control ring from the 01488 Housing.
6. Use needle nose pliers to remove 01468 Spring, 01472 Tip Valve and 01464 Seal.
7. Use a 2.5 mm drive punch and remove 12132 Pin along with throttle lever.
8. Remove 95558 Retaining Ring and push 01469 Speed Regulator Assembly from housing. The o-rings can be removed.
Valve and Silencer Disassembly Complete.
Valve and Silencer Assembly:
Note: Make sure that all parts are clean and in good order before assembling. Follow all adhesive, lubrication, and torque instructions.
1. Install 01469 Speed Regulator Assembly (with o-rings) into the 01488 Housing securing it with the 95558 Retaining Ring.
2. Position the 01488 Housing in the vise with the 52296 Repair Collar so that the air inlet is pointing up.
3. Install 01464 Seal into housing.
4. Insert the 01449 Valve Stem into 01469 Speed Regulator Assembly so that the hole in the valve stem is visible through the air inlet opening.
5. Holding the valve stem in position and use a needle nose pliers to install the 01472 Tip Valve so that it intersects with the valve stem. Install the 01468 Spring (small end
against the tip valve).
6. Install the bronze and felt mufflers into 94522 Muffler Cap. Install the 94521 Muffler Base onto muffler cap.
7. Install 95438 O-Ring into the groove on the muffler base. Place 95375 O-Ring and 94526 Spacer into the recessed area of the muffler cap.
8. Slip 94523 Inlet Adapter through muffler assembly and install 95711 Retaining Ring into the groove on the inlet adapter.
9. Install 01633 Air Control Ring over the male thread of the inlet adapter and apply a small amount of Loctite®#567 (or equivalent) to the male threads of the inlet adapter
and install the entire muffler assembly onto the 01488 Housing (torque to 23 N•m/200 in. - lbs.).
10. Hold the 94523 Inlet Adapter with a wrench when installing the air fitting.
11. Install the throttle lever and 12132 Pin.
Valve and Silencer Assembly Complete.
Motor Assembly:
1. Slip 01479 Spacer onto the pinion end of the 54554 Rotor.
2. Place a .002 in. shim into the 01478 Front Bearing Plate and install 02649 Bearing into the front bearing plate. Press this assembly onto the 54554 Rotor by using the
96240 Bearing Press Tool.
3. Check the clarence between the rotor and the bearing plate by using a .001 in. feeler gauge. The proper clarence should be .001 in. to .0015 in. If it is necessary, adjust
clarence by repeating steps 1-3, adding or removing shims as required.
4. Once proper rotor gap clarence is achieved, install lubricated (oiled) vanes into the rotor slots, (use 95842 Dynabrade Air Motor Oil or equivalent).
5. Install the 01476 Cylinder so that it rests against the 01478 Front Bearing Plate while making sure that the air inlet holes of the 02676 Rear Bearing Plate align properly
with the air holes in the 01476 Cylinder.
6. Use the 96216 Bearing Press Tool to install the 02696 Bearing into the 02676 Rear Bearing Plate and to press the bearing plate with bearing onto the 54554 Rotor.
Note: The pinion end of the 54554 Rotor should be supported on the tool plate of the arbor press while pressing the rear bearing and bearing plate assembly onto the rotor.
