or copper–covered vise jaws with the Back Cap (2)  
upward.  
2. Using a hex wrench, unscrew and remove the Cap  
Screws (21) and Lock Washers (22).  
LUBRICATION  
Each time a Series 1712B2/VW–1035 Impactool is disas-  
sembled for maintenance and repair or replacement of  
parts, lubricate the tool as follows:  
3. Lift the Back Cap off the Housing. Remove the Seal  
(3) from the inside of the Back Cap.  
1. Work approximately 10 cc of Ingersoll–Rand No. 100  
Grease into the impact mechanism. Coat the Anvil  
(26) lightly with grease. Also coat the inside of the  
Hammer Case Bushing (17) with grease.  
2. Use Ingersoll–Rand No. 50 Oil for lubricating the  
motor. Inject approximately 3 cc of oil into the air  
inlet before attaching the air hose.  
4. Remove the Clamp Washer (5) from the Housing.  
5. Remove the assembled motor from the vise jaws and  
using a plastic hammer, tap the splined shaft of the  
Rotor (8) to dislodge the Rotor from the Front Rotor  
Bearing (12).  
6. Lift the Motor Housing off the Rotor, Rear End Plate  
(6) and Rear Rotor Bearing (7). The Rear End Plate  
and Rear Rotor Bearing will remain together as a  
unit.  
7. Remove the Vanes (9) from the Rotor.  
8. Pull the Rear End Plate off the Rotor.  
9. Open a set of vise jaws wide enough to clear the hub  
of the Rear End Plate and sharply rap the hub end of  
the End Plate on the top of the jaws to dislodge the  
Rear Rotor Bearing.  
10. Remove the Cylinder Dowel (13) and lay the Motor  
Housing on top of the vise jaws with the Front Rotor  
Bearing (12) downward between the jaws. Using a  
soft drift pin, tap the Bearing out of the Housing.  
11. To remove the Cylinder (10) and Front End Plate  
(11), thread four 1/4”–20 thread socket head cap  
screws that are at least 3” (75 mm) long into the Back  
Cap end of the Housing. Grasping the Housing with  
the installed screws downward, sharply strike the  
heads of the screws on a sturdy table to dislodge the  
Cylinder. The Cylinder should drop out of the Hous-  
ing after a few impacts. If it does not, proceed as fol-  
lows:  
DISASSEMBLY  
General Instructions  
1. Do not disassemble the tool any further than neces-  
sary to replace or repair damaged parts.  
2. Whenever grasping a tool or part in a vise, always use  
leather–covered or copper–covered vise jaws to pro-  
tect the surface of the part and help prevent distor-  
tion. This is particularly true of threaded members  
and housings.  
3. Do not remove any part which is a press fit in or on a  
subassembly unless the removal of that part is neces-  
sary for repair or replacement.  
4. Do not disassemble the tool unless you have a com-  
plete set of new gaskets and O–rings for replacement.  
Disassembly of the Tool  
1. Grasp the tool in leather–covered or copper–covered  
vise jaws with the square drive upward.  
2. Using a hex wrench, unscrew and remove the four  
Hammer Case Cap Screws (19), and Hammer Case  
Cap Screw Lock Washers (20).  
3. While lightly tapping the end of the Anvil (26) with a  
plastic hammer, lift off the Hammer Case  
Assembly (16).  
The following procedure requires the use of heat.  
Take all precautions necessary to prevent being  
burned.  
4. Remove the Hammer Case Gasket (18).  
4
 
MAINTENANCE SECTION  
a. Carefully heat alternate sides of the Housing until  
it is very warm.  
b. Using thick, heavy gloves to avoid being  
burned, grasp the Housing and repeat the attempt  
to dislodge the Cylinder.  
Excessive clamping pressure will distort the Motor  
Housing and make motor installation extremely  
difficult. Do not insert the hammer case end of the  
Motor Housing more than 1” (25 mm) into the vise  
jaws.  
12. Remove the two Air Port Gaskets (14) and Gasket  
supports (15) from the Housing.  
8. Lightly clamp the Motor Housing in leather–covered  
or copper–covered vise jaws with the motor bore  
upward.  
9. Lubricate and install a new fiber Gasket Support  
(15) into each of the air ports inside the Motor Hous-  
ing.  
ASSEMBLY  
General Instructions  
1. Always press on the inner ring of a ball–type bearing  
when installing the bearing on a shaft.  
2. Always press on the outer ring of a ball–type bearing  
when pressing the bearing into a bearing recess.  
3. Whenever grasping a tool or part in a vise, always use  
leather–covered or copper–covered vise jaws. Take  
extra care with threaded members and housings.  
4. Always clean every part and wipe every part with a  
thin film of oil before installation.  
10. Install an Air Port Gasket (14) into each opening  
against the Retainer with the flat end of the Gasket  
away from the Retainer.  
11. Using an assembly rod that is approximately 3/16”  
diameter x 8” long (5 mm diameter x 203 mm long),  
insert the rod through cylinder dowel holes in the End  
Plates and Cylinder to align the components. Allow  
the rod to protrude through the Front End Plate far  
enough to enter the dowel hole in the bottom of the  
motor bore.  
5. Apply a film of O–ring lubricant to all O–rings before  
final assembly.  
Assembly of the Motor  
12. Insert the rod into the motor housing dowel hole and  
slide the assembled motor along the rod into the Mo-  
tor Housing. The assembly will be at the proper depth  
when the Rear End Plate is slightly below the face of  
the Motor Housing. Remove the assembly rod and  
insert the Cylinder Dowel (13) into the assembly.  
13. Place the Motor Clamp Washer (5), concave side  
first, over the hub of the Rear End Plate so that the  
outer rim of the Washer contacts the End Plate.  
14. Install the Seal (3) on the inside of the Back Cap.  
15. Install Back Cap on Housing and secure with Cap  
Screws (21) and Lock Washers (22). Tighten to

recess at the hammer case end of the Motor Housing  
(1).  
2. Slide the Front End Plate (11), bronze face first, over  
the spline hub of the Rotor (8).  
3. Stand the assembled Rotor and End Plate upright,  
grasping the rotor spline with leather–covered or  
copper–covered vise jaws.  
4. Place a Vane (9) in each slot in the Rotor.  
5. Slide the Cylinder (10) down over the Rotor, aligning  
the holes in the Cylinder with those in the Front End  
Plate.  
6. Using a sleeve that will contact only the outer ring of  
the Rear Rotor Bearing (7), press the Bearing into the  
Rear End Plate (6).  
7. Using a sleeve that will contact only the inner ring of  
the Rear Rotor Bearing, press the assembled Bearing  
and End Plate onto the short hub of the Rotor.  
16. If Plugs (4) were removed or are being replaced,  
apply pipe thread sealant and tighten to 10–20 ft–lb  
(13.5–27 Nm) torque.
