Assembly Of The Reverse Valve; Assembly Of The Impact Mechanism - Ingersoll-Rand 2161P Series Instructions Manual

Assembly of the Reverse Valve

1. Coat a new Reverse Valve O–ring (28) with O–ring
lubricant and install it in the groove on the Reverse
Valve (29).
2. Install the Reverse Valve in the reverse valve bushing
with the slotted end trailing,making sure that the the
index mark on the Reverse Valve is aligned with the
index mark on the Bushing.
See Dwg. TPD1912–1.
REVERSE LEVER IN
FORWARD POSITION
The Reverse Valve must be installed and indexed
with the bushing as directed in Step 2 and Dwg.
TPD1912–1. Failure to do so will cause improper
operation of the Reverse Valve.
3. Insert the Reverse Lever (16) through the rear of the
Backcap (14).
4. Slide the Reverse Lever Spring (18) over the shaft of
the Reverse Lever and secure the Spring and Reverse
Lever by installing the the Reverse Lever Snap Ring
(17) in the groove in the shaft of the Reverse Lever.
Rotate the Reverse Lever so that it is pointing to the

Assembly of the Impact Mechanism

1. Coat the Hammer (38) with a light film of
Ingersoll–Rand No. 170 Grease.
2. Slide the Hammer into the Hammer Frame (36)
exactly as it was when you marked it prior to
disassembly.
In order to utilize both impacting surfaces on the
Hammer and thus equalize the wear on each
hammer jaw, the Hammer can be flipped over so
that the arrow is pointing downward.
3. Replace the Hammer Pins (37).
4. Examine the base of the Anvil (39) and note its
contour. While looking down through the Hammer
Frame, swing the Hammer to its full extreme one way
or another until you can match the contour of the
Anvil. Enter the Anvil into the Hammer Frame and
through the Hammer.
Assembly of the Anvil
1. Place the Hammer Frame Washer (30), hub side first,
over the hub of the Rotor and against the Front Rotor
Bearing.
2. Set the assembled impact mechanism down over the
splined hub of the Rotor. If the impact mechanism was
disassembled, refer to Assembly of the Impact
Mechanism.
3. Position the new Hammer Case Gasket (34) on the
Housing.
4. Work approximately 12 to 15 cc of Ingersoll–Rand
No. 170 Grease into the impact mechanism.
5. Smear a thin film of Ingersoll–Rand No. 170 Grease on
the inside surface of the Hammer Case Bushing (36)
and place the Hammer Case (35) down over the Anvil
and against the Motor Retainer.
6. Install the Backcap Bolts and using a No. 27 TorxR
drive wrench or bit, tighten them to 10 to 12 ft–lb
(13 to 16 Nm) torque.
7. Remove the Impactool from the vise and inject 2 to
4 cc of Ingersoll–Rand No. 170 Grease into the Grease
Fitting (15).
