General Instructions:
• Refer to "Suggested Tools" in the Parts Information Manual
Form 04581310 for quick reference to the tools recommended for the
following disassembly/assembly instructions. WARNING
• Repairs should be made only by authorized trained personnel.
Consult your nearest Ingersoll-Rand Authorized Service Center.
• Disconnect the power cord from the receptacle before
performing any maintenance on this or any other tool.
• Always use protective eyewear when performing maintenance
on a tool or while operating a tool.
• Use of non-Ingersoll-Rand parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
Lubrication
Whenever this product is disassembled, clean the parts and re-lubricate
them as follows:
1. Separate spindle, transducer, gear pack, and motor.
2. Disassemble spindle and gear case.
3. Clean and degrease all parts.
4. Once gear case is clean, apply prescribed amounts of
Ingersoll-Rand #222 Grease as follows:
a. 1 cc into the ring gear.
b. 1 cc into the first stage gears in the Gear head Assembly (22).
c. 1 cc into the second stage gears in the Spindle assembly (20).
d. 0.25 cc between and around gears, washers, and secondary stage
sun gear.
5. Wipe clean the Spindle Assemblies with a clean, dry and lint-free rag.
6. Work 2.5 cc of Ingersoll-Rand #222 grease into the inner diameter
of the Coupler (9).
Tool Dismounting Methods
It should be noted that disassembly of the tool into the modules will differ
slightly depending on the method used for mounting. If the tool is
mounted with the plate spacer in place, the tool can be disassembled by
following the first set of instructions (A). The reason for the plate spacer
is to allow the tool to be dismounted and remain fully assembled.
The tool can also be mounted with a bracket or mounting plate that takes
the place of the spacer. If this is the desired mounting method, the
mounting plate used must be the same thickness as the plate spacer
provided or the tool will not fit together properly. In this case the second
set of instructions (B) should be followed.
Disassembly
To aid in the disassembly process, the tool can be broken down into
modules. There are five different modules in the tool; the spindle
assembly, transducer, gear case assembly, motor assembly, and
electronics pod assembly. The following instructions are for breaking the
tool down into each modular assembly.
WARNING
• This procedure is to be performed by an authorized, trained
repair person to ensure proper functioning of the tool.
CAUTION
• When replacing a Gear Case Assembly, always use the
Assembly designed for that model.
General Instructions for Disassembly:
1. Do not disassemble the tool any further than necessary to replace or
repair damaged parts.
2. To protect part surfaces and to prevent distortion of housings and
threaded joints, use care when grasping the tool.
3. Avoid clamping non-metal surfaces unless directed otherwise.
4. Do not remove any press fit part or any part of an assembly unless its
removal is necessary for repair or replacement.
Disassembly into Smaller Modules
(A)
1. Using an Allen wrench remove the M8 Screws (4) that hold the tool to
the mounting plate and slide the tool out.
2. Remove the M3 Screws (5) that hold the Spindle Assembly to the
Transducer Assembly (17).
3. Remove the M6 Screws (24) that hold the gear case assembly to the
Transducer Assembly (17).
4. Remove the M6 Screws (26) that hold the gear case to the Motor
Assembly (27).
(B)
1. Using an Allen wrench remove the M8 Screws (4) that hold the tool to
the mounting plate. The spindle assembly will now become
disengaged.
2. Slide off the transducer, gear case, and motor assemblies.
3. Remove the M6 Screws (24) that hold the gear case assembly to the
Transducer Assembly (17).
4. Remove the M6 Screws (26) that hold the gear case to the Motor
Assembly (27).
Attachments
WARNING
• NEVER grasp the tool in a vise, as this will likely result in
damage to the tool causing wire leads to malfunction, which
increases the risk of electric shock.
Spindle - Disassembly
1. Use snap ring pliers to remove Retainer Ring (15).
2. Gently tap the end of the spindle on a hard surface while covering the
opposite end to dislodge the slip fit bearing.
WARNING
The input spindle is spring loaded and will therefore exert a force
once dislodged. Make sure to cover the end to avoid potential
injury.
3. Pull the Input Spindle Assembly (11) out of the Housing (3).
4. If necessary, using a bearing puller tool, pull the rear spindle Bearing
(14) off the Input Spindle Assembly (11). The bearing will most likely
become damaged in this process and should therefore be replaced.
5. Remove the Retaining Ring (13), and Washer (6).
6. Now tilt the spindle housing, causing the Spring (10), Coupler (9),
Spindle Lock (if applicable), Spindle (8), and Washers (6) and (7) to
slide out.
7. Using pick or screwdriver end, remove the Seal (1).
8. Press the two Needle Bearings (2) out of the Housing from either
direction.
Gear Case - Disassembly
1. Use snap ring pliers to remove Retainer Ring (18).
2. Carefully slide out all of the internal components: Washer (19),
Spindle Assembly (20), Washer (21), Gear Head Assembly (22), and
Washer (23).
3. Use a pick to pry out the Spacer Clip (25A) if necessary.
Disassembly of Electronics Pod
1. Use an Allen wrench to remove M6 Screws (35) from Flange (34).
2. Remove the M3 Screw (30) and slide the Cover (38) off.
3. Remove the two O-Rings (37) and remove the Memory Chip
Assembly (31).
4. Unscrew the Nut (36) and remove the Flange (34).
5. Use a small Flathead Screwdriver, carefully peel the dried sealant
out the ground slot.
6. Remove the M3 Screw (30) to free the ground wire.
7. Loosen the nut constraining the grommet in the strain relief and
unscrew the strain relief from the Housing (29).
8. Pry out the Clip (33) and slide out the Communication Board (32).

Form 04581351-Edition 2 3
9. Disconnect the motor temperature sensor connector, motor
communication connector, and the torque transducer connector from
the Communication Board (32).
10. Disengage female socket on the communication board from the male
connector on the motor cable.
11. Slide the Housing (29) off of the transducer and motor cables.
Tool Mounting Methods
It should be noted that assembly of the tool into the modules will differ
slightly depending on the method used for mounting. If the tool will be
mounted with the plate spacer in place, the tool can be assembled by
following the first set of instructions (A). The reason for the plate spacer
is to allow the tool to be mounted fully assembled.
The tool can also be mounted with a bracket or mounting plate that takes
the place of the spacer. If this is the desired mounting method, the
mounting plate used must be the same thickness as the plate spacer
provided or the tool will not fit together properly. In this case the second
set of instructions (B) should be followed.
