General Instructions:
• Refer to "Suggested Tools " in the Parts Information Manual Form
04581336 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.
(Note: For offset tools, also separate offset gearbox)
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. 4.5 cc into the ring gear.
b. 4.5 cc into the first stage gears in the Gear Head Assembly (25).
c. 4.5 cc into the second stage gears in the Spindle Assembly (22).
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 (8).
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. For offset tools, there is a sixth module: the
offset gearbox 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 M4 Screws (5) that hold the spindle assembly to the
Transducer Assembly (16).
3. Remove the M8 Screws (17) that hold the gear case assembly to the
Transducer Assembly (16).
4. Remove the M6 Screws (21) that hold the gear case to the Motor
Assembly (27).
For Offset Tools:
Replace Step 3. with:
3a. Remove the M8 Screws (17) that hold the gear case
assembly to the Offset Gearbox Assembly (64).
3b. Remove the M6 Screws (52) and M8 Screws (51) that hold
the Offset Gearbox Assembly to the Transducer Assembly
(16).
(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 M8 Screws (17) that hold the gear case assembly to the
Transducer Assembly (16).
4. Remove the M6 Screws (21) that hold the gear case to the Motor
Assembly (27).
For Offset Tools:
Replace Step 3. with:
3a. Remove the M8 Screws (17) that hold the gear case
assembly to the Offset Gearbox Assembly.
3b. Remove the M6 Screws (52) and M8 Screws (51) that hold
the Offset Gearbox Assembly to the Transducer Assembly
(16).
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 (14)
2. Pull the Tas Spindle (13) and Driver (11) out of the Housing (3).
3. If necessary, pull out Roll Pin (12) to separate the driver from the tas
spindle.
4. Now tilt the Housing (3), causing the Pin (10), Spring (9), Coupler (8),
Spindle lock (if applicable), Spindle (7), and Washer (6) to slide out.
5. Using pick or screwdriver end, remove the Seal (1).
6. Press the two Needle Bearings (2) out of the Housing (3) from either
direction.
For Offset Tools:
Ignore Step 1.
Replace Step 2. with:
2. Pull the Driver (11) out of the Housing (3).
Replace Step 3. with:
3. If necessary, pull two Roll Pins (12) out of the Driver (11).
For Offset Tools:
Offset Gearbox - Disassembly
1. Use an allen wrench to remove M6 Screws (53) from the Gear
Housing Cover.
2. Slide the Gear Housing Cover off.
