WARNING

Always wear eye protection when operating or performing maintenance on this Barring Motor.

Always turn off the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this Barring 

Motor or before performing any maintenance on this Barring Motor.
Note:
 

When reading the instructions, refer to exploded diagrams in parts Information Manuals when applicable (see under Related Documentation 

for form numbers).

Lubrication

Ingersoll Rand No. 28

Ingersoll Rand No. 10

We recommend the use of an air line lubricator in the air supply line. 

Attach the unit as close to the tool as practical. We recommend using 

an Ingersoll Rand No. C28-04-FKG0-28 Filter-Regulator-Lubricator 

Unit. Where the lubricator cannot be permanently mounted, use 

Ingersoll Rand No. 3LUB8 lubricator. After each 40,000 cycles or one 

month, whichever occurs first, inject 1.5 cc of Ingersoll Rand No. 28 

Grease into the Grease Fitting (14). Do not grease excessively. Too 

much grease in the Gear Case (13) will cause heating.
Grease leakage from the spindle end is also an indication that an 

excessive amount of grease has accumulated within the Gear Case.

For continuous operation:

Continuous operation of geared motors generates heat which 

can cause grease to dry out and cake. The addition of fresh grease 

temporarily rectifies this problem. However, a small amount of oil 

should be added to the grease to replace the oil which was lost 

during continuous operation. The oil creates a slurry which makes 

the grease less likely to dry out and cake. After each eight hours 

of continuous operation or as experience indicates, remove 

Grease Fitting (14) and add ten drops of the recommended oil to the 

opening of grease fitting.

Maintenance
Disassembly

NOTICE

Always disconnect the air supply before doing any maintenance 

on this Barring Motor. Always use protective eyewear when 

performing maintenance on a tool or when operating a tool.

General Instructions

Do not disassemble the tool any further than necessary to replace 

or repair damaged parts.

Do not disassemble the Motor unless you have a complete set of 

new gaskets and O-rings for replacement.

Do not remove any part which is a press fit in or on a subassembly 

unless the removal of that part is necessary for repair or 

replacement.

Whenever grasping a tool or part in a vise, always use leather-

covered or copper-covered vise jaws to protect the surface of 

the part and help prevent distortion. This is particularly true of 

threaded members and housings.

The modular construction of the Series T480 Barring Motors 

permits selective disassembly whereby gearing can be separated 

from the power unit and disassembled without removing the 

Multi-Vane Motor from the Motor Housing, or the Multi-Vane 

Motor can be removed and disassembled without removing 

the gear train from the gear chambers. Because of the modular 

construction, the steps in the following Disassembly Procedures 

can be sequentially changed to meet the particular situation.

When removing a Planet Gear Shaft, always support the rear 

(short hub end) of the Gear Head, Gear Frame or Spindle and 

press on the front end of the Shaft being removed. The shaft holes 

through the webs are slightly tapered so that the Shaft is a tighter 

fit in the front web.

Pinion & Hose removal

Refer to drawing 45535762, and associated parts list, for 

additional information regarding part numbers and position 

within the assembly. It is not necessary to remove the Mounting 

Flange to proceed with this disassembly.

Disconnect, and remove if necessary, the Piston Activation Air 

Tubes, (two places) (22).

Remove the Piston Locking Plunger Assembly (18).

Disconnect Air Supply Tube (11).

Disconnect Swivel Elbow (two places) (12) from Barring Motor 

Assembly (13).

Place the Barring Motor on a workbench in a horizontal position, 

grasp Pinion (20) in copper-covered, or leather-covered, vise jaws.

NOTICE

Do not use excessive clamping force on the Drive Pinion. Grasp 

it just firmly enough to hold it. Make certain the Barring Motor is 

firmly supported on the workbench.
7.   Remove the Drive Pinion Screw (21).

8.  Loosen the vise and remove the Drive Pinion from the Barring 

Motor Assembly (13).

Separation of Major Module Sub-assemblies

NOTICE

Removal of the Mounting Flange is not necessary for service.

Refer to drawing 45505153, and associated parts list, for 

additional information regarding part numbers and position 

within the assembly. It is not necessary to remove the Mounting 

Flange to proceed with this disassembly.

If necessary, mark the location of the mounting flange to ensure 

proper orientation upon reassembly. Remove the six Mounting 

Flange Screws (10). Remove the Mounting Flange (9) from the 

Barring Motor.

Remove the four Screws (6) that attach the Motor-Brake/Gearing 

Assembly (1, 2) to the offset gear case and separate the Motor-

Brake/Gearing Assembly from the Drive Assembly (3).

Remove the three Screws (4) that secure the Motor/Brake 

Assembly (1) to the Gearing Assembly (2) and separate the two 

assemblies.
