WARNING
Always wear eye protection when operating or performing maintenance on this Barring Motor.
Always turn o 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 rst, 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 recties 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 tting.
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 t 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
t 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.

When grasping a Motor or one of its parts in a vise, always use
leather or copper vise jaw covers to protect the surface of the
part and reduce the likelihood of damage. This is particularly
important when clamping threaded members, shafts with splines,
etc. Apply o-ring lubricant to each o-ring before assembly and use
only new gaskets when reassembling the Motor.
When installing Planet Gears in a Spindle, Gear Head or Gear
Frame, always support the front web and press in the shaft from
rear to front. Shaft holes through the webs are slightly tapered
so that shaft is tighter in front web. Always replace Planet Gears
in sets.
