Lubrication
Ingersoll Rand strongly emphasizes the importance of proper
lubrication for achieving top performance and maximum durability
with this starter. Either one of two lubrication systems is
recommended.
For typical starter installations where the cranking cycle is less than
10 seconds, we recommend an Ingersoll Rand No. HDL3 Lubricator
installed as shown in Dwg. TPC585. Use either diesel fuel or 10W
nondetergent motor oil for lubricating the starter.
NOTICE
When an HDL3 Lubricator is used, make certain that the oil sup-
ply line pressure is no greater than 5 psi. If there is pressure on
the line, the lubricator will continuously leak lubricant through
the starter and out of the exhaust.
If the cranking cycle is more than 10 seconds, we recommend the
Ingersoll Rand No. Lubricator NL-24-8 installed in the main air
supply line. Use a good quality 10W nondetergent oil and adjust the
lubricator to ow 1 to 3 drops per second.

Installation
NOTICE
For maximum performance, read this manual prior to
installation or operation of Series 150BMG Starters.
General Information
1. This starter must be installed according to the instructions in this
manual.
2. Ingersoll-Rand recommends that on all vehicular installations and
on stationary engines subject to vibration, hoses of the specified
diameter be used instead of rigid pipe connections. Vehicle and
engine vibration will soon loosen rigid pipe connections, whereas
hoses will absorb the vibration, and connections will remain
tight.
3. When mounting a starter, make the hose connections at the
receiver and have the starter end of the hose handy for attaching
to the starter.Wherever possible, attach the air hoses to the
starter before mounting the starter on the flywheel housing.
There are two reasons for following this procedure:
a. After mounting the starter, it is often impossible to make hose
connections due to space limitations.
b. Once attached, the hoses carry some of the weight of the
starter, making it easier to complete the mounting.
4. Engine design often demands that the starter be mounted
underneath in extremely close quarters. Therefore, even though
two of the mounting bolt holes are easy to get at, the third
one is often difficult to reach. The tools usually needed in the
installation of a starter are a regular ratchet wrench, sockets,
universal joint, socket extension and a single or double-end
ratcheting box wrench.
5. The efficiency of a starter can be greatly impaired by an improper
hook-up. Hoses smaller than those recommended will reduce the
volume of air to the motor, and the use of reducers in the exhaust
port will restrict the exhaust and choke the motor.The use of tees
and elbows and the length of the supply line should be kept to
a minimum. In normal installations, hoses running from the air
tank to the starter should be No. 20 and fittings should be 1-1/4”.
Control hoses should be No. 4 and fittings should be 1/4”.
6. A leak in any of the connections means that the system will drain
overnight and will have to be repressurized the next morning
by using another vehicle or compressor. Make the connections
right the first time to avoid unnecessary costs and delays. On all
threaded connections throughout the system, use Ingersoll-Rand
No. SMB-441 Sealant, non-hardening No.2 Permatex,
Loctite®* Pipe Sealant or Perma-Lok® LH050**. Always run the air
supply line from the side or top of the receiver, never at or near
the bottom. Moisture will collect at the bottom of the receiver

03524832_ed12 3
causing corrosion and icing in cold weather. If either of these
conditions exist, the starter will not operate. After all connections
have been made, check each joint with a soap bubble test,
7. Installation of a“glad hand”for emergency repressurizing the
system is recommended.To keep the“glad hand”clean and free
of dirt, and to protect it from distortion, a second“glad hand”
closed by a pipe plug can be mated to it, or a glad hand protector
bracket can be used.
8. Whenever possible, always mount the starter so that the exhaust
port is downward This will help prevent any accumulation of
water in the starter motor.
9. For increased protection during extended shelf life, the motor
components of the starter have been coated with
Ingersoll Rand No. 50 Oil. This oil will be dispersed during the first
few cycles of the starter.
Relay Valve Location
Ingersoll-Rand recommends that the Relay Valve be mounted on the
air tank. As an alternate location, the Relay Valve can be mounted
on the starter. Mounting on the starter gives better control of the air
supply closer to the point of use and provides more starts per tank
of air. However, mounting on the starter adds overhung weight and
subjects the air supply lines to dynamic pressure at all times.

Orientation of the Air Starter
If the factory orientation will not t your engine due to radial location
of the Drive Housing or location of the inlet and/or exhaust ports,
re-orient the starter as follows:
1. Refer to the dimension illustration and note that the drive
housing can be located in anyone of eighteen radial positions
relative to the gear case.The exhaust port (motor housing) can
be located in any one of four radial positions relative to the Gear
Case, and the air inlet (Motor Housing Cover) can be located in
any one of four radial positions relative to the exhaust port.
2. Study the engine mounting requirements, and determine the
required orientation of the Drive Housing relative to the Gear
Case. If the Drive Housing has to be reoriented, remove the
twelve Drive Housing Cap Screws and rotate the Drive Housing to
its required position.
NOTICE
Do not separate the Drive Housing from the Gear Case Cover.
Reinstall the Drive Housing Cap Screws and tighten them to 100 in-lb
(11 Nm) of torque.
3. When orienting the Drive Housing relative to the Gear Case,
determine if the exhaust port will be at the bottom and if the
inlet port will be favorably located for hose installation. If either
or both of these members must be reoriented, remove the four
Motor Housing Cover Cap Screws, and rotate the Motor Housing
and/or Motor Housing Cover to its desired position.
NOTICE
Do not separate these members from each other or from the
Gear Case. Reinstall the Motor Housing Cover Cap Screws and
alternately tighten them to 25 ft-lb (34 Nm) of torque.
Mounting the Air Starter
1. Study the piping diagram Dwg. TPC585.
2. The air receiver tank for a starter installation must meet
SAE J10B specifications or conform to ASME specifications. It
must have a working pressure capability equal to or greater than
the maximum pressure at which the starter will be operated.
3. When connecting the starter to a receiver tank that is already in
service, bleed off the air pressure by opening the drain valve.
WARNING
Bleed o the air pressure through a valve or petcock. Do not
remove a plug from the tank while the tank is still pressurized.
Drain o any water that has accumulated in the bottom of the
tank.
4. Using a 1-1/4”short nipple, install the SRV125 Starter Relay Valve
on the end of the receiver tank as shown in the piping diagram.
NOTICE
Make certain the connection is made to the inlet side of the Relay
Valve indicated by the word‘IN”cast on the valve body.
5. Install the No. SMB-618 Starter Control Valve on the dash panel
(for vehicular installations) or some other appropriate panel (for
stationary installations).
6. Attach No.TA-STR-100 Starter Instruction Label to the control
panel adjacent to the Starter Control Valve.
7. Mount the No. 150BMP-1064 Air Pressure Gauge on or adjacent
to the control panel. It should be located where it is readily visible
to the operator of the ControlValve.
8. Connect the Starter Control Valve to the Relay Valve with 1/4”
hose. Install a Tee in this line with a short feeder hose to the
Pressure Gauge.
NOTICE
Make certain the hose is connected to the“SUPPLY”side of the
Starter Control Valve.
9. To determine the exact length of 1-1/4” air hose required, run a
piece of heavy-duty hose or some other flexible tubing of the
same diameter from the Relay Valve on the receiver to the Starter
location on the engine.
10. Attach the 1-1/4”air hose to the outlet side of the Relay Valve, and
run the hose through the frame to its final position at the starter
location.
11. At this point, determine if it is feasible or practical to attach the
hose to the starter before or after the starter is actually mounted.
In many cases, it may be necessary to attach the hose to the
starter before mounting.
12. If possible, liberally grease the teeth on the ring gear with a
good, sticky gear grease or motorcycle chain lube.This will help
promote the life of the ring gear and the Starter Pinion.
13. Place the starter into position, and mount it on the flywheel bell
housing. Tighten the mounting bolts to 100 ft-lb (136 Nm) of
torque.
14. If the exhaust is not to be piped away, install a No. 150BM-A674
Muffler or No. 150BM-A735 Road Splash Deflector in the exhaust
port on the Motor Housing of the Starter.
15. Pressurize the complete starting system and check every
connection with a soap bubble test. There must be no leaks.
Barring Over the Engine
Occasionally, for setting injectors and/or for timing purposes, it may
be desirable to bar over the engine in such a manner that any given
piston can be stopped at any given location.This is very easily done
with a 150BMG Starter.

4 03524832_ed12
1. Disconnect the 1/4”hose at the“OUT”port on the Drive Housing,
and plug the hole in the Drive Housing with a 1/4”pipe plug.
2. Remove the 3/8”pipe plug from the center of the Motor Housing
Cover.
3. Engage the Drive Pinion with the flywheel by applying a
minimum of 70 psig (4.8 bar/483kPa) to the“IN” port on the Drive
Housing.
4. Insert a 5/16” hexagonal wrench through the hole in the Motor
Housing Cover to engage the hexagonal recess at the rear of the
Rotor.
5. Manually, rotate the Rotor until the engine is cranked to its
desired position.
Gas Operated Starters
WARNING
When repairing a gas-operated starter or when converting a
starter from air operation to gas operation, it is necessary to use
Ingersoll-Rand No. MBA31 Plastic Gasket, as directed, and the
following procedures for assembly and testing must be explicitly
followed.
1. Apply a thin film of sealant to the Housing Cover End Plug and
the Lubricator Port Plug as they are assembled.
2. Plug the exhaust. Connect air line to the inlet, regulate the air
pressure to 40 psig (2.8 bar/280 kPa) and immerse the unit for
30 seconds in light oil, or non-flammable solvent. If there are
any bubbles, the unit is unfit for gas operation. Tighten where
necessary and/or apply sealant to area showing leak. Retest.

The performance of the Starter is dependent on the pressure at the inlet of the starter.
This pressure is eected by the pressure drop between the Air Receiver Tank and the Starter.
The most signicant pressure drops will occur in ttings (Valves, Tees, Elbows, etc.)
The next signicant source of pressure drop is the hose. The following table provides
recommended hose and Starter Relay Valves (SRV) sizes for typical one starter installations.
Systems with many ttings or long hose should be analyzed and sized individually.
For Gas Operation the exhaust outlet must be piped
away to a safe location.
For Natural Gas Operation, Piped Exhaust must be
used and Drive Housing vent plug replaced with
suitable hose which connects into piped exhaust
system.
For Air Applications a Muer or Splash Guard
Deector must be used.
