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.
