150BMPE88R53 Air Starter Motor for Caterpillar

The 150BMPE88R53 is a vane air starting motor for Caterpillar engines and engine systems. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The starter motor uses compressed air as the operating medium and transfers rotational movement to the engine through its starter pinion. The supplied application data identifies the compatible equipment brand as Caterpillar; specific Caterpillar engine or machine model numbers are not provided.

The part is identified in the supplied product data as an Ingersoll Rand air starter motor with right-hand rotation, a maximum operating pressure of 150 PSI, a 12-tooth pinion with 8/10P pitch, and an SAE 03 mounting flange.

Specifications

The vane configuration denotes the internal operating design of the pneumatic motor. During starting, compressed air acts on the internal vanes and produces rotation of the drive assembly; the 12-tooth pinion then engages the engine flywheel ring gear.

The right-hand rotation specification refers to the direction of pinion rotation during operation. The rotation direction, pinion tooth profile, tooth pitch, and SAE 03 flange are installation parameters that must correspond to the Caterpillar engine starting arrangement.

The stated 150 PSI value is the maximum pressure listed for operation of this starter motor. No additional dimensions, weight, connection-thread data, included components, or specific Caterpillar model applications are provided in the available product information.
