Description

What does a crankshaft flange do?

This crankshaft flange serves as a critical component in the air brake compressor assembly, facilitating the necessary mechanical connection to transfer rotary motion. Engineered with high-strength components, it ensures the stability and durability required during the compression stroke in heavy commercial vehicle applications.

Engine compatibility and fitment

The component is specifically compatible with Cummins engines, including X12, QSB, QSX15, ISX, ISB6.7, ISX15, ISB, QSC8.3, 6BT5.9, QSB6.7, QSL9, and ISC8.3 engines. This flange is an essential part for maintaining optimal performance in the compressor's moving assembly.

Installation and maintenance guidance

For workshop technicians performing compressor overhauls, inspecting the flange during crankshaft repair is vital to prevent air pressure loss. Ensuring a secure fitment during installation helps maintain the integrity of the entire pneumatic system and prevents premature wear of connected bearings or seals.

Troubleshooting and system integrity

Consult your authorized distributor for precise fitment verification.
