22358797 Apm Assy -440 — Volvo FMX FE Series trucks — FH400

This APM (Air Processing Module) Assy is a sophisticated unit that manages air pressure and moisture within the vehicle's air system, crucial for the reliable operation of brakes and other air-powered components. Built to precise engineering standards, it offers superior moisture removal and pressure regulation compared to a worn unit that may allow water into the system or fail to maintain correct pressure. Operators might observe air leaks, erratic brake application, or system pressure warnings when this module is malfunctioning.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of an APM issue may be the presence of water or oil in the air system, or a noticeable drop in air pressure. If not addressed, this can lead to freezing of air lines in cold weather or corrosion of air system components, potentially causing brake failure. Continued operation risks damage to the air compressor and other critical air-dependent systems.

Installation Tip

Ensure all air lines are correctly labeled and reconnected to their proper ports on the new APM to prevent air leaks. Do not force connections; they should fit smoothly if aligned correctly.

Service Note

Inspect the air dryer cartridge and check all air tanks for water accumulation when replacing the APM Assy.
