Identify AirCoat 423 Air Motor Parts by Diagram Callout
Use the Titan AirCoat 423 Air Motor Assembly exploded diagram to locate the cylinder, piston, piston rod, trip mechanism, toggle components, valve poppets, O-rings, seals, motor base, covers, grounding hardware, coupling pin, and 0533924 motor service kit.
How the AirCoat 423 Air Motor Produces Pump Motion
The Titan AirCoat 423 Air Motor Assembly converts regulated compressed air into reciprocating mechanical movement that drives the fluid pump. Its cylinder, piston, piston rod, motor base, trip rod, valve actuator, toggle mechanism, valve stems, and poppets work together to reverse airflow automatically at the end of each stroke.
Compressed air acts on the piston inside Titan 0533366 air motor cylinder. The piston and Titan 0533385 piston rod travel through the motor base while the trip rod, yoke, actuator, toggle arms, rockers, springs, and pins shift the inlet and exhaust valves. This alternating valve action changes which side of the piston receives pressure and keeps the motor cycling.
The AirCoat 423 uses Titan 0533382 piston, 0533379 trip rod, 0533372 valve actuator, 0533373 trip rod yoke, 0533369 toggle rockers, 0533370 springs, 0533371 toggle arms, and 0533375 toggle pins. Precise condition and adjustment of these parts are critical to reliable stroke reversal.
Sealing components include Titan 0533365, 0533378, and 0533388 O-rings plus Titan 0533387 flat seal. Valve service components include lockwires, adjusting nuts, valve poppets, grommets, spring clips, and valve stem poppet assemblies. Worn seals can cause air leakage or power loss, while worn trip and valve parts can cause stalling, hesitation, or failure to reverse.
Titan 0533391 is the AirCoat 423 motor base, while 0533505 and 0533507 are the front and rear covers. Titan 0533509 grounding wire and 0533510 ground screw maintain the motor’s grounding connection. Titan 0533441 is the coupling pin connecting the air-motor piston rod to the fluid-pump displacement rod.
Additional verified AirCoat 423 air-motor service parts include Titan 0533367 lockwire, 0533368 adjusting nut, 0533376 valve poppet, 0533377 grommet, and 0533128 valve stem poppet/valve stem assembly.
Titan 0533924 is the AirCoat 423 motor service kit. It includes the listed lockwires, adjusting nuts, valve poppets, grommets, spring clips, valve-stem poppet assemblies, O-rings, flat seal, and coupling pin. Components outside the kit should be inspected individually and replaced when worn or damaged.

How to Find the Correct Air Motor Part
Follow this sequence before ordering or opening the motor.
Verify air supply
Confirm adequate clean, regulated, lubricated compressed air reaches the motor.
Identify the symptom
Separate stalling, leakage, weak power, knocking, and coupling faults.
Match the callout
Record the exact diagram item, Titan number, and required quantity.
Check kit coverage
Confirm whether 0533924 includes the failed part or whether it must be ordered separately.
Maintenance Practices That Protect the Air Motor
- Maintain clean, dry, correctly regulated, and properly lubricated compressed air.
- Relieve all air and fluid pressure before accessing the motor.
- Inspect the coupling pin and rod connection during pump service.
- Check cylinder walls, piston, piston rod, and seals for scoring or wear.
- Replace lockwires rather than reusing previously bent pieces.
- Keep the grounding wire and ground screw secure.
Build a Complete AirCoat 423 Air Motor Repair Plan
For reversal problems, inspect the trip rod, yoke, actuator, toggle pins, arms, rockers, springs, valve stems, poppets, adjusting nuts, grommets, spring clips, and lockwires as one system.
For leakage or weak power, inspect the piston O-ring, motor-base O-rings, flat seal, piston, cylinder wall, piston rod, air preparation, exhaust path, and mounting alignment. Replace all required service-kit wear parts during a complete rebuild.
