Power Your Repairs With Genuine MultiFinish 440 Drive Assembly Parts
Shop replacement components for the Titan MultiFinish 440 Drive Assembly, including the main housing, slider, second-stage gear, thrust washer, crankshaft and gear assembly, motor, capacitor, cooling fan, motor baffle, brush kit, and mounting hardware. Use the exploded assembly drawing, item number, and exact Titan part number to identify the correct component before ordering.
What the MultiFinish 440 Drive Assembly Contains
The drive assembly contains the components that transfer electric-motor rotation into the reciprocating motion required by the pump. The diagram includes the 805-204A main housing, 0508208 slider assembly, 704-176 second-stage gear, 704-174 thrust washer, 704-173A crankshaft and gear assembly, 0558373A motor replacement assembly, capacitor components, motor baffle, cooling fan, wire connector, motor brush kit, and related fasteners.
Because the motor, gears, crankshaft, slider, housing, capacitor, brushes, and cooling components operate together, one worn part can create symptoms elsewhere in the drive. Grinding may originate at the gears or thrust surfaces, binding may involve slider alignment, and intermittent motor operation may involve brushes, wiring, or the capacitor. Inspect the complete drive path before selecting parts.
Functions Supported by the Drive Assembly
- Transfers motor torque through the second-stage gear and crankshaft assembly.
- Converts rotational movement into the reciprocating motion that operates the pump.
- Supports and aligns moving components through the main housing, slider, and thrust washer.
- Assists reliable motor starting and operation through the capacitor and brush components.
- Directs cooling airflow and secures drive components with the fan, baffle, screws, and wiring hardware.
When Contractors Use This Parts Diagram
- Grinding, knocking, vibration, or abnormal gearbox-noise diagnosis.
- Jerky, binding, or incomplete pump-stroke repair.
- Motor replacement after confirmed winding, armature, or structural motor failure.
- Brush, capacitor, fan, baffle, housing, gear, washer, and mounting-hardware service.
- Drive-section refurbishment for contractor, rental-fleet, and repair-shop equipment.
Common MultiFinish 440 Drive Assembly Symptoms
Use symptoms as a starting point, then inspect the related system and verify the exact replacement part through the assembly diagram.
High-Value MultiFinish 440 Drive Assembly Parts
These motor, housing, slider, gear, crankshaft, and brush components represent major drive-section repairs. Verify the diagram callout and exact part number before purchase.
Titan 0558373A Motor Replacement Assembly
The principal electric motor replacement for restoring rotational power after confirmed internal motor failure.
Titan 805-204A Main Housing Assembly
The main structural housing supports alignment of the motor, gear train, slider, and connected drive components.
Titan 0508208 Slider Assembly
The slider transfers crankshaft movement toward the pump and should move smoothly without binding or excessive wear.
Titan 704-173A Crankshaft/Gear Assembly
The crankshaft/gear assembly transforms rotational force from the motor into the linear motion needed to drive the pump piston, creating high pressure for airless spraying..
Titan 704-176 Second-Stage Gear
The second-stage gear is a major torque-transfer component that should be inspected for chipped teeth, scoring, looseness, and abnormal wear.
Titan 805-272 Motor Brush Kit
The motor brush kit restores electrical contact at the motor and should be inspected when operation becomes intermittent, weak, or unreliable.
How to Order the Correct MultiFinish 440 Drive Assembly Part
Follow this sequence to reduce fitment mistakes and avoid replacing parts that are not responsible for the operating problem.
Record the drive symptom
Identify whether the concern involves fluid pressure, air delivery, electrical response, leakage, noise, mounting, or visible damage.
Verify model and revision
Confirm the Titan MultiFinish 440 identification and note any serial or revision information available on the equipment label.
Match the callout
Use the drive assembly illustration to match the numbered callout with the corresponding Titan part number.
Inspect the complete drive path
Check wiring, hoses, seals, mounting hardware, connectors, filters, and mating components before completing the repair order.
Maintenance Practices That Protect the Drive Assembly
- Relieve fluid pressure and disconnect electrical power before inspection or service.
- Keep covers installed and clean to reduce dust, overspray, and debris entry.
- Inspect siphon and bypass hoses for cracks, restrictions, loose connections, or coating buildup.
- Check wiring, grounds, switches, circuit protection, and connectors for heat or physical damage.
- Monitor gauge behavior and investigate sudden changes before continued operation.
- Avoid operating the pump without material supply or with a restricted intake path.
- Inspect mating components together whenever a major assembly is removed.
Build a More Complete MultiFinish 440 Drive Assembly Repair
Major drive repairs should include an inspection of every component connected to the failed part. When replacing the motor, inspect the brushes, capacitor, fan, baffle, wiring, mounting screws, housing, and mechanical load. When replacing a gear or crankshaft component, inspect the mating teeth, thrust washer, slider, lubrication points, and housing alignment.
Electrical drive repairs should include the capacitor, motor brushes, wire connections, motor leads, grounding points, cooling fan, and baffle. Replacing one failed component while leaving a damaged connector, worn mating gear, binding slider, or obstructed cooling path in service can cause repeat failure.
