ARO 94742 Motor Body | ARO Pump Maintenance Replacement Part 94742

ARO 94742 Motor Body

The ARO 94742 is a replacement pump component intended for maintenance, repair or overhaul work on compatible ARO pump assemblies. It should be selected by exact part number and verified against the pump's complete model because visually similar components can differ by size, material, thread, geometry or assembly position.

For maintenance teams, the main value of ordering by ARO part number 94742 is traceability. Matching the documented part number to the pump manual helps reduce incorrect substitutions and gives technicians a clear reference when planning a repair.

Cast Iron Motor Body for Pump Service

The available product data identifies the material as Cast Iron. Material selection matters because dimensions, sealing behavior, corrosion resistance and service environment can vary between pump configurations.

This component is associated with pump maintenance and repair. During replacement, avoid assuming that another part with a similar appearance is interchangeable. A small dimensional or material difference may affect assembly fit, sealing, alignment or service life.

Compatibility and Model Verification

The row does not provide a definitive pump-series mapping, so compatibility should be confirmed from the complete ARO pump model and the corresponding parts manual.

Before purchasing, compare the full pump model, product configuration and parts-list callout with the current ARO documentation. This is especially important for pumps that share a common frame size but use different wetted materials, air-section options, connection standards or service kits.

Maintenance and Inspection Guidance

When replacing the ARO 94742 Motor Body, inspect the mating components, fasteners, seals and surrounding wear surfaces. Look for wear, distortion, corrosion, scoring, damaged threads, looseness, contamination or other conditions that could prevent the new part from seating and operating correctly.

If surrounding components are also worn, replacing only one item may not fully resolve the maintenance issue. Review the exploded parts diagram and identify whether related seals, hardware or service-kit components should be renewed at the same time.

Installation Considerations

• Confirm the exact ARO part number 94742 before disassembly.
• Compare the removed component with the replacement before installation.
• Clean mating surfaces and remove debris that could affect fit or sealing.
• Use the torque, orientation and lubrication instructions specified in the pump service manual.
• Do not force components that do not align naturally with the documented assembly.
• After service, perform the recommended inspection and operational checks before returning the pump to duty.

Ordering ARO 94742

For an accurate maintenance order, provide the supplier with the ARO part number 94742, the complete pump model and the required quantity. If the repair involves several related components, compare the individual parts with the applicable ARO service kit to determine which option best matches the planned maintenance scope.

Using the exact manufacturer part reference, rather than selecting only by appearance or general description, helps maintenance teams obtain the correct Motor Body and supports a more efficient pump repair process.
