38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is an electromechanical replacement assembly that combines a two-speed drive motor and a drain pump designed for compatible Speed Queen washing machines. The kit supplies the primary mechanical drive for basket agitation and spin cycles while providing a dedicated pump mechanism too evacuate wash and rinse water; the 120V rating denotes standard single-phase line operation common to residential and light commercial units.
Within the appliance the motor portion provides two discrete operating speeds (typically a low-speed agitation and a high-speed spin) and couples to the transmission or gearcase and basket via a drive shaft and coupling. The pump portion mounts near the motor and engages with the washer’s drain plumbing to move water out of the tub during drain and spin phases.This assembly interfaces with the machine’s control/timer circuits,lid or door interlocks,motor start/run circuitry and the electrical supply; correct mechanical alignment,electrical connections,and compatibility with the washer’s control logic are required for reliable operation.
In this article you will find a technical examination of the kit’s function and typical applications, guidance on compatibility checks (voltage, mounting points, shaft and coupling dimensions, connector types and OEM part matching), common failure symptoms to expect (no agitation, no spin, pump not evacuating, motor humming, intermittent stops, overheating or odor indicating electrical distress), high-level troubleshooting considerations (electrical continuity and supply verification, inspection of the pump impeller and drive coupling, and checks for control signal presence), and practical replacement considerations such as matching specifications, harness orientation, mechanical fastening and safety precautions.The goal is to provide technicians,engineers and appliance owners with the context needed to assess suitability,diagnose faults,and plan a service or replacement without prescribing specific step-by-step repair procedures in this introduction.

Function and Role of the Washer Drive motor and Drain Pump Assembly
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines a two-speed drive motor and a matched drain pump to perform the core mechanical functions of a top-load washer: developing low-speed torque for agitation and high-speed torque for extraction, while providing positive water evacuation during drain cycles.The drive motor contains distinct windings and control inputs that select a low-speed (agitate) and a high-speed (spin) mode; switching is handled by the washer’s control system through relays or switches that energize the appropriate winding. The pump portion is a centrifugal impeller assembly coupled to the motor or motor-mounted gearbox, sized to move the typical wash volume and to tolerate lint and small debris; its operation is independent of the spin speed but must be synchronized by the control logic to run during drain and certain intermittent cycles.
- Primary behaviors: low-speed torque for agitation, high-speed torque for extraction, and positive drainage via the centrifugal impeller.
- Common symptoms of component failure: motor hums but does not turn, lack of spin, no drain or slow draining, unusual vibration or noise during spin.
- Installation considerations: confirm 120V supply, matching motor mounting pattern, shaft orientation and pulley/hub dimensions, and correct electrical connectors for control and ground.
- Service tip: test motor windings and pump impeller continuity before replacement; check for obstructions in the pump inlet and drain hose that can mimic motor failure.
Compatibility is determined by mechanical fit and electrical interface rather than cosmetic appearance; technicians should verify the mounting hole pattern,shaft length and diameter,connector types,and rated input (120 V AC) against the machine wiring diagram before installing the kit. In practice, replacing a worn assembly with an exact-fit kit reduces alignment and sealing issues-examples include swapping a worn clutch-driven motor for a direct-coupled unit with matching flange, or replacing a noisy pump impeller that was blocked by a sock and caused overheating. When diagnosing, use basic electrical checks (line voltage at the motor, continuity of windings) and inspect the pump housing for debris to distinguish between motor electrical faults and hydraulic restrictions.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V Integrates with the Transmission, Control Board, and Drain System
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V supplies two discrete operating speeds and an integral pump mounting that interfaces directly with the washer transmission, the control board, and the drain plumbing. The motor contains separate winding or tap points selected by the machine’s control logic to produce a low-torque wash/agitate speed and a higher-speed spin mode; the transmission couples that rotational input through a geartrain or clutch assembly to drive the agitator and basket. The drain pump in the kit is positioned and driven so the control board can energize it independently or concurrently with spin to evacuate water before or during high-speed operation,minimizing the need for separate drive components and simplifying the mechanical path between motor,transmission,and plumbing.
Compatibility and practical installation hinge on correct mechanical alignment, matched electrical connectors, and the control board’s output circuitry. Technicians should verify that the motor shaft orientation and mounting holes line up with the transmission coupler, confirm the harness pinout matches the washer’s board (low-speed, high-speed, neutral and pump feed), and route the pump outlet to the existing drain hose without excessive bends or height that impede flow.Common troubleshooting checks include measuring control-board output voltage to the appropriate winding during cycle transitions, confirming pump impeller freedom and inlet clearance, and inspecting the transmission coupling for wear if the motor runs but no torque is delivered to the gearcase.
- Mechanical interface: shaft coupling,mount alignment,and pump volute position
- Electrical interface: control-board relays/outputs for low/high motor windings and pump feed
- Plumbing interface: pump outlet,hose routing,and check-valve positioning
- Diagnostic checks: continuity of windings,voltage during cycles,and pump impeller integrity
| Item | Description |
|---|---|
| Transmission | Receives motor torque via a shaft/coupler; geartrain or clutch converts speed for agitation and spin. |
| Control board | Selects motor windings for low/high speed and energizes the pump circuit at the correct cycle stages. |
| Drain pump | Mounted to the motor assembly or adjacent housing; electrically driven to evacuate tub water during drain/spin. |
Common Failure Symptoms: Electrical, Mechanical, Drainage, and Performance Indicators
The 38034P Speed Queen 38034P Washer Motor & Pump kit 2-Speed 120V functions as a matched drive and drain assembly: the motor provides two discrete shaft speeds for agitation and spin, while the pump evacuates wash water. Electrical symptoms that indicate motor issues include a persistent hum with no rotation, tripped breakers or blown fuses, intermittent speed selection, excessive inrush or running current, and burning smells that suggest winding insulation failure. Mechanical indications include loud grinding or rumbling (bearing or rotor contact), shaft seizure, worn brush holders or commutator wear, and misalignment of the pump coupling. Drainage and performance indicators frequently enough overlap-slow or incomplete draining, stubborn wet loads after spin, or water backing into the tub typically point to a clogged or damaged pump impeller, collapsed hose, or an electrical failure that prevents the pump from receiving full voltage. Verify compatibility of the replacement assembly with the washer’s mounting points, connector harness, and speed-selection wiring before installation.
- No rotation but motor hums: electrical start circuit fault or mechanical seizure.
- High current draw and overheating: bearing failure or winding short.
- Intermittent speeds or no spin/agitate: selector switch, internal windings, or control wiring problem.
- Poor draining or pump noise: foreign object in impeller,pump wear,or collapsed drain hose.
| Item | Description |
|---|---|
| No spin, motor hums | Start circuit open or rotor locked; check line voltage, selector continuity, and for mechanical obstruction at the pump coupling. |
| Excessive vibration/noise | Worn bearings or damaged rotor; inspect for axial play and rough rotation under hand-turning (power removed). |
| Pump runs but no flow | Impeller damaged or inlet blocked; remove pump and inspect for debris or fractured vanes. |
For practical diagnosis use a multimeter and clamp ammeter to measure line voltage at the motor terminals, continuity of the speed-selector circuits, and running current versus the motor nameplate. If the motor draws higher-than-specified current while stalled or under load, suspect mechanical binding or a shorted winding; if the motor runs but the washer does not agitate or spin at the correct speed, isolate the selector switch and control wiring. For drainage faults, disconnect the pump and perform a bench test: apply 120V only to the pump circuit to confirm impeller rotation and inspect the housing for obstructions. When replacing components, ensure the 2-speed, 120V electrical configuration and mechanical mounting of the replacement match the original to avoid mismatches that can cause repeated failures.
Compatibility, Replacement Considerations, and diagnostic/Installation Procedures for Field Service Technicians
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a matched drive and pump assembly that supplies two discrete motor speeds and the drain pumping function for compatible Speed Queen top-load washers. Functionally, the motor will present separate speed terminals or winding taps for high and low speed operation at 120 V while the pump is directly coupled to the motor output or via a short coupling; confirm shaft diameter, mounting hole pattern, and harness connector pinout against the machine’s service documentation before swapping units. Compatibility checks should include verifying harness color mapping and terminal labeling, confirming that the physical coupling and mounting bracket align with the washer frame, and ensuring the replacement does not introduce different control signals or safety interlocks than the original assembly.
- Visual inspection: seized rotor, damaged impeller, oil/water intrusion, and bearing wear.
- Electrical checks: verify 120 V supply at the motor, measure resistance between common and speed terminals, and test for insulation leakage or continuity to chassis.
- mechanical checks: free-spin rotor by hand, inspect coupling and belt alignment, and confirm impeller clearance.
- Functional verification: perform a no-load run,verify speed switching and pump priming,and run a drain/load cycle to confirm normal operation.
Field-service replacement should follow a controlled sequence: disconnect mains power,document or photograph connector pinouts,unbolt and remove the old assembly,transfer any retained mounting hardware,and install the new unit ensuring correct alignment and secure fasteners. For diagnostics, compare measured winding resistances with the removed unit or service literature and use an insulation tester to detect leakage; an open winding or vastly different resistance indicates motor winding failure, while continuity to chassis suggests internal shorting. After installation, verify high and low speed operation, observe pump flow and drain time, and listen for bearing noise or vibration; persistent symptoms after replacement typically point to control/timer issues, wiring faults, or plumbing restrictions rather than the motor/pump assembly itself.

Q&A
What is the Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V used for and which machines does it fit?
the 38034P is an OEM replacement motor-and-pump kit designed for many Speed Queen top‑load washers that use a 2‑speed, 120V drive motor (agitate and spin speeds). Compatibility depends on your washer model and production year – always verify the part number against your machine’s model and serial number or consult Speed Queen/parts retailer compatibility lists before ordering.
What symptoms indicate I need to replace the motor or pump?
Common signs include: washer won’t agitate or spin, motor hums but shaft does not turn, washer won’t drain, loud grinding or squealing noises during operation, burning smell or smoke, and visible leaks from the pump housing. Any of these symptoms can indicate a failing motor, seized bearings, a clogged/jammed pump impeller, or internal electrical failure.
How can I test whether the motor or pump is bad?
Always disconnect power first. For the motor: inspect for burned smell/visible damage, try to turn the rotor by hand (it should rotate freely), and use a multimeter to check continuity across the windings (you should see continuity, not an open circuit). If the motor only hums, the start mechanism or bearings may be failing. For the pump: remove debris/obstructions,check that the impeller turns freely,and verify the pump receives 120V at the appropriate cycle. If the pump receives voltage but does not run, it is indeed likely bad and should be replaced.
Does the kit include everything I need to replace both parts?
Most 38034P kits include the motor, pump assembly, and common mounting hardware (gaskets, bolts, etc.), but exact contents vary by seller. Confirm the item description or ask the supplier to verify what’s included. You may need to reuse or replace ancillary items such as drive couplers, belts, or hose clamps depending on wear.
Can I replace the two‑speed 120V motor with a single‑speed or different voltage motor?
No. You must replace the motor with a unit that matches the original specifications: 2‑speed and 120V for proper agitate and spin functions and for electrical compatibility. Using a single‑speed or different voltage motor will prevent normal operation, may damage controls, and is a safety/electrical hazard.
What wiring or connector issues should I watch for during installation?
Before disconnecting wires, label or photograph the wiring and connectors so you can restore them correctly. Two‑speed motors typically have separate speed leads plus a common/neutral. Make sure connectors are clean, correctly seated, and match the original harness.Replace any frayed wires or corroded terminals. Follow the wiring diagram on the machine or the motor; if in doubt,consult a service manual or a technician.
How difficult is the installation and what tools do I need?
Difficulty is moderate. Basic mechanical skills and hand tools are required: screwdrivers, nut drivers/sockets, pliers, possibly a pulley puller, and a multimeter for electrical checks. you’ll need to remove the cabinet or access panel,drain the washer,disconnect water and electrical connections,and remount the motor/pump.Typical replacement time for a competent DIYer is 1-3 hours. If you’re not comfortable with electrical wiring or heavy parts, hire a qualified appliance technician.
After installing the kit the washer still won’t drain or spin – what should I check next?
Verify the following: correct wiring and secure connectors,that the pump impeller and hoses are free of blockages,lid/tub switches and other interlocks are functioning,drive components (clutch,belt,or coupler) are intact,and the control/timer is sending voltage to the motor/pump during the cycle. Also recheck that the motor grounding is secure. If voltage is present but the new motor/pump do not run,return the kit under warranty or contact a technician for further diagnosis.
