38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined electric motor and drain pump assembly intended for compatible Speed Queen washing machines. The assembly pairs a two‑speed,120 VAC drive motor with a centrifugal pump (and associated mounting and electrical connections) to provide both the mechanical drive required for agitation and spin and the fluid handling required for draining the wash tub.
Inside the appliance the motor delivers torque to the transmission or direct‑drive coupling at two selectable speeds-typically a lower speed for agitation and a higher speed for spin-while the pump evacuates wash and rinse water through the drain plumbing. Electrically the component interfaces with the machine control/timer or main PCB, motor relays or switches, and safety interlocks (lid switch/door lock and thermal protection); mechanically it mates to the transmission, tub, and drain system. Understanding these electrical and mechanical interfaces is notable for diagnosing cycle failures, noise, or drainage issues and for ensuring correct installation and alignment during service.
This article will explain the kit’s functional design and key specifications, outline compatible machine families and how to verify fitment, describe common failure symptoms (for example: no agitation, no spin, failure to drain, abnormal noise, motor humming or overheating), and provide systematic troubleshooting and diagnostic checks a technician can perform (electrical checks, continuity and insulation testing, pump impeller inspection, and mechanical coupling verification). It will also cover practical replacement considerations such as part‑number matching, connector and mount compatibility, required clearances and orientation, and basic safety precautions to observe during removal and installation.

Function and Role of the 2‑Speed Motor and Pump Assembly in Wash Cycle Drive,Agitation,and Drain Operations
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V integrates a two‑speed electric motor with a matched drain pump so a single replacement assembly handles agitation,spin drive,and draining on compatible Speed Queen models. The motor provides a low‑speed, high‑torque mode used to drive the agitator and saturate the load, and a high‑speed mode used to drive the spin/extraction stage; the pump is either driven directly from the motor shaft or mounted to the motor housing so drain operation is coordinated by the machine control. Technicians should verify mounting pattern, shaft length, connector type and wiring color codes against the machine’s schematic before installation to ensure mechanical and electrical compatibility with the washer’s transmission and control circuits.
During a wash cycle the controller selects the motor’s low‑speed winding to produce the slow, reversible motion required for agitation; switching to the high‑speed winding increases shaft RPM to develop centrifugal force for water extraction. Drain operations are initiated by the control and either energize the pump (if it has a separate electrical feed) or rely on the motor to turn the pump impeller through its drive coupling. Common diagnostic checks include verifying line voltage to the appropriate motor lead during each cycle stage, checking for obstructed pump impellers or hoses when drain fails, and confirming that the motor changes winding selection when the control signals transition between wash and spin. Practical features and checks:
- Low speed: high torque for agitation and gentle reversals.
- High speed: rapid shaft rotation for water extraction.
- Pump: impeller-driven drain; inspect for debris, leaks, and proper coupling.
- Compatibility checks: mounting, shaft profile, plug/wire colors, and 120V supply.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2‑Speed 120V Operates Within the Washer’s Drive, Coupling, and drain Systems
The 38034P Speed Queen 38034P Washer Motor & pump Kit 2‑Speed 120V replaces the combined motor and drain pump assembly that provides both low-speed agitation and high-speed spin while supplying the pump flow required for tub evacuation. The kit’s two-speed motor changes the active winding or drive selection under control of the washer’s timer or electronic control to present distinct torque and RPM characteristics to the drive train; that rotational output is transmitted to the transmission or tub via a flexible spline or rubber coupling. The pump is mounted to the motor assembly and is driven by the motor shaft or an integrated drive link to move water from the tub to the drain during the drain cycle.
In service, the motor, coupling, and pump act as an integrated subsystem: the motor provides the mechanical energy, the coupling transfers that energy while protecting the transmission from shock, and the pump converts shaft rotation into fluid flow for draining. Compatibility considerations include matching shaft orientation, spline count, mounting hole pattern, and the 120V two‑speed electrical connections; improper alignment of the coupling or incorrect pump orientation can produce no-drive or poor-drain symptoms. For practical troubleshooting and installation, confirm correct connector placement, verify that the coupling engages the transmission splines fully, and run a drain and spin test to validate low-speed agitation, high-speed spin, and pump evacuation under load.
- Speed behavior: low speed for agitation, high speed for spin-selected by the washer control.
- Coupling role: flexible torque transfer and sacrificial failure point protecting the gearbox.
- pump behavior: impeller-driven evacuation mounted to motor assembly, orientation affects flow and sealing.
- Compatibility checks: shaft spline, mounting pattern, 120V wiring, and physical clearance in the chassis.

Common Failure Symptoms: Electrical, Mechanical, and Hydraulic Indicators of 38034P Motor and Pump Faults
The 38034P Speed queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined motor and pump assembly used to provide both agitation/spin torque and drainage flow; electrical failures typically present as a motor that does not start, a persistent hum without shaft rotation, intermittent operation between speeds, or tripping the house breaker. These symptoms usually stem from open or shorted winding circuits, deteriorated commutator/brush contact, failed internal thermal protection, or poor supply connections at the motor harness. Technicians should verify correct line voltage at the motor leads, check winding continuity and insulation resistance, and inspect the motor endbells for brush wear or commutator pitting before replacing the entire kit, since several fault modes can be repaired or isolated at the connection level without swapping the assembly.
Mechanical and hydraulic indicators more frequently enough point to the pump or the motor bearings and shaft coupling: reduced drain rate, gurgling or grinding noises, visible leaks at the pump housing, or excessive shaft play indicate impeller damage, foreign-object blockage, or bearing failure. Practical checks include removing the pump cover to inspect and clear the impeller, turning the motor shaft by hand to feel for roughness or axial play, and observing pump flow while the motor is powered at each speed (watching for the expected increase in RPM-related flow). The list below summarizes common symptoms and quick diagnostic steps to help determine whether the fault is electrical, mechanical, or hydraulic.
- No start, loud hum: Check supply voltage and motor winding continuity; a humming motor with no rotation often indicates seized bearings or heavy commutator drag.
- Intermittent speed change or no high/low: Verify switch contacts and harness continuity between speed taps; worn commutator or brush lift can cause inconsistent speed selection.
- Poor or no drain: Inspect pump impeller for blockage, damaged vanes, or disconnected discharge hose.
- Grinding or squeal: Rotate shaft manually to detect bearing failure or imbalanced impeller with trapped debris.
- Tripped breaker or burnt smell: Measure motor current under load; high current suggests shorted windings or mechanical binding.
| Item | Description |

| Voltage | 120 V AC supply; confirm correct phase and neutral at motor connector |
| Speeds | Two discrete speed taps for agitation vs. spin; verify continuity to both taps |
| Common faults | Open/short windings,brush/commutator wear,bearing failure,impeller blockage or leaks |
| Quick tests | Measure line voltage and winding resistance,inspect impeller,check shaft for play,and run-loaded current draw |
Replacement Considerations and Installation Procedures: Compatibility,Wiring,Torque,and Calibration for 38034P Motor & Pump Kits
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined replacement assembly that must be evaluated for mechanical and electrical compatibility before installation. Verify the kit’s flange pattern, shaft diameter and length, and pump coupling style against the original components to ensure correct engagement; mismatched shaft length or coupling type can prevent proper pump priming and cause premature wear. The motor contains two speed windings or taps for high and low agitation/spin functions, so confirm that the washer’s selector/timer wiring and physical mount orientation match the replacement kit – some Speed Queen frames and control assemblies require different mounting brackets or harness adapters even when the electrical ratings are identical.
- Confirm part number and mechanical fit (flange, shaft, coupling)
- Label and document all wiring before removal
- Measure supply voltage and continuity with a multimeter
- Use a calibrated torque wrench for mounting hardware
- Perform a no-load bench/run test and full-cycle verification
| Item | Description |
|---|---|
| Compatibility | Match part number, mounting pattern, shaft/coupling and voltage rating to the original unit. |
| Wiring | Identify common, high/low speed taps and ground per wiring diagram; confirm 120 V supply and continuity. |
| Torque | Tighten mounting hardware to the manufacturer’s specified torque using a calibrated wrench to prevent distortion or misalignment. |
| Calibration | Bench-run and in-machine tests to verify speed selection, rotation direction and pump flow; adjust alignment and re-torque as required. |
During installation, de-energize the machine and document all original wire connections; use a meter to confirm the lead functions and to locate the common and the two speed taps. After mechanical mounting, hand-rotate the shaft to ensure the pump impeller and coupling clearances are correct, then tighten fasteners incrementally and to published specifications - if specifications are not available, use a torque value appropriate for the fastener size and materials and recheck alignment. Before returning the washer to service, verify correct rotation and speed selection with a tachometer or by observing basket spin and extraction performance under a controlled test cycle, and confirm the pump primes and discharges correctly without leaks or abnormal noise.
Q&A
What exactly is the 38034P Speed Queen Washer Motor & Pump Kit?
The 38034P kit is a replacement assembly that contains a 2‑speed 120V drive motor and the matching drain pump intended for certain Speed Queen top‑load washers. The two speeds provide a low/agitate speed and a high/spin speed; the pump handles draining. Kits often include mounting hardware and gaskets, but you should verify the exact contents with the seller before purchase.
How do the two motor speeds function and which speed does what?
A 2‑speed washer motor is designed so one (low) speed provides the slower oscillation/agitation cycle and the other (high) speed provides the fast spin cycle for water extraction. The washer’s timer or electronic control selects the appropriate winding/speed for each phase of the wash cycle.
Which models of speed Queen washers will this part fit?
Compatibility varies by model and production year. The 38034P is made as an OEM replacement for a range of Speed Queen top‑load machines, but you must confirm fitment by checking your washer’s model/serial number against the supplier’s compatibility list or speed Queen parts lookup. Don’t rely on body appearance alone-mounting, shaft length, and electrical connectors must match.
What are common symptoms that indicate the motor or pump needs replacement?
Typical symptoms for motor problems: washer hums but won’t spin or agitate, no rotation, intermittent operation, or burning odors/smoke. Typical pump problems: washer drains slowly, does not drain at all, or leaks from the pump. Because some symptoms overlap (e.g., a stalled pump can make the motor strain), inspect the pump for clogs and remove drive belts/clutch to isolate whether the motor shaft turns freely before replacing the motor.
How should I test the motor and pump before replacing them?
Start with safety: unplug the washer and shut off water. For the pump, check for debris in the inlet/outlet and try turning the impeller by hand (when safe/disconnected).For the motor,check for obvious mechanical seizures (shaft not turning) and listen for humming when powered (indicates starting issue). Use a multimeter to check for continuity of windings (compare to service manual specs) and check any start/run capacitor if the motor uses one.If you’re not comfortable with electrical testing, get a technician to diagnose.
Can I replace only the motor or only the pump, or do I need the whole kit?
Many suppliers sell the motor and pump individually; however, the kit is offered for convenience and ensures matched parts. If only one component is confirmed faulty (pump clothed, motor runs), you can replace only that piece-provided the replacement matches your machine’s mounting, shaft length, and electrical connections.
Is installation something a homeowner can do, and what safety/tools are required?
A competent DIYer can often install this kit, but it requires basic mechanical and electrical skills. Always disconnect power and water first. Typical tools: socket/ratchet set,screwdrivers,pliers,multimeter,bucket for water,and possibly a service manual or wiring photo for reassembly. Take pictures of wiring before disconnection. If the motor is heavy or the tub must be supported/suspended, get help or call a technician.
are there any important considerations after installation (settings, testing, warranty)?
After installation, check for correct rotation, secure mounting, proper belt/clutch alignment (if applicable), and that the pump has no leaks. Run a short wash and drain/spin cycle to verify operation. Check the seller or Speed Queen for warranty coverage and retain receipts and part numbers in case of issues. If the washer still malfunctions, recheck wiring and control components rather than assuming the new parts are bad.
