38034P speed Queen 38034P Washer Motor & pump Kit 2-Speed 120V is a combined electric drive motor and drain pump assembly for Speed Queen washing machines; it is a two-speed, 120-volt alternating-current motor paired with a water evacuation pump and mounting hardware, supplied as a service replacement component. As a hardware element,the kit replaces the rotating drive element that provides mechanical torque for the wash and spin cycles and the pump that removes wash and rinse water from the tub.
Within the appliance the motor provides discrete low- and high-speed outputs used by the transmission or direct-drive coupling to produce agitation and high-speed spin, while the pump clears water from the wash tub through the drain plumbing. Electrically the assembly interfaces with the washer’s control/timer, motor start/selection circuit, lid and pressure switches, and overcurrent/thermal protection; mechanically it interfaces with the transmission or coupling, pump mounting flange, drain hose, and chassis mounts. Proper operation therefore depends on correct voltage, wiring connections, mechanical alignment, and functional control signals from the machine’s control system.
This article will explain the kit’s functional role, key electrical and mechanical specifications to check for compatibility, common failure symptoms to recognize (for example: no agitation or spin, motor hum, failure to drain, leakage or abnormal noise), systematic troubleshooting steps for isolating motor versus pump faults, and practical replacement considerations such as matching voltage, mounting orientation, shaft and coupling dimensions, connector types, and necessary safety procedures before service. The intent is to provide technicians, engineers, and experienced appliance owners with technical context and actionable guidance for diagnosis and correct replacement of the component.

Functional role and electrical and mechanical specifications of the washer drive motor and pump assembly
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V provides the primary mechanical drive for both the agitation and spin cycles and includes the pump assembly responsible for draining the tub.The two‑speed, single‑phase 120 V AC motor is configured to deliver a high‑torque, low‑speed mode for agitation and a low‑torque, high‑speed mode for spin extraction; speed selection is achieved by switching the motor windings or control signals to alter the effective winding configuration. The pump is driven directly from the motor output (either through an integral pump housing or a shaft coupling depending on the specific model) and uses a centrifugal impeller to evacuate water. When assessing compatibility, confirm matching electrical ratings, mounting footprint, shaft diameter, and connector pinout so the replacement integrates with the washer’s control and mechanical interfaces without requiring modification.
Electrically, expect a nominal rating of 120 V AC at 60 Hz with two distinct operating points; the motor’s nameplate on the original assembly provides the precise current and speed values for your request and should be used for load and circuit protection sizing. Mechanically, key characteristics include flange mounting orientation, shaft length and diameter, and the pump inlet/outlet positions – these determine clearance and hose routing.Common failure modes that technicians encounter are mechanical binding or debris in the pump impeller (reduced drain flow), worn bearings or bushings (noise and increased current draw), and control/wiring faults that prevent speed switching (motor runs only in one mode or hums without turning). For installation and troubleshooting, verify secure mounting bolts, correct wiring to the washer’s control board or timer, proper seal and gasket seating on the pump, and that the motor is not thermally damaged from previous overloads.
- Functions: low‑speed agitation, high‑speed spin, and centrifugal pump drainage.
- Compatibility checks: voltage,mounting pattern,shaft size,and connector pinout.
- Common symptoms: no agitation, no drain, excessive noise, or motor humming under load.
- Installation tips: inspect impeller clearance, verify wiring for two‑speed selection, and torque flange fasteners to specification.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V integrates with drive, pump, and control systems inside the appliance
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V couples to the washer’s drive and drain systems both mechanically and electrically to deliver the distinct agitation and spin functions. Mechanically, the motor’s output shaft engages the transmission or direct-drive interface via a splined shaft or coupling and uses the kit’s mounting flange and fasteners to align torque load paths; the pump portion of the kit mounts to a dedicated bracket or flange and is driven either directly from the motor output or from an adjacent pump shaft depending on the model.Electrically, the assembly expects a single-phase 120V supply and seperate control feeds for the low-speed and high-speed windings plus a switched feed for the drain pump; correct connector orientation, ground continuity, and matching harness pinouts are required for compatibility during replacement or service.
Control logic inside the appliance selects speeds and pump operation by routing mains voltage through timer contacts, relays, or the electronic control board to the appropriate winding or relay coil, and interlocks such as the lid switch, door lock, and thermal overload are placed in series to prevent unsafe operation. In practise this means a technician will see a distinct set of control signals: a low-speed feed during agitation, a high-speed feed during spin, and a pump feed during drain; failures such as a motor that hums without spinning, or a motor that runs but the tub does not drain, usually trace to faulty switching, connectors, the pump impeller, or a failed start/run winding. Common integration points and signals to verify during diagnosis include:
- Low-speed (agitate) feed – mains switched to low-speed winding
- High-speed (spin) feed – mains switched to high-speed winding or relay
- Pump run feed – separate switched mains to pump motor
- Safety interlocks – lid/door switch and thermal protection in series
- Mechanical interfaces - shaft spline, mounting bolt pattern, and pump flange orientation

common failure modes, observable symptoms, and diagnostic checks for motor and pump performance degradation
The 38034P speed Queen 38034P Washer Motor & Pump kit 2-Speed 120V combines a two-speed drive motor and drain pump; common failure modes fall into two categories: electrical degradation and mechanical wear. Electrical issues include winding insulation breakdown,intermittent connections at the speed-selection circuit,and increased running current caused by shorted turns or failing brushes/commutators (if the motor design uses brushes). Mechanical failures manifest as bearing wear,rotor rub,bent shafts,or a clogged/damaged pump impeller that increases torque load on the motor. In practice, an appliance with this kit may present symptoms such as slow or no agitation, failure to reach higher speed, loud bearing noise, humming with no rotation, tripping a house breaker, or persistent overheating; compatibility checks should confirm correct voltage, mounting orientation, shaft length, and connector pinout before installation to avoid misapplication-related failures.
Diagnostic checks focus on isolating electrical from mechanical causes and verifying that the motor and pump meet expected performance under load.Start with a visual inspection for oil/chemical contamination, impeller damage, and loose wiring; then use a multimeter and clamp ammeter to verify supply voltage at the motor terminals, winding continuity/resistance, and running current against expected ranges. Perform a no-load spin test to listen for bearings or rubbing and a locked-rotor current test to detect shorted turns; if the pump fails to move water but the motor runs, remove and inspect the impeller and check for obstructions or worn seals.Below is a concise list of observable symptoms and pragmatic diagnostic checks technicians typically use.
- Humming/no rotation – check supply voltage at motor, inspect start/run windings for continuity, and measure inrush/steady-state current.
- Reduced speed/torque - measure running amps versus expected, test speed-selection circuitry and connections for intermittent contacts.
- Loud grinding or vibration – perform a shaft spin test, inspect bearings and shaft coupling, and check motor mounting bolt integrity.
- No water pumping but motor runs – inspect pump impeller, housing for debris, and confirm pump coupling engagement.
- Overheating or tripping breakers – verify motor ventilation, check for excessive mechanical load, and compare current draw to specification.
| Item | Description |
|---|---|
| Nominal supply | 120 V AC single-phase – verify at motor terminals under load. |
| Speed selection | Two-speed motor – confirm correct wiring and continuity between speed windings during selection. |
| Common checks | Visual inspection, winding resistance, insulation resistance, clamp-ammeter current, and mechanical free-spin test. |
Replacement considerations, step-by-step installation procedure and post-installation verification testing for the motor & pump kit
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines the drive motor and drain pump into a matched assembly intended to restore both rotational drive and water evacuation functions. When selecting a replacement, confirm physical mounting dimensions, shaft diameter, and connector style against the washer model – mismatch in flange pattern or harness can prevent proper installation even if voltage and speed ratings match. Functionally, the two-speed motor provides distinct low-speed agitate and high-speed spin functions, while the pump must deliver adequate flow and pressure to clear the tub during drain cycles; common failure modes that justify replacement include seized bearings, excessive vibration from rotor wear, pump impeller damage, and electrical faults such as open windings or short-to-ground. For example, a machine that fills and agitates normally but fails to spin often points to speed-selection or mechanical coupling issues in the motor assembly rather than the pump, whereas persistent water remaining in the tub after spin indicates pump or hose obstruction and is resolved by a functioning pump in the kit.
The step-by-step installation requires mechanical alignment and basic electrical verification to ensure safe, reliable operation. Start by disconnecting power and documenting wire locations, then remove the cabinet and belt, unbolt the old motor/pump assembly, and transfer any pulleys or couplings that are not supplied with the kit; install the new kit with correct torque on motor mount fasteners, proper belt tension, and secure hose clamps. After reassembly, perform post-installation verification: confirm 120 V supply at the motor input with a multimeter, check continuity of windings and insulation to chassis, select both low and high speed cycles to verify rotor behavior and listen for abnormal noise, and run a drain test under loaded conditions (e.g., a wet towel) to confirm pump flow and absence of leaks. The checklist below highlights key verification steps technicians commonly use during commissioning.
- Disconnect power, label wiring, and photograph connector positions before disassembly.
- verify mechanical fit (mounting holes, shaft, pulley) and transfer any needed hardware.
- Reinstall with correct belt tension and secure ground connection.
- Electrical tests: supply voltage,winding continuity,and chassis insulation check.
- Operational tests: low-speed agitation,high-speed spin,and drain performance under load; inspect for leaks and abnormal vibration.

Q&A
Which Speed Queen washer models is the 38034P Motor & Pump Kit compatible with?
The 38034P kit is an OEM replacement intended for many Speed Queen top-load and commercial-style washers that use a 2-speed, 120 V motor and the matching pump assembly.Compatibility depends on the washer’s model and production date – always confirm compatibility by checking your washer model/tag and the part number cross-reference from Speed Queen or the parts supplier before purchasing.
What are the basic safety and preparation steps before installing this motor and pump kit?
Always unplug the washer or disconnect the circuit breaker, and shut off/ disconnect the water supply and relieve any water in the tub and hoses. Work on a dry,stable surface with the washer emptied of clothing. Wear eye protection and gloves. Take pictures of wiring and hose routing before disassembly so you can reassemble correctly. If you are not comfortable working with mains electricity or heavy components, hire a qualified technician.
do I need any special tools to install the kit, and how long does installation typically take?
Basic hand tools are usually sufficient: socket set, nut drivers, screwdrivers, pliers, and a multimeter for testing. You may also need a putty knife or trim tools to remove panels and a small container for water. A typical experienced technician can replace the motor and pump in 1-2 hours; a DIYer should allow more time (2-4 hours) depending on familiarity with the washer.
How do I wire the new motor correctly? Will I need to change any connections because it’s a 2-speed motor?
Match the new motor’s wiring to the original harness and the diagram on the washer or the motor nameplate. A 2-speed motor has separate windings/terminals for low (agitation) and high (spin) speeds and common power/neutral connections; the washer’s timer or switch selects the appropriate speed. Do not guess at wire colors – follow the wiring diagram and reconnect any grounding conductor. If the machine uses a capacitor, make sure it is connected per schematic and discharged before handling.
My washer hums but does not run after installing the kit – what should I check?
Common causes: a stalled pump (blocked or jammed impeller), seized motor bearings, a bad start/run capacitor, or incorrect wiring. First ensure nothing is obstructing the pump or tub, check for seized shafts by manually turning the pump/motor shaft (with power off), verify the capacitor and wiring with a multimeter, and check for a tripped thermal overload. If the motor still only hums, the motor might potentially be faulty and need replacement.
What noises should I expect from a properly functioning motor and pump,and what noises indicate a problem?
A normal motor/pump combination will produce a consistent low-level whir or hum during agitation and a stronger whir during spin and drain. Grinding, squealing, loud rattling, thumping, or intermittent clacking usually indicate problems: worn bearings, a failing pump impeller, foreign object in the pump, loose mounting hardware, or misaligned belt/drive components. Investigate and correct noisy conditions promptly to avoid further damage.
how do I troubleshoot a pump that won’t drain after installing the kit?
First, verify the pump is receiving power during the drain cycle (use a multimeter). If it has power but doesn’t turn,check for obstructions in the pump housing,hoses,or trap; remove debris from the impeller area. Inspect the pump impeller for damage and the pump coupling or drive connection for wear. If the pump makes a humming sound but does not turn, the impeller may be jammed or the pump motor may have failed and the pump assembly should be replaced.
Is it better to replace only the motor, only the pump, or the whole 38034P kit?
If both components show wear or are near end-of-life, replacing the whole kit (motor + pump) is recommended for reliability and to reduce repeat service calls. If diagnostics clearly point to a single failed component (such as,a pump jam with a perfectly good motor),replacing only the failed part can be cost-effective. Consider the age of the washer and the cost/warranty offered with the kit when deciding.
To Conclude
The 38034P Speed Queen 38034P Washer motor & Pump Kit 2-Speed 120V serves as a critical assembly in many top-load washing machines by providing both the drive motor and the pump needed for agitation, spin, and water removal.Its two-speed functionality supports distinct wash and spin cycles while the 120V specification matches standard household electrical systems, helping maintain reliable performance, proper cycle timing, and effective drainage-all essential to the washer’s overall operation and user experience.
Accurate diagnosis is critically important before replacing this kit: symptoms such as failure to spin, no drainage, unusual noises, intermittent operation, or overheating can have multiple causes, and replacing the motor and pump without confirming the root issue might potentially be unnecessary. A systematic inspection of electrical connections, controls, lid/latch switches, belts, hoses, and diagnostic tests on the motor and pump helps ensure the repair addresses the actual fault and avoids needless expense.
When diagnosis indicates that the motor and pump assembly is worn, damaged, or beyond repair, timely replacement with a compatible kit restores safe and efficient operation and can prevent secondary damage to other components. Proper installation-performed according to manufacturer guidance or by qualified service personnel-helps ensure correct fitment,electrical safety,and continued reliability,making replacement a pragmatic step when justified by a thorough assessment.
