27155 Speed Queen Drive Belt is a continuous flexible power-transmission element used on âSpeed Queen laundry⣠equipment; it is the looped belt assembly⣠that transmits torque from the âelectric motor to the appliance’s tub, drumor transmission.As a⢠drive belt, it is indeed â˘typically constructed from a rubber compound with internal tensile cords and,â depending on the application, a specific cross-sectional⤠profile (V, poly-V/serpentineor flat) selected to match â¤pulley geometry â˘and load requirements.
In operation the drive belt couples the motor output â˘shaft to driven components, interactingâ directly with âmotor pulleys, idler or tensionerâ pulleysand the drum or â¤transmission pulley. Proper belt âselection and â˘installation control rotational speed, torque transfer and âŁbelt tensionand they affect⤠vibration, noiseand âwear on bearings and pulleys. â˘The belt’s condition and alignment also influence slip,transient⢠loads âonâ the motor,and the⣠overall mechanical efficiency and service âlifeâ of the drive train.
This article explains the 27155 belt’s functional role and typical technical specifications,â outlines âmodel- and size-compatibility â¤considerations, âdescribes commonâ failure symptoms âand diagnostic âŁchecks (including visual inspection,⣠tension and alignment assessmentand related component inspection)and summarizes âpractical â˘replacement considerations â˘such as verifying belt profile and length, assessing pulley and idler âconditionand following safe⣠service procedures. The goal âis to provide technicians, engineersand appliance âowners with the information needed to identifyâ compatibility, diagnose drive-belt issues,â and make informed âŁdecisions âduringâ troubleshooting and replacement.

Function and Role of the âDrive Belt in Speedâ Queen Washer MotorâTransmission Systems
The 27155 Speed â¤Queen Drive Belt transfers torque from the âelectric motor to the⣠washer transmission, converting the motor’s high-speed rotation⤠into the lower-speed, â˘high-torque motion ârequired for agitation and spin. In motorâtransmission systems⣠the belt ridesâ in pulley âgrooves on the⢠motor and transmission⣠inputâ shafts and is tensioned either by a fixed idlerâ or by the geometry⤠of the â˘motor mount. The belt’s construction and profile⢠determine âits engagement behavior: a ribbed/multiâgroove âŁor Vâprofile belt will seat âinto the pulley to minimize slip under ânormal loads, while the material and reinforcing fibers control stretch, wear resistanceand the belt’s âdamping of transient torque⣠spikes during load shifts⢠and spin-up events.
- Reduced spin âspeed or intermittent spinning underâ load (belt⣠slipping).
- Squealing or chirping noises at startup or during spin (glazing or improper seating).
- visible wear: frayed edges, âmissing âribsor cracking.
- Excessive looseness⤠after aâ short service âinterval (loss of⣠tension âor stretched belt).

| Example | Replace âwith a matched 27155⤠part number forâ models specified in the service manual |
Compatibility requires matching belt profile, effective lengthand recommended⢠material â˘so the belt fully engages pulley grooves âand achieves the correct preload. for practical servicing, inspect â¤pulleys â¤and⢠any idler â¤or motor mount for wear or misalignment before installing a new belt; replacing the belt without addressing a worn idler can lead to âŁrapid failure. Maintain correct tension andâ alignment ⣠during installation-too âlittle tension causes slip andâ overheating, too â˘much⣠tension increases âbearing loads-so verify⤠properâ operation with an unloaded â˘spin and a loaded cycle to confirm theâ beltâ sustains⤠torque without noise⤠or visible slip.
How⣠the 27155 Speed Queenâ Drive Belt Transfers âTorque Between âMotor Pulley â¤and transmission
The 27155 Speed Queen Driveâ Belt is the flexible âlink that directly transmits rotational force from the motor pulley to the transmission input. Torque transfer occurs by theâ belt wrapping around both â¤pulleys soâ tensile load in the belt’s reinforcement âcords carries the driving â˘force while friction between belt surface and pulley â˘grooves âŁprevents slip. The effective âtorqueâ transmitted depends on belt âŁtension,â the wrap angle on each pulley, the friction coefficient â˘of the belt/pulley interfaceand the pulley diameters; increasing tension â˘or wrap angleâ raises the transmissible torque until the belt or pulleys reach âthier mechanical âlimits.
In service,correct torque transfer requires the belt âŁto match the âpulley profile âand length,be free of glazing âor contamination,and be installed with proper alignment and tension. âA⣠mismatched âor⢠worn belt â¤canâ slip under peak loads,produce squeal,or âŁallow the tub or drumâ to rotate slower than motor RPM,which are practicalâ indicators of diminished torque â˘transfer. technicians should verify belt routing, check pulleys⤠for wear or buildupand replace with the âŁspecified âpart number to⢠restore the original tensioning andâ groove compatibility; â˘routine âinspection for cracks, frayingor âŁlossâ of âŁelasticity â˘helps maintain⢠consistent drive performance.
- Symptoms of impaired torque transfer: â squeal atâ start-up,â slipping under load, reducedâ spin speedor visible belt glazing.
- Installation checks: correct belt routing, âconsistent pulley⣠groove engagement,â and alignment to avoid edge loading.
- Compatibility âconsiderations: belt length, cord constructionand groove profile must match⣠the transmission and motor pulleys.
- Maintenance tip: âkeep pulleysâ clean and â˘replace belts âŁshowing loss of elasticity or âsurface cracking rather⤠thanâ re-tensioning repeatedly.

Common Failure Symptoms and Wear Patterns ofâ theâ 27155 Driveâ Belt: Slipping, Frayingand Stretch
The 27155 Speed⢠Queen Drive Belt transfers âtorque from âthe motor to the âŁtransmission⢠or drum âand its physical characteristics-cross-section profile, material compound, rib countâ and nominal length-determine how it behaves under load. Common failure modes are mechanical: slipping occurs⤠when the contact surface âbecomes glazed or oil-contaminated âŁor â¤when tension dropsâ below the design threshold; fraying and edge wear result from pulley misalignment, foreign-object abrasionor contact âwith sharp chassis features; stretch and permanent elongation develop â¤from repeated âthermal cycling and polymer creep, which reduce pre-tension and âŁchange âŁrunning geometry.â Proper âcompatibility⤠requires âŁmatchingâ the â˘belt’s profile and length to â˘the machine model and confirming the idler/tensioner and pulley faces are⤠serviceable, because a ânew 27155 belt installed on damaged âpulleys will⣠exhibit accelerated wear and unpredictable behavior.
- slipping/squealing â¤under âload – shiny or glazed belt surface, intermittent drum rotation.
- Fraying or strand separation at⣠edges â- visible fiberâ breakage or⢠ragged edges where⣠belt contacts a lip.
- Stretch/looseness â¤- increased belt deflection, loss of tensionor degraded â˘spin performance.
- Cracks or missingâ ribs – brittle fractures in the âbelt material, frequently enough atâ the inner ârib roots.
Diagnose by combining a â¤visual inspection with â¤a simple run-and-feel test: inspect rib profiles for⣠cracking, glazingor missing â¤material; check âŁpulley faces for scoring or burrs and verify alignment;⣠and compare the belt’s free length and deflection against service⢠specifications orâ a known-good belt. If glazing or oil contamination is present, cleaning pulleysâ and replacing the belt is the usual remedy âŁbecause resurfacing rarely restores full friction. Use the tableâ below as a âswift checklist during âa service call to correlate observed symptoms with likely causes â¤and inspectionâ actions.

Replacement Considerations, model Compatibilityandâ StepâbyâStep Installation procedures
The 27155⢠Speed Queen Drive Belt transmits torque from the motor âto the transmission/drum assembly and is a primary determinant of drive efficiency, noiseand slip behavior. Effective âŁoperation depends on correct belt profile, tensionand âŁpulleyâ alignment: visible⤠glazing, fraying, âor stretching reduces friction and âcausesâ slipping⣠under load, while â¤oil or lubricant contamination⣠accelerates degradation.Technicians should evaluate pulley concentricity and bearing play before installing âa⤠new belt,⢠because replacing âthe belt alone â¤when⣠pulleys âŁor idlers⣠are âworn typically leads to rapid reâfailure or â˘persistent vibration âand noise.
Compatibility is defined âŁby⣠the belt’s effective length and crossâsection rather â˘than byâ superficial model identifiers, so confirm the washer is a beltâdrive variant and match the OEM part number or a measured circumference before ordering a replacement. When servicing,replace ancillary wear items (idler âpulley,tension spring,motor mount fasteners) as needed and verify belt routing and tension against the machine’s service diagram; a correct⢠installationâ willâ seat the ribs in the pulley grooves,allow smooth handârotation⢠of âŁthe drum,and pass a shortâ diagnostic cycle without slippage⢠or excessive temperature rise.
- Disconnect power, remove access panelsand document current belt routing before disassembly.
- Release the⢠tensioner âŁor idler, removeâ the old beltand inspect pulleys, bearings, seals,⢠and adjacent components for wear or âcontamination.
- Installâ the new belt â¤on transmission and â¤motor pulleys, engage the âtensioner, align⣠ribs to groovesand rotate the drumâ by hand to check tracking.
- Reassemble panels and run a lowâload test cycle âwhile observing for noise, slipor abnormal â¤vibration; recheck tension after the initial run.
