285825 Whirlpoolâ Washer âAgitator Cam Repair Kitâ is âŁa replacement cam assembly designed to restore theâ mechanical interface between a washer’s drive system and its agitator. As a ârepair âŁkit rather thanâ an electronic module, it typically provides the cam geometry and â˘mounting features that locate and guide the agitator dogs or pawls and transmit drive forces from the âgearcase or⤠drive shaft to the agitator element.
Inside the appliance⣠the âagitator cam sits âat the⣠junction of the drive output (gearcase or direct-drive shaft) andâ the â¤agitator â¤column,⤠controlling engagementâ geometry, direction changes and âtheâ oneâway â˘or ratcheting action that produces the wash agitation cycleâ while allowing the agitatorâ to freewheel during spin.⢠It interacts directlyâ with splines, agitator dogs/pawls, fastenersâ and adjacent plastic components; its form, material andâ tolerances determine load distribution,⣠wear patterns⢠and noise â˘characteristics. Understanding the cam’s mechanical role helps explain common failure⤠modes such as⤠worn lobes or âbroken⣠engagement features, misalignmentâ with splinesand⢠secondary stress on the gearcase or agitator âŁassembly.
This article â¤will explain the function and operating principles âof the 285825 agitator cam, describe which âWhirlpool topâload models â¤and agitator types typically use itand â¤outline compatibility checks you should perform before â˘ordering a replacement.You â˘will â˘also find diagnostic indicators and âfailure symptoms to⣠watch for (for example slipping, âloss⣠of agitator motion, unusualâ noises âŁor â˘excessive play), stepâwise⢠troubleshooting checkpoints to isolate theâ camâ from related faultsand practical replacement considerations including inspection of⣠adjacent components, recommended fitment and⣠torque awarenessand common assembly issuesâ technicians and owners should anticipate.

Function âŁand Mechanical Role â˘of⢠the Agitator Cam âŁwithin Whirlpool Top-load Washers
The â¤agitator cam âconverts âthe rotational output of â˘the transmission into the alternating torque needed to oscillateâ a⣠two-piece âagitator; theâ replacement part frequently used for⢠this function⣠is the 285825 Whirlpool âWasher Agitator Cam â˘Repair âKit.In top-load âŁWhirlpool machines the cam sits between⤠the⣠transmission shaft and the⤠agitator⣠assembly,engaging splines and directional lobes to transmit drive in the âwash directionâ whileâ allowing relative freewheeling in the spin/drain direction. Compatibility depends on spline count,hubâ diameter,andâ the agitator dog design,so⤠technicians should confirm the cam part numberâ against the washer’s model andâ inspect mating surfacesâ for wear before installation.â The kit replaces the worn plastic cam surface that commonly fails under cyclic âŁshear âand⢠abrasion, restoring the intended engagement⢠geometry that controls agitation amplitude and timing.
The cam works together with agitator dogs, springsand the transmission â˘output to create one-way torque transfer: under load the â˘cam⣠ramps and locks to â˘move the agitator throughâ its strokeand⢠during the⢠opposite â¤motion it âallows the shaft to overrun.â Typical failure⤠modes are wear of the â¤cam lobes âor âbroken⤠retaining features, which produce symptoms such as slipping agitation, loud grinding âŁduring wash, âandâ excessive axial or rotational⤠play in the agitator. Practical âreplacement steps include removing⣠the⤠agitator to inspect spline condition, cleaning âmetal debris âŁfrom the hub, installing the new cam with correct orientation and seatingand âperforming a shortâ diagnostic⣠wash programâ to verify⤠engagement. Commonâ indicators and fast checks are listed⢠below.
- Agitator spins but does not oscillate – cam lobes or dogs worn.
- Grinding âor crunching noises during agitation – fractured cam or âdebris in hub.
- Excessive play orâ wobble of⤠the agitator – â˘lost âŁengagement or damaged splines.
- Intermittent âagitation⤠under load – partial cam failure or spring fatigue.

how the 285825 Whirlpool Washer âŁAgitator Cam Repair Kit âIntegrates with the Transmission and Agitator Assembly
The ⤠285825 Whirlpool Washer Agitator Camâ Repairâ Kit is a replacement cam that interfacesâ directly between the transmission âŁoutput shaft and the agitator internal dogs or splines to transfer torque and control the agitator’s oscillation. Mechanically, the cam seats on the transmission’s splined output and provides the stepped âsurfaces and detent geometry that engage the âŁagitator’s mating features; as the transmission⢠shiftsâ direction â¤and speed, âthe âcam⢠presents â˘the correct face⤠to⤠the agitator dogs so the agitator alternates between agitate and spin behavior. Compatibility dependsâ on matching â¤spline count, shaft diameterand agitator⣠design-verify those dimensions against âthe washer’s transmission and agitator components before installing âthe kit.
In operation âthe cam â˘functions as both a torque-transmission âelement and aâ timing âinterface: worn or fractured⤠cam faces will âallow âradial play, slippage⤠under load, âŁirregularâ agitationâ patternsand noise that localizesâ to the gearcase/agitator junction. During service, technicians⤠should inspect spline engagement, âcheck⢠for cracked teeth or deformed detentsand apply appropriate high-temperature grease to the mating surfaces; correct seating and â˘the retainingâ fastener torque are necessary to prevent the camâ from walking on the âoutputâ shaft. For example, a washer that fails to⢠agitate under heavy loads frequently enough shows rounded cam lobes or collapsed plastic detents, â¤which the â¤repair⣠kit replaces to restore proper mechanical indexing⤠between⢠the transmission and â˘agitator assembly.
- Common symptoms: slippage, intermittent agitation, grinding noise, âŁexcessiveâ play at agitator
- Pre-install checks: confirm⣠spline countâ andâ shaft diameter, â˘inspect⤠agitatorâ dogs for wear
- Service tips: clean mating âsurfaces, apply grease to splines, torque retaining nutâ to factory⣠spec

Diagnostic Failure Modes, Troubleshooting âSteps, â¤and Common âSymptoms of a â¤Worn âAgitatorâ Cam
The agitator camâ transmits intermittent clutching action between the transmission âand the agitator, converting continuous motor rotation into the back-and-forth motion â¤needed â¤for âeffective washing. The⢠285825 Whirlpool⤠Washer Agitator âCam Repair Kit contains the wear-prone cam and associatedâ components that restore proper⢠pawlâ engagement and âalignment withâ the agitator spline; replacing the cam re-establishes the intended mechanical interface rather than â˘modifying electronic or⣠control functions. Technically,â the cam âis a molded part that interfaces with both the âagitator assembly and the clutching mechanism inside the gearcase, soâ compatibility âshould⤠be confirmed âagainst the washer model âand agitator type⣠before installation toâ ensure⣠spline count, cam profileandâ mounting features match â˘the â˘original â¤part.
Typical failure modes include worn âor rounded âŁcam lobes, fracturedâ pawlsand â˘accelerated âabrasion from foreign debris;⤠thesâ manifest as slipping, erratic agitationor⣠complete loss â¤of oscillation while the basket still âspins. Troubleshooting follows a measured inspection: remove the âagitator cap, â¤check forâ plastic debris and⢠visible wear on the cam profile, verify âthere â¤is no âexcessive axial or radial freeplay at the agitator-spline interfaceand⢠run a short agitation-only cycle to reproduce the symptom. Common quick checks and symptoms are listed below to assist diagnosis:
- Agitator spins freely â˘but does⣠not rock back âand forth – indicates cam/pawl slip or stripped âlobes.
- Loud â¤clicking or grindingâ during agitation – suggests broken pawls or engagement against deformed surfaces.
- intermittent agitation that sometiems works -⤠wear causing partial engagement under load.
- Excessive vertical or⤠rotational play âŁat â˘the agitator⤠-⣠visual evidence of âŁworn splinesâ or cam seating.
- Clothing remains tangled or not cleaned evenly – â¤symptom âof reduced â¤agitation torque from cam slippage.

Compatibility, Required Componentsand Installation âConsiderations for Agitator Cam â˘Replacement
The 285825 Whirlpool Washer Agitator Cam⢠Repair Kit replaces the cam element⢠that converts â¤the transmission output’s rotation into the âŁagitator’s⢠back-and-forth â¤motion. âŁThe cam is a small, moldedâ component that âengages lugs orâ dogs⢠on the agitator base to allow directional reversal and âtimed locking during washâ cycles. when the cam or its mating bushing â˘wears, âŁthe agitator âmay âspin freely, âŁmake clicking noisesor⣠fail to reciprocate; diagnosing wear requires inspecting the cam surface, the agitator’s âengagement features, â˘and the âgearcase output for torn splines or fractured bosses. This kit⢠is âŁintended for Whirlpool top-load assemblies â¤that use âa â˘cam-style engagement;â techniciansâ should âconfirm the spline⢠count, mounting geometryand whetherâ a separate drive â˘block, clutchor agitator dogs⢠are⣠present âŁbefore assuming compatibility.
Installation requires basic hand tools and aâ systematic inspection of adjacent components as⤠a new cam alone⣠will not correct âdamage to the drive shaft, splinesor the agitator’s â˘internal dogs. Before reassembly, clean⢠mating surfaces, verify that the âŁcam seats flush on the output shaftand apply a thin film âŁof lubricant⣠if ârecommended by service literature; torque retaining fasteners to factory âspecifications âandâ verify free reciprocal motion with theâ agitator reinstalled. Typical installation and diagnosticâ checkpointsâ include:
- Check spline pattern and diameter against the replacement cam⤠to confirmâ fit.
- Inspect the drive block and âŁagitator dogs for cracking or deformation; replace if degraded.
- Verify that the transmission output shaft⤠and âsurrounding bosses are notâ stripped or scored.
- Perform a dry functional test (noâ water) to â˘confirm proper engagement⢠andâ direction changes before a full-load âtest.

Q&A
What is the 285825⤠whirlpool Washer Agitatorâ Cam â˘Repair kit?
The 285825 kit â˘is âa replacement agitator cam assembly usedâ in many Whirlpool (and some Kenmore/other âbrand) topâload washers. The cam is a plastic/nylonâ component that â˘engages the transmission/agitator shaft to convert the transmission’s motion into the backâandâforth agitation ofâ the âŁagitator. when the original cam is worn or broken the agitator can slip, clunk, âor fail to agitate properly.
What âŁsymptoms indicate the â¤cam needsâ toâ be⢠replaced?
Common signsâ of âa failing âŁagitator cam include: the agitator spinning freely with little resistance,intermittent or no â¤agitation during the washâ cycle,loud clicking or clunking noises⤠from the transmission/agitator area,or the⤠agitator⤠moving erratically (not switching betweenâ agitate and spin correctly). Visual inspection of âa removed agitator âfrequently enough âŁshows worn or â¤broken⣠cam âteeth or a cracked/flattened cam⣠surface.
Which washer models is part 285825 compatible with?
285825 fits a range⣠of Whirlpool topâload washers and some related models from âbrands sold by Whirlpool⤠(Kenmore,â estate, etc.). Compatibility varies â˘byâ model and production year, so always verify fitment by checkingâ your washer’s model number⣠against⣠the part listing on the manufacturer orâ authorized parts website. If you’re unsure,⢠provide the washer âmodelâ number to aâ parts⢠supplier for âconfirmation.
What components come in the repair kit?
A typical 285825 kit containsâ the replacement agitator cam and the necessary⢠mountingâ hardware (retainer/washer/bolt or â¤aâ cam retainer) required to⣠secure it. Exact contents⢠can vary by supplier or OEM vsâ aftermarketâ kit; checkâ the product description⣠to confirm what’s includedâ beforeâ purchasing.
how challenging is theâ installation and what tools doâ I need?
For someone â˘with basic âmechanical â¤skills â˘the replacement is usually moderate difficulty and typically takes 20-45 minutes. âŁTools commonly required include⢠a socket set (frequently enough â˘7/16″ or 1/2″), âŁa screwdriver orâ Torx â¤bitâ (depending on the â˘agitator cap), pliersand possibly a long âhex or 1/2″ driver to remove theâ agitator bolt. Always disconnect power and turn off water supplyâ before⤠starting. If the agitatorâ isâ corroded onto the shaft a puller or extra effort might potentially âŁbe needed.
Do I need to⢠remove the entire transmission or tub to replace the cam?
No.â In mostâ topâload models the cam is accessed by removing⤠the agitator (agitation assembly) only. The transmission/tub usually does not need to beâ removed.⢠You willâ remove the â¤agitator cap, take out the centerâ bolt, lift the agitator off the shaft, replace the cam, then reassemble. If internal transmission âdamage is present, further service may be necessary.
Are aftermarket 285825 âŁkits âŁas reliable â˘as OEM parts?
Aftermarket kits are frequently⢠enough lessâ expensive and can be satisfactory, but quality varies.OEM parts⢠from Whirlpool are designed to â˘match the original specifications and may last longer.If choosing aftermarket, buy from reputable suppliers and check reviews. Always⣠verify the kit fits your exact model andâ inspect the parts forâ robust construction before installation.
Any tips or troubleshooting after⣠replacement?
After installing the new â˘cam, run a short test washâ to confirm normal agitation and listen for unusual noises. If problems persist, â˘recheck that the âŁcam and agitator were seated correctly on the splines and that the center bolt/retainerâ is tight (secure butâ do not overtighten plastic parts).⤠If you âstill hear clunks or experience â¤slipping, inspect the agitator for internal âdamage and⢠the transmission coupling/shaft forâ wear – those components may also need repair âŁor replacement.
Theâ Way Forward
The 285825 â˘Whirlpool Washer Agitator⤠Cam repair Kit serves a focused role âin restoring proper agitator engagement and motion within compatible Whirlpool top-load washers. By replacing⣠wornâ or broken cam âcomponents, the kit helps reestablish correct mechanical⢠timing and⤠torque transfer between the motor⢠and agitator,⢠which⢠supports consistent wash performance and reduces the risk of further wear to adjacent drivetrain parts.
Accurate diagnosis and timely replacement are âcritically âimportant to ensure theâ repair addresses the root cause rather than a symptom. When symptoms such as irregular agitation, slippingor⣠unusual noise point to camâ wear orâ failure, â˘using the âcorrect replacement kit and following the manufacturer’s guidanceâ or aâ qualified technician’s instructions can be the most cost-effective way to restore reliable operation âŁand avoid more â˘extensive repairs.
