The service notesare defined as:“NOTE”: Provides additional instructions or proceduresto complete tasks and make sure that the axle/componentsfunction properly.Indicates a hazardous situation or unsafe practice that, if not avoided, could result in equipment damageand serious injury.Ridewell-branded axles have a serial identification tag attached to the axle tube (body) listing theBase Axle Part Number (165xxxx). The part numbers of the brake and wheel end equipment componentsconnected to the base axle can be found by locating the Base Axle Part Number in the chart, then searchingfor the component on the page number(s) referenced.Contact Ridewell Customer Service if you have a base axle part number that is not listed in the chart.Part 5005916500611650062165006316500641650069- 500941650096- 1650097- 165009816500991650100165010116501021650103- 1650104- 1650105- 1650106- 2-1312-1310-1112-1312-1310-1110-1110-1110-11Part Number1650107- 1650108- 50140165014116501461650148- 5018116501821650185- 5Part Number16501881650192- 16501931650196- 1650201- 1650205165020616502071650213165021416502151650216- 50258165025916502601650264- Part 514-1514-1514-15( ) Custom cam length needed - Contact Ridewell Customer ServiceENGPage 2Trailer Axle-Parts-Guide-RevG-09-10-19Trailer Axle-Parts-Guide-RevG-09-10-19Page 3ENG
Dressed-Axle ConfigurationPart Numbers (164xxxx)Dressed-Axle Part No. (164-)Item DescriptionsAir Disc Brake(p. 24; 26; 30; 32)Parallel SpindleTapered SpindleAxle BodyAxle Body(p 24)} (p 26)OuterBearing(p30)(p 32)InnerBearingTrack (Axle Track)The distance between the centerline of two wheels mountedon each axle end. The theoretical centerline of a dual steelwheel configuration is used for the axle track specification.16.5” x 7.0”Drum Brake(pp . 10-17)Camber (Optional)Axle camber is defined as the inward or outward angle of tiresmounted on the axle. Positive camber means the top of thetires are farther apart than the bottom. Axles are camberedso that there is a bow in the axle. Weight is put on the axle tobring the wheel camber to zero. All cambered axles should bemounted with the center bow up.ABS PrepHow wheel end components are prepared to accept an AntiLock Braking System.1. Wheel hub is prepared without an installed tone ring.2. Hub prep with installed tone ring3. Both the tone ring and ABS sensor are installed.Spindle Type - WallThe spindle is the part of the axle endthat supports the wheel end components.The spindle is either parallel to the axlebody or tapered towards the axle end.Wall(thickness) affects axle load capacity - athicker wall has a higher capacity.Brake RatingThe maximum stopping power of thebrake. Brake rating is dependent on thedrum or disc brake type and size, the typeof brake pad/shoe lining, the brake inputpower, the brake’s structural rating andthe tire static load radius. Brake inputpower for cam/disc brakes includes airchamber size and slack adjuster length.Brake Rating must not be over- orunder-sized for the suspension application. Confirm application with Ridewell.Standard Trailer Dimensions12.25” x 7.5”Drum Brake(p.18)Trailer suspensions are designed to fit up onto standard I-beam trailer frames at the beam centers thatcorrespond to standard axle track widths (Figure 4).Installation at wider beam centers will reduce suspension clearances. Installation at narrower beam centers will de-rate the axle beam capacity.NOTE: For other, non-standard beam centers, frames, frame centers, axle track widths and wheel-endequipment, the suspension installer is responsible for verifying clearances, axle capacity, proper fit-up,and any additional required suspension support structure.StandardConfigurationsFigure 3.The 11-digit Dressed-Axle Configuration Part Number (164xxxxxxxx) provides a reference for either astandard (5-inch) or a 5 3/4-inch Large Diameter Axle (LDA) configured with a drum or disc brake.ENGPage 4Trailer Axle-Parts-Guide-RevG-09-10-19Dual WheelWide-Base WheelZero �77.5”83.5”Trailer �50”Beam Air SpringCenter Center35”31”41”37”47”43”Page 5Figure 4.Beam Centers - The center line-tocenter line distance from one trailingarm beam to the other.ENG
Wheel-End EquipmentThe rotating components on the endof an axle including the wheel hub,wheel bearing cups and cones,the hub seal, the hubcap and relatedequipment such as tire pressurecontrol systems are consideredwheel-end equipment.Brake drums/rotors are fastenedto the wheel hub. Tire/wheelassemblies are fastenedto the hub withstuds and nuts.5-inch Axle (Standard)TrackWidth(Inches)71.5”Hub SealA seal installed into the inboard side of the wheel hub to retaingrease or oil and prevent external contamination from enteringthe interior hub cavity.77.5”Hubcap Gasket/SealA thin, flat seal or O-ring installed between the hubcap and theoutboard face of the hub that prevents lubricant from leakingout of the hub and contaminants from entering the hub.Dust ShieldA thin sheet of metal bolted in place behind the rotor to protect from rocks, grit, and other debris found on the road. Thereare two types - rotor shields and brake-pad shields.TrackWidth(Inches)71.5”ABS Tone Ring (Exciter ring)A notched ring (80-100 equally spaced slots) attached to awheel hub or behind a brake rotor that is read by an ABSspeed sensor to determine the speed of an individual wheel.Hub-Piloted MountingA wheel mounting system in which a boss on the hub is usedto locate the center hole of a hub-piloted wheel. Flanged nutsare used to attach the wheel to the flat face of the wheel disc.Stud-Piloted MountingA wheel mounting system in which location and fastening ofthe wheel are both accomplished by nuts which fit corresponding studs at each wheel bolt hole.ENGPage 6Trailer 5-inch AxleLarge Diameter Axle (LDA)ABS (Anti-Lock Braking System)ABS system components include a toothed wheel (tone ring)mounted on the hub of each monitored wheel; an electronicsensor that has one end against the tooth wheel to monitor andtransmit wheel speed and a sensor clip that holds the sensor 534333231302944434241403938373635Tube Wall0.591”0.75”Axle BeamAxle BeamCapacityCapacityGAWR (lbs)GAWR 25323,10120,72822,53120,22921,98819,75321,471Tube Wall0.335”0.394”Axle Beam RatingGross Axle Weight Rating (GAWR)is a term used to specify the maximumload-carrying capacity of a single axle assembly.
