GENUINE SPICER SER VICE PARTS

Should an axle assembly require replacement component parts, it is recommended that Spicer Heavy Axle Service Parts be used. Spicer Heavy Axle Service Parts are manufactured under the same rigid specification as are original equipment axle components. This assures the customer who uses genuine Spicer service parts, maximum reliability for a Spicer Heavy Axle assembly. They may be obtained through your vehicle manufacturer.

The use of non-original Spicer service parts may cause premature component failure and may void the warranty.

The items included in this book are currently being offered as service parts at the time of printing. The part numbers and illustrations are provided specifically for reference purposes only. Therefore, Spicer reserves the right to update this manual without notice or liability.

All axle assemblies are identified with two tags. One located on the differential carrier, and the other located on the right hand side of the axle housing. Two types of tags may be found on the axle, an aluminum tag that is riveted on the assembly or a coated mylar tag.

AXLE LUBRICANT RECOMMENDA TIONS

To ensure proper lubrication and operating temperature, correct lubricants and lubricant levels must be obtained.

RECOMMENDED LUBRICANTS

Mineral or Synthetic based hypoid gear lubricants that meet or exceed military specification MIL-L-2105D, and API service classification GL-5, are the minimum requirements for use in Spicer medium and heavy duty drive axles.

The table below indicates which SAE viscosities are recommended for various temperature ranges the vehicle will encounter.

SUBMERSION OR DEEP WATER FORDING

In the event the axle assembly should become

submerged in water, particularly if over the vent or breather, it is recommended that the lubricant be drained and all parts be inspected for water damage and/or contamination. Reassemble the carrier to the housing and refill with specifed gear lubricant.

AFTER OVERHAUL OR CHANGE INTERVALS

Fill the axle assembly to the bottom of housing fill hole as shown in the illustration below. It is recommended that following an overhaul, each side of the axle be jacked up seperately to approximately six inches and held into position for one minute. This procedure will allow adequate lubricant to flow into the wheel ends and help eliminate the possibility of premature damage to wheel bearings and seals. Lower the vehicle to the floor and allow ten minutes for lube to return to normal level. Check and refill assembly to bottom of fill hole to replace the lubricant that was directed into the wheel ends.

Ambient Air Temperature

SERVICE

Recommended lubricant change intervals are dependent on the application and operating environment. The following chart should be used to establish proper change intervals.

* Severe service includes any applications operating at

** Includes Semi-Synthetic blends that meet

MIL-L-2105D specifications.

NOTE: Lubricant close enough to the bottom of the fill hole to be seen or touched is not sufficient. Lubricant must be level with the fill hole.

GENERAL AXLE DESCRIPTION

IMPORTANT

ANY SERVICE PROCEDURES

This manual covers maintenance and rebuild procedures for the Spicer J340-S, J380-S, J400-S, W440-S and W460-S rear drive tandem axle assemblies.

Accordingly, anyone who uses a service procedure or tool different than shown must insure that their safety, and the vehicle's safety, will not be jeopardized by the service method selected.

The Spicer heavy duty single reduction rear drive axle is a full floating axle assembly, with a hypoid gear carrier assembly,

END YOKES AND FLANGES

using a High Strength Low Alloy (HSLA) steel axle housing. The hypoid pinion is straddle mounted with two tapered roller bearings behind the pinion teeth for thrust and radial loads. A pilot bearing is located on the nose of the pinion for radial load. The differential itself uses four precision forged pinion mate gears, a forged cross, and precision forged side gears.

bearing bores or misalign yoke lugs and result in early failures of journal needle bearings or other driveline components. Serious damage can also be done internally to the ring and pinion set or pinion bearings by hammering on external parts. End yokes or companion flanges should be removed or installed using the recommended methods outlined in this manual.

Safety glasses should be worn at all times when assembling or disassembling axles.

CLEANLINESS

Axle components should be steam cleaned prior to removal from the vehicle. Dirt is abrasive and will cause premature wear of otherwise serviceable parts. Service personnel should use a wash tank for thorough cleaning of parts just prior to assembly.

CAUTION: Hammering on end yokes can close in the

SAFETY PRECAUTIONS

Proper service and repair of vehicle components is important to the safe and reliable operation of all motor vehicles. This applies particularly to driving axles such as the ones described in this manual. The procedures recommended and described in this manual are tested, effective methods for performing service operations. Follow each procedure closely, making use of both the text and illustrations. Some of these service procedures show the use of certain tools designed specifically for the operation being performed. They are shown as a preferred means of performing the operation. It is not practical to anticipate and advise the service trade of all possible alternative methods, and of all possible hazardous consequences that could occur.
