LUBRICANT DESCRIPTION A multi-purpose, hypoid gear lubricant which con- forms to the following specifications should be used. t Hypoid Gear Lubricant conforms to all of these specifications. • The lubricant should have MIL–L–2105C and API GL 5 quality specifications. • Lubricant is a thermally stable SAE 80W–90 gear lubricant. • Lubricant for axles intended for heavy-duty or trailer tow use is SAE 75W–140 SYNTHETIC gear Trac-lok differentials require the addition of 3.5 oz. of friction modifier to the axle lubricant. The 194 RBI CAUTION: If axle is submerged in water, lubricant STANDARD DIFFERENTIAL DESCRIPTION The differential gear system divides the torque between the axle shafts. It allows the axle shafts to Each differential side gear is splined to an axle shaft. The pinion gears are mounted on a pinion OPERATION In operation, power flow occurs as follows: • The ring gear (bolted to the differential case) rotates the case • The differential pinion gears (mounted on the pinion mate shaft in the case) rotate the side gears • The side gears (splined to the axle shafts) rotate the shafts During straight-ahead driving, the differential pin- ion gears do not rotate on the pinion mate shaft. This When turning corners, the outside wheel must travel a greater distance than the inside wheel to TRAC-LOK Y DIFFERENTIAL DESCRIPTION In a standard differential, if one wheel spins, the opposite wheel will generate only as much torque as Fig. 1 Shim Locations 1 – PINION GEAR DEPTH SHIM Fig. 2 Differential Operation—Straight Ahead Driving 1 – IN STRAIGHT AHEAD DRIVING EACH WHEEL ROTATES AT 100% OF CASE SPEED 2 – PINION GEAR 3 - 66 194 RBI AXLE XJ DESCRIPTION AND OPERATION (Continued) |
