Introduction Introduction Description Forward Tandem Axle The inter axle differential (IAD) is located behind the helical gear on the input shaft. The forward side gear of the inter axle differential is part of the upper helical gear hub. The thru shaft is splined to the rear side gear of the inter axle differential. Figure 2.1. OIL PUMP INPUT SHAFT HELICAL GEAR DRIVE PINION INTER AXLE DIFFERENTIAL The forward tandem axles anterior models 140, 145 and 160 . Use a single reduction, thru drive differential. The drive gearing is a two helical gear train and a hypoid ring gear and pinion. Bevel gears are used in the main differential and the inter axle differential. Figure 2.1 and Figure 2.2.

Optional Pressurized Lubrication System The anterior axles can be equipped with an optional pressurized lubrication system. This filtered system has an oil pump driven by the input shaft. The pump forces the lubricant for roller bearings of the axes of input and output and directly to the inter axle differential (IAD) Optional Driver-Controlled Main Differential Lock (DCDL) Both the forward and rear axles can be equipped with an optional driver-controlled main differential lock (DCDL). The differential lock is operated by an air-actuated shift unit located on the anterior axle differentisal. • When the differential lock is activated, the shift collar moves along the splines of the axle shaft toward the differential case. 8 MAINTENANCE MANUAL
