General Information
Introduction
Dana Commercial Vehicle Systems Division, presents this
publication to aid in maintenance and overhaul of Spicer
tandem drive axles.
Instructions contained cover the models listed. Their design is
similar, with primarily differences in load capacity. Capacity
variations are achieved by combining basic differential carrier
assemblies with different axle housings, axle shafts and wheel
equipment.
The suffix letter “P” in the model number indicates optional
lube pump. The pump is designed to provide additional lubrication
to the inter-axle differential and related parts.
