Streamlining and modernizing service gear
and pinion product offering.
AXIB-9507
8/95
Effective August 1, 1995, Spicer will initiate a program to streamline and modernize the service gear and pinion product offer-
ing. This program is intended to replace or eliminate all gearsets with “square” pinion splines and improve compatibility with
current production gearing. The benefits of the program are:
• Continued service for Spicer axles. With the addition of the appropriate end yoke, virtually all single and tandem rear axles
produced since the late 1970’s as well as tandem axles produced after 1980 will remain serviceable at the component level
indefinitely. Spicer Axle products also remain serviceable at the unit level through “hybrid” offerings of the Carrier Exchange
Program. These are brand-new Spicer carrier assemblies equipped with side gears that adapt to them to older style axle
shaft configurations.
• Improved product performance. The gearing eliminated by the program often reflects design criteria no longer used in pro
duction axles. Newer style gearing meets the most current standard for durability and quiet operation. Involute pinion splines
offer better performance under impact loads. Pinion nuts reflect the best available clamping technology.
• Simplified inventory management: The new gearset product line is highly standardized, drastically simplifying the task of
stocking the product needed to service a wide variety of Spicer products. In some cases, a single new part number replaces
as many as three older part numbers.
The following tables provide a crossover from older gear and pinion kit to current replacement. In most cases, the substitute
gearsets fit directly into the older carrier and require no additional parts other than a new end yoke to return the unit to service.
Where necessary, new kits have been developed containing other parts needed to adapt newer gearing to older axle models.
Gear and pinion kits also contain printed instruction sheets outlining the process.
Installation of new-style gearing in some older carriers also affects standout by as much as 1/2-inch. This may require the user
to adjust driveline length prior to reinstallation. Minor variations in final drive ratio may also be required in some cases.
