New Service Part Numbers:
Outlined below are the newly released service parts. Dealers should begin to maintain an initial level of these

design carriers will continue to be offered thru service.

LUBE PUMP, OUTPUT SHAFT SIDE GEARS AND LOOSE PARTS – Listed below are
the balance of the new individual service parts located in the power divider section of the forward
carrier. These parts are related directly to the new design lube pump system. Detailed parts and
illustrations are shown on page 3 of this bulletin.
IMPORTANT NOTE: The output shaft side gears are designed for use with specific input shafts, i.e. pump design vs. non
pump design. Do not to mix these parts. Use pump model output shafts with pump model input shafts as well as non pump
output shaft side gear with non pump input shafts!
Mixed parts will assemble together, but they are not designed to run
together and failure will occur if any parts are mixed.

SERVICE CARRIERS – The service carriers are completely interchangeable as a unit but the
components inside are not. Knowing the design level being serviced is very important when ordering
replacement parts for any repairs or overhauls. New Service Carrier part numbers have been
released so customers can take advantage of the new design. The old design service carriers will be
phased out. Refer to pages 4-6 of this bulletin for a complete crossover listing of carrier part
numbers.
Original design service carriers are completely
interchangeable with new design service carriers!
