Introduction
Description
The 2-A-92 model is a two-speed auxilliary transmission, designed primarily for use with heavy-duty transmissions.
This transmission contains two sets of gears, thus giving the reduction (low) ratio when power is delivered through the two sets
of gears. The other speed is obtained by direct (high) drive through the auxiliary.
A single shift bar in the right side of the case controls the speed changes. When the shift bar is moved 7/8" forward from neutral,
the mainshaft sliding gear locks the mainshaft to the drive gear and shaft, thus delivering power directly through the transmission.
When the shift bar is moved 7/8" to the rear from neutral, the sliding clutch locks the mainshaft bushed gear to the mainshaft, thus
transferring power through the two sets of gears to obtain the reduction ratio.
The 2-A-92 has a solid countershaft with an integral low speed gear and a press-fit drive gear.

General Instructions for Disassembly
Important: Read this section before starting the detailed disassembly procedures.
It is assumed in the detailed disassembly instructions that the transmission has been removed from the chassis, the lubricant has
been drained, the parking brake removed, if so equipped, and both universal joint companion flanges have been removed.
Follow each procedure closely in each section, making use of both the text and pictures. Use certain precautions, as listed below,
during disassembly.
Cleanliness
• Provide a clean place to work. It is important that no dirt or foreign material enters the unit during repairs. The outside
of the unit should be carefully cleaned before starting the disassembly. Dirt is abrasive and can damage highly polished
parts such as bearings, sleeves, and bushings.
Bearings
• Carefully wash and re-lubricate all bearings as removed and protectively wrap until ready for use. Remove all bearings
with pullers designed for this purpose. Do not remove bearings with hammer and punch.
When Driving
• Apply force to shafts, bearings, and housings with restraint. Movement of some parts is restricted. Do not apply force
after the part being driven stops solidly. Use soft hammers, soft bars, and mauls for all disassembly work.

Inspection and General Instructions for Reassembly
Before reassembling the transmission, the individual parts should be carefully checked to eliminate those damaged from previous
service. This inspection procedure should be carefully followed to insure the maximum of wear life from the rebuilt unit.
The cost of a new part is generally a small fraction of the total cost of downtime and labor, should the use of a questionable part
make additional repairs necessary before the next regularly scheduled overhaul.
Recommended inspection procedures are set forth in the check list which follows:
Bearings
• Wash all bearings in clean solvent. Check balls, rolls, and races for pits and spalled areas. Check the bearing shields for
damage. Replace bearings which are pitted, spalled, or damaged.
• Lubricate bearings and check for axial and radial clearances. Replace the bearings with excessive clearances.
• Check fits of the bearings in the case bores. If the outer races turn freely in the bores, the case should be replaced.
Gears
• Check the operating gear teeth for pitting on the tooth faces. Gears with pitted teeth should be replaced.
• Check all engaging gear teeth both internal and external. Gears with teeth worn, tapered, or reduced in length from clashing in shifting should be relpaced.
• Check the radial clearance of the bushed gear. If excessive radial clearance is found, replace the bushing.
Splines
• Check the splines on all the shafts for wear. If sliding gears or companion flanges have worn into the sides of the splines,
shafts, or gears they should be replaced.
Gray Iron Parts
• Check all gray iron parts for cracks and breaks. Replace or repair parts found to be damaged. Heavy castings may be
welded or brazed providing the cracks do not extend into the bearing bores or bolting surfaces.
Washers
• Check the surfaces of the washers. Washers scored or reduced in thickness should be replaced.
Shifting Bar Assembly
• Check the yoke for alignment and straighten if sprung.
• Check the lockscrew in the yoke and tighten and rewire if found loose.
• Check the neutral notches of the shifting bar for wear from the tension spring ball.
• Check yoke for wear at pads and replace if worn.
• Check yoke for excessive wear and replace if worn.
Bearing Covers
• Check the covers for wear from the thrust of adjacent bearing. Replace the covers that are worn or grooved from the
thrust of the bearing outer race.
• Check bores of covers for wear and replace those worn oversize.
Oil Seals
• Check the lip seal in the front and rear for wear, cracks, or breaks. Check the tension of the lip on the sealed surface.
Replace seals if the lip is damaged or shows no wiping action from the lip due to a lack of tension.

Assembly and Installation
General Instructions for Reassembly
Make sure the interior of the case and the other housings are clean. It is important that dirt be kept out of the transmission during
reassembly. Dirt is abrasive and can damage polished surfaces of sleeves, bushings, and bearings. Use certain precautions, as
listed below, during reassembly.
Gaskets
• Use new gaskets throughout the transmission as it is being rebuilt. Make sure all gaskets are installed. Omission of gaskets can result in oil leakage or improper stack-up of bearing covers. Seat gasket on part to be installed with adhesive to
hold in place during installation.
Capscrews
• To prevent oil leakage, use adhesive sealant on all capscrews. See Torque Ratings chart on page 6 for recommended
torque applications.
Initial Lubrication
• Coat gear bushings, washers, and splines of mainshaft with Lubriplate during installation to provide initial lubrication,
thus preventing scoring and galling.
Bearings
• Use of flanged-end bearing drivers is recommended for installation of bearings. These drivers apply equal force to both
inner and outer races of the bearing, preventing damage to the balls along with maintaining the correct bearing aligment
with the shaft and bore. If a tubular or sleeve driver is used, apply force evenly to the inner race and drive through the
tubing of the correct diameter.
Assembly and Installation
Universal Joint Companion Flanges
• Make sure the companion flanges are pulled tightly into place with the retaining nuts. Failure to tighten the retaining nuts,
or omission of parts between flanges and bearings will premit the shafts to move axially, with resultant damage to the
pilot bearing, mainshaft, and drive gear.
• When installing the companion flanges, tighten the retaining nuts with 400-450 lbs. ft. of torque if elastic stop nut is used.
With slotted type nut, use 250 to 300 lbs. ft. of torque. Make sure the speedometer gear has been installed between the
rear flange and the bearing. If the speedometer gear is not used, a replacement spacer of the same width must be used.
Make sure the speedometer gear washer is installed between the speedometer gear and bearing.
Oil Filling
• Remember to fill the transmission with the correct amount of lubricant. Refer to TCMT-0021 for lubrication information.
Sliding Clutch
• Check yoke and yoke slot in sliding clutch for extreme wear or discoloration from heat.
• Check engaging teeth of sliding clutch for partial engagement pattern.
