Introduction
Purpose and Scope of Manual
This manual is designed to provide information necessary to service and repair the Fuller® transmissions listed on the front.
How to use this Manual
The service procedures have been divided into two sections: In-Vehicle Service Procedures and Transmission Overhaul Proce­dures—Bench Service. In-Vehicle Service Procedures contain procedures that can be performed while the transmission is still installed in the vehicle. Transmission Overhaul Procedures contain procedures that are performed after the transmission has been removed from the vehicle.
The procedure sections are laid out with a general heading at the top outside edge of each page followed by more specific headings and the procedures. To find the information you need in these sections, first go to the section that contains the procedure you need. Then look at the heading at the top and outside edge of each page until you find the one that contains the procedure you need.
Transmission Overhaul Procedures follow the general steps for complete disassembly and then assembly of the transmission.
Note: In some instances the transmission appearance may be different from the illustrations, but the procedure is the same.
Disassemble Precautions
It is assumed in the detailed assembly instructions that the lubricant has been drained from the transmission, the necessary link­age and vehicle air lines disconnected and the transmission has been removed from vehicle chassis. Removal of the gear shift lever housing assembly (or remote control assembly) is included in the detailed instructions (How to Remove the Gear Shift Le­ver). This assembly MUST be detached from the shift bar housing before the transmission can be removed.
General Information
Follow closely each procedure in the detailed instructions, make use of the text, illustrations, and photographs provided.
Assemblies
When disassembling the various assemblies, such as the mainshaft, countershafts, and shift bar housing, lay all parts
on a clean bench in the same sequence as removed. This procedure will simplify assembly and reduce the possibility of
losing parts.
Bearings
Carefully wash and lubricate all usable bearings as removed and protectively wrap until ready for use. Remove bearings
planned to be reused with pullers designed for this purpose.
Cleanliness
Provide a clean place to work. It is important that no dirt or foreign material enters the unit during repairs. Dirt is an
abrasive and can damage bearings. It is always a good practice to clean the outside of the unit before starting the planned
disassembly.
Input Shaft
The input shaft can be removed from the transmission without removing the countershafts, mainshaft, or main drive
gear. Special procedures are required and provided in this manual.
1
Introduction
Snap Rings
Remove snap rings with pliers designed for this purpose. Snap rings removed in this manner can be reused, if they are
not sprung or loose.
When Using Tools to Move Parts
Always apply force to shafts, housings, etc., with restraint. Movement of some parts is restricted. Never apply force to
driven parts after they stop solidly. The use of soft hammers, soft bars, and mauls for all disassembly work is recom-
mended.
Inspection Precautions
Before assembling the transmission, check each part carefully for abnormal or excessive wear and damage to determine reuse or replacement. When replacement is necessary, use only genuine Fuller extended life from your unit.
Since the cost of a new part is generally a small fraction of the total cost of downtime and labor, avoid reusing a questionable part which could lead to additional repairs and expense soon after assembly. To aid in determining the reuse or replacement of any transmission part, consideration should also be given to the unit's history, mileage, application, etc.
Recommended inspection procedures are provided in the following checklist.
Bearings
Wash all bearings in clean solvent. Check balls, rollers, and raceways for pitting, discoloration, and spalled areas. Re-
place bearings that are pitted, discolored, spalled, or damaged during disassembly.
Lubricate bearings that are not pitted, discolored, or spalled and check for axial and radial clearances.
Replace bearings with excessive clearances.
Check bearing fit. Bearing inner races should be tight to shaft; outer races slightly tight to slightly loose in case bore. If
the bearing spins freely in the bore the case should be replaced.
Bearing Covers
Check covers for wear from thrust of adjacent bearing. Replace covers damaged from thrust of bearing outer race.
Check cover bores for wear. Replace those worn or oversized.
Clutch Release Parts
®
Transmission parts to assure continued performance and
Check clutch release parts. Replace yokes worn at cam surfaces and bearing carrier worn at contact pads.
Check pedal shafts. Replace those worn at bushing surfaces.
Gears
Check gear teeth for frosting and pitting. Frosting of gear teeth faces presents no threat of transmission failure. Often
in continued operation of the unit, frosted gears "heal" and do not progress to the pitting stage. In most cases, gears
with light to moderate pitted teeth have considerable gear life remaining and can be reused, but gears in the advanced
stage of pitting should be replaced.
Check for gears with clutching teeth abnormally worn, tapered, or reduced in length from clashing during shifting. Re-
place gears found in any of these conditions.
Check axial clearance of gears.
2
Introduction
Gear Shift Lever Housing Assembly
Check spring tension on shift lever. Replace tension spring if lever moves too freely.
If housing is disassembled, check gear shift lever bottom end and shift finger assembly for wear. Replace both gears if
excessively worn.
Gray Iron Parts
Check all gray iron parts for cracks and breaks. Replace parts found to be damaged.
Oil Return Threads and Seals
Check oil return threads on the input shaft. If return action of threads has been destroyed, replace the input shaft.
Check oil seal in rear bearing cover. If sealing action of lip has been destroyed, replace seal.
O-Rings
Check all o-rings for cracks or distortion. Replace if worn.
Reverse Idler Gear Assemblies
Check for excessive wear from action of roller bearings.
Shift Bar Housing Assembly
Check for wear on shift yokes and block at pads and lever slot. Replace excessively worn parts.
Check yokes for correct alignment. Replace sprung yokes.
Check lockscrew in yoke and blocks. Tighten and rewire those found loose.
General Information
If housing has been disassembled, check neutral notches of shift bars for wear from interlock balls.
Sliding Clutches
Check all shift yokes and yoke slots in sliding clutches for extreme wear or discoloration from heat.
Check engaging teeth of sliding clutches for partial engagement pattern.
Splines
Check splines on all shafts for abnormal wear. If sliding clutch gears, companion flange, or clutch hub has wear marks
in the spline sides, replace the specific shaft effected.
Synchronizer Assembly
Check synchronizer for burrs, uneven and excessive wear at contact surface, and metal particles.
Check blocker pins for excessive wear or looseness.
Check synchronizer contact surfaces on the synchronizer cups for wear.
Washers
Check surfaces of all washers. Washers scored or reduced in thickness should be replaced.

Introduction
Assembly Precautions
Make sure that case interiors and housings are clean. It is important that dirt and other foreign materials are kept out of the trans­mission during assembly. Dirt is an abrasive and can damage polished surfaces of bearings and washers. Use certain precau­tions, as listed below, during assembly.
Axial Clearances
Maintain original axial clearances of 0.006-0.015 in. for mainshaft gears.
Bearings
Use a flange-end bearing driver for bearing installation. These special drivers apply equal force to both bearing races,
preventing damage to balls/rollers and races while maintaining correct bearing alignment with bore and shaft. Avoid us-
ing a tubular or sleeve-type driver, whenever possible, as force is applied to only one of the bearing races.
Capscrews
To prevent oil leakage and loosening, use Fuller
Gaskets
Use new gaskets throughout the transmission as it is being rebuilt. Make sure all gaskets are installed. An omission of
any gasket can result in oil leakage or misalignment of bearing covers.
®
sealant #71205 on all capscrews.
Initial Lubrication
Coat all limit washers and shaft splines with Lubricant during assembly to prevent scoring and galling of such parts.
O-Rings
Lubricate all o-rings with silicon lubricant.
Universal Joint Companion Flange or Yoke
Pull the companion flange or yoke tightly into place with the output shaft nut, using 450-500 lb-ft (610.12-677.91 N•m)
of torque. Make sure the speedometer drive gear or a replacement spacer of the same width has been installed. Failure
to pull the companion flange or yoke tightly into place can result in damage to the mainshaft rear bearing.
IMPORTANT
See the appropriate Illustrated Parts Lists (specified by model series) to ensure that proper parts are used during assembly of the transmission.

Torque Rating
The torque rating of the transmission specified in the model number is the input torque capacity inLb•ft. Various torque ratings are available. For more information, call your Eaton Fuller regional sales and service office at 1-800-826-HELP (4357).
Shift Bar Housings
Two types of shift bar housings are available for this transmission. Both are described and shown below.
Standard
The standard shift bar housing has a gear shift lever opening that is located toward the rear of the transmission.
Forward
The forward shift bar housing has a gear shift lever opening located three inches closer to the transmission front than the standard opening. This forward design allows greater flexibility in mounting the transmission and is indicated by an "F" in the model number .
Power Take Off (PTO) Usage
PTOs can be mounted in the following way:
6 or 8 Bolt: The 6 or 8 bolt openings are standard with the transmission. The PTO is mounted to the opening and driven
from the PTO gear on the front countershaft.
Thru-Shaft: The thru-shaft PTO mounts on the rear of the transmission. It requires a special auxiliary housing and main
case countershaft with internal splines.
Lubrication Pumps
Internal: An internal lubrication pump is located in the lower front of the transmission and is driven off the upper coun-
tershaft. Transmissions rated
PTO Driven: A PTO driven pump is externally mounted on the 6 or 8 bolt PTO openings and driven off the PTO gear.

Transmission Operating Angles
If the transmission operating angle is more than 12 degrees, improper lubrication will occur. The operating angle is the transmis­sion mounting angle in the chassis plus the percent of upgrade (expressed in degrees). For operating angles over 12 degrees, the transmission must be equipped with an oil pump or cooler kit to insure proper lubrication.
Operating Temperatures with Oil Coolers
The transmission must not be operated consistently at temperatures above 250°F. Operation at temperatures above 250°F [121°C] causes loaded gear tooth temperatures to exceed 350°F [177°C] which will ultimately destroy the heat treatment of the gears. If the elevated temperature is associated with an unusual operating condition that will reoccur, a cooler should be added, or the ca­pacity of the existing cooling system increased. The following conditions in any combination can cause operating temperatures of over 250° F [121°C]:
General Information
Operating consistently at slow speed.
High ambient temperatures.
Restricted air flow around transmission.
Use of engine retarder.
High horsepower operation.
Note: Transmission coolers must be used to reduce the operating temperatures when the above conditions are encountered.

Preventive Maintenance
Preventative Maintenance Check Points
Everyday there are countless vehicles operating over the highways with transmissions in such a neglected mechanical condition, they can be referred to as failures looking for a place to break down. They lack a proper and organized preventive maintenance program.
Preventive maintenance is a general term which applies to all procedures necessary to have maximum life and satisfactory service at the lowest possible cost, short of removing and repairing the unit.
A number of conditions contrary to good preventive maintenance can generally be pointed to when inspecting a failed transmis­sion. Taking a few minutes every so many hours or miles to do a few simple checks could help avoid eventual breakdown or reduce the repair cost. If the transmission is not cared for, it will breakdown.
Service Procedure
Note: Transmission appearance may differ, however the procedure is the same.

Preventive Maintenance
1. Air System and Connections
Check for leaks, worn air lines, loose connections and capscrews.
2. Clutch Housing Mounting
Check all capscrews of clutch housing flange for looseness.
3. Clutch Release Bearing (Not Shown)
Remove hand hole cover and check radial and axial clearance in release bearing.
Check relative position of thrust surface of release bearing with thrust sleeve on push-type clutches.
4. Clutch Pedal Shaft and Bores
Pry upward on shafts to check wear.
If excessive movement is found, remove clutch release mechanism and check bushings on bores and wear on shafts. See OEM literature.
5. Lubricant
Change at specified service intervals.
Use only the types and grades as recommended. See “Recommended Lubrication Chart” (see Table 2).
6. Filler and Drain Plugs
Remove filler plugs and check level of lubricant at specified intervals. Tighten fill and drain plugs securely.
7. Capscrews and Gaskets
For applicable models, check all capscrews, especially those on PTO covers and rear bearing covers for looseness which would cause oil leakage.
Check PTO opening and rear bearing covers for oil leakage due to faulty gasket.
8. Gear Shift Lever
Check for looseness and free play in housing. If lever is loose in housing, proceed with Check No. 9.
9. Gear Shift Lever Housing Assembly
If present, remove air lines at air valve or slave valve. Remove the gear shift lever housing assembly from the trans­mission.
Check the tension spring and washer for set and wear.
Check the gear shift lever spade pin and slot for wear.
Check bottom end of gear shift lever for wear and check slot of yokes and blocks in shift bar housing for wear at contact points with shift lever.
Checks With Drive Line Dropped
10. Universal Joint Companion Flange or Yoke Nut
Check for tightness. Tighten to recommended torque.
11. Output Shaft (Not Shown)
Pry upward against output shaft to check radial clearance in mainshaft rear bearing.

Preventive Maintenance
Checks With Universal Joint Companion Flange or Yoke Removed
Note: If necessary, use solvent and shop rag to clean sealing surface of companion flange or yoke. Do not use crocus cloth, emery
paper, or other abrasive materials that will mar surface finish.
12. Splines on Output Shaft (Not Shown)
Check for wear from movement and chucking action of the universal joint companion flange or yoke.
13. Mainshaft Rear Bearing Cover (Not Shown)
Check oil seal for wear.
Oil Leak Inspection Process
Inspect for Oil Leak
Determine if it is a Weep or a Leak
Weep: Stained, damp, no drips, light oil film, dirt adhered to the contaminated area.
Gasket Rear Seal Leak
1. Clean suspected oil weep area with a clean dry cloth or mild soluble degreaser.
2. Ensure lube is to proper level.
3. Notify the customer that it is only a weep and it is not considered to be detrimental to the life of the transmission.
4. Repair is complete.
1. Do not repair: Rear seal is designed to allow min seepage (refer to Roadranger TCSM-0912 Seal Maintance Guide).
2. Ensure lube is to proper level.
imal
Leak: Extremely wet or dripping of oil in the contaminated area.
Step 1
Step 2
Step 3
1. Determine the origin of the leak path.
2. If origin of leak is obvious skip to Step 3.
3. If the origin of the oil leak is not obvious then use either of the two following steps to determine
the oil leak:
Note: Do not use a high pressure spray washer to clean the ar force contamination into the area of concern and temporarily disrupt the leak path.
i. Clean area with a clean dry cloth or mild soluble degreaser and fill the transmission to the proper lube level. OR ii. Clean the area as noted above and insert tracer dye into the tr transmission to proper lube level.
Operate vehicle to normal transmission operating temperature and inspect the area for oil leak(s) visually or if tracer dye was introduced use an UVL (Ultraviolet Light) to detect the tracer dye’s point of origin. Note: When i make sure the assumed leak area is not being contaminated by a source either forward or above the identified area such as the engine, shift tower, shift bar housing, top mounted oil cooler, etc...
Once the origin of the leak is identified, repair the oil leak using proper repair proced designated model service manual.
ea. Use of a high pressure spray may

Service Procedure
Step 4
After the repair is completed, verify the leak is repaired and operate the vehicle to normal
transmission operating temperature. Inspect repaired area to ensure oil leak has been eliminated. If the leak(s) still occurs, repeat steps or contact the Roadranger Call Cen 1-800-826-4357.

Power Flow
Power Flow Diagrams
An understanding of the engine's power flow through a transmission in each particular gear will assist the technician in trouble­shooting and servicing a transmission.
The Eaton®Fuller®Roadranger transmission can be thought of as two separate "transmissions" combined into one unit. The first "transmission" or front section contains six gear sets which are shifted with the gear shift lever. The second "transmission" called the auxiliary section, contains three gear sets and is shifted with air pressure.
Note: This transmission is referred to as a constant mesh type transmission. When in operation, all gears are turning even though
only some of them are transferring power.

Note: The heavy lines in the figure below outline the power flow description. For help in understanding the transmission compo-
nents, refer to the figure “Transmission Components” on the previous page.
1. Power (torque) from the vehicle's engine is transferred to the transmission's input shaft.
2. The input shaft rotates the main drive gear through internal splines in the hub of the gear.
3. The main drive gear meshes with both countershaft driven gears and the torque is split between both countershafts.
4. Because the countershaft gears are in constant mesh with the mainshaft gears, all the front section gearing rotates. How­ever, only the engaged or selected mainshaft gear will have torque. External clutching teeth on the sliding clutch will engage internal clutching teeth on the selected mainshaft gear. Torque will now be provided from both opposing coun­tershaft gears, into the engaged mainshaft gear, and through the sliding clutch to the front section mainshaft.
5. The rear of the front section mainshaft is splined into the auxiliary splitter clutch and torque is now delivered to the aux­iliary splitter clutch.

Power Flow
Front Section Power Flow - Direct Gear
In direct gear, the front sliding clutch is moved forward and engages into the back of the main drive gear. Torque will flow from the input shaft to the main drive gear, main drive gear to sliding clutch, sliding clutch straight into the front section mainshaft which delivers the torque to the auxiliary splitter clutch. See figure below.
Note: All countershaft and mainshaft gears will rotate, but the gears will not be loaded.
