Extensive Transmission Model Coverage
The manual lists a large selection of Fuller heavy-duty transmission models, including RTLO-12713A, RTLO-18918B, RTLOF-16913A-T2, RTLO-12913A, RTLO-20918B, RTLOC-16909A-T2, RTLOF-20918B-T2, RTLOF-22918B and many additional configurations.
The model nomenclature section also explains transmission identification information, serial numbers, torque ratings, shift bar housing configurations, lubrication pump options and PTO arrangements. This makes the manual useful when identifying the correct transmission configuration before beginning service work.
In-Vehicle Service Procedures
The in-vehicle service section contains procedures for components and systems that can be serviced while the transmission remains installed in the vehicle. Procedures include removal and installation of oil filter adapters, Roadranger valves, slave valves, air lines and hoses, air filter/regulators, gear shift controls, neutral and reverse switches, shift bar housings, oil seals, output yokes and flanges.
The manual also provides procedures for removing and installing auxiliary sections, splitter cylinders and range cylinder assemblies. These procedures can help technicians perform targeted repairs without unnecessarily dismantling the complete transmission.
Transmission Overhaul and Bench Service
A major part of the manual is dedicated to complete transmission overhaul procedures. The manual provides detailed disassembly and assembly procedures for the gear shift lever, shift bar housing, input shaft, auxiliary section, splitter components, countershafts, mainshaft, synchronizer assembly, reverse idler gears, clutch housing and auxiliary drive gear.
It also covers mainshaft assembly procedures involving selective and non-selective tolerance washers, low-force gearing, countershaft installation, bearing installation, integral lubrication pumps and auxiliary sections with tapered bearings.
Inspection and Reuse Guidelines
The manual provides inspection precautions for determining whether transmission components should be reused or replaced. Inspection information covers bearings, bearing covers, clutch release components, gears, shift lever housing components, gray iron parts, seals, O-rings, reverse idler gears, shift bar housings, sliding clutches, splines, synchronizers and washers.
These inspection procedures are particularly useful during overhaul work because they help technicians identify excessive wear, damage, pitting, discoloration, cracks, abnormal clearances and other conditions that can affect transmission performance.
Lubrication and Maintenance Information
The lubrication section includes transmission lubrication requirements, filter maintenance, operating-angle information and oil-cooler requirements. The manual warns that improper lubricant selection can affect warranty coverage and specifies that engine oils and gear oils should not be mixed in the same transmission.
It also explains operating temperature considerations and conditions that can increase transmission temperatures, including slow-speed operation, high ambient temperatures, restricted airflow, engine retarders and high-horsepower operation.
Recommended Tools and Service Equipment
The manual includes a recommended tool section covering equipment useful for transmission service. Examples include torque wrenches, large sockets, brass drifts, dead-blow hammers, snap-ring pliers, feeler gauges, crow’s-foot pry bars, air-pressure gauges and universal bushing drivers.
The tool information helps technicians prepare the correct workshop equipment before beginning transmission disassembly and reassembly.
Technical Diagrams and Service Information
The transmission overview diagram in the manual identifies major assemblies including the front section, mainshaft, countershafts, input shaft and drive gear, clutch housing, reverse idler, auxiliary housing, auxiliary countershaft, range cylinder, reduction cylinder, Roadranger valve, air filter/regulator, slave valve and shift bar housing.
The manual also includes model identification diagrams and illustrations showing different shift bar housing configurations, providing useful visual reference during identification and service operations.
