RTLO18918B Eaton – Fuller 18-Speed Transmission
The Fuller Low-Inertia™ Super 18
The ultimate for performance, versatility, and reliability with variable loads and speeds in applications up to 3050 Nm (2,250 lbs. ft.).
More time on the road™ with the Eaton Fuller Roadranger. Unbeatable versatility with 19.7 to 1 overall reduction and 14.40 low gear. Economical performance with 0.73 and 0.86 overdrives for efficient cruise RPM’s. Smoother, faster, easier shifting due to patented low-inertia technology. Exclusive output seal design improves seal life and eliminates potential for seal damage during yoke removal. Faster, smoother range and splitter shifts due to design improvements.
On selected Fuller models an optimized lubrication system provides increased cooling and lubrication for more difficult, harder working applications. Quieter operation and increased durability due to helical gears in auxiliary section. Improved lubrication with standard internal oil pump and oil lines for directed lubrication. Unequalled ratio versatility due to close, even steps in both HI and LO range. Enhanced reverse operation safety due to multiple slow reverse ratios. Flexible performance – can be operated as a 9, 10, 13 or 18 speed transmission.
The RTLO18918B Eaton 18 speed
Also available in RTLO14918B, RTLO16918B, RTLO20918B & RTLO22918B Torque versions.

Low-Inertia Concept:
This innovative, patented design is identified in the Fuller nomenclature by the letter “L” (as in RTLO-18918B). These transmissions feature a simple main shaft which is not splined to the auxiliary drive gear. This unique design eliminates the added mass, drag and inertia of the entire auxiliary section. During upshifts, where both the lever and splitter button are moved together, the low-inertia main shaft is quickly brought to synchronous resulting in fast, easy shifts.
