Pete to offer improved Eaton Fuller 11-speed for on/off highway use

DENTON, Texas (June 19, 2000) — Peterbilt Motors Co. will offer a new Eaton Fuller 11-speed transmission on its Models 385, 379, 378, and 357 beginning July 3, 2000. Designed specifically for on-off highway applications, the RTO14909ALL is similar to the model it replaces, but has revised reverse gear ratios.

The new reverse gear ratios in the 9ALL are Lo Lo Reverse 20.85:1, Lo Reverse 13.03:1 and Hi Reverse 3.43:1. “We made the change because customers told us they didnĂ•t need reverse ratios as slow as the forward ratios,” said Eaton Corp.’s Robert Davoust. “With faster reverse ratios, a truck owner can be more productive.”

Due to the significant off-road usage of this transmission, the new 9ALL model includes a severe-duty rear bearing cover with a shield that offers additional protection for the output seal and vehicle/engine speed pickups. The 9ALL transmission is standard with an internal oil cooling pump, a special high capacity auxiliary drive gear bearing and an oil level sight glass. This service feature allows simple visual verification of the transmission oil level.

With a maximum input torque rating of 1650 lb.-ft., this transmission is well-suited for higher horsepower construction customers seeking the low speed capability offered by the 26.08:1 Lo Lo forward ratio, the company said.
