New Eaton Transmissions

Posted: August 1, 2014

Eaton has launched the Fuller Advantage series of 10-speed heavy-duty transmissions in both manual and automated form for linehaul and regional-haul users. The manual version is scheduled for commercial production this September while automated models will wait until the first quarter of 2014. Direct and overdrive ratio sets are offered.

New design features, the company says, include reduced weight and increased efficiency resulting in fuel-economy improvements and an improved shift feel. Other features are said to contribute to lower preventive-maintenance costs.

A new “precision” lube system represents one of the most important upgrades in the new transmissions, Eaton says. It’s said to reduce oil-churn energy losses by nearly 33%. With less heat being generated, the new transmissions do not require a cooler with corresponding lines and fittings. Engine fans cycle less as well, further reducing horsepower demand.

Significant weight savings of up to 75 lb — with no sacrifice to strength – are largely due to aluminum replacing cast iron for the shift bar housing, auxiliary section cover, and range cylinder. Exact weight savings are dependent on the make of truck purchased as vendor-supplied cooler weight reductions vary by manufacturer.

Efficiency improvements and those weight savings can bring, based on initial fleet and third-party test results, a claimed fuel economy improvement up to 1.9% versus comparable transmissions.

Maintenance cost reductions are helped by a new oil-level sight glass that allows for routine oil checks to be performed at a fraction of the time previously required. The lube system uses only 16 pints of oil, nearly half the amount used in similar transmissions.

The Fuller Advantage is good for GCW ratings up to 80,000 lb without an oil cooler, with expansion to 110,000 lb at some point in the near future. Torque capacities range from 950 (1288Nm) to 1850 lb ft (2508Nm). There are standard eight- and six-bolt PTO openings and an optional through-shaft PTO.

Initial production will include 17 new manual specifications with ratios ranging from 15.42 to 17.53. All of the new transmissions come with a standard five-year/750,000-mile warranty for linehaul applications.
