Eaton introduces aftermarket clutch for I-Shift, new transmission lubricant spec’

LAS VEGAS, Nev. — Eaton has come out with a new aftermarket clutch, designed specifically for Volvo I-Shift automated manual transmissions.

The Eaton 430mm Push Wear-Thru clutch boasts the same engineering and manufacturing features of Eaton’s EverTough clutches, the company announced during Heavy-Duty Aftermarket Week here. The company already offered 430mm clutches in other parts of the world.

The new clutch was designed for longevity. It has organic facings in 232-mm and 254-mm damper sizes. It will be available through all OEM dealerships and master warehouse distributors and through Eaton’s factory direct program that provides discounted pricing when matching with other Eaton aftermarket clutches.

“These clutches will bring the trucking industry a valuable alternative to current I-Shift replacement offerings,” said Monica Metty, aftermarket marketing manager, Eaton. “Similar to all Eaton branded truck components, the clutches will receive the same industry-best Roadranger driveline support throughout the NAFTA market.”

The clutches are maintenance-free, adjustment-free and lubed for life, Eaton says. The new clutch will be available beginning in March.

The company also introduced a new line of synthetic lubricants with new specifications. The new spec’ will come with new labeling and a new name to help customer more easily identify the appropraite lubricant.

A new specification is now available for newer model Eaton heavy-duty manual and automated transmissions and another was developed for its new Procision medium-duty transmission.

“Lubrication plays a vital role in keeping trucks on the road,” said Donna Mosher, engineering technical specialist, Eaton. “So we’ve raised the bar to meet and exceed customer demands for fuel efficiency, extended drain intervals and improved performance.”

The new Eaton PS-386 replaces the PS-164rev7 spec’. It is backwards-compatible and mandatory for Eaton Fuller Advantage Series transmissions, high torque models, all automated units and for extended protection plans. Eaton demonstrated at HDAW the freer flow achieved by the new lubricant, which is especially beneficial in cold weather operations. Initial tests show a 1.5% fuel economy gain when using the new specification, Eaton claims.

The PS-278 specification for the Eaton Procision was specially formulated for the wet dual clutch design and shouldn’t be used with other Eaton transmissions.

The company is also making available light green dip stick tags for Procision transmissions.

“There often is confusion about what the right lubricant is for a particular transmission,” added Mosher. “We’ve made it simple, by either purchasing Eaton-branded lubricants or looking for the new ‘Eaton-Approved Lubricant’ logo on the package. Taking one of these steps will reduce the risk of having the improper lubricant for your transmission.”
