Be Proactive to Minimize Corrosion Effects, Experts Advise

Willis by John Sommers II for Transport Topics

NASHVILLE, Tenn. — Corrosion isn’t picky. It will chew into engine block sensors, battery cables, radiators, electrical accessories, lighting systems, brakes, flooring, fuel tanks and liftgate systems, among the other features on a commercial vehicle, experts said.

Their advice: Minimize it, slow it down during a vehicle’s useful life and realize help is at hand for dealing with corrosion, whose “hot zone” on a Class 8 tractor reaches 4 feet up from the road.

If you ignore it, or don’t recognize corrosion as the cause of certain issues, those issues will recur frequently and parts costs will explode, according to discussions during a meeting of the Corrosion Control Action Committee at the Technology & Maintenance Council’s annual meeting here  March 1.

Kevin Willis, fleet manager at Pepsi Cola Bottling Group, said at the meeting that TMC’s manual “Corrosion: Complaint, Cause & Correction” had been a “tremendous help” to his fleet— where prematurely replacing a liftgate can cost $20,000. Reflooring may cost $4,500 on tractors that can be 15 years old.

Willis said his maintenance program now includes spraying a corrosion inhibitor on a yearly basis.

“[We’re] spraying everything in one sweep, including connections,” he said.

The manual is available through TMC’s website.

Several sections of the manual were highlighted during the session. For example, the manual said there are three types of electrical connector lubricants — oil, grease or dispersion. These can be formulated to provide protection. It detailed the characteristics of each lubricant.

“Factors to consider when selecting a lubricant are operating temperature, material compatibility, performance and application method,” according to the manual, which detailed the criteria, too.
