Double clutching is a commonly accepted practice for shifting through gears on a semi-truck’s transmission. It’s called “double clutching” because it takes two movements to achieve. The first time you tap the clutch the transmission goes into neutral, the second time you tap the clutch you slide it into gear. It’s a one-two beat: neutral, gear, neutral gear, that requires timing. Often employed when climbing uphill or gaining too much speed while descending from a higher elevation, double clutching prevents gears from grinding to extend the life of the gear box and reduce the need for trailer repair. That, of course, translates into money saved!
For new truck drivers, double-clutching can be a bit tricky, not only because it’s a newly-acquired skill but also because every truck is different and has different clutch springs. Once a driver “gets the feel” for the rhythm and timing on his or her particular truck, it does get easier. In fact, most seasoned truck drivers will tell you they don’t even have to think when “double clutching.” It just becomes a natural part of driving a truck.
Whether you are new to truck driving or looking to refresh your skills, a certified truck-driving school can help you with the “ins and outs” of double clutching. Most states require potential big rig operators to demonstrate double clutching expertise during CDL skills tests, and most trucking companies also expect their prospective drivers to demonstrate that they know how to double clutch.
Mastering the art of double clutching will pay dividends by limiting wear and tear on your truck’s gearbox and extending its life. While that means a reduced need for trailer repair, we do remind you that gearboxes should undergo periodic maintenance including an oil change to keep them in the best working condition. As the old saying goes, “An ounce of prevention is worth a pound of cure.”
The American Gear Manufacturer’s Association www.agma.org recommends oil be changed after the first 500 hours or 4 weeks of operation, then every 2500 hours of operation or every 6 months, whichever comes first. It’s also important to periodically check for gear erosion and have a vibration analysis performed to detect any issues that might go unnoticed during noisy trips on our nation’s highways.
