10 Tech Updates P hillips Industries has released the following tech tips for service providers to best maintain swinger gladhands. Designed to help eliminate damage due to pull-away or tight/jack-knife turns and reduce impact where straight or angled gladhands are exposed to damage, Phillips says preven- tive maintenance should be performed on swinger gladhands at each scheduled preventative maintenance interval or every three to six months. General Gladhand Care Gladhand Seals: Gladhand seals should be checked for wear and cracks that can cause leaks. Replace where any type of damage is present. If gladhand seals have dust fl aps, replace when any fl aps are torn or missing. If using fi lter screens, re- place when damaged, torn or fi lled with debris. Signs of Corrosion: Gladhands that show substantial signs of corrosion on the body, connector and/or detent plate should be replaced. It is suggested to use powder coated or anodized gladhands in highly corrosive environments. Connector Plate: Make sure the small dimple on the connec- tor plate is not worn down. If the dimple is worn down, replace the gladhand. If not replaced, coupled gladhands will leak air because they will begin to lose the ability to seal properly. Detent Plate and Rivets: Look for heavy wear to the detent plate as well as loose or corroded rivets. If the detent plate becomes loose it can eventually break off, making coupling impossible. Replace the gladhand where signs of heavy wear or corrosion are present. Care of Swinger Arm and Mounting Plate/Hardware Swinger Arm/Spring: Joints should be blown clean during pre- ventative maintenance inspections. A shot of penetrating spray can be used to keep the swinger operating properly. Mounting Plate/Bracket and Hardware: Check for loose bolts and tighten where necessary to the proper torque. Check for signs of corrosion on the mounting plate and hardware. Replace if signifi cant signs of deterioration are present that can jeopardize secure attachment of the swinger gladhand to the trailer.

The power steering hose on the affected vehicles may be routed incorrectly, and thus the hose may rub against the power stud on the starter motor, possibly causing electrical arcing and a power steering fl uid leak. Electrical arcing in the pres- ence of leaking power steering fl uid can increase the risk of a fi re. Navistar is recalling certain model year 2011- 2016 IC Bus CE school buses manufactured Nov. 3, 2009, to Feb. 26, 2015, and 2012-2015 IC Bus BE school buses manufactured Aug. 2, 2010, to Sept. 15, 2014. It also is recalling certain model year 2011-2016 IC Bus CE transit buses manufactured July 1, 2010, to Feb. 4, 2015, and one IC Bus BE transit bus manufactured on November 2, 2010. The affected vehicles have a water shutoff valve, inside, forward of driver heater (feature code 48PPJ or 48PPP) that has a formed heater hose that over time, may fatigue and split resulting in hot engine coolant fl uid leaking into the driver's foot area. If hot, pressurized coolant suddenly spills into the operator's foot area, there is an increased risk of a burn injury or a crash. Paccar is recalling certain model year 2017 Kenworth K370, T270, T370, T440, T660, T800 trucks manufactured Feb. 2, 2016, to Oct. 13, 2016, and Peterbilt 330, 337, 348, 367, 389, 567, and 579 trucks manufactured March 7, 2016, to Oct. 5, 2016. The affected vehicles are equipped with certain Goodyear LHS Load Range G tires, size 295/75R22.5 G399A, that due to incomplete adhesion, have a tire tread that may partially separate. A partial tread separation may increase the risk of a crash. Volvo Bus Corporation is recalling certain model year 2008-2017 9700 buses manufactured Jan. 7, 2008, to Aug. 25, 2016. The affected vehicles are equipped with a power feed relay for the engine and transmission which may be undersized for the application, causing the relay to fail and the engine to stall. An unexpected engine shutdown increases the risk of a crash. The following are safety recalls issued by the National Highway Traffi c Safety Administration:
