Preventative and Periodic Maintenance
Periodic preventative maintenance is imperative for short and long haul vehicles and will extend the useful lives of your heavy trucks. J & W’s periodic fleet maintenance services are comprehensive and include engine, air compressor, alternator, battery, starter, fan drive, transmission, suspension, driveline, exhaust and brake inspections. All systems, including electrical and air conditioning, are assured to be in good working order. Any necessary lubricating, such as of the driveline, is performed, known problems areas are cleaned including the brake and ejector valves, and damaged and decayed parts are replaced, such as the oil filter and desiccant.
Heavy Truck and Trailer Repair
J & W provides emergency breakdown fleet maintenance services as well as regular heavy truck and trailer repair. Comprehensive fleet maintenance services include diagnostic services on engine emissions to determine if you have a bad sensor, bad wire or need a DFS flush (the revolutionary new machine that completely cleans injectors and the fuel system and eliminates the need to remove or replace the DPS filter). Replacing clutches and even rebuilding transmissions and differentials are performed in shop, as well as fixing their leaks. With our in-shop fleet maintenance services, we can replace springs and hangers, and cut, weld and even fabricate frames and trailer skin.
Tire Repair, Replacement and Changeover
Proper tire maintenance is critical to fleet maintenance services, being the third largest operating cost of most fleets.J & W’s tire service includes analyzing the present condition of the fleet, recommending the right product and conducting regular follow-up to ensure satisfaction. J & W offers new tires, replacements and changeovers, as well as emergency fleet maintenance services. J & W Mobile Fleet Services’certified technicians quickly repair the tire, and get your Calgary diesel truck back on the road in no time.
Brake Repair
Freight operators know that many brake problems are hidden. At J & W, our experienced fleet maintenance services technicians realize this as well, and have the experience and skill to determine exactly where your brake defect lies. Hoses and rubber diaphragms get damaged from flying debris in a wide array of places as well as from compressor oil getting into the system. If the desiccant cartridge malfunctions, too much moisture retained in the system can freeze and plug the whole thing up. Knowing this, our expert Calgary diesel mechanics take the time to root out the cause of the problem, eliminate it, and get your trucks back on the road.
Air Conditioning Repair & Recharge
Whether a replacement part, such as an air filter, condenser or blower, a Freon recharge or a new air conditioner, J & W Mobile provides the fleet maintenance services to keep your cabs comfortable. Over time, the system needs to be recharged with new refrigerant pumped into the compressor. Additionally, from time to time leaks develop in either the hoses or a front seal on the compressor. J & W’s fleet maintenance services experts have the equipment to drain and vacuum the system to determine the location of the leakand repair it quickly.
