Brake Repair

.

The brake systems of medium-duty and heavy-duty trucks involve highly engineered parts that convert kinetic energy into thermal energy in order to stop the truck. For fleet managers, a well-tuned brake system promotes the safety of truck drivers and other drivers on the road.

Bad brakes display warning signs for impending brake maintenance. These warning signs while braking are cause for seeking a brake service at Triple K Fleet Services Inc.:

  • High-pitched squeaks.
  • Scratching or grinding noises.
  • Shaking or vibrating.
  • Pooling fluid underneath your brakes.

If any of the above signs present themselves in your fleet vehicles, contact us today for service. Our staff is trained in maintaining and servicing front and rear brake systems, plus all accompanying brake system components like brake pads, brake shoes, parking brakes, rotors, drums, and hydraulic systems.

Diesel Repair

.

Truck Repair in Harrisburg, PA

At Triple K Fleet Services Inc., we perform diesel repairs for fleet accounts and commercial businesses in Harrisburg, PA, Camp Hill, PA, Carlisle, PA, and surrounding areas.

Diesel engines play a major role in vehicle performance, so it’s especially important for drivers to be aware of maintenance issues and to seek repairs immediately. There are a number of symptoms you can watch out for that will alert you to an approaching diesel engine service:

  • A diesel engine running at lower RPMs or a hard-to-start engine are signs of low fuel pressure, but these signs may also be symptoms of an insufficient fuel supply or poor fuel quality.
  • If there is oil in the combustion chamber it can create blue smoke as it burns. Blue smoke tends to appear when a driver first starts a diesel engine.
  • Black smoke usually indicates fuel combustion problems. This type of smoke can be caused by a low quality fuel, a dirty air filter, an overabundance of fuel, or other possibilities.
  • White smoke often occurs when fuel is not being burned correctly, and can be caused by worn injectors, damaged valves, and sticking piston rings.

Turbocharger maintenance is also important. Turbochargers increase the compression ignition by quickly compressing the air flowing into the engine, and allowing more air to flow into the chamber. More air in the combustion chamber means more fuel can be added to the combustion process. Turbochargers provide diesel engine systems with improved efficiency, and ultimately, more miles per gallon of diesel fuel.

Because diesel engines make a considerable amount of noise during normal, everyday operation, diagnosing diesel engine problems can be hard to do if you are merely listening in on the engine. Allow our service staff to handle troubleshooting and servicing your diesel engine.

Preventive Maintenance

.

Fleet managers and commercial businesses adhering to a preventive maintenance schedule keep trucks running at optimal conditions. At Triple K Fleet Services Inc., we perform preventive maintenance for customers in Harrisburg, PA, Camp Hill, PA, Carlisle, PA, and surrounding areas.

The goal of our preventive maintenance program is to:

Remember that environmental conditions may affect your ideal preventive maintenance schedule. Depending upon your environment, you may need to seek more frequent inspections and replacements. Truck components and parts naturally wear out over time, and road hazards can negatively impact critical components. It is important to schedule preventive maintenance to prevent problems before they occur.

Steering & Suspension Repair

.

Shaky, unsteady, and stiff steering are all cause for seeking a steering system service. Excessive bouncing or swaying during bumps and intermittent control while driving and braking are cause for a suspension system service. Knowing how to identify steering and suspension issues will help you determine when to schedule an inspection.

Suspension system components—like coil springs, leaf springs, torsion bars, shocks, and struts—help absorb bounce and shock from the surface of the road. All suspension system components eventually weaken over time through stress applied during normal driving conditions.

Our service staff is trained to replace ball joints, shocks, struts, sway bars, and hub assemblies.

For suspension services for your medium-duty, heavy-duty, or semi truck, contact us today.

State & Safety Inspections

.

State inspections help regulate proper truck maintenance, while safety inspections promote safe driving conditions for the driver of a vehicle and every other driver on the road.

For each of our vehicle inspectors, the main priority is to ensure that the medium-duty, heavy-duty, or semi-trailer truck is both well-maintained and equipped for highway use. All of our vehicle inspections are performed in complete compliance with the regulations set forth by governing parties, and we may provide drivers with a full checklist of approved items after the service is complete.

If a vehicle is deemed unsafe by a member of our service staff, the vehicle will be removed from the road. The goal of each inspection is to keep drivers safe by preventing problems before they result in an automotive accident.
