Procure Vital Tools and Services

Even if you’re excellent at DIY repairs, it’s difficult to survive during breakdowns without hazard triangles, flashers, warning devices, and towing services.

Purchase Quality Spare Parts

When it comes to spares, you can choose brand new parts (from manufacturers), replacement parts (third-party manufacturers), or used parts.

Ensure to always consider quality, warranty, and your semi-truck repair financing options before you buy any spares.

Semi-Truck Maintenance Tips

You can prevent many simple as well as not-so-simple problems by having regular servicing and preventative maintenance done on your rig.

Yes, regular maintenance will keep your brakes from grabbing, the engine from humming, and the undercarriage free from dust.

Here are some preventative things you can do to avert major repairs:

Create a Plan to Check Brake Wear and Failure

Brake failure arguably the biggest cause of accidents involving semi-trucks.

Thus, it’s crucial to have a professional service your vehicle’s brakes regularly to avoid catastrophic results that often lead to damages and third-party lawsuits.

How long a rig can roam between brake servicing depends on the driver’s driving habits. And no matter how good of a driver you’re, always have your brakes inspected and the fluid changed every once in a while.

Also, have the brake pad, bushings, pins, and springs changed regularly as they wear quickly. For the drums, your experts should replace them at the same time with shoes since they develop heat cracks and also wear down.

And don’t forget to ask your service provider to grease the S cams, slack adjusters, and check the horses as well as linings.

Conduct Tests to Curb Engine Problems

Drivetrain and engine problems are notorious for taking trucks off the road.

Thus, it's advisable to always keep an eye out for signs such as loss of oil pressure, decrease in power, and excessive smoking. These symptoms indicate that you’re riding on an unhealthy engine.

Other than that, your maintenance provider should undertake period compression tests as well as monitor exhaust and engine coolant temperature.

This way, you’ll nip all major engine issues in the bud.

Prevent Body Problems

Many load carriers endure extended downtimes because of body corrosion.

Corrosion emanates from rusting, which is mostly caused by the chemicals and salt used to treat ice and snow.

If you’ll be driving through snowy areas, you can’t prevent rust, but you can slow down the corrosion process by:

  • Having big paint chips removed
  • Washing your truck every ten days
  • Spraying door locks to protect them from moisture
  • Cleaning the rig immediately after rain, snow, or sleet
  • Avoiding parking or driving in large puddles

Good vehicle storage will also prevent rusting.

Maintain Lubrication

Keep your truck lubed in the steering, drivetrain zerks, and suspension with only high-quality grease.

In fact, it’s best to lube all applicable fittings and parts as well as check for slop and leaks in the drivetrain area before each haul.

Be Wary of Extended Idling and Short Trips

City driving and short trips are engine killers.

So if you can, try to avoid them or simply prepare well in advance. You can have a pre-lube system installed so that your vehicle delivers oil to critical parts using an electric pump to avoid cranking. You can also go for a tuber timer for alerts when the engine heats up too much.

Inflate Your Tires Correctly

While over-inflated tires are prone to premature tread wear and blowouts, under-inflated tires can negatively affect your rig’s fuel efficiency.

It’s, therefore, paramount to inflate your tires to the proper levels.

Check for Storage and Fuel Tank Contamination

If you want to keep your engine purring and the fuel flowing seamlessly, strive to keep the tank free from moisture or contamination.

Ask your maintenance provider about the most favorable moisture control treatment.

Protect Your Trucks With Proper Semi Truck Repair and Care

Next to equipment and fuel, semi truck repair and maintenance are the costliest aspects of any trucking business.
