Fleet Maintenance

Avoid Breakdowns and Costly Repairs

Regular and consistent preventive maintenance of commercial vehicles reduces your diesel truck and equipment downtime and reduces repair costs. Mobile Wrench provides a broad range of diesel truck, trailer and equipment fleet preventive maintenance, including oil/fluid changes, filter changes, unit greasing, full safety inspection and other diesel truck mobile services that will keep your fleet operating at peak levels. We’ll inform you of deficiencies and provide recommendations on repairs or other services needed.

 

Services We Offer

Mobile Wrench offers a wide range of fleet maintenance and repair services for your trucks and equipment.

Preventive Maintenance A (PM-A) Service

PM-A, commonly referred to as a “Dry PM,” involves the inspection, greasing and other maintenance required for diesel vehicles, trailers, lift gates and other equipment. These periodic and often internally mandated services don’t typically include major fluid or filter changes. Mobile Wrench’s onsite, mobile fleet PM-A inspections are customized to comply with your internal inspection requirements.

Preventive Maintenance B (PM-B) Service

PM-B services, commonly referred to as “Wet PM.” PM-Bs involve changing oil, oil filters, fuel filters and air filters; checking all fluids; greasing the unit; checking and inflating tires; and a thorough safety inspection of the entire unit. We will inform you of any failures and deficiencies we find, along with recommendations for repairs or services needed.

Trailer Preventive Maintenance

Periodic trailer preventive maintenance is essential to reduce downtime and unexpected repairs for all types of trailers (small, single-axle trailers and goosenecks to full-size commercial 504-foot over-the-road trailers). Trailer preventive maintenance services include greasing the units; inspecting the bearings, seals and brakes; and checking the battery systems and lights. We recommend these preventive maintenance services be performed at least annually (best done when doing annual DOT inspections). We will inform you of any failures and deficiencies we find, along with recommendations for repairs or services needed.

Liftgate Preventive Maintenance

Liftgate breakdown can take delivery trucks out of service with little warning. Mobile Wrench’s mobile mechanics provide scheduled liftgate maintenance services – including full greasing, checking all electrical components and inspecting liftgate support structures – to help ensure these trucks stay on the road and making deliveries.

Benefits of Mobile Fleet Maintenance

Diesel repair shops can be a nuisance to deal with. If you’re sick of their hassles, consider the benefits of working with Mobile Wrench instead:

  • Trucks remain on your site
  • No wasted labor driving trucks to, and from the shop
  • Reduced downtime
  • No tow required
  • Works around your schedule
  • Qualified mechanics
  • Inspections to ensure compliance
  • Control costs with preventive maintenance
  • Lower overhead

With mobile fleet maintenance, the trucks are always on your site. This is convenient, efficient and increases the control of your fleet and removes the uncertainty of when you will get your truck back.

You’ll be able to avoid downtime because on-site maintenance will help you avoid breakdowns. In addition, if your truck still operates you can continue to use it rather than it sitting at the shop waiting for the repairs to be completed. No more having a truck sitting at the shop waiting while the shop prioritizes everyone over your truck. You will have your truck maintained and repaired on your schedule.

Speaking of your schedule, mobile fleet maintenance can work on your vehicles when it makes sense for you. Just set up the appointment and they will be out at your convenience. Some providers will even service your trucks on weekends.

The fleet mechanics that come to your location are all highly qualified. Your vehicle won’t be handed off to an apprentice trying to learn the trade but is left to their own when things get busy.

If you have to take your vehicles to a shop for maintenance or inspections, you’re more likely to skip it. When the maintenance and inspections can take place at your site and at your convenience, you will keep up with them. This helps you ensure compliance and keep your costs down with preventive maintenance.

The only other way to get repairs done at your site is to start your own maintenance division. Mobile fleet maintenance lets you get the same service with less overhead than it would cost to start up a maintenance division: no hiring additional personnel, no buying tools, and no adding extra space.

Why Fleet Maintenance Is Important

When you are operating a fleet, maintenance is the most important thing you can do to maintain operational effectiveness and control costs. Below are six ways that maintaining your fleet helps to make your business more profitable.

Keep Vehicles on the Road Longer

Well-maintained vehicles don’t wear out as quickly. Rotating tires, changing engine oil, lubricating under chassis components, regularly regen DPF systems, rotating tires and more can all extend the lifespan of your vehicles. The longer you can keep a vehicle on the road, the more you can postpone buying a replacement, all of which equates to significant savings on your expenses to make your business more profitable.

Avoid Surprise Downtime

Having vehicles out of service (OOS) because of mechanical failures causes problems and loses money for your business. In addition to surprise expenses, you will also have a downed vehicle that is not producing revenues. This can mean people sitting around collecting a salary but unable to work, renting a replacement vehicle, schedule interruptions affecting customers or trying to rush diagnostics and repairs of the damaged vehicle. Even if you are able to complete the necessary task with just a delay, this can jeopardize a contract and your company’s reputation, which can be far more expensive than the repairs to the vehicle.

Maintain Fuel Efficiency

Poor vehicle maintenance can reduce your vehicles’ fuel efficiency. If your vehicles aren’t getting regular maintenance, their fuel efficiency can decrease by more than 10% for just a few simple items. Neglecting maintenance over the long term can lead to even more dramatic losses in fuel economy, and that can really make your fleet a lot more expensive to operate.

Avoid Vehicle Accidents

Many aspects of routine vehicle maintenance affect vehicle safety: brakes, tires, steering, even lights can all significantly impact your fleet’s accident risk. You count on your skilled drivers to avoid accidents, but they can’t do that if the vehicle’s systems aren’t in prime operating condition.

Poor vehicle maintenance that causes an accident can put you at high risk for extremely expensive lawsuits, too.

Pass Inspections

One in five roadside inspections results in an OOS violation. These violations are as bad as a malfunctioning vehicle: your truck can’t get back on the road until you resolve the violation. Fortunately, most of the OOS violations are easily corrected with routine maintenance: inoperable lamps, brakes not adjusted, flat or leaking tires, and more.

Frequently Asked Questions About Fleet Maintenance

How does fleet maintenance reduce my operating costs?

Fleet maintenance can reduce your operating costs in several ways, including:

  • Maintaining fuel efficiency
  • Avoiding breakdowns and repairs
  • Avoiding accidents
  • Remaining incompliance
  • Improving resale value

Fuel is one of your biggest operating costs, and regular maintenance impacts that. Just a few minor maintenance steps can improve your fuel efficiency by 10% or more. Meanwhile, maintenance can also head off many breakdowns. Maintenance is less expensive than repairs, plus it helps you avoid expenses related to unexpected downtime, like idle drivers, having to rent a replacement truck, or paying penalties because you can’t meet contractual obligations.

Accidents are very expensive, and keeping your fleet well maintained helps you avoid them. Even when you have an accident, having a well-maintained fleet reduces your liability in a potential lawsuit.

Failing inspections can have the same consequences as a breakdown, plus it comes with a fine. Many OOS violations come from simple maintenance failures.

Reselling your vehicles can help your fleet’s cash flow, and you will get more for a well-maintained vehicle.

About one in five roadside inspections results in an OOS violation. According to the Federal Motor Carrier Safety Administration (FMCSA), the most common ones are:

  • Tire flat and/or audible air leak
  • Brakes that are not fully operating properly
  • Inoperative turn signal
  • No/improper breakaway or emergency braking
  • Flat tire or fabric exposed
  • Inoperative brake lamps
  • Inoperable required lamp
  • Brake tubing and hose inadequacy
  • Axle positioning parts defective or missing
  • Leaking, spilling, blowing, or falling cargo

Most of these are preventable with regular fleet maintenance.

We offer full maintenance services, including:

  • Dry preventive maintenance (PM-A)
  • Wet preventive maintenance (PM-B)
  • Trailer preventive maintenance
  • Liftgate preventive maintenance
  • Hydraulic equipment preventive maintenance

We can tailor maintenance operations to your fleet. Just give us a call and let us know what you need.

Typically, you should perform vehicle maintenance according to the manufacturer’s guidelines. This means having oil changes according to the recommendations, which might be as frequently as every 3,000 miles for light-duty vehicles or as much as 20,000 miles for heavy-duty vehicles. In addition, you should perform dry preventive maintenance at half this interval: from 1,500 to 10,000 miles.
