Having heavy duty tools is essential when you start a diesel repair shop. After all, you can’t do the job without the right truck tools. The best advice is to resist immediately buying everything you think you need. Take it slow, start out with the essentials, and keep building your toolbox over time.
Build Your Own Toolbox
Most diesel tech programs have a list of heavy duty tools students need. Plus, the list grows longer as you advance through the courses. The good news is that you’ll complete your schooling with the beginnings of a useful toolbox.
Heavy Equipment, Truck and Diesel Technician Freshman Equipment List
As a student in a diesel tech course, you have to provide your own tools. Instructors prepare a pretty big list of must-have truck tools you’ll need to collect before classes begin. A sample list of equipment diesel tech freshmen must have includes:
- 1/4-inch square drive socket set, including 6-point sockets, deep and shallow sockets, a reversible ratchet and extensions
- 3/8-inch square drive socket set, including the same accessories listed above as well as a universal joint
- 1/2-inch square drive socket set, including the accessories listed above plus a flex handle
- brakes and suspension tools, i.e., a narrow brake spoon, torque wrenches, spring tools, flare kits, a tire gauge, and a narrow brake spoon
- welding and preventive maintenance tools, such as files, a welding kit, spark lighter, and torch tip cleaner
- fuel and electrical systems tools including spark plug sockets (when you are not working on diesel), round feeler gauges, jumper wire, electrical tape, and resin solder
What’s more, you’ll also need to fill an extensive list of nearly 40 miscellaneous tools including combination and Allen wrenches, a punch and chisel set, vise grips, diagonal pliers, drill bits, measuring tape, blow gun (with a rubber tip), Phillips screwdrivers, and slip lock pliers in addition to a toolbox and shop uniform. Lists can vary between instructors, programs, and schools, so be sure to follow the equipment list that applies to your particular course.
Heavy Equipment, Truck and Diesel Technician Senior Equipment List
After amassing all those tools for your freshman course, don’t be surprised when the instructor hands you a whole new list for your senior course. You’ll need to still have everything from your freshman class, but will also need close to 30 more items including (but not limited to):
- screw extractors
- flexible air hose
- hand wire brush
- bearing race punch
- drive breaker bar
- grease gun
- long picks set
- pump oil can
- dead blow and ball peen hammers
Additionally, on the senior equipment list are ear protection gear like ear muffs or plugs, for instance, as well as a few non-tool items like a calculator, flashlight, and white-out.
The collection of truck tools you need for school can serve as a useful starter kit once you have your certification and are ready to work in a shop. Then, you can build on that, rather than buying a brand-new “complete” tool kit. Even if you buy a kit, chances are you will need to add to it anyway.
10 Tools to Own
There will always be a few common truck tools included in most collections. However, every diesel tech has his own favorite tools. You could compare 20 different toolboxes and find vast differences between them. When putting together a toolbox of heavy duty tools for diesel repair, if you were to ask a few seasoned techs, these are the tools they’d likely advise you to get:
- high-quality sockets—short-wall, deep-wall, 12 and 6-point, impact, metric and standard, Allen and hex.
- ratchets and accessories—ratchets (naturally), extensions, swivels, torque wrenches
- gasket scrapers—all shapes and sizes as well as ones you can insert razor blades into
- hammers—brass dead blow, light (5-pound) steel sledgehammer, and any others you find useful
- pullers and presses—pitman arm puller, all models and sizes, but definitely keep 2 and 3-arm and steering-wheel types on hand
- picks—heavy-duty as well as smaller, dental-type picks
- wire wheels and brushes—cheap, disposable brushes can be used for initial cleanings, but also invest in specialty brushes to finish up
- impact gun (battery-powered)—also consider corded ones for those times when you can’t use a compressor
- scan tool—ones like the Power Probe III is user-friendly and will help you check electrical components and locate short circuits
- specialty tools—disconnects, spindle-nut sockets, tubing wrenches
Purchasing Your Tools
Between equipping yourself for school and adding on recommended tools, it’s easy to become overwhelmed—and drain your bank account in the process. Fortunately, experts have advice on affordable ways to get ahold of the tools you need. For instance, you can search online to buy used sets. Keep an eye out for school sales, too. Programs just like the one you got your certification from sell their used tools on a regular basis when they upgrade their equipment. Lowes, Harbor Freight, and Sears typically offer reasonable prices on heavy duty tools. Additionally, you could consider opening an account with a company that specializes in the type of tools you need such as Snap-On, MACO, or Mac.
Is More Expensive Better?
Even if you can afford the best that money can buy, it isn’t always necessary. Keep the life expectancy in mind when deciding whether to shell out the big bucks for heavy duty tools. It makes sense to spend a little more on truck tools you frequently use because you’ll need them to last for the long haul. On the other hand, buy cheap when you’re shopping for semi truck tools that you rarely need. For example, adjustable wrenches, pry bars, and long screwdrivers are tools you don’t have to spend a fortune on.
Warranties Save Money
Whenever you have the choice of buying heavy duty tools with a warranty, do it. Since you’re building a business along with your toolbox, it makes financial sense to invest in the must-have truck tools that manufacturers guarantee. Those with lifetime warranties are the most valuable because you will only have to spend money on them once. If they ever break, replacing them won’t cost a cent.
Growing as a Diesel Mechanic
Heavy duty tools can be expensive, so the best way to build the ultimate truck tools kit is to do it over time. First, buy specialty tools as you need them, but consider buying used when it comes to big-ticket items. But also make a wish list of semi truck tools you’d like to have but don’t need right away, then keep an eye out for sales. In that way, you can gradually fill your toolbox with all the right heavy duty tools.
Additionally, upgrade as you go. Replace older tools as they wear out. You’ll have more money to invest in better-quality ones as time passes and you’re making more money.
