6. Power Tools

You wonder if you need power tools while running your mobile medium-duty repair business? To loosen and tighten large nuts and bolts, you will require high torque to drive the fasteners. 

Without power tools, you will use a lot of energy and spend a lot of time handling a single task, lowering your output.

Since you are your boss, guarding against the time you spend on repairs and maintenance, you need powerful tools to make your work easy, faster, and more accurate.

These portable power tools are your go-to equipment to add to your must-have list. They include;

Multimeter. If you are an electrical truck technician, you need a multimeter to identify a short circuit or any other electrical problem in your client’s vehicle. A multimeter will check the circuits, battery voltage, sensors, current, frequency, resistance, and temperature to determine an issue you should fix.

Test lights. In addition to a multimeter, Test light tools may help you detect the presence of a voltage in a switch, fuse, or relay to diagnose an electrical issue and help you fix it.

Vacuum and pressure gauges. This diagnostic equipment will help you examine the pressure and vacuum in the engine to identify leaks and damages. 

Engine-related issues are sometimes complicated. Diagnosing the exact cause will save you time and help you repair the problem accurately, saving your client from incurring extra costs on repair and downtime expenses.

8. Battery Chargers

While diagnosing and repairing semi-trucks, having a jumper starter cable is essential. 

If a vehicle has trouble starting or a dead battery, you need jumper cables to jump-start the battery while diagnosing other issues or making necessary repairs.

9. Specialty Tools

Some vehicle parts require specialized equipment to repair and maintain. 

Parts like the engine, suspension, brakes, steering, and suspension system require more specific tools to fix and handle them for accurate repairs and a successful mobile mechanic business.

Here is a list of some specific tools you will need while handling some parts in a vehicle.

Engine tools. For an accurate diagnosis, repair, and maintenance, you will require a cylinder leak-down tester to identify engine leaks, a timing light to test and adjust the ignition timing and ensure it works effectively, and a compression tester to diagnose and identify valve leaks and worn piston rings.

Suspension and steering equipment. If you are a suspension and steering system repair buddy, you need spring compressors, tie rod tools, and ball joint separators to help with repairs and replacement.

Transmission tools. For transmission repairs and maintenance, you need a fluid exchange tool to flush and replace the brake, transmission, and coolant fluids. Flushing and replacing used oils will keep your client’s vehicle healthy and improve its lifespan. 

Brake tools. As a mobile truck technician specializing in brake repair and maintenance, having brake caliber tools will help you repair and replace brake calibers.

You also need a brake line tool to repair and replace brake lining and a brake bleeder to remove air bubbles from the brake lining to ensure they work effectively.
