Heavy Truck Tools
Heavy duty trucks require different maintenance and repair protocols than smaller vehicles. While many of the components are similar to those seen in smaller trucks, the size of the truck requires a unique set of tools to help in the service, repair and replacement of parts.
Scan Tools
Scanning tools allow truck technicians to find the source of the problem in the function of the trucks components. Scan tools, such as the GSA Contract offered by Diagnostic Innovations, assists in the location of problems in engines, transmissions, and brake systems. These types of scanners are appropriate for both gasoline and diesel-fueled heavy vehicles. In the case of the GSA Contract, which comes in two models, the scan tool functions through a user interface that is capable of being updated and improved depending on the needs of the technician. Other models are additionally available that use the same computer-style set up to analyze the truck without the need to dismantle any major parts.
Drum Handler
With brake drums that weight an average of 120 lbs., drum handlers for work on heavy duty truck brakes are necessary for safe removal and installation. The Drum Caddy offered through Express Brake International is one of many of these types of tools on the market. Drum Caddies allow for the removal, transport and installation of heavy duty truck drum brakes. Placed on the break drum, attached to the axles, tools such as the Drum Caddy provide an easy way to remove the brake drum from the hub of the wheel. In the same way, installation is made easy through the balancing of the drum against the wheel hub. Once aligned, the brake drum can be easily fastened in the correct manner.
Automatic Slack Adjuster
An automatic slack adjuster is used in the adjustment of a heavy duty trucks brake system. Able to recognize the three sections of the breaking stroke, an automatic slack adjuster addresses only the problem area. The automatic slack adjuster is able to measure the clearance for the pre-set running of the system. If the normal setting is incorrect, the slack adjuster rotates to the notch of the control disk and expands to the correct clearance. It can also be used to reduce excessive clearance that occurs when the brake linings or drums become worn.
