A Chevrolet Service Truck equipped with a ZENA mobile welding system

The pictures on this page detail key aspects of a ZENA welder installation into a 3/4 ton Chevrolet service truck with a V-8 engine.

Service truck with underhood welder

In this case, the truck had a serpentine drive belt system, necessitating the use of a ZENA Add-A-Pulley™ retrofittable secondary pulley assembly. This accessory eliminates the need to make any changes to the stock drive belt system.

Add-A-Pulley on existing alternator


Add-A-Pulley™ attached to existing alternator.

Mechanical installation of the Welding Power Generator was accomplished by making a simple welded support bracket which attached to the vehicle's existing alternator bracketing, and which was combined with a ZENA A300 universal mounting bracket (drilled and tapped for two 5/16” bolts) which was attached to the support bracket with two 5/16” bolts.

This vehicle is used for frequent welding jobs and was also equipped with an ASC1 automatic engine speed control accessory and a BJ150.4 lead extension kit which is used to make it easy for workers to attach and remove welding and control cables.

Time to install from scratch - approximately 4 hours (including time to design installation, bore and tap holes, buy materials and fan belt, and bracket fabrication).
