Alternator & Generator Strap, Zinc Plated, for VW

EMPI Zinc Plated Alternator and Generator Strap for VW

Vehicle Fitment and Compatibility

This EMPI alternator and generator strap (Part #4523) is designed for Volkswagen Type 1 Beetle, Karmann Ghia, Type 2 Bus, and VW Thing models. It is compatible with 1200cc to 1600cc air-cooled engines. This strap is a required component when performing a 12-volt alternator conversion or replacing a factory generator strap. It corresponds to OEM number 113-903-141B and features a zinc-plated finish for corrosion resistance and long-lasting durability.

Pro Tech Tips for Installation

Verify Pulley Alignment: Before fully tightening the strap bolt, ensure that the alternator or generator is seated perfectly square on the stand. Even a slight tilt can cause the fan belt to be misaligned, leading to premature belt wear or the belt flipping off the pulley at high RPMs.

Avoid Over-Tightening: The strap needs to be tight enough to prevent the alternator from rotating under the torque of the belt, but over-tightening can potentially distort the outer housing of the charging unit. Snug the bolt down until the unit is immobile, then double-check that the strap is centered on the mounting surface.

Check Your Stand Height: If you are converting from a 6V generator to a 12V alternator, you must use a 12V-specific alternator stand. This strap is sized for the diameter of 12V units and works best when paired with the correct height stand to ensure proper cooling tin clearance.
