Yella Terra M90 / L67 Heavy-Duty Supercharger Coupler — YT 1520HD

The Yella Terra YT 1520HD is a heavy-duty replacement coupler for Eaton M90 / Holden L67 supercharger applications. The coupler sits inside the snout and transfers drive from the pulley assembly to the supercharger rotor pack.

High-load replacement

• Direct replacement heavy-duty coupler for M90 / L67 applications.
• Designed for increased supercharger speed, high RPM and higher boost created by smaller pulley ratios.
• Intended as the stronger coupler option for modified L67 combinations.
• Suitable as a service replacement when the supercharger snout is already being inspected or rebuilt.

Application note: This part is for the M90/L67 coupler arrangement. Yella Terra uses a different coupler, YT 1520W, for applicable Whipple superchargers.

Installation: Inspect the snout bearings, shaft, seals and drive components whenever the supercharger drive is opened.
