We are excited to announce yet another DIY project for all A-series engines—a serpentine belt conversion.
As some of you know, we developed a DIY serpentine belt conversion as a necessary preliminary step to drive the Eaton ‘roots’ style blower for the forthcoming, intercooled supercharger project for Spridgets and the Morris Minor.
However, anyone running an A-series engine—including Mini Coopers!—can now convert to a 5-rib serpentine belt with auto spring tensioner. See below picture for how it looks installed on the engine.
You may use a late model Saturn CS121D alternator, the older CS130-style that many already have fitted to their A-series engines, or a late model OEM Lucas alternator fitted with a 5-rib pulley. As in this picture, even a generator will work if fitted with a 5-rib pulley (this is actually a 'stealth' conversion with alternator guts inside a stock generator body).
You may follow this link to see an overview of the project: DIY Serpentine Belt Conversion and links to the CNC-machined pulleys required, both of which are made in U.S.A. at family-owned shops.
Enjoy - and as always, Safety Fast!
