Old Britts – Upgrading the 1971 Side Stand Lug
Download the complete PDF version using the green download button at the top right of this page for a detailed Old Britts technical article covering the upgrade of the 1971 Norton Commando side stand lug. Written by Fred Eaton, this guide explains why the original 1971 frame-mounted stand lug is often replaced, how the later-style bracket improves long-term serviceability and how the upgrade is normally carried out during a complete frame restoration.
The article notes two main reasons for the conversion: the original 1971 side stand pin can break off, and the matching 1971 side stand is no longer readily available. It also explains why clamp-on replacement stands are not an ideal substitute, as improper use can crimp the frame tube. Photographs compare the original side stand lug with a frame that has already been converted to the later bracket arrangement.
Further sections cover removal of the old bracket by careful cutting and grinding, positioning the new factory-style bracket and using Andover Norton drawing references to establish the correct fitment angle. The article includes a full-size 18-degree positioning pattern, shows the bracket clamped in place before welding and highlights an important welding caution: the top center of the bracket should not be welded, so the side stand nut and washer can sit flush against the bracket.
