Our homemade Norton Commando clutch hub compressor tool (at right) next to a factory tool. It may not be as sleek, but it works just as well.

If you’re servicing the clutch on your Norton Commando, a clutch hub compressor tool is a must. The Norton Commando clutch is a simple, robust design utilizing a single diaphragm spring to clamp the clutch plates together. Although factory-style clutch hub compressor tools are readily available and reasonably priced, (typically $25-$45), if you’re like us you get a certain kick out of making your own tools when you can, and this is one tool you can easily make, usually for less than $10 if you already have much of the hardware sitting around, as many of us do.

To make the compressor here, you’ll need:

• 1 x stick of fine-thread 1/2-inch all thread or a 5-inch 1/2-inch threaded bolt
• 1 x 1/2-inch bolt washer
• 1 x 1/2-inch fine-thread steel (not nylon insert-type) lock nut
• 2 x 1/2-inch fine-thread nuts
• 1 x 4-inch PCV pressure cap
• Medium (blue) thread-locking compound
