This is the bronze plunger used to feed oil to the camshaft lobes - if using a Featherbed central oil feed SOHC cambox.
Note the Featherbed cambox used a shorter quill than pre-Featherbed models to avoid fouling the top frame tube. It also used a shallower external nut which we also offer (Item 0069)
We CNC manufacture these quills to the original Norton pattern from the best quality Colisbro Nickel Silicon bronze (it has a more coppery look than regular phospher bronze, and Norton originally used a similar hard wearing material).
Note : These plungers are NOT interchangeable with the Bigend Feed Quill/Plunger (even though they look similar), as this plunger has a smaller feedhole! and fitting one into the BigEnd will damage the engine. If you have a cambox using this quill type fitted, always take great care to ensure you keep this and the BigEnd quill seperated. If you have a box of old quills and are not sure if you may have fitted a quill of the wrong type, email us on sales@racingvincent.co.uk email for information on hole size correct for Bigends.
The accompanyning photos shows the complete Featherbed cambox quill assembly on the right, with similar pre-Featherbed cambox assembly on the left.
This listing is for the quill only, other parts are sold seperately, price is each.
