This is the bronze plunger Quill used to feed oil to the camshaft lobes if using a (pre-Featherbed) central oil feed SOHC cambox, i.e. Racing Internationals, M30/M40 and SOHC Manx.  Normal (aluminium) SOHC CS1/International cambox's are identifiable by having a plain bevel cover - but the competition cambox (normally magnesium shell) was identifiable by having a front bevel cover which had provision for an oil feed - and used this quill to push against the central feed cambox. 

As well as the Quill, we also sell the quill spring, Quill holder, copper washer - and of course the central feed camshaft - all available in this SOHC cambox section

We manufacture this (racing type) cambox Quill in 2 lengths - the most common type is identical in length and profile to the SOHC BigEnd quill (but with a smaller oil feed hole!) - it it this type we will normally supply in this listing.  However, we have also found a slightly shorter variation - which is somewhere between the normal type and the Featherbed type quill in length (approximately 23mm in overall length).  If you are replacing an existing cambox quill and believe it is this length - then you can email me on paul.norman@racingvincent.co.uk when ordering. (Note - We also sell a shorter 3rd SOHC Featherbed Models type - see Item 0067 for this Featherbed Type).

Update Jan 2024:  We are currently out of stock of the longer cambox quill, but are having a new batch manufactured - email me for details if required paul.norman@racingvincent.co.uk

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 the same), 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.
