SOHC Ribbed Outer Timing Cover - With Rev Clock Boss (Aluminium)

Product no.: 0321 1X04(R)
This is the 'Ribbed' type SOHC outer timing cover fitted to Norton International and Racing International (early Manx) models up to 1938. This version is the sports\racing version that has a rev clock boss cast in, which were available even in those early days, but as rev clocks were only just starting to be used in the mid 1930's these covers were only made in very small numbers and are now very rare and highly desirable. I am very fortunate to have a friend who has one of these original covers and was able to lend me it so we could have patterns made to produce this exact copy. Please note: these are slightly more expensive than the plain covers, as the casting costs are more expensive with these patterns 05/12: These versions have been faithfully replicated from an original pattrn, even including the original casting number and inner webbing. They have then been CNC machined and for the aluminium versions they are bright polished and ready to fit. 3\16" BSF screws should be used for the rev clock fitting.

SOHC Ribbed Outer Timing Cover - With Rev Clock Boss (Magnesium)

Product no.: 0322 1X04(RM)

This is the rarest of all timing covers - the pre 1938 'Ribbed' type outer timing cover, but made in magnesium. As far as I am aware, there were only a couple of these covers made, for the 1937'ish Big Plunger Works race bike. As I was already having made the ribbed rev clock cover, I could not resist having just a few made in magnesium As with the alloiy versions, these covers are copied from an original and look exactly the same. So, if you want to give your pre-war cammy that most exclusive look - they do not come much rarer than this! Note: in the photos these covers look slightly wet. This is the protective water repellent oil I spray them in before placing them in a plastic sealable bag. 3\16" BSF screws should be used for the rev clock fitting.

 

Update Jan 2016: Sorry, these have all sold out again. Please email sales@racingvincent.co.uk for an update of when they will next be available (but it is not likely we will make them again until the latter part of 2016)

 

Note: we do still have a couple of sets of matched magnesium inner timing cases to Aluminium outer timing cases (the matched pairs cannot be split as they are linished as a pair). Although not using magnesium outer covers, this spec was the standard production Manx pairing

Rev Clock Gearbox 1:1

Product no.: 0338 A11M\546_1
This is a 1:1 rev clock gearbox that can be fitted to any of my outer timing covers. Unfortunately I have not been able to find anyone yet manufacturing the bronze cast type that would have been originally fitted to Norton's in the 1930's-40's, but this is of a very similar design, and was of the type that were commonly fitted to competition bikes from the 1950's. It does however have the correct angle of output and I believe the 1:1 ratio was the ratio originally fitted to pre-war Norton's - but you will need to check your rev-clock Please note - I also stock the 2:1 type gearbox and might be able to get the opposite rotation by special order

It does however have the correct angle of output and I believe the 2:1 ratio was the ratio originally fitted to post-war Norton's - but you will need to check your rev-clock Please note - I also stock the 1:1 type gearbox and might be able to get the opposite rotation by special order

Norton 15 Tooth Magneto Sprocket - Engine Side

Product no.: 0391 A2/79

This item is the 15 tooth engine sprocket that drives the chain to the magneto sprocket, it fits on the end of the oil pump drive gear. These items are just the same in profile as original sprockets - the engine side sprocket being a flat profile sprocket, (while the magneto side sprocket is recessed), just as per originals. These sprockets are well made and (unlike some other patterns) are also heat treated to make them longer lasting. Note: the only deviation from original, is that this sprocket does not have a slot for a woodruff key, while the originals did. This slot was superfluous on the original design, and is actually more hindrance than help - as the woodruff key, if used, can often interfere with the taper fit, making the bond less secure. Note: Fitting magneto sprockets - it is always best when fitting sprockets, to smear some fine grinding paste on the taper fit of the sprocket and gently grind the sprocket to the taper, to get a perfect fit. This is achieved when you have got a matt grey finish on both sprocket and taper. Ensure you fully remove the grinding paste before final fitting. Always use a 'puller' to remove the sprocket, do not try to lever the sprocket off with a screwdriver, as this will almost certainly damage the timing case. A tip when using puller's to remove sprockets - fit puller and screw central bolt until a good tension is reached, then give the end of the puller bolt a sharp sideways tap with a mallet - the jarring will easily loosen the sprocket

Norton 15 Tooth Magneto Sprocket - Magneto Side

Product no.: 0392 A11/112

This item is the 15 tooth magneto sprocket that is driven by the chain from the oil pump gear sprocket, and fits on the end of the magneto shaft (either Lucas Magdyno or BTH KD1). These items are just the same in profile as original sprockets - the magneto sprocket being recessed, just as the original was. These sprockets are well made and (unlike some other patterns) are also heat treated to make them longer lasting. Note: Fitting magneto sprockets - it is always best when fitting sprockets, to smear some fine grinding paste on the taper fit of the sprocket and gently grind the sprocket to the taper, to get a perfect fit.

Magneto Chain + Soft Link (46 Link)

Product no.: 0393 A11/113

Genuine Renolds magneto chain and one soft link, to fit SOHC 500cc and later 350cc engines. Note, these chains should use a riveted (soft link), not a circlip link. I supply each chain with the proper (expensive! soft link) They are extremely fiddly and time consuming to rivet this soft link over, and can sometimes result in a tight spot that has to be 'eased'. Because of this I supply the soft link ready to fit, but do not fit it, as it often marks the chain - then you would think it was second hand!

Magneto Chain Soft (Rivetable) Link

Product no.: 0394 A11/113R
This item is a Renolds 'soft' link to fit a magneto chain. This type of rivetable link is always preferable to a 'split' type link and would have been fitted orignally. These can be fiddly to fit, but the normal process is to fit the soft link, ensuring the back plate of the soft link is resting against a firm metal surface, then use a punch and small hammer to peen the end of the soft link pins so that the outer plate cannot come off. The end of these pins are unhardened for this purpose. It is not unusual to find that once this has been done the result is this link becomes a 'tight' spot on the chain, in which case give it may required slight tweaking and movement to restore full movement. Each chain comes supplied with a soft link, but if you feel you have damaged the link supplied (i.e. hit it too hard with the hammer!), then I also supply these spare links seperately here. These links are high quality 'Renolds' make.

Magneto Chain Link and Half

Product no.: 0432 A11/113H
First and foremost i would say it is not recommended to fit a half link (or link and a half as it actually is), but I know that on some rare occasions you may have an unusual timing covers where the chain can either be too slack/tight with standard links. Therefore this item is for a Reynolds link and a half

SOHC Inner Timing Case Oil Drive Spindle Bush

Product no.: 0459 A11/38

This is the phosphor bronze bush fitted to all SOHC inner timing cases, which is the bearing for the oil drive gear. These bearings are often badly worn on original engines - easily identifiable because excess oil will collect in the outer timing case space (the area containing the magneto chain), and is the outer cover is often not fully oil tight - hence it leads to a common oil leak. This bearing is specially made for me with the correct inner scroll, which stops short on one end, so when fitted the oil will not leak out into the outer timing case space. It also has a slight lip on the same end to aid fitting. Comes complete with fitting instructions.

Update 20/01/16:  Please note, a customer recently reported to us that he tried to fit one of these bearings to an original timing cover and found it slid in under light finger pressure - It should need to press in, i.e. an interference fit.  We had these bearings manufactured from an original pattern, but having checked have confirmed that these bearings have an external diameter of 0.6865". His original bearing was 0.688".  Therefore please can we suggest you check your original bearing before purchasing this one  - if your original bearing measures greater than 0.6865" outer diameter - then this bearing will not be a suitable replacement.  Apologies for any inconvenience this causes
