Norton Parts For Sale

These parts have been manufactured over the last 20 years to help rebuild my own bikes. I made a small batch of these parts the remains of which I am now selling. If there is sufficient interest with any of the parts I will consider remaking. - Ian Bennett

Manx / International Norton Rockers
TE11

Rocker 1933 - 1956

Remanufactured from forged EN 24T

£160.00 Each

(including bearings)

 

 

 

TE16

Roller Rocker

 

These are currently under development

In the past i have succsesfully made hundreds of G50 rockers for George Beale so this rocker incorporates the same roller assembly which should eliminate all cam wear and increase performance.

 

 

TE12

Needle roller conversion kit for original rockers.

Consists of needle roller bearings and spacer.

These bearings contain over 3 times as many rollers as the originals, so the load carrying ability is vastly improved. Also as the rollers are smaller diameter they revolve more using a greater proportion of the rocker shaft.

If you are using the original cupped washers the counter bore may have to be deepend slightly as the originals vary a lot - our new washers (below) will work perfect.

TE15

Special Camshaft

This is a special to suit later course pitch bevels, the difference is the number of holes on the vernier, this one has 14 and not 11, as the original.

Norton changed this to give more accurate valve timing.

The big advantage of course bevels is that they are stronger and most improtantly  they are avaliable from several suppliers

Course bevels can be used in international nortons providing the hole for the bottom bevel housing is bored out bigger in the crank case and a sleeve is added to the bevel housing.

Titanium Conrod

Long Stroke conrod 7.5 inch centres

350cc Manx 1946 – 1947

Titanium conrod being machined in house on one of our cnc machines.


To reduce the roller speed these conrods have a smaller bore at the big end ( 2 ") and the outside of the little end has been enlarged.

As the conrod has a 2" bore they use crankpin item number "A7" or "A8" (found in big end bearing section)


Please Note!

Some clubs have banned the use of titanium conrods. Speed way is one such sport to have done this because they are deemed to give an unfair advantage.
