Spanner -maintenace wall chart. for the workshop

You will only forget where the chart is or the reading glasses needed to read it. Getting old sucks.

A chart would be useful IF your bike have all nuts and bolts original. Most bikes I have has been through a number of previous owners. Who has replaced a lot of lost or worn out fasteners. With whatever they found of similar size. Living in a metric country, I've found lots of metric bolts. And quite a number of UN ones. Plus the original mix of BSF, BSW, BSC, UNC, UNF and BA. My solution is to make a service sheet for every bike for the regular maintenance. As an example how it looks:

Primary chain adjustment.

Up/Down movement 21-23 mm.

Loosen upper gearbox nut, 7/16W socket.

Adjust with 3/16W open spanner.

Note. Gearbox MUST be pushed forward, otherwise it will creep rearwards, tightening primary chain.

Tighten adjuster front nut after rear nut.

Tighten gearbox nut.

Usually it’s not necessary to loosen or tighten lower gearbox stud

(19mm spanners)

I also use the excellent Old Britts NORTON COMMANDO TORQUE SETTINGS sheet

Robert, a good suggestion! Tiller, thank you for posting your lists as I've printed off the oldbritts list, very useful. Thanks again.

My mate is well known for his knowledge on a different marque of British motorcycle. Spanner sizes, nuts, bolts, anything original. Its all good until someone gets hold of some spurious hexagon stainless steel bar and makes fasteners from it. The best thing to do if you want a chart is keep it to your own bike. There are a lot of bikes coming back from the USA, i've had a couple and my experience is the Yanks use whats at hand to bodge things. As an example on my Hurricane, the middle exhaust port thread had gone. The repair that was done was drill 3 holes and fit grub screws to hold the exhaust stub in, not good. 

Keep an eye open on this WebSite for the revised version of the Heavy Twins Compilation.  This contains a detailed list of torque settings for the non-Commando Big Twins. The list was compiled mainly by Dale Middlehurst with contributions from other respected and experienced Norton Owners.

Of interest.......as a rule, the post-war twins were generally assembled by hand. It was not until Commandos started to appear, on the scene, that Torque Wrenches began being used when assembling the engines and other big chunks.

Hi Kevin,

Watch this space, Mark (Editor) is working on getting all the Compendiums printed. They will be available in the NOC shop fairly soon. Probably one at a time rather than all at once.
