Tacho Drive Thread

[Mart UK]

Hi, does anyone have what the thread is for the tacho drive housing (which the cable screws onto)? The threads on mine have rolled slightly preventing getting it further than the first three or four threads, this explains most of my leak there, I think. Would like to see if I can recover it. It looks a bit finer than my UNF tap/die?

Should be 1/2" - 26 (the upper cable end, however, is M12 - 1.0 metric)

Thank you.

An aside ..... To stop rev cable oil




leak I did this . I carefully cut one and a half


coils fom what I will call the outer support spring .This then lets me slide the sleve nut back enough to put 4 tight turns of pink teflon tape on the
spigot / outer cable sleve above the flange
A dab of the bIue stuff and HEY PRESYO and not a sign of oil after 2591 miles , not a dribble in that crankcase grunge pocket .

It maybe somethning to look at when buying a new cable or a fix if you dont mind mods..

Anyway it works and saves money and it works . Fair dinkim .

Existing housings can be modified to take an oil seal, not necessarily the AN one.

Tach seal mod for 850 Commando (2010)

Can you do the tach seal mod for a Commando on a drill press or is a mill needed??? Where do you get the seal. I need to do it on several bikes. Thanks Mark Cigainero
