1970 Triumph Tiger with export wheel hub. Have the wheel removed and
need to disassemble it. With the nut and washer removed I "should" be able
to lift the speedometer gear drive right off of the spacer and drive ring.
But, it won't budge and I don't want to use hammers and crowbar. What can
I be doing wrong?
 
Your doing nothing wrong in my experience. (I've got a 1967, 1969 and a 1970) and it is just plain old ... STUCK !!! ... like mine are sometimes. With the wheel off, and using a three legged puller --- with the axle on to screw against; "gently" pull it off. Put some rags or aluminum plates between the puller jaws and the speedo drive. That's what I've had to do. It is a VERY poor design IMO, and the OIF 1971 on is somewhat better.
 
Sometimes (often) speedo drives can get crushed by over-tightening causing them to close up and ‘pinch’ the spindle.
 
Actually found fresh sealed bearings. Yeah, circa 2000! Very low mileage on this bike since restoration.

Nice !

Looks like you park your Norton on that bench too (it’s left it’s mark)...
 
I have fixed all but one persistent very slow drip from the transmission drain plug. Aaargh!
 
That drain bung should easy enough to seal.

Don’t forget that many leaks from elsewhere will end up down there, making the drain plug look like the culprit!

The gearbox sprocket oil seal has been a regular leaker in my experience.

Got the drain bung to seal. Then replaced the gearbox sprocket oil seal which was leaking pretty good, but it still leaks
though not nearly as much.
