The first of many - "how does that fit" questions. I find if I stare at the parts book long enough, and play with the parts I can figure it out... but I am having trouble believing the conclusion I am drawing.

I know of the lip seal conversion and I am saving that for a snowy day. (for future reference, anyone know the seal part #)

The rev counter gear I received has a groove 2/3rds up the shaft - I was assuming an o-ring sits into this groove. The o-ring I have fits the shaft - not the groove. I notice that the manual illustrations don't have this groove.
Is the o-ring supposed to sit at the base of the gear- sandwiched between the housing and the gear?? Shocked


Thanks,
Phil

Fastback,

The lip seal is Honda part number: 912 07 222 000.

Good luck with your conversion.

Thanks for the info guys!

I got the following answer straight from The Horses Mouth (which mouth you ask? Andover that is...)

Quote:
You obviously have the later tacho drive gear which requires a very small O ring in the annular groove near the top. 06.1282 is the early one which locates over the spindle and in an appropriate recess in the base of the housing. I'll send the correct O ring (06.5203)...


Dave,
Thanks for the tip. I suppose it would be overkill to install the o-ring and the lipseal on the newer gear. Would it fit? If it keeps the oil in...

I certainly agree that the line drawings of the official manual/parts book and the grainy photos of the Clymer, Haynes & Bacon etc... leave much to be desired, what do you suggest I use as a technical reference? (the forum at jerrydoe.com?!) Wink

Thanks again,
Phil

Fastback,

I have both the o-ring and lip seal installed on my '75 Commando tach drive.

The Unapproachable Norton Commando

At the end of 1967 the Norton Commando was announced.

The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.

It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.

Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.

It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.

The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
