Norton Navigator 350 gearbox examined and discussed.

[@noeldoran8884]

Well done Paul this type of fault was common in the day and "We" used to just keep riding as we did not have the knowledge or money to correct!!!

[@PeterTaylor-p4s]

Really good explanation, looking forward to the outcome

[@gordonsuddery4635]

Nice explanation Paul, looks like a shining job to me ! The gear box looks good otherwise. My best wishes to you from the Philippines looking forward to seeing the test ride ❤️👍💪😉😀😁🏁🏍️🛺🐑🇵🇭🏴󠁧󠁢󠁷󠁬󠁳󠁿

I think it's worth looking at the selector fork, I seem to recall they were phosphor bronze ,mine wore down badly!

[@whalesong999]

Maybe it will be possible to shim the gear it engages over toward the sliding gear?

[@neilmcintosh1200]

The overall condition is really good. The poor engagement is no great surprise. I wonder if the thing you had to straighten in the selector mechanism was as a result of someone forcibly holding the gear-lever down in an attempt to keep the thing in second. If the fork is out of shape, I would expect it to be a symptom. My money is still on lack of shimming. I doubt the factories took much care over it: The parts lists seldom list shims as available spares.

Have a restful weekend. Thanks.

[@paulhenshaw4514]

Thanks, Herman!

[@PeterTaylor-p4s]

Really looking to the road test

[@davidmarkwort9711]

Looks like a shim problem, seems like that gear cluster is not far enough outwards towards the shifting mechanism

[@elroyosorio8850]

"Nothing too scary in there..."

[@stewartellinson8846]

Is that a pressed steel selector plate? I've seen such a thing on some bikes and they can flex and lead to the forks not moving properly.

[@philipdienelt3521]

What obout grinding the second gear dogs to give an inward taper so with engagement their pulled in together, did the same on my bantam works a treat ,but I guess for a customer you can't realy do this kind of bodge.

[@zdenekzouzazaza2100]

Hi Paul, Is there a chance to save the gear somehow (grind rounded edges, shims) or it has to be replaced anyway? Thank you Zdenek

[@paulhenshaw4514]

Hi Zdenek, I am weighing up the possibility of shimming, it could possibly work.

[@zdenekzouzazaza2100]

@@paulhenshaw4514 thank you... and rounded edges? Is it necessary to take care about them?

[@paulhenshaw4514]

If I can move the gear over enough, it might not be a problem, although a new selector and new gear would be good to find.

[@ianaristotlethompson4186]

Why was the clutch flapping in the breeze.? Pray tell.

[@paulhenshaw4514]

It was loose on the mainshaft, the nut holding it was coming undone!

[@davephilpott6569]

Hi, the selector rod screws into the back of the gear box. That is what the flats are for 👍

[@paulhenshaw4514]

Hi and thanks, but I guess a special tool would be needed for that with the gearbox end plate in position.

[@HAL9000-su1mz]

A shame they couldn't have squeezed a 5th in there. Smaller bikes need it so much more than the larger ones.

[@williamnethercott4364]

Mechanism looks very like my AJS Model 8.

[@paulhenshaw4514]

Yes, they shared components apparently.

[@MONTY-YTNOM]

Wrong gear ?

[@Dwainpipe21]

What a wonderful informative comment, well done ....clap.

[@paulhenshaw4514]

@Dwainpipe21 Yes, it would have been great to be told what the 'right gear' might be!

[@MONTY-YTNOM]

@@paulhenshaw4514 well theres only 2 and one dont fit :)

[@paulhenshaw4514]

I see you added a question mark, so fair enough, but It is the right gear, as is the other one.

[@MONTY-YTNOM]

@@paulhenshaw4514 Haa yer, lazy grammar. Sorry. You know how it is, you get engrossed in the video you think you're in a conversation with the narrative :)
