I hope my reference to the photos of my left side adjuster posted under FILES at the INOA Yahoo forum were helpful.

Yes, thanks. I joined up and was able to pull it up. I rode the bike today. It doesn't have any adjuster as you've pictured. Where would I obtain one of these, and what's involved in installing it.

BTW, the bike ran great. I could barely detect a rattle with the clutch in. . . but then these ears don't hear as much as they used to!
 
Hi Bonwit
I do run sureflex plates in the Triton.
To be fair, I have no complaints, I was just replying to someone who has a rattle and trying to come up with a reason for it.
Not that impressed with a basket that dosn't run true tho' ...thats why I used RGM for the Commando after a less than positive experience at Norvil, (and also they use a better belt type).

Hi Bill.
I know USA is a big country, I was born there. I also used to live in Stuart, Florida for four years back in the 80's.
You didn't actually answer my question, Bill. I asked if you do sustained runs at OVER 4000 rpm, not just sustained runs.
When I lived in Florida everyone drove around dead relaxed, 8) even on the interstate and Turnpike, although I did meet up with some Truimph guys and we used to go out Lake Okeechobee way for some more spirited runs on the backroads out west...I had a 70' Bonneville back then...wish I still had it now to go with the others. The police were dead keen over there :(
We might live on small islands in Europe but they are still big enough to get up to some good speeds. :lol:

the 650 day run's was at 4,000 plus RPM on the interstate's. 13 hour's from Shady Valley Tennessee to Orlando Florida with gas stops every 125 - 130 miles (roadster tank) so I guess that will qualify :D . the small island comment was not meant as a put down but just most britts have no idea just how vast it is here but as you are from here no need to tell you that :oops:.
 
Bonwit, I don't know of anyone who makes and sells left side threaded gearbox adjusters.

My good friend Heinz Kegler made mine for me, it is simple and strong in design, you can see it from both angles on the INOA site.

It is "possible" that he may agree to make one for you, it would not hurt to ask him.
I think his email address is HeinzGP@aol.com
try this but if it comes back as undeliverable let me know and I will ask him for you.
If fact if you want I can call him today and ask him, what is you email address?

BTW, The conversion kit is a Norvil. Is this a good one?

Thanks

I bought an RGM double sided tensioner one in SS and was good quality never seen the Norvil one.
 
I do not believe a left handed adjuster would solve the problem. The gearbox could still be tilted. I reckon the problem is the bottom through bolt, if this was a neat fit in both the gearbow & the engine plates, it wouldn't matter where the adjuster was, as it would remain in line. That's my tuppeny worth anyway.
 
faced with the choice of picking between a right or left side adjuster on a commando,
the only real choice is the have the adjuster on the same side as the primary, hence the left side
I have never understood why Norton put it on the right side.
 
Regarding the left side threaded gearbox adjuster. . . I've not had the cover off my primary yet, so I don't have a good picture in my mind how this is installed. Can you give me a brief explanation of how it works and how it is installed? How do you know you've adjusted it properly? I assume it causes the belt to remain properly centered on the pulley? Is it a big deal to install?

Thanks
 
click here http://autos.groups.yahoo.com/group/INOALIST/

and sign up for a yahoo account if you do not have one already

on the left side is the FILES section, go there, I posted two pictures of my left side adjuster installed,
very easy to install, can one up your self, or someone posted on a belt primary thread a link to a shop
that sell one already made up
 
This is mine using the original but SS LH nut tapped for a 5/16" stud. Just position the fixing hole the same distance from centre of the adjuster opening as on the RH side but to the front. I put mine at the rear originally (same as RH original) and it's virtually impossible to reach with a spanner!!

Bonwit,

I have an RGM adjuster if you want one. Shipping, and it's yours. BTW, mounting it forward is the way to go.

I must agree having had one of those moments when you think 'aah thats simple match left side to right side' 2 hours later all primary side off measure and drill all primary side back on then it dawned on me adjustment was nigh on impossible :oops: :oops:, so all off redrill all on calm is restored..........

Thanks! I sent you a private message.
 
Hi There Just been reading through the posts about belt drives and alignment problems. I'm rebuilding a JPN after a major engine blow up and have got a bit of a problem getting the belt to stay on the pulley's, I have an adjuster on the L/H side but still can't seem to get it to run true. There seems to be a bit of play between the clutch centre and the mainshaft but when you measure this at the edge of the clutch basket it's less than 1mm. The Belt drive was brand new when initially fitted less that 100 miles ago so I don't think the bearing is suspect.Any idea's?
 
When I fitted my Hayward belt drive I also, without thinking, drilled the hole to the rear but I've found with a 3/8 drive and an extension I can adjust it without any problems.
Mac, that sounds really odd. I also have some runout/wobble in my clutch basket but alignment doesn't seem to be a problem. I don't know whether it's play in the clutch centre/shaft or what but I suspect that with the assembly being rivetted together, absolute accuracy is difficult. Mine looks like a shopping trolley wheel when running, but not quite so bad. If the Hardly Dangerous boys can get it right, it shouldn't be a problem for the Norton boys.

Have you got the 1/8th inch thick washer fitted between the upper gearbox mounting on the left side? If you have fitted the gearbox without this it will kink the engine mounting plates and put the crankshaft and gearbox mainshaft out of line, and could be the possible cause of your problems. Don't ask me how I know :oops:

Hi Reggie
I thought this was a washer. I am not sure I have this on the inside of the engine plates on EITHER of my bikes!
So are you saying the bottom and top end bosses are out of line to each other on that side?
Why would they put a spacer there?
I need to check this out on my bikes now, thanks.
Stu.
 
hi bigstu,its only the commando boxes that have the narrower top mount flange,i think they did it to ease gearbox removal from the cradle
