Re: What to do?

Do you mean put a roller bearing there? If so, since the oil pressure relief valve is incorporated in the mainshaft taking up some space I wouldn't want to further weaken it in any way. AND the plain bearing holds the oil pressure in. Nev

Re: clutch and mainshaft

I wouldn't put an impact gun anywhere near either of those applications as you don't have anything substantial to oppose the shock forces and may easily chip a keyway or something .All those splines, mainshafts etc are hardened. IF the sprocket is not a tight fit on the spline it's likely to move an...

I've heard it said the one of them has 3 cylinders MORE than you need, but it wasn't ME. SQ 4's are SMOOOTHHH and ideal for those needing a challenging experience. Nev..

Re: What to do?

Suitable Bronze would be fine with the right clearance for it and extra oil flow to cool the bearing but the shaft running in it should be hardened as well Babbit metal runs a much smaller clearance and should not be a very thick layer or it fails earlier. That failed bearing is TOO thick and may be...

Re: clutch and mainshaft

Nothing beats making /having the right stuff to get the job done. Having the bolt in below the inner chaincase is very "clued" too. .Nev

Re: FOR SALE : 1928 model E

It IS in the 30 models but not sure about twin port in the earlier ones . it's a styling and noise exercise. The engines run better with a single port, but when Rudge came out with the four valve in 1925? They all wanted to look 4 valve. 28 OHV AJS were both single port so it wasn't instant but went...

Re: Annoying resonance

Just the fit of the taper in the body under the action of the spring .You can dismantle it in situ but in either case the tank must be empty. Try tapping it into and out of the taper and exercising it. If the taper ends up too far in you might have to redrill the hole for the fuel to get full flow r...

Re: Annoying resonance
