Re: Re: Daily Fixing and Riding Diary on a mainly Ariel 2018

An alloy head does make pinging less likely and the oil temp drops measurably. They are a more maintenance thing though .Stripped threads and loose guides more common. They are also more mechanically noisy. Every little noise comes through the fins. Nev

Re: bearing removal

The babbit metal is supposed to be tinned onto the steel Whether it was or not the end result is caused by fatigue. The thicker the babbit layer the worse it is at taking load. White metal (another name for it) is very forgiving of a bit of muck and should have very small running clearances so it do...

Re: ARIEL 500 RED HUNTER 1934

Not so common these days. Appears to have a folding K/S Pedal. A fairly rare item. All these things are a bit of a lottery. I had a RH 350 of the same year and got my original licence on it in 1956. Cost me 3 Pounds and 10 shillings. (The bike not the licence) Nev

Re: Dynamo Commutator Question

The "old" way of undercutting them would still be the way I'd go. They've probably taken a short cut and not bothered to do the hand work. Get a fine 32 tooth hacksaw blade and grind the "set" off the side of a portion (end) the get the thickness correct and prevent making a mess...

Re: BA gearbox inner case woes

Welding in the centre of anything is more difficult as there's more stress put in the metal. Also there's a lot of remachining to do there. Not an economical repair really while there's others available with none or easier repairs. Nev

Re: bearing removal

Heat it evenly away from drafts and press or carefully drift the bearing out. If you can cool it (the bearing) with a wet rag all the better. Always support the area around the bearing. Nev

Re: W/NG Front Brake Cam

That Drum diameter is close to standard size which is 6.5 inches in Imperial measures. I hope you get the sort of pleasure from your W/NG as I have from mine Luis. I first put it on the road about 1998 . 20 years with not even the head off it again. Rear chain and rear tyre. That's all. Nev

Re: VH cylinder base gasket

Generally I don't recommend using a thick gasket under the cylinder of most bikes but the base of a VH barrel is ridiculously thick so will never pull the corners off it or distort. Use a thicker gasket if you wish, although it will only hit if you rev the guts out of it when things do stretch a bit...
