Re: the ariel spares co

I recall George Yeomans collection......think it was mid eighties.....I suppose he s passed away by now,he would always bend your ear about how the smarties got all the good stuff before he woke up to what was valuable and what wasnt.

Re: Burman rebuild

Norton pre AMC boxes have no space whatever for a seal,and owners do use sealed bearings.....however ,the seals arent very substantial ,and dont last long........However ,Burman CP boxes use an odd bearing,which generally needs to be remanufactured aftermarket......Anyhoo ,Burman boxes do have some ...

Re: To Aussie members Help needed

It s worth sending a letter adressed to just the name,suburb and postcode.....however Darlington is one of the rapid development areas where larger properties have been sold to developers ,so many new residents over recent years........If you are really keen ,a search of the electoral rolls for the ...

Re: Tapered roller bearing steering head

Tapered rollers used in a partial rotation mounting should have some preload,and never have any endfloat ,or they will brinnel quickly.

Re: Daily Fixing and Riding Diary on an Ariel 2020

You can usually specify if you want something like a zinc chromate primer ,or an etch and undercoat .....if you say nothing ,its quite possible to spray a high build paint over bare steel......OK while the paint is a perfect seal ,but bad news if you get a scratch or chip that exposes metal.

Re: New member, '52 VH500

I got some balls from the local bearing shop for a Burman recirculating ball nut steering.......when I was fitting them,the ball nut jammed up ,so I measured the balls .....they were miles out ....I took them back ,and the counter guy said the spec is for plus or minus 002.....which is ridiculous......

Re: Mystery SQ4 engine number

i think youve got this the wrong way around ....the cases were stamped by the authorities here in Australia........Ariel would not have even been aware of it,so there is not the likelyhood that any factory records would exist .....Commonest example IMHO was Perkins engines.......most owners used to ...
