Re: Sq4 bearing removal

That is why a guillotine puller is so called ...it has sharp edges which can be forced into the radius of a bearing race ,separating the bearing from whatever is close up behind it.You could also cut the cage,remove the rollers,and clamp the puller into the thrust shoulder of the bearing...............

Re: Burman GB gearbox

Both Triumph and Norton replacement gear bushes are sintered material,and smaller diameter than the Burman bearings..........if you use solid bushes ,you better keep the oil level up,cause they will seize hard,and lock up the box.

Re: Sq4 bearing removal

It probably simpler to pull the gear and bearing together.......with a 3 leg puller.To pull only the bearing,use a two piece guillotine type bearing extractor and a puller and legs to suit the extractor threads........dont use Chinese rubbish,go for OTC ,or something like .I prefer to use a hydrauli...

Re: What happened to the Ariel Grand Prix racer?

i think times were pretty tough in the decade before the great war.........there were two major financial panics in the US in that time........anyway,I read that the Ariel car was somewhat copied from the Lorraine Dietrich,but Sangster chose to go with shaft drive ,when the French car was chain driv...

Re: Lathe user?

You need 4140HT....this will have the strength needed to get a sufficient torque on the retaining nuts to hold the axle in place,without threads distorting...........it is easy to machine ,and quite cheap,and being hardened and tempered ,needs no further attention.

Re: Primary chaincase disaster

As much as I dislike modern mods on old bikes,I think a belt primary drive on an Ariel might be an exception............still ,a primary chain bustup takes my mind off the millenial drivers playing with phones while I'm out riding.

Re: What happened to the Ariel Grand Prix racer?

I would think 1908 cars would be few......Ariel Motors (1906)Ltd was bust by late 1907,and the factory and contents ,less car parts,were sold to Soc.Lorraine Dietrich. .....a few more Ariel cars were assembled by Coventry Ordnance Works,which would be the 1908 models ,I imagine...........incidentall...

Re: What happened to the Ariel Grand Prix racer?

Some years ago,I did a bit of research on the Ariel Car Company,and it was pretty clear that Charles Sangster raised a considerable amount from investors with shonky claims and valuations ,and spent it all on a handfull of sports cars for him and his mates....Note that this is the 1907 company ,not ...
