fork bushes

[garybam4711]

Hi I now have front fork bushes in stock in 45 & 50 shore available at British bikes 1970

[John Wakefield]

Well done Gary in sourcing & stocking these and keeping Greeves on the road and track https://www.britishbikes1970.com/par...otZaejcmoCvayk

Great, but unfortunately supplied with no 'dogs'.

Great, but unfortunately supplied with no 'dogs'.

Gary is getting a batch machined with slot so will be available shortly,

[IanCordes]

Alternatively, if you are in urgent need, you can have the slots milled yourself; 0.610" wide (-0.000"/+ 0.005"), 1/8" deep.

[John Pattinson]

Or I have filed the slots myself, not that difficult.

[tonyed27]

One side of the bush in the suspension link in my 24RES has the slots in the inner 'race' which engage in the cast alloy retainer the other side has 'half holes' in the outer 'race' which engage in round pegs in the other cast alloy retainer.
I could form the half holes in the bush by turning a sleeve to fit over the OD of the bush and drilling down the interface to achieve the half hole in the bush.
I assume there were several iterations of the metalastic bush that had
a) no slots
b) slots both sides
c) slots one side, half holes one side.

[John Wakefield]

The outer holes are drilled after the bush is fitted, they just provide a key for the bush to stop it slipping. So you drill new holes after fitting a new bush. This is only normally needed on off road bikes, the interference fit should in itself be sufficient in road and road racing bikes.

Thanks John

British Bikes 1970 now have both the slotted and non slotted bushes in stock https://www.britishbikes1970.com/parts/fork-parts

Hi! Gary is supplying me with new bushes as mine failed on the trailer-ride to the event last weekend!. It's not surprising, judging by the mess inside when I removed the aluminium end caps and a good job I wasn't riding when it happened. My brother is going to machine a new set of end caps, (cups?), but Gary did mention he saw someone had used a jig to drill through the end cap and frame/bush at the same time. Does anyone perhaps have a drawing or a photo of a jig they used? Thanks in advance...

[IanCordes]

The club archives, available to members, has a drawing.

[garybam4711]

The only information I have seen wile going though is the information already on this forum
Gary

[Brian Thompson]

Same here Gary, the drawing for the jig being GST 1 which I posted along with loads of other related info on this thread in the Members Only area. The jig drawing is the fourth pic in post #4. There are lots of great contributions from knowledgeable members on that thread.

Hope this helps,

Brian.
