Hello All, would anyone be able to tell me how much play i should have in the rear wheel cush rubbers. I think mines a bit excesssive as every time i go down one of the many potholes i get quite a clunking sound as the wheel and drive activate. Its no problem on a smooth rd. I would say i have got 5 to 8 mm play.
If i need new rubbers where can i purchase them from?
thanks in advance for any help
tony
Gidday Tony,
I don't have info for your particular bike, but in case no one else can provide specifics, here is a quote from a workshop manual for my Enfield, which has rear cush drive rubbers:
"Before removing the wheel, even before putting the machine on the center stand, apply the rear brake, and rock the machine fore and aft, observing how much movement is possible against the cush drive unit in the hub. If the wheel rim can move much more than about 1 1/2" - 40mm along its circumference, you may want to order a set of cush drive rubbers, so that you can change them the next time you have the wheel apart."
By the way, how did you get on with sorting out the primary side lubrication\breather system on your bike ?
Cheers,
Bevan
Hi Bevan, thanks for the reply. I have a lot of play, not sure if its 40mm, less than that i would guess. I hate the nasty clunking noise when i go down a pothole and the wheel catches up.
so i need to find a supplier of cush drive rubbers.
With regard to the oil , breather issue i blanked it off and regulary spray the chain with a lubrucant.
been using the bike every sunday , 160 mile plus runs with no issues, except a sore bum at the end of the day.
its been trouble free and attracts a lot of attension when i park up.
Need another project now, i keep looking but the price of these old machines has rocketet
Cheers

Hi Tony,
If you have no luck with finding suitable BSA cush drive rubbers, you could always investigate whether you could buy the quite large Enfield ones and chop them to suit - they are readily available.
Just finished a project myself - total rebuild of a 650cc Panther. My 29' BSA Sloper engine is next on the workbench; goes well enough, but I have no idea of the engine history, so will strip it down to hopefully avoid any nasty metal shredding disasters. Clutch & gearbox also need a bit of fettling.
Must have an addiction; just bought an Ariel VB as well - can't justify why, just wanted one :)
You think bikes are expensive in the U.K. - just try buying one and shipping it over to where I am in N.Z. - two to one exchange rate and 15% GST at the border - I must be mad !
Cheers,
Bevan
Good idea about cutting some down, need to get the wheel out and measure them.
Love the old bikes❤
Hi Guys, you know i said i had play in the rear wheel cush rubbers.....i got it wrong.
Just taken out the rear wheel and found i dont actually have rubber cush drive rubbers fitted. The quick detachable wheel actually has metal lobes that mesh in the holes also metal in the rear drum.
My question now is can i get the two parts? Or are they part of the rear drive hub and rear wheel?
Any one got an exploded view of the rear wheel? That would help me determine whats what.
Any help or advice would be greatful
cheers
tony
Hi Tony,
My "Book of the BSA" has the diagram below. The text says that the wheel hub engages with 3 driving pegs on the wheel hub and empathises the need to ensure the three retaining bolts shown in the diagram are very tight on reassembly. I wonder if those bolts had been a bit loose at some stage and the slop has worn the driving pegs, or similar ?
Hopefully, someone with a similar bike to yours may be able to offer something more helpful.
Cheers,
Bevan
Thanks Bevan, mine is different to that, my pegs are actually rectangular and are fixed to the wheel hub, they fit in rectangular lots in the rear brake drum.
no doubt various designs over the years
I have got 1.2 to 1.5 mm play which sounds small but i feel that movement when i go down potholes, worst is the clanking sound when the wheel then gets its driveback.
cheers
tony
