Did any of had this happen to your big-end? Does any of you have a replacement con-rod and big-end for a 1930's 500 cc OHV Sloper?

What sound did it make when this happened....

Hi Hans..An bloody expensive sound
...If the guy can't find an original big end I might be able to help with a newly manufactured one (subject to examining the crank and original pin to determine the exact spec.)
I can't help with a conrod but Peter at Cornucopia would be worth a try...also Mark at British Spares Austria. Both a bit pricey though, especially Mark. Gilbert Bredimus in Luxembourg might be worth a try as well...or Leon (unless it's his crank!!).
Alternatively, can another rod be modified? That depends on the overall dimensions, but for example, an M20 rod machined down narrower at the big end..Ian

I wasn't there when it happened but it came to a grinding halt 
It's from the BSA Sloper from a friend of me, I'll let him know that you can have a big end made.

Hi Henk, If the B31 conrod is the same length as the Sloper one then you may be 'in business'. This would work fine as a substitute. You will need to check the width of the rod at the big end and machine the sides to the Sloper rods dimension if required.
The B31 rod is stronger around the big end anyway.
I didn't see a cage in the original pics...is the Sloper big end a 'crowded roller' type?
If so the pin will probably be a different diameter to the B31 type. Worth a look though. I'd be interested to see a picture of the pin when the crank is stripped....Ian

Hi Dave,
I have asked my friend take some measurements, here a drawing.

This one was the one I thought it may have been, but mine is smaller in length, but surprisingly it has a larger bearing surface

Hi Henk, I have e mailed the guy who makes my bigends regarding this one. I'll let you know what he says when I get a reply. It might be useful if you draw a blank with replacement parts.By the way...what is the length and diameter of the rollers?....Ian

No Sloper parts I am afraid but I did find a very nice BSA pump and some other small items.
