Good day!
Attached you will find a photograph of a big end a customer recently supplied for building the crank for his post-war twin. He tells me that it came out of an Alpha Bearings box, but I have never seen a similar big end before. This is not a great photograph, so a few details: The slots in the cages take 1/4 diameter by 5/16ths long rollers which are fitted into the reduced diameter on the pin and then held by the cages. There is a spacer for the rods which fits over the largest diameter on the pin. It is all very well made, but I've never seen one of this design.
Just wondering if any of the other members here have seen this design and recall anything about their performance.
Thanks for any and all comments!
