Big End Bearing Shells
« on: April 03, 2017, 02:02:50 PM »
The crank I plan to use on my project bike needs the journals to be reground (20thou probably).

My trusted engineering company is struggling to find shells to suit. Can anybody help with a brand and part number?

Just to tidy up this post, for anyone looking for big end shells in the future.
The Hesketh V1000 and Vampire use Vandervell big end shells, part number VP6502 for a nominal crank pin diameter of 54.000mm.

Unfortunately this does not help Dave S as he is building the Hesketh Vulcan which uniquely has a long stroke crank to take the capacity out to 1200cc and he has now found that the crank pins are a different diameter. Keep searching Dave.
