Tried to badger X, but he was ignoring me on the dog 'n' bone today.
What is the recommended solution to the difference in crownwheel bolt sizings (shank Ø) between my 4P locking centre and the original Centura 2P open? It's about 1/16".
Also, what bearings do I use that fit in the Centura caps, but over the 4P housing ends? The ID is appreciably larger. What are they likely to cost (just curious)?
Anyone got favourite bearing brands, or ones to avoid?
Is regular gear oil OK for assembling the centre?
Thanks, Adam.
