Labour?

You NEVER take (for example) an MB crank to the MB dealer, they will outsource it anyway.

Find your local commercial vehicle independent shop, ask them who the best local crank grinding shop is, go to them direct, should be around 20/25 euros per journal...

TOP TIP.

NEVER tell a tradesman (eg turner) his job, it will cost you extra, go in with the crank, go in with CLEARLY PRINTED (make sure your numbers are correct for the part number) OEM dimensions and tolerances, show him both, ask his advice, follow it.

If you go in and basically tell them what to do, that is what they will do.... sometimes, just sometimes, this is what the turner would actually advise you to do, every other time you just increased your bill...
