The 631's copped a boat trip from France (vinci?) the 637 copped a ride down the M1 it did have a Coal bowl that was returned back to a standard muck bowl, I am going back to the site next week to gas up the necks and sort a diff lock issue, the Nitrogen charge in the neck is via 2 cylinders, 1 cylinder is low pressure around 450 psi the other cylinder is higher at 1200 psi to give a smooth ride with the bowl full or empty, the cylinder charge spec is firstly sorted by the part N'o on the cylinder then the day temp' to a set scale to adjust the charge as needed, then the charge pressure is checked after about a month to monitor pressure loss, if all is good at this point the re-gas is done at around the 3 month spot.
