Hopefully this is the end of Slew Pot issues.
Today I added hose protectors to the new slew pot hoses - mainly as the near side one had originally been grouped with the tiny 'boom lock' hose to give it some support, but the sleeve had hardened and cracked off as I fitted the new hose. The same sleeving had been used where the hoses are clamped between the king post and it's cradle so it seemed sensible to carry on to the off side hose. I already had the spiral wrap so it was a no cost choice !
Then I filled the slew gear box - darn silly place for the filler - the only way of getting at it is to stretch to the boom and dipper out on the ground then reach in behind the boom pivot where the (plastic) filler bung sits covered in all the hydraulic hoses ! And to complicate matters the filler incorporates a breather so a deep socket is needed when you can guess what size it is (1-1/8" AF for future reference)
Squeezy oil bottle is about the only way of getting the oil (4 litres of 75W90 GL4/5 Universal gear oil) in as the spout is needed for its reach.
Having done all that I brought the machine out into the yard where I could try full left and right slew and check no hoses were stretched.
Glad to say all seems to work

The only thing to work out now is how to torque those bolts to 990 Newton Metres - my big torque wrench runs out of steam at 550 NM ! (But they are blooming tight! )
