Yeah had it 10 weeks supposed to be back next week with its new valve block they have changed things to do with the quick hitch but it made no difference and its also had a new hitch ram as it blew its seals the fitter on the job piped the bucket ram to the hammer circuit and he said it cured the problem

It’s what I do!
Ok if it was piped up to the hammer or bi direction auger circuit it could work if! 1 it’s getting flow from a co joined P1 and P2 but also different slice on the valve block, 2 the bucket cylinder internals are damaged in some way, the fact you say you had slew left and right issues points to it being pilot oil supply problems.

Ok when you get it back we can do a few checks via this forum👍

Thanks you obv know what your talking about when i took it in at 60hrs with the slew prob 4 weeks later they said it was due to how they had piped the q hitch up! Its supposed to be due back mon so ill be intouch

They tried a new ram from a sk58 and it was no better so it carnt be the ram and the fitter said p1 and p2 worked seperate not joint so molsons told him to strip the block and also pop out valves but found no faults. The slewing problem occurred at 60hrs so they parked it up but a day later when i came to take it in as they had no transport the slewing was fine but it would only track on one side

P1 & P2 are normally separate, with the exception of when X1 is used (hammer circuit) the flow from both sides of the pump are used in the block for hammer or Auxiliary use. I am guessing that if they are saying they had piped up the hitch incorrectly to start with, then the issues with tracking, slew and bucket are probably all connected by a pilot issue, can you get a full report of all work done?
