Got involved with a local customers EX60- bad Hyd oil leak from track motor - also filled Final Drive with Hydraulic Oil - gave him a lift to start taking TM Assembly off but one Hyd Feed Adaptor has been welded in - so if I take the ring of bolts out, to take pump housing off - is there anything I need to look out for as I remove outer pump housing to get to remaining 24 mm bolt behind of pump adaptor that will then allow to lift full assembly off?- in a field so making the best of it. Looks like some Floating Seal could be the culprit.
