The saga continues; well at least I felt like I had accomplished something today, I decided that rather than try and strip the rotary coupling in-situ, I would remove the whole lot. Before unfastening any of the hydraulic hoses I decided the best plan of attack would be to first release the bolts which hold the unit to the machine and then the socket caps which hold the unit together, that accomplished I disconnected all the hydraulic hoses to the coupling marking them all so they go back in the right place.
Finally the big moment came for the drop and after hitching the complete unit to a pull-lift and sling, once I took the weight I removed the securing bolts, of course the thing was stuck fast in it's place but after a quick smack with a hammer and bar the seal broke and the unit was resting on the pull-lift and sling which I then lowered to the ground and used the same method to tug the unit from underneath the machine.
I did attempt to strip the unit but it would appear that it needs to be pressed apart and then back together again, so I'm not 100% sure of my next move but hopefully next week I should get the unit sorted one way or another.
