Kubota Kx36-3. Spares Or Repair

Kubota Kx36-3. I've owned this machine for 3 yrs for small hire jobs , regularly maintained, with air oil and filter changes . The arm was rebushed and pinned 14 months ago . The machine developed a fault when hot the dipper became slow and right side track became under powered ,I was assured it was the pump and had that reconditioned , it still has a yrs guarantee with for the pump . This didn't cure it ,I was then told it was the rotary coupling , I then had that resealed , it worked ok for a couple of days , now the boom won't operate and both tracks don't move .

I've now given up with it . The machine has the red and 2 black keys ,one new track fitted a full set of buckets and JCB sprung quick hitch . I've looked after it and it was a faultless good strong machine until the hydraulic issue . THIS IS BEING SOLD AS SPARES OR REPAIR and will probably need a hiab to collect .
