[QUOTE="Onyxfarms, post: 143059, member: 25738"] To help anyone with this issue here is my update. I have achieved 90% operations. I will explain. I will start with the finding of the problem. I removed the Rear Aux Hydraulic Valve and pulled all the components for inspection. Primarily item 4 and 5 of the parts diagram From the pictures, you can see the seals/O-rings are bad. I was able to use the part numbers stamped on the parts to look up the Parker Hannifin part info, and get O-ring data. For those who don't have time to look or worry about cost you can get the O-ring Kits from Bobcat. Bobcat 6653487 Seal kit = $39.00 x 3 = $117.00 Bobcat 6653485 Seal kit = $98.00 x 2 = $294.00 Total = $313.00 I reversed engineered the Parker Number for the individual O-rings. I live in the Houston TX area, and we have several O-ring companies due to the manufacturing base and oil & Gas industries. I sourced all Viton O-rings from a local supplier at an average of $3.00 per valve or $15.00 total. I will add $20 for travel to the supplier on the other side of town, and it is Houston if you know you know...lol So I have $35 in parts with my repair and research time, and as I am now retired, that is free...lol Now to discuss the 90/10 statement. Everything works as required when the solenoid on the Rear Aux Valve Body is "UNPLUGGED". When it is plugged in, I do not get any movement. Why???? I think the spool for that section is stuck and the coil is energized for operation and it shorted somewhere. I did not pull that spool and look at seals, my mistake. I start this search as I move forward, as this may affect the Hydraulics locking on for use for brush hog or backhoe. Issue to be investigated and I will report my findings. I would like to thank the Markle for his help, as it is always nice to run ideals across this Forum. Thanks [/QUOTE]
