[QUOTE="skidsteer.ca, post: 4552, member: 307"] Sounds like some dirt went through your hyd valve body (control bank) Are the aux hyd on they machine controled by electric over hyd, or does it have a linkage that goes to your valve body? Did your aux hyd ever work in float mode?, if yes, then something in the new valve is letting the hyd flow return to the resevoir instead of the pressure going through the aux hyd. The valve has 3 sections, one for lift, one for tilt and one for aux hyd flow. Oil flows from 1 to 2 to 3. This way the maufacturer give priority to the function thsy feel is most important, then 2nd priority and low priority. Probably lift then tilt then aux 1 always get the oil first then the 2nd spool and finally the 3rd. While spool 1 is in full use (your lifting at max speed) then spool 2 and 3 are not getting any hyd oil so they can't function Does your tilt still work in float mode? or is it “MIA“ as well? The detent could be a broken or missing spring about the size of a ink pen spring but stiffer. Both issues your dealer should be able to fix easily. Ken [/QUOTE]
