[QUOTE="skidsteer.ca, post: 8844, member: 307"] You have a spool (stem the coil slides over) that is sticking which is not allowing the aux hydraulics to shut off. There should be no flow until you activate it. Relief is slightly low but that only affects the max pressure. Try removing the spools and cleaning them with solvents and air. You can also switch them from side to side to verify thats the problem. gpm will vary with engine speed. Will it make the same pressure at a idle or does pressure fall off as you reduce rpm? If the spool won't close it could be that it won't fully open either?? Ken [/QUOTE]
