Tractor-Satoh Mitsubishi Beaver
Hydraulic pump replaced 4 years ago
Original valves Cessna 30922-300
New valves Nortrac 45463
2spool valves
Old valves replaced due to leaking badly. Still raised the bucket fine and rotated the bucket fine. Just would not hold bucket in place.
Always slowly dropping.
Ordered new 2 spool valves from Northern Hydraulics and installed.
Bucket will raise up and bucket rotates fine just a little slower.
When i put a full load of dirt or gravel on bucket it does not raise
unless I give tractor full throttle.
Not sure how many gpm old valve was, new one is rated for 12gpm
but manual states 8gpm and 1000psi setting at factory that is
adjustable.
Put pressure gauge on input line and at idle gauge shows about 100
psi and when bucket raises it goes up to 500 psi. When bucket curls
it goes to 800psi.
So why will the bucket not raise up as it did originally? Is it just a
pressure adjust on the valve, valve bad, wrong valve.
Cannot find a lot of info online for old valve.
