When i lift the machine by putting down pressure on the loader it will stay there till i hit up,then it just lets the machine on the ground but wont even try to raise the bucket.
The lines are preformed steel and will not switch over to the other spool.
The only other thing I was going to try was swithing the tilt lines over to the extra spool that is not in use than switch the lift lines over to where the tilt lines were.
Even this may be impossible with the prefab steel lines,theres just not much give in them.
I really think the valve is leaking internally or possible a relief valve is opening because when I try to raise the bucket I can hear oil inside the valve going somewhere
I havent ruled out cylinders yet but just dont understand why they have down pressure with no problem
i could switch to another valve but it would change everything from original and I would really like to keep it oem
If anyone knows of a good valve i would be interested
Mine is a TD6 Drott Skid Shovel but not the 6-1 loader,just a bucket.
The valve has 3 spools but just uses 2 of them
This machine belonged to my uncle who purchased it to clear the land and build a pond when he and my aunt first bought their ground.
It did alot of work for him and just about the time he was finishing up one of the clutches went out.
He tore the dozer down and went thru the steering clutches and decided the engine was tired enough so he had it rebuild.
He used the dozer very little after than other than for some finish work around the new house.
He passed away a couple years ago and I told my aunt I would like to buy the dozer to which about a month later I bought it.
It runs like new and operates great till this started.
Needs blasted and repainted plus a better set of tracks to be pretty nice.
I have the manual for it if anyone would ever need part numbers.
Thanks for all the help so far
Other than building a few logsplitters over the years I have very little hydraulic experience
