L3800, LA524 loader, BH77 backhoe, thumb, box blade small wood lot log grapple
While sorting out a fail to lift 100% boom function 100% of the time on a BH77 on a L3800 (that has been an on going issue) I have removed both relief valves and the diverter (behind the bolt between the two fluid lines for the boom valve)for inspection, cleanng and reinstalled them. The push pins on th relief valves worked well.
Next is the spool valve but I do not know how it is removed from the block. I***8217;ve removed the linkage to the control handle and the cover plate held on by two Allen bolts but can not get the spool removed by lifting straight up or un-threading (I***8217;ve counted my rotations should it need to be turned back to original position) the valve.
Do i need to remove the diverted valve (between the fluid supply/return lines) or ........?
I have the WSM but can find no solution there.
Hopeing to NOT remove the entire valve block to inspect/repair/replace the valve.
Any insite would be helpful.
Thank you
