want stop swinging right

J.R. Britt · Nov 22, 2020

I have an E120B cat and been working great until I was swinging to the right and would not stop. It swings as soon as engine is cranked will not stop everything else works fine even if you pull the lever to stop hydraulis it's still swinging right. Thanks ahead for any help!

Sounds like you have either a manipulator piston hung up or the main control spool isn’t centering because it’s hung up.

Had a chunk of the inner lining of a hose get between the land of a spool and the valve housing. That was fun.

Thanks for your help . it was a stuck plunger in the main valve block. I pulled it out put new o-rings and stuck it back together and works great.
