My bobcat 843 lift arms wont go up unless you activate the auxillary equipment handle and left foot peddle. Ive had the hydraulic control valve rebuilt three times. And the hoses only fit a certain way. Any suggestions?
Did this problem just start up one day? or is this a problem that it had when you got the machine? Also do you have any books for the machine?
It started all at once. We saw the trail of fluid coming out of the hydraulic control valve and took it out. One of the caps had a crack in it, we had it welded and the seals replaced. Put it on and the arms still wouldnt go up. Looked at the HCV and the plunger that worked the lift arms was leaking took it out again had the seals replaced again. Put it back on yesterday and still no lift without working the Aux handle and left foot pad. No book, yet.
