I have a E-47 and it won't angle left. I know that I have to check the O-rings on the "C" valve. Could someone tell me where it is and how to get it out? I know where the solenoid is. Also can someone help me figure out about the cross-over relief valve. (how to take it out and what to look for if it's bad.) The only thing is the power angle block and any advice on it would be appreciated. Thanks to all!!!!!!!!!
