Loader wont hold position

   / Loader wont hold position #22  
Piston seal leaking internally results in pressure intensification under load (explains creep down 6 inches then holding) the load is then not supported by the bore dia but rather the rod dia (less area = higher psi)

shifting valve during this condition results in relief valve blowing over (pressure is higher than RV setting) until intensified pressure is vented to return...thus load drops momentarily...

Forgot to mention if not fixed this can lead to gland and/or seals seeing way to much pressure (possible blow-out):(

I do not like to post this, because I know you will hate me even more ....:D....but I do it for the others, that are more patient with my posts....:thumbsup:

Nah, don't worry. I don't hate you at all. Matter of fact, I enjoy reading your explanations of how things work. Never too old or too smart to learn something. Keep up the great work.
