Hydraulic - JMOR, Shaun, etc.

The hydraulic fluid is shooting out the other end of the safety relief valve bad on my Jubilee. I did find the valve finger loose and assumed
this was the issue. I tightened it but didn't fix the leak. Just got a new relief/safety valve today. Question: do I leave the check ball in or
take it out when replacing the valve. The replacement valve is similar yet different. The original is cupped on one end for the check ball with
the new one flat. I've taken the cover off so many times I could do it in my sleep! I'll get it fixed eventually but several of you have had
good advice as you've probably done this one or more times. I did move the pressure relief tube to the back side of the housing as JMOR's
picture showed - thanks for the photo. Alan.

I cant tell if you are speaking of pressure relief or back pressure or mixing them?

The safety valve as it's called in the FO-19 IT shop manual. When replacing this valve do you still use the ball valve or leave it out with the newer style safety valve.

O-19, FIG FO264, item #42 is Safety valve (ram cylinder safety vale to be more specific) and I know of no ball that is user accessible on that valve. FO269, item #94 is Relief valve (pump over pressure relief).. also no user accessible ball. Maybe you are thinking FO263, items #13, 14, 15, 16, 17, 18, 19, 20, 21, 22, all parts of check valve and back pressure valve. #18 is a ball. Post back.

The safety valve is what I'm referring to , IT FO-19 fig. FO73, #69. The spring end is cupped to push against the 7/16 check valve #66. The new
valve is not cupped on the end but flat with a beveled edge. I would think you would still use the check valve ball - but maybe not.

K, check valve. My apologies. I accidentally picked up the FO-20! Yes, I believe the ball is still needed.
