Is this normal for a 3 way?

I have a chrome 3 way on a cocker build I am doing. It looks similar to the stock one. anyways, I am trying to time it and cannot get it to work. It almost seems like the pull on the trigger frame isn't long enough for the orings to clear the outer ports on the 3 way. I first tried my hybrid hinge and then a stock WGP hinge and it does the same thing. I can get it to the point where it moves the back block back and forth but there is leaking at each end of the 3 way valve depending on what position it is in (back block moves back leak out one side; back block forward, previous leaky side seals but the other starts to leak).

Can I fix this or should I try a 3 way that works with a shorter trigger pull? If so, which ones are shorter? I have an evil one that needs an oring. Would this one work?

thanks
-Don

Sounds like you've got some dry/cracked orings. Swap em out with some fresh ones and it'll probably fix the problem. And though it's rare, make sure that the oring guide rod isn't bent, find a level surface and roll it. If it wobbles, that's your problem.

99.9% sure ram oring.
Quick check is to pinch one of your hoses to/from the ram and see if the leak goes away.
if so you need to rebuild your ram. You dont even need to take it off the marker to replace only the piston oring.

Check the barbs on the 3way for any obstructions as well.

I just had a cocker in I was teching and the barbs were clogged with loctite.

ive also ran into some older custom cockers that needed the 3-way unscrewed a few turns to switch properly.

I was working on an older works cocker that had a dye 3way and the actuating rod wasn't long enough. I switched it out with a wgp 3way and it worked fine. Some 3 ways shafts have 2 orings some have 3. The ones with 3 have a longer stroke if I'm not mistaken.

Here's a problem I've seen that limits 3-way travel. The set screw that connects the 3-way shaft to the timing rod needs to engage the indent in the 3-way shaft. If it doesn't it might stick out far enough to prevent the coupler from fitting in the 3-way body in it's forward stroke. It's worth checking.
