T-20 Woes.....

[Stonewall]

Check to see if your t20 case uses the epoxied in liners for the o rings rather then just holes bored in the case. Sometimes the liners loosen up and fluid leaks between liners and case making it hard to tell just where the leak is coming from. If so they will have to be re epoxied. Also next time you have the case apart use the 2 oring plungers and polish and radius the inside edges of the holes just in case you push the plungers and orings inside case after its together that way you can pull them out without causing any damage.

Mine just has the holes bored straight into the case. I know it's somewhere around the plunger, because when I move the lever back and forth, it's like I'm pumping the fluid out of the case.

I had a similar issue with the T-20 that is currently in my Bigfoot (used in 3 machines and 3 full tear downs in 6 months to find the problem). Finally found that one of the plungers was drilled/ tapped too far and had a hole all the way through. It would be fine for a while, but eventually fluid would start to seep out around the adjuster threads.

I never even would've thought of that, I'll check that out.

If you want to know quickly use florescent dye and a black lite. I use this at work to find hydraulic leaks. works great and takes all the guess work out of it. It's not real expensive.

Spectroline.com - Industrial - Fluorescent Dyes is a very good one and can be purchased in many different colors for specific application. The yellow/green works very well for detection. Can be purchased in small bottles.

Hope this offers some help.

Thanks, I will try that.
