Sounds good, I will start on it Monday morning, should be a good time getting to them!

Had a similar issue over a year ago on a RKB 336F. Trash had the NFC relief on top hung open. Cleaned everything up and replaced the relief. It’s still never been 100% since then because I never could find where the debris came from so I will be looking into this. Swing and right track were the main problems as well. With the right operator running multiple functions at once you’d never know it but a lesser hand on it you can see a bit of a delay.

This is what was in it

Yep, that's most likely from the broken check valve.
Here's a pic I had saved.

You’re thinking it’s from the top one that you called out in post #10? Been a while since I stared at all of that stuff on sis for that machine.

It was indeed the top one. Thank you very much for your help!
