So, I stopped by my dealer to buy an oil filter the other day, and I brought up my issue with the cylinder. The dealer told me to check the pins and bushings. So, last night, for the first time ever, I removed my FEL bucket and quick attach (QA). It was pretty easy to disassemble. I removed the pins from the bucket/QA and also one pin from the dump cylinder on the left side. I saw what appeared to be "normal" wear on the pins...slight grooving. But nothing major. The bushings themselves seemed okay too. I took my time and removed all of the "dirt-infused" grease from each pin/bushing, and then I replaced the pins and the QA (left the bucket off for now). I re-greased everything. I noticed after I re-greased the FEL, that the cylinders were "tight" again...not loose or sloppy at all.
So, this makes we wonder if the grease has a lot to do with this looseness. I assume that the joints (pins, bushings, etc.) have a little slack in them to accommodate the grease.
The funny thing is that I greased the FEL about a month ago and hadn't used the FEL much at all since then. I'm pretty religious when it comes to greasing my equipment. So, it should have had plenty of fresh grease in it. However, when I removed the pins, I didn't see a lot of fresh-looking grease (I use "Green Grease"). I was near the end of the tube, so I'm wondering if maybe I didn't squirt a bunch of air into my zerks...I don't know.
So, for now, it looks like I've fixed my problem. My next problem is to figure out the easiest way to re-attach the bucket to the QA. Anyone out there got a good trick for that?
