In regard to backhoe with possible cylinder bypass issues

[FrankBaggs1]

Hello, After watching the video on how to test a cylinder to find out if it's bypassing I was just wondering if I may have leaking cylinders on my FEL as well. I'm assuming that this cylinder drift is occurring while the engine is running???
I have 98' B2100 and haven't used my Fell in a working mode as of yet due to the pending right rear seal change that I need to complete.
Although my Fell functions well when running, if leave the bucket a few inches off the ground when I shut it down the bucket will eventually drop to the ground after an hour or so. Is drift normal when not running or do I have possible have bypass issues with my cylinders and bad seals ?
Thanks in advance !

Frank- it's a good practice to put the bucket on the on the ground when not running.

Leaving the FEL up or an implement on the 3 PH raised puts a lot of pressure on the seals for long periods of time.

I usually put mine FEL in float to lower, then back out, so there isn't pressure on the lift cylinders. There will still be some on the curl cylinder.

If your loader works fine while running, you're good in my book. Just don't leave it in a raised position. It's also a safety issue in the event of a bust hose, or something that can allow the loader to fall.

Good luck

Bleed down is normal in cylinders, especially older ones.
If your getting an hour or so out of a cylinder before it bleeds down, consider yourself lucky.

And as RCW said, store it with the bucket on the ground and the cutting edge flat for safety of all.

RCW, to relive all pressure on all the cylinders, just move the joystick around a couple of times after shutting off.

When I was installing the wall sections on a shop I built, I was happy for cylinder bypass. I would position the wall section over the foundation anchor bolts, get off the tractor and watch as the section slowly came down over the bolts after which I would fasten them down.

My apologies RCW and Wolfman for poor word choice in my explanation. I always leave the bucket flat on the ground as you discribed RCW.
What I should have explained is that I intentionally left the bucket two inches off the ground to see if it would drop and how long it would take to do so. Also, it took more like 45 minutes before it came to rest and not an hour or so.
Sorry fellows, was tired after working a 10 hour afternoon shift and was nodding out when I posted.

Good to know that bleed off is a normal occurrence which I kind of knew it was to some extent. I just was not sure how much was normal and how fast it should happen.

Thanks to the both of you!

That's cheating!
