Hydraulic leak on ls656

[Bill Van Brunt]

I purchased a New Holland LS656 skid steer running kinda (in service mode for 30 seconds). With some advice from the internet and YouTube, I replaced the hydraulic sensor, and it worked! The bucket moved up and down, and it moved back and forth. Yeah!!! Within 5 minutes, it started beeping, so I turned it off. I looked behind me, and oil was everywhere.

I had to pressure-wash the entire engine compartment. I examined the engine compartment and found no signs of a broken or cracked part. I removed the rear skid plate to get a better look, and all I can see is the fuel tank. I added more oil in the hydraulic reservoir, and it soon started dripping oil down the fuel tank.

I'm looking for a way to find the hydraulic leak. Any advice would be appreciated.

Thanks,
Bill

Oh man, I really wish I could help. It would be awesome if someone with experience in LS656 could jump in and share their thoughts. That kind of insight would make a world of difference

Sorry, I'm not sure what I was thinking or typing, for that matter. In my original message, I said I have an LS656 and it is a LX second, of all, it is not a 656, it is a 665.

So the model is a LX665

Hey Bill I’m new to the site and am curious what caused this as I walked into my shop to find a puddle of fluid under my ls 140 after the same repair yesterday.

Might be a loose fitting or seal in the hydraulic system those can be a bit tricky to identify sometimes. Definitely a good idea to check all the connections around the hydraulic lines and fittings to make sure everything is snug and secure

Thanks I can’t believe it would be anything major but all that fluid on the floor got my full attention.

Absolutely, that’ll catch your eye. Nothing like a puddle of fluid to make you stop and take a closer look.

I lowered the rear skid plate yesterday and found the leak it’s a steel line and I’m embarrassed at how much mud was in there. I’m going to have to drop the whole thing in a week or so, machine would have been real handy with this foot of snow I’m staring at!!

Oof that’s a bit of a shocker. At least you caught it before it got out of hand mud can really complicate things, but it’s much better to sort it out now than in the middle of a snowstorm.
