Loader Ck2610 Weak Lifting Power

[Merc1100sc]

All, I have a CK2610 HST TLB. Been good so far for the most part but now, at 150 hours it seems as though the loader has lost a lot of its lifting ability. Last complete service was done at 75 hours. Any ideas before I contact the dealer. Thanks

Do you have a single joystick on it? If so check the bolt on the underside of it. This loosened up on mine and I lost my travel which means it felt like it had no lift capability.

 

[Merc1100sc]

Yes. Single joystick. I will give that a try. Thanks

If the three point control is set to all the way up it can reduce pressure to the loader. Back it off a bit and the loader may function normally.

 

[Merc1100sc]

I normally keep it at a lower setting but I will double check this also later.

Can you clarify what you mean by lost its lifting ability? Is it raising slower? Not able to lift something it used to be able to lift?

 

[Merc1100sc]

Not able to lift things it easily used to. I have not had a chance to look at it again yet but am hoping it痴 as simple as the nut being loose as mentioned above.

Small update. Found the loader lockout lever was completely disengaged. Seemed like it might have been limited the travel of loader control lever/stick. Didn't get a chance to try it last night but hoping that does something.
Regarding the possibility of the bolt under the lever coming lose, I don't see one. The lever goes directly into the valve body for the loader control.

You have a different setup than my Kioti which has a separate lever with cables going to the actual control valve.

Update. The loader lockout mentioned above didn稚 really make a difference. Spoke to dealer. He suggested to make sure the loader doesn稚 settle quickly when left up for a min to rule out leak in system.
Also mentioned hydraulic fluid could have foamed at one point causing a weak lifting scenario. Seems like this is unlikely as I would think the HST would feel weak also, which it doesn稚. Same fluid right. Anyhow, if so said sometimes a filter/fluid change may fix it. I知 at 75 on this change anyway so will do it. I have Mobil 424 in it now. Thinking about trying the TSC brand, which I will ask about in a sep post. Said after that can adjust relief valve. And very least possible pump replacement, which he痴 had to replace one so far of the units he痴 sold. Hoping to tinker with it today.

Does anyone know the hydraulic flow in this model before I start adjusting pressures? It is pump, 3pt, then loader? I believe adjusting a valve upstream can alter what happens downstream and possibly cause damage?

Did you try reset the quick disconnects on the hoses? Sometimes they can pop off if not seated right or something hit it.

 

[Merc1100sc]

I have not. Wouldn稚 there be a leak if not seated correctly? I will try anyway as it can稚 hurt.

Sometimes it will leak, sometimes it won't. There are several threads here with similar issues that ended up being the bad seated quick disconnect.

Update. Disconnected and reconnected all hoses. No change. Dug a small pond yesterday with BH and no lack of power there for its size. I知 wondering if I知 just expecting too much out of the loader. If I drive into a pile of mostly wet dirt, should it be able to curl and lift without me having to back out of it slightly??

Its normal to need to back up a little to break loose and lift/curl a compacted or wet pile of dirt.

If you are in doubt, get a pressure gauge to check the pressure. Then you can adjust if it's out of spec.

 

[justman777]

If it's not lifting the same load it used to, then something is probably wrong. Like ptsg said, your best bet is a pressure gauge and a spec sheet.

i wouldnt replace mobile 424 with the tractor supply brand... not saying the TSC stuff is bad but the 424 is DEFINITELY better.

 

[Merc1100sc]

I think I am going to use it a little more and see. If it still feels weak I will check the pressure. Also I will most likely stick with the 424.

FWIW I had the same feeling recently. Was using my CK2510 at my BIL's project. The FEL didn't seem to have the same power. And with a heavy load it was settling. I had to hold it in lift to keep it up (no jokes please). Also the BH joysticks were getting loose. So we went directly from his project to the dealer. They pulled the cylinders on the FEL and one needs rebuilding. One of the BH valves need rebuilding too (that disappoints me as there isn't a lot of hours on the BH; maybe 200).

They also checked the pressure output and it's at spec. The BH felt weak too but I think it's because we were digging thru old compacted rocky and buried asphalt or oiled QP.
