How tight should loader pin nuts be on a CK2610 (KL4030C loader)? Is there a torque spec?

Thanks, maybe I mispoke and they are not the pin nuts? They are the large nuts that keep all the loader joints together. I figure if they are too loose, would that not encourage side to side play when using the loader?

These nuts...

Thanks I would consider them snug now, they were quite loose in some cases. Not sure how the ear got bent, but it was not from me snugging the nuts. I put maybe 15lbft on them, if that.

What would contribute to having grease flow out of the face when I am greasing the pins? It is very obvious on some locations, and in others it is not an issue. You can see a little in this picture.

Yep, I understood which ones you were talking about Those are not to be tightened. If you do, only do so until they barely touch the metal and no more. (Though preferably, back them off a hair).

On my 4030 (no C) the pins are only held in by teardrop keeper and a C-clip:

Notice how loose it really is, so no worries about it not being tight.

As for the grease squeezing out, its normal. When you grease a pin, the old grease (and dirt) gets pushed out and is what you want. Just wipe up the old with a rag.

While you are there, look down and locate the loader bracket bolted to the frame. Tighten the bracket to frame bolts to 100ft-lbs/135Nm. They tend to come loose.

Don't worry bout the grease. It's an open pin/bushing that should be greased every 10hrs or so.

Old grease and dirt has to go somewhere. Either let it cling there, fall off, or wipe with a rag

But what you describe is normal. Basic part of ownership and greasing a pin/bushing

Thanks for the reminder, I was going to get this done this w-e. Is 100ft-lbs from the service manual? I saw 125 ft-lbs as a min recommended torque for M12 fasteners (which I believe these are ). Good either way, I'm sure 100 ft-lbs would prevent most issues anyway. The real key being checking them often.

I guess I expect the old grease to go somewhere, but i feel better seeing ooze out from each side of the bushing in the joint than on the front face. Feels like a better purge of old grease I guess.

Standard 10.9 M12 max torque is 105ft-lbs/140Nm dry:
