So I let my 955 12A track loader set out for about a year and a half and when i started it, the steering levers are frozen up. They are free on the cross shaft but they won't actuate the steering clutches. 

I don't know if the clutches are stuck in the drum or what.

More than likely it's the linkage pivot bearings that are froze up, the ones you can't get to to lube although you can access the upper ones by removing the cover.

I think I'll take off the top cover tomorrow and see what's going on in there...I have a parts book coming from Ebay. I guess the upper ones are lubed by zerks that I see on top of the cover.

My danged clutch lever is seized up on the cross bar too...I can heat it up and get it to working but 5 minutes later it's seized again. It's not turning the cross shaft, the brake pedals are working fine.

If it has zerks in the cover someone has added them. Problem is there is an air gap between the cover and the pivot bearing so unless there is some type of coupling (big fat 0-ring maybe) the grease would not penetrate the bearing.

Yes OM, I see the grease zerks are not on the cover but mounted ahead of the cover.

I'm going to pull that cover and see if I can get some penetrant in there...and go from there.

Thanks to you and Daryl.

Unfortunately, under the right weather conditions those compartments can be real rain makers as far as condensation goes.

Well, I get to pull the top cover it looks like...fantastic.

I guess I'll rebuild the clutches while I'm in there and check the bevel gear bearings, they've always been suspect.

But first I'll need to spend 40-50 hours removing the loader assembly.

But I'll need to rebuild this 1586 IH tractor engine before I can make enough room in my shop.

Apparently if you strip everything flat you can get the cover out of there without removing the loader.
