I have to replace the bushings/seal in the front support steering arm shaft on my wide front-end C. Has anyone done this before and can give me pointers? I can't seem to get the gear off the one end so I can slide the shaft out. I took the set-bolt out of the gear but it is still stuck on pretty good. Should I heat the gear up to loosen it? I tried a liquid wrench product to no avail. Also, does anyone know where I can get all of the bearings/seals/bushings for the front support? One place I tried did not carry the bottom bearing and seal. And another question - The manual says I should pack both the upper and lower bearings with No2 bearing grease, but when I put 250 gear lubricant in the box won't it fill into the lower bearing? Any help is appreciated.
