Finally got to my zerks today on my 27 hr 2610. Ever since I first did zerks on my 47 Ford 1 ton...50 years ago have always hated the dam things. This was my first try with a locking attachment for the end of the flexible hose and like I figured it hardly made the job any more easy. I guess there are none under the tractor which is nice. But, I am a big fan of sealed anything that involves dirty petroleum products of any kind. And as a mechanic. believe it or not, among many other things, I have done my share. The loader seemed to work smoother after the job, or was that just wishful thinking?
