Disc grease housing

I have an old vintage disc that I m fixing for small jobs. There are no actual bearings on the 1" square axle, but rather a machined 6-7 inch spacer that the two halves of the bearing housing enclose. My issue is that the grease tube that feeds grease to the inside of the housing is rusted out $ grease never gets inside where it is needed. The Housing is stamped PA 4150. I do not know the brand of disc. It was free, rusty and abandoned. I use it for small jobs, plots & weed control. Is there a workaround or part available? Thanks

Not sure why you need such a long pipe? Can't you screw a zerk right into the bearing hosing and grease it that way? If you need the pipe extension just get a nipple and coupling the right size, looks like 1/8 pipe, maybe 1/4, most grease zerks are either one or the other.
 
That fitting looks like what was in an old very old Massey Harris disk I had. It was 1/4" pipe thread instead of the normal 1/8" pipe thread. You could a couple of years ago buy the 1/4" fittings but you needed a short pipe nipple and a coupler. You could if it is the 1/4" do like above but screw in a 1/4" to 1/8" reducer for a standard fitting. If the 1/8" fitting just get a 1/8" pipe and coupler. The spout on your greae gun is 1/8" pipe. Does the disk have a crank for adjusting gang angle? If yes look on the casting at top where the crank goes through, may be a marknig there. Mine was the Massey Harris and that marking was the M & H put together with the right side of the M being the left side of the H. Just going on what that fitting looks like . The New Idea 3 and 4 bar rakes used one of that style greae fittings. But I have never seen somebody trying to put a lock nut on a grease fitting. It should tighten in good without that lock nut. If problems with tightening just use some locktight.
