Found an older but heavy duty 12" bit 3pt PHD earlier this year to do some immediate holes and for the future. When I got it, the gear box seemed very tight and other than a slight bend in the arm seemed good. Went to check/fill the gear box with gear oil and the shaft seal for the auger was leaking pretty good.
I did the 3 holes I needed for a cottage addition and other than breaking numerous shear pins and widening the already too wide hole for the shear pin, it worked well.
Before anything I filled it with diesel to clean up the inside gear box. I let it sit upside down for a few days to hopefully clean any sludge from everything
Finally got around to the repairs. After taking it apart, just the main arm from the gear box and the auger off (didn't take the gear box apart as it seemed good).
The shaft seal was an older type and new I wouldn't be able to find an original part...so how to adapt
Found a standard 1.5" trailer axle seal for about $7 and now how to adapt. The millwrights were busy at work, so i found a local machine shop to mill a 1.5" hole half way into an appropriate sized 1/2" piece of steel to the depth and OD of the seal.
The rest even with my welding skills was fairly easy...
Dry Fit
Welded
Although not in a real augering job, the new seal is good with no leakage. Easily replaceable, although I bought a few spares to have around.
The next repair was the auger bit itself where the years of wear had widened out the 3/8" holes for the shear pin. I cut 2 small pieces of 1/2" steal with 3/8" holes already drilled and carefully lined up the existing holes and welded them on.
Final Pics - Minus the touch up paint from marrs putting it back together
So far looks good other than the seal on the other shaft has a very slight drip although i may have slightly overfilled the gear box.I will drain some off and recheck.
Enjoy Dave
