New Ripper Teeth

[Lil Foot]

While using my Gannon a couple weeks ago, instead of ripping the earth asunder, it did it's imitation of cat scratch fever. I knew the ripper teeth were badly worn, so I broke down & ordered new ones from these folks:

I highly recommend them- friendly, helpful, & fast shipping.

I beat the snot out of the old teeth & they wouldn't budge. A few applications of PB Blaster overnight & they tapped off the next day. Heated the crimp area of new ones with a torch & did the new crimps with a 4lb sledge & a large ball peen hammer. Before the safety police jump my a$$, I put an aluminum "cup" over the ball peen, so no hardened face to hardened face contact.
1st pic shows how worn the old teeth were, 2nd shows the new teeth installed.

After those get worn down a little, get some "hardened" welding rods from tsc and weld the tips. You;ll probably never replace those tips again. Be prepared to do a lot of grinding to get the sharp edge back on them. When they say "hardened",, they mean HARD. I welded some teeth on a box scrape about 12 years ago, have not had to redo them or even sharpen them.
