How to attach ripper teeth

[brain55]

I use a press too. Too bad this is a 3 1/2 year old thread I could have let him know he went through a lot of trouble to put those teeth on upside down.

my question is, how do you get them off? mine are ground down and no longer sharp and need replaced.

Your new teeth have holes, well if the shank has matching holes, try what I do on my JD510 backhoe. JD uses steel/rubber sandwich pins that never stay in. My fix was to buy grade 8 bolts, drive it through the holes, then weld the head to the tooth. To remove a tooth, torch off the bolt head, hammer and punch the bolt out, beat the tooth off of the shank.

My dad's bachhoe used the dimple method where he'd heat the dimple area of the tooth cherry red, then put the round end of the ball peen hammer against it, and beat that hammer with a larger hammer. Usually one whack per dimple did the job. To get them off he had a chisel with the sharp end ground flat. He'd heat the dimples cherry read, then using the special chisel and hammer beat the tooth off the shank. If he was too slow, it meant reheating the tooth dimples.

I should have paid more attention to the postings details, yes it is over 3 yrs old, and yes the teeth are on backwards, a very common mistake.

I worked around metal shops in my youth and some iron workers and saw them strike smaller hammers with larger hammers without seeing a failure of either hammer face. It was one of the few times I witnessed those that rarely wear eye protection wearing eye protection. I don't recommend hitting hammer faces together, you never know when a failure will occur when striking two hammer faces together, especially when you are trying to knock the snot out of it. Hammers, especially ball pen and sledge typically have harden steel hammer faces and as a rule I try to use a a brass hammer or a hard plastic encapsulated dead blow hammer or even a piece of mild steel, brass or hard wood between two hardened hammer surfaces to prevent the fracture or splintering off either of the hammer's striking faces. As identified a press is easier to control and safer. I may be wrong with my safety caution and inevitably end up with grinding rock fragmenting and pieces of steel flying at me while heating or hammering but, I am the guy who use to get stuff in his eyes while wearing safety goggles.

I am looking at the teeth and I am thinking
"are they on upside down?"

Thought the Flat hardened steel was to enter the ground and
protect the bend in the shank?

Just thinking
