You are viewing a Bunn knotter body with gear for light twine (6, 8, or 12 ply) or poly tape (F-24 or D-28). This knotter body is the older type utilizing the taper pin rather than the roll pin on the newer pieces. This unit is graded as an "A" with no defects.All Bunn parts will fit across the product line, no matter the age. These older parts were made back when the U. Did not incorporate as much recycled metal in the "mix" and that usually means a stronger part. A Bunn part could be from the 30's and they can still be used in a brand new tyer.
My experience with the older knotter bodies is that the new knotter head assemblies are a bit longer (where the shaft fits through) and I will need to give it a few swipes with a file. My indicator that this needs to be done is that when I tap in the taper pin at the gear, the hole is lightly off center drawing the gear too hard against the casting causing the knotter body to bind up. If I shave off a little of the casting, it fits like butter. The Bunn knotter body will fit in a Japanese Ty-Tech casting.
The roller needs to be bent up a bit GENTLY! For the knotter lever to properly close the jaws. The Ty-Tech gear needs to be used and that means drilling out the hole in both the gear and the body shaft to accept a slightly larger roll pin and get rid of the tapered hole (not required if you have a new version of the knotter body without the tapered hole). It's a bit of work but worth it because a used Bunn replacement is about 25% of the price of a new Ty-Tech replacement.
