threaded pocket. Firm up the low-pro pocket bolts until pockets are firm on the
wheel. Do not tighten then down yet.
7.
Rotate the wheel until you come to the next set of straight teeth.
Repeat steps 2 – 6.
8.
Next, replace the angle pockets (angles face away from the wheel).
9.
Remove 1 set at a time or all old angle teeth and pockets at once. Clean the
wheel with a wire brush.
10.
Install your low-pro pocket bolt through the holes in the counterbored pocket.
Apply anti-seize. Slide the low-pro pocket bolts through the holes in the wheel.
Make sure the counterbored pocket is on the right hand side of the wheel.
Insert the low-pro pocket bolts into the threaded pockets and tighten the
pockets firmly onto the wheel. Repeat this step until all your standard angles
pockets are installed.
Installing teeth
1.
If all the counterbored pockets are on the right hand side of the wheel, your
tooth will go into your pocket properly. If your pockets are mounted upside
down, the teeth will have a tendency to spin freely or be sloppy in the pocket.
You will know this by looking at them.
2.
Install your teeth with the carbide facing down. The shoulder of the tooth will
meet the flat detent of the pocket and the tooth will not rotate. Thread nut onto
the top portion of the tooth. Hand tighten for now. Repeat until all teeth are
installed.
Torque
1.
Torque the low-pro pocket bolts to 245 – 325 Nm.
2.
You will notice the slotted end of the low-pro pocket bolt is about 3 mm short
of the end of the threaded pocket. This is okay. This area will fill with dirt and
protect the extraction slot at the end of the low-pro pocket bolt. If you need the
slot, clean out the packed dirt and use the slot to turn out the broken bolt.
3.
To torque your tooth down, tighten the top lock nut until the tooth is firmly
seated. (See Torque Settings table below). Double check that the tooth is firmly
seated. Do not over tighten. Over tightening the nut will stretch the threads
and make it impossible to ever tighten again.
4.
Once the low-pro pocket bolts, teeth and nuts are seated and torqued properly,
cut a few stumps. Recheck bolts and nuts to make sure they are tight and
secure. Recheck frequently for the first week of use and once a week
thereafter.
When you dull or damage a cutting edge, loosen the top nut, tap the tooth down,
rotate the tooth a third of a turn and tighten back up.
