12.3 Replacing Points & Shear
Pins
How to Replace Points
When points become worn or damaged it is
necessary to replace them. This can be done
without removing the tines from the Deep
Digger.
Removing the point:
1.
Raise the point off the ground.
2. Knock out the roll pin.
3. Remove the point and replace with new
point and roll pin.
How to Replace Shear Pins
When shear pins break it is necessary to
replace them:
1. Removing the broken pin from the frame.
This may require a hammer and punch.
2. Align the rear shear pin vee of the tine
with the holes in the frame assembly.
3. Fit the shear pin and lock the pin into
position with the clips provided.
It is important that you use only the correct
and specified replacement shear pins. See
Section 13 for further information.
