Shear Pin - Walinga Grain-Vac 7614F Operator's Manual

5.2.4 SHEAR PIN

Each PTO driveline is equipped with a shear
bolt on the machine end of the driveline. It is
used to protect the Grain-Vac from overloading.
When replacing the shear bolt, follow this
procedure:
1. Clear the area of bystanders, especially small
children.
2. Place all controls in neutral, stop the engine,
set the park brake, remove the ignition key
and wait for all moving parts to stop before
dismounting.
3. Remove any remaining bolt parts from the
yoke assembly. It may be necessary to use a
hammer and punch to remove the old parts.
Be careful not to enlarge the holes.
4. Shear bolts can be replaced with a standard
shear bolt with UNC thread. Check with
Walinga's Engineering Department for the
proper size for your year and model.
5. For the size of the shear pin for the single pin
and the double pin assembly contact the
Walinga Engineering Department.
