8.Insert the blow gun tip into the shear pin hole, blow out the hole with compressed air, then put a drop of oil in the hole.
9.Insert the new shear pin into the bore, as shown in Figure 143.
Note: If the pin does not freely slide into the bore, DO NOT use a hammer on the pin or you may permanently damage the shear mechanism and bore, which would make it nearly impossible to remove if it breaks again. Instead, take the time to carefully line up the two bores so it slides in easily. Chamfer the end of the pin if necessary to make it easier to insert.
