The marker arm is attached to marker body with a 3/8-
inch, grade 2, shear bolt. If this shear bolt breaks,
replace it with a grade 2 bolt.
NOTE: Failure to replace the shear bolt with a grade
2 bolt can cause marker damage.
If grease-seal cap for marker-disk-hub bearings is
damaged or missing, disassemble and clean hub.
Repack with grease and install a new seal or grease
cap.
