8” x 2” bolt and locknut. Place one 5/8” x 2-1/4” bolt and locknut in the remaining set of holes through the
stabilizer braces.
5. Fasten the upper lift arms to the axle: use an axle frame pin, a 1/2” x 1-1/2” GR8 bolt and a 1/2” locknut on
each side. Tighten securely.

b. Add the track shoe bushing and then secure the bushing with a 7/16” x 3-1/2” bolt and locknut. Tighten
securely.
8. Attach upper lift arms to the lift assist bracket as follows:
a. Raise and position the top of the upper lift arms on the pin weldments on either side of the lift assist.
b. Secure the upper lift arms on the pin weldments using a upper lift arm bushing, a washer, a 7/16” x 3-1/
2” bolt, and a 7/16” locknuts on each pin weldment.
c. Tighten securely.
9. Lower upper end of auger slowly until track shoe rests against upper track stop and the lift assist stops rest
