VIII. SERVICE AND MAINTENANCE

Leg Mounting Bolts

See page 97 for additional information regarding leg mounting bolts.

After changing hydraulic tread adjust bearings or adding or removing mounting shims, follow these procedures for torquing the leg mounting bolts:

Never remove more than three leg mounting bolts from any single leg mount.

Start the nuts on the mounting bolts and tighten them until they are just snug. Following the torque sequence in figure 8.49A, turn each lug nut to a torque value of 100 dry foot-pounds. Use slow, even pressure on the torque wrench. Quick or jerky movements cause inaccurate values.

Lower the sprayer to the ground and repeat the same sequence to 130 dry foot-pounds and again finally to 160 dry foot-pounds.

Resume operation and recheck torque

Jack Mount

Mounts to front or rear of the four legs, using two 1/2 x 2 1/2 inch bolts. Use a jack to lift machine up to remove the tire and wheel (Fig 8.49B).
