Indexing a New Style Bull Gear

This procedure will work on all machines with a rotatable bull gear.  The pinion should be changed whenever you rotate the bull gear.

  1. Stop the machine just as the pallet receiver frame starts up. Turn off the power. Let machine drift to a neutral position (see Figure 1).

Figure 1

  1. Lock out machine main panel.
  1. Remove nuts and lock washers from bolts which hold bull gear to the hub. These are the unpainted bolts (see Figure 2). There are six bolts on a V3-12 and eight on the Dynapac and larger machines.

Always maintain a safe work area that is free from slipping and tripping hazards.

Always be sure appropriate safety devices are used when providing maintenance and repairs to all equipment.
