the hydraulic pump.
2. Extend the packer until the top rollers are at the same height as the bottom rollers were in the
previous procedure.
3. Lock out and tag out the vehicle (see Locking Out and Tagging Out the Vehicle on page 12).
4. Replace both top rollers (one at a time):
4 a. Using a 5 ⁄ 16-inch Allen wrench and a 3 ⁄ 4-inch box, remove all 4 bolts that keep the roller in
place (see Figure 3-60).
4 b. Remove the roller assembly and replace it with a new one.
4 c. Put back all 4 bolts in their respective holes before tightening them up.
