1. Remove the bottom guard below the main valve. Move the drain hoses from swing bay area in order to avoid interference with the tooling.
2. Remove and replace the 8T-5878 Bolts one at a time in an alternating sequence. Refer to Image1.1.1 for the sequence.
Refer to Image1.1.2 for the required tooling. For the bolt removal a 3/4" impact with swivel and 36mm socket is required.
3. When replacing the bolts, apply a general-purpose adhesive/sealant for locking and sealing the screws and nuts in place (Loctite 242 or 243) to the bolts, before installing. Do NOT clean out the threads before installing.
4. Tighten each bolt to a specified torque of 900 +/- 100 N.m (665 +/- 75 lb ft).
Refer to Image 1.1.3 for the required tooling.
For installation, a 132-8112 Hydraulic Wrench, if available, or the updated serviceable 384-8910 Hydraulic Wrench. An equivalent hydraulic wrench with a 3/4" Sq Drive, with a torque range of 140 - 1400 ft/lbs and similar size and dimensions for access.
