All dimensions are referenced to the centerline of the hole.All dimensions are in millimeters. (12) Boss.
Mount boss (12) in the location that is shown in Section "A-A" of Illustration 3. Weld the boss in place. Weld using standard welding procedures. Use low hydrogen electrodes or equivalent GMAW or FCAW processes. Welds should be of good quality and free of obvious defects.
Illustration 4 g01132851
All dimensions are referenced to the centerline of the hole.All mounting dimensions are in millimeters. (6) 9C-7929 Block . (12) 9R-2640 Boss .
Mount boss (12) in the location that is shown in Illustration 4. Weld the boss in place. Weld using standard welding procedures. Use low hydrogen electrodes or equivalent GMAW or FCAW processes. Welds should be of good quality and free of obvious defects.
Mount block (6) in the location that is shown in Illustration 4. Weld the block in place. Weld using standard welding procedures. Use low hydrogen electrodes or equivalent GMAW or FCAW processes. Welds should be of good quality and free of obvious defects.
Install the mounting brackets and the clamps on the accumulators. Hand tighten the nuts and the bolts.Note: Do not torque the nuts and bolts. This will be the last step in the subassembly.Note: In order to prevent leakage, follow the procedure that is listed below.
Lubricate the fittings and preassemble the fittings. Hand tighten the fittings. Do not torque the fittings.

Tightening Sequence of the Fittings
Install the fitting assembly on the accumulators by alternately tightening the two elbows. Torque the fittings at the accumulators and work outward toward the hose connection. Use Illustration 5 to determine the sequence that you should tighten the fittings. The numbers that appear on the fittings represent the tightening sequence.
Torque the mounting bracket and clamp the nuts and the bolts.
Install the ride control accumulators, the brackets and the fitting assembly on the machine. Connect the hose.
Install the remaining parts to the system. Use Illustration 1 for reference. Install the reused hose clamps on the hoses in the locations that are shown.
Charge the accumulators to 3800 kPa (550 psi). Adjust the accumulators, if necessary. Refer to Testing and Adjusting, "Ride Control Accumulator - Test and Charge" for more information.
