PARTS NEEDED

| No parts needed for this program |
ACTION REQUIRED
Show/hide table
| Review, understand, and adhere to all safety and environmental warnings and notices associated with positioning the machine for rework and the swing bearing bolt torquing procedure. The machine should be on a level surface with the front linkage extended and resting on the ground to achieve the best zero mechanical loading of the swing bearing bolts as possible. Using a calibrated torque wrench, either manual or hydraulic, or a torque multiplier, tighten all the bolts in the circle that joins the swing bearing to the carbody top ring (the inner-most circle of the two, those with the long spacer). For 324D, 325D, and 330D machines, tighten the bolts to a torque of 900 +/- 100 Nm. For 345 machines, tighten the bolts to a torque of 1000 +/- 125 Nm. Mark the first bolt tightened and continue radially until all bolts have achieve the desired torque value. |
