BobCat E35 – SWING CIRCLE GEAR – Swing Bearing Installation

If reusing the existing swing bearing, use the alignment marks to put the swing bearing in the correct location. If installing a new swing bearing find the inner race soft zone (Item 1) and outer race soft zone area (Item 2) [Figure 30-40-2].

Install the swing bearing so the inside soft zone (Item 1) is at the left hand side of the excavator and the outside soft zone (Item 2) [Figure 30-40-2] to the right side of the excavator.

NOTE: Do not put the soft zone to the front or rear of the excavator.

Install the swing bearing bolts (Item 1) [Figure 30-40-3] and nuts.

Tighten the bolts in the correct sequence (#1 to #24) to 105 – 115 N•m (78 – 85 ft-lb) torque [Figure 30-40-4].
Retorque bolts (#1 to #4) after all bolts have been torqued.
Put lubriplate grease or equivalent on the swing bearing gear.
