HOSE AS 2679742 - Caterpillar

Check the nitrogen precharge pressure.Consult your Caterpillar dealer for the correct test procedure, and the recommended pressure. The machine is shipped from the factory with the accumulator uncharged. Have it charged before machine operation.Suspended Axle Accumulator (If Equipped)
Check Precharge Pressure
Located at the rear of the tractor on the right side. Check the nitrogen precharge pressure.Consult your Caterpillar dealer for the correct test procedure and the recommended pressure.Cutting Edges and Router Bits
Change or Rotate
Lower or block the bowl when performing maintenance in the bowl area.Support the cutting edges before removing the mounting bolts.
Do not attempt to increase wear life by welding on cutting edges. This could result in premature failures.Change or rotate the cutting edges or router bits, before the mounting surfaces become worn.
Cutting Edges
There are two edges to each section. Double wear can be obtained by rotating each edge 180°. By exchanging sides, the two end sections can be used four times. 1. Support the cutting edge and remove the mounting bolts.2. Remove the edge.3. Clean all mounting surfaces.4. Change or rotate the cutting edges. To align the cutting edges for finish work, use the front mounting holes in the center section.If better penetration is required, extend the center edge forward by using the rear holes for mounting.5. Install the new or rotated edge and all of the mounting bolts.6. See "Ground Engaging Tool Bolt Torques" for the correct bolt torque.Router Bits
1. Double wear can be obtained by rotating and installing the router bits on opposite sides. 2. Remove the router bit mounting bolts. Remove the bits.3. Clean all mounting surfaces.4. Install new or rotated router bits. See "Ground Engaging Tool Bolt Torques" for the correct bolt torque.Elevator Chain
Adjust
Measure the slack of each chain from the bottom of the elevator frame to the top of the bottom chain loop. Measure midway between the sprocket and the idler.The distance should be 28 to 36 cm (11 to 14 in) with not more than 5 cm (2 in) from one side to the other. Adjust the chain, if necessary, as follows.Consult your Caterpillar dealer for correct procedure and replacement parts. 1. Attach one end of the jack to the elevator frame. Connect the other end to the adjuster roller bracket. 2. Remove the bolt from the adjuster arm. Operate the jack as required to loosen or tighten the chain. 3. Install the bolt through the hole in the adjuster arm and a hole on the elevator frame.4. Remove the jack. Use it to adjust the opposite side chain, if necessary.5. After use, store the jack on scraper push frame, under the cover plate. If proper chain adjustment cannot be obtained, replace a roller and connector link with an offset link on both chains at the same location. Measure length of chain over 10 links, if over 1071.2 mm (42.12 in) both chains should be replaced.Replace
Measure the length of 10 links. If the dimension is 1091 mm (43.0 in) or more, install a new chain. Also, replace the chain if breakage
