BRACKET AS 2724880 - Caterpillar

Connect one end of come-along (11) onto the hook on the outside stand. Connect the pulley hook on come-along (11) to the plate that is below the tube on the outside of the undercarriage. Connect the third hook of come-along (11) onto the pin on come-along (11).
Ratchet come-along (11) in order to pull the undercarriage along the tube. The undercarriage is slightly heavy toward the rear of the undercarriage. You will need to pivot the undercarriage so that the grousers do not drag on the ground.Note: On some machines, you may need to help the drive wheel off the pilot surface on the rear axle.
Move the undercarriage until you have an adequate working area between the undercarriage and the machine. Note: Spacers with dowels and with through holes may stay with the undercarriage when you remove the undercarriage. Make sure that the spacers with dowels stay with the machine on the guide bolt.
Remove the guide bolts.
Three clearance holes are provided in the drive wheel spacer to accommodate the three socket head screws that fasten the drive wheel to the hub. When adding spacers, make sure that the clearance holes in the spacer are positioned correctly to accommodate the drive wheel hub socket head screws.
Remove spacers for the drive wheel and/or spacers for the hardbar or install spacers for the drive wheel and/or spacers for the hardbar. See the Special Instruction, SEHS9982, "Procedure to Change the Track Gauge" for the following components that are required for the gauge: spacers, bolts and belts.Note: Some widths of spacers for the drive wheels use temporary bolts. Pay attention to the orientation of the drive wheel and of the spacer in order to allow proper alignment of the holes for the temporary bolts. Note: Some gauges use a combination of spacers with flanges and spacers with through-holes. When you install a combination of spacers, place the spacer with through-holes between the spacer with flanges and the undercarriage.Note: Before starting the installation procedure, clean the mating surfaces of the spacers, hardbar, flanged rear axle, and undercarriage. Also clean all bolt threads and holes. Add lubrication to the bolt threads and under each bolt head. Engine oil or any other anti-seize compound may be used. If you install spacers with dowels in the hardbar, clean the holes for the dowels. Note: The flanged, rear axle and spacers with flanges for the drive wheel have a pilot surface. The pilot surface centers the drive wheel to the flanged, rear axle or to the spacer.

If you did not install guide bolt (12) into the hardbar or into the spacer for the hardbar, install guide bolt (12) into the top, center hole of the hardbar or into the spacer for the hardbar.
Install dowel pins if the dowel pins are required.
Install another guide bolt (12) into the top, center hole of the flanged, rear axle or into the spacer for the rear axle.
