5. Install the front idler partially into the track frame. The front idler, the recoil spring, and the hydraulic track adjuster will be supported by the track frame.

6. Reposition the lifting straps in order to support the recoil spring and the hydraulic track adjuster (2) .

7. Remove four bolts (3) that hold the front idler to the recoil spring and the hydraulic track adjuster together.

8. Separate recoil spring and the hydraulic track adjuster (2) from the front idler. The front idler will be supported by the track frame.

9. The weight of the recoil spring and the hydraulic track adjuster as a unit is approximately 120 kg (265 lb).
