(1) Final Drive Sprocket
(2) Front idler wheel Note: The approximate weight of the track is 247 kg (545 lb).
Use a suitable lifting device. Lift the track at middle position between the front idler and the final drive sprocket until the front idler collapses fully. Note: It is helpful to support the bottom of the track in order to maximize the slack between the front idler and the drive sprocket.
Keep the track supported with a hoist. Lift the track over the flange of the front idler so that the inner track guides clear flanges.
Lift the track over the sprocket with a suitable lifting device. The inner guides need to clear the sprocket teeth.
Lift the track over the rear idler. The inner track guides need to clear the rear idler. Installing the Track
Note: The approximate weight of the track is 247 kg (545 lb).
Use a suitable lifting device. Slide the track onto the rear idler so that the inner track guides straddle the rear idler. If your machine is equipped with an idler with dual flanges, the inner track guides must seat between the flanges.
Pull the track forward in order to ensure that the track guides are fully seated on the rear idler.
Lift the track over the final drive sprocket so that the inner track guides straddle the sprocket teeth. The sprocket teeth should seat in the openings in the middle of the track.
Pull all of the slack forward. This will provide the maximum amount of slack to aid with installation across the front idlers. Note: It is helpful to support the bottom of the track in order to maximize the slack. This will help with installation.
Position the track so that the inner track guides seat between the flanges on the front idler.
Tension the track. Refer to Operation and Maintenance Manual, "Track - Inspect/Adjust" for the procedure.
