The Cat 303-5DCR uses 300x52.5wx90 rubber tracks (Width: 300mm, Pitch: 52.5mm, Links: 90). Always verify the size stamped on your existing track or use the TrackTECH Rubber Track Finder before ordering.

Matching drive sprocket options for the Cat 303-5DCR include CAT 303.5DCR Sprocket | Part #264-5371. When installing new rubber tracks, inspect sprockets for hooked, sharp, or uneven teeth because worn sprockets can shorten track life and damage the drive lugs.

Matching bottom roller or track roller options for the Cat 303-5DCR include CAT 303.5DCR Track Roller | Part #266-8793. Replacing worn rollers before installing new rubber tracks helps keep the undercarriage aligned and reduces uneven wear across the track carcass.

Matching front idler options for the Cat 303-5DCR include CAT 303.5DCR Front Idler | Part #267-4829. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.

Matching top roller options for the Cat 303-5DCR include CAT 303.5DCR Carrier Roller | Part #266-8794. Top rollers support the upper track path and should be checked for bearing play, flat spots, and uneven wear during undercarriage service.
