Caterpillar 321 Excavator
Cat 321 Series excavators are designed to handle the most rugged operating conditions, while providing long life and value. With a robust undercarriage acting as a solid foundation built tough to absorb the stresses of everyday work, the Cat 321 series can take on any project, large or small. Rollers and idlers are sealed and lubricated to extend service life, and track links are assembled and sealed with grease to decrease internal bushing wear and increase life by as much as 25%, when compared to dry seal undercarriages. The spring recoil system stroke has been increased to better relieve excess track tension, which can occur when material builds up between the track and sprocket. By using quality replacement parts when maintaining your Cat 321, you will insure it’s dominance as an earthmover when compared to the competition.
