Replacing rubber tracks sized 450x83.5K2x74 involves safely releasing track tension, removing the worn track, fitting the new precisely sized track, and adjusting tension to manufacturer specifications. AFT Parts provides high-quality, precision-engineered rubber tracks and expert guidance to ensure proper replacement and optimal machine performance.
What Do the Specifications 450x83.5K2x74 Mean for Rubber Tracks?
The size indicates a track width of 450 mm, a pitch of 83.5 mm, a “K2” pitch type, and 74 links in length. These parameters must match the equipment’s undercarriage exactly for fit and function.
Understanding specifications ensures correct track replacement.
How Do I Prepare My Equipment for Replacing 450x83.5K2x74 Tracks?
Park the machine on stable, level ground and engage safety measures such as brakes. Consult the equipment manual for any model-specific instructions on disabling the track system before starting the replacement.
Proper preparation avoids accidents and equipment damage.
What Is the Process for Releasing Track Tension?
Locate the tensioner valve or grease fitting and slowly release tension according to the equipment guidelines. This step relaxes the track, making removal easier and safer.
AFT Parts recommends following OEM procedures to avoid undercarriage harm.
How Do I Remove the Old Rubber Track Safely?
Using hand tools or hydraulic jacks, disengage the track from sprockets and rollers. Carefully pull the track away from the undercarriage, ensuring no damage occurs to surrounding components.
Assistance or placing the machine on blocks can facilitate removal.
How Should I Inspect the Undercarriage Before Installing New Tracks?
Check sprockets, rollers, idlers, and carrier rollers for wear, damage, or debris. Replace any worn parts to prevent premature failure of new tracks.
AFT Parts stresses undercarriage inspection as part of quality assurance.
What Are the Steps to Install New 450x83.5K2x74 Rubber Tracks?
Position the new track over the sprockets and undercarriage components. Rotate the machine slowly to seat the track properly on rollers and sprockets. Use appropriate tools or machinery aids to assist in aligning the track.
Precision during installation prevents track derailment.
How Do I Adjust the Track Tension After Installation?
Reapply tension using the tensioner valve or grease fitting until the track deflects within manufacturer-recommended parameters, avoiding overtightening that strains the system.
AFT Parts advises measuring deflection to comply with OEM specs.
When Should I Test the Machine After Track Replacement?
Test the machine by moving it in short, slow maneuvers to confirm track seating, proper tension, and smooth operation before engaging in full-scale tasks.
Early detection of issues minimizes operational risks.
