How do you check Caterpillar paver auger chain tension?
Uneven material delivery can involve chain condition, sprocket wear or an adjustment problem. Start with the specific paver's service procedure. Chain deflection values and adjustment points vary by machine, so this guide does not provide a universal measurement.
Observe before adjusting
Record whether the auger hesitates under load, makes a new noise or shows irregular motion. After shutdown and isolation, inspect the chain along its accessible length. Look for stiff links, damaged rollers, missing retaining parts and uneven tension. Inspect the drive and driven sprockets at the same time; a new chain on a damaged sprocket may wear rapidly.
Measure: use the location and method given for the installed chain assembly.
Compare: check both sides if the paver has separate auger drives, noting any difference in condition.
Decide: adjust only when the chain and sprockets remain serviceable under the manual's limits.
Ordering a replacement
Send the paver model, serial range, auger side and the exact chain reference. Note whether the chain is supplied as a complete loop or assembled from links, and identify related sprockets or tensioning parts separately. A chain described only by length can miss pitch, width or connector details.
Confirm machine-specific limits and procedures with the appropriate service documentation.
