Track sagging or jumping on your 330GC? A weak or leaking 516-2471 track adjuster cylinder can no longer maintain the tension needed to keep the track chain correctly engaged with the sprocket and idler, causing rapid track component wear. RITO supplies this complete track adjuster cylinder with recoil spring to restore correct track tension and protect undercarriage life.

In Stock516-2471 Track Adjuster Cylinder with Recoil Spring Assembly for Caterpillar 330GC, 330GCL, 330 and 330B excavators. Cross-reference: 516-2469. The track adjuster maintains correct track chain tension by pushing the front idler outward via the cylinder-spring mechanism. The recoil spring absorbs sudden track tightening from rock ingress, protecting the idler and chain from shock overload.

Recoil spring rated to 330GC OEM pre-load specification so the front idler maintains correct track tension across the full operating load range without over-tensioning the chain.
Cylinder rod chromed and honed to OEM specification; seals rated for hydraulic grease pressure, preventing the slow adjuster leak that causes progressive track sag.
516-2471 cross-references to 516-2469 for 330-series variants; confirm the applicable cross-reference for your specific machine variant before ordering.
Recoil spring compresses under sudden track tightening from rock ingress, protecting the front idler bearing and track chain link from the shock load that causes premature component fracture.
FAQ
Q: How do I know when the 516-2471 track adjuster needs replacing on 330GC?
A: Track chain sag exceeds the OEM specification measured between the carrier roller and the lowest track link, front idler moves back and forth noticeably under load, grease leaking from the cylinder rod seal, or the adjuster cannot hold track tension after pumping.
Q: Should I replace the track adjuster and front idler together on 330GC?
A: If the front idler bearing or flange shows heavy wear, replace both together. A worn idler will quickly re-wear a new adjuster cylinder rod by transmitting shock loads beyond the recoil spring rating.
Q: What grease should I use to adjust the 516-2471 track tension on 330GC?
A: Use lithium-based grease injected through the zerk fitting as specified in the Caterpillar 330GC operator manual. Never use oil in place of grease; it cannot maintain the adjuster pressure required for correct track tension.
Q: How to confirm 516-2471 fits my 330GC?
A: Match the existing part number 516-2471 or 516-2469 and confirm the machine model is 330GC, 330GCL, 330 or 330B. Provide machine serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
