516-2472 / 516-2470 Track Adjuster & Recoil Spring Group for Caterpillar Excavators
The 516-2472 and 516-2470 Track Adjuster & Recoil Groups are critical safety and structural sub-assemblies engineered for Caterpillar crawler excavators (such as Next Gen Cat 320, 323, and 330 series).
This assembly is primarily designed for 330 series hydraulic excavators:
· Excavators: 330, 330GC.
· System: It is a critical part of the undercarriage system, maintaining proper track tension and providing a recoil mechanism to protect the final · drive and track components from shock loads.

Why choose the SPARKLING NEW 516-2472/516-2470 Track Adjuster & Recoil Group?
-
- Pre-Compressed High-Tensile Coil Spring: Manufactured from silicon-manganese spring steel to provide immense compressive strength while preventing structural fatigue.
-
- Hard-Chromed Hydraulic Tensioner Piston: The internal grease ram features a micro-smooth, corrosion-resistant chrome finish to eliminate grease bypass and seal leakage.
-
- High-Durability Polyurethane Seals: Outfitted with robust, multi-lip sealing structures to keep structural grease locked inside the tensioning chamber under massive loads.
-
- Drop-In Interlocking Layout: Specifically aligned with Caterpillar assembly footprints, fitting securely into standard side-frame guidance channels without modifying tracking brackets.
FAQ
What are the primary warning signs that a track adjuster or recoil spring group is failing?
The most common sign is a tracking chain that repeatedly sags or throws completely off the idler wheels, even after pumping it full of grease (indicating failed internal hydraulic seals or a cracked grease valve). Other signs include a visibly broken or fractured coil spring, or a front idler wheel that "waddles" back and forth during tracking maneuvers because the adjuster barrel is bent or seized.
Can I safely disassemble an old 516-2472 recoil spring assembly to fix a seal leak myself?
No, you should never attempt to unbolt or cut a compressed heavy equipment recoil spring group. These springs are pre-loaded under thousands of pounds of mechanical force. Unbolting them without specialized industrial hydraulic press fixtures can cause the assembly to fly apart with explosive force, causing catastrophic injury or death. Always replace the unit as a complete pre-assembled group or have a certified undercarriage shop perform the rebuild.
How often should I check the track tension on my excavator?
Track tension should be checked daily or whenever moving the machine between drastically different jobsite environments (e.g., shifting from wet, sticky mud to dry, abrasive rock). In muddy conditions, clay packs into the sprocket teeth and track links, artificially tightening the chain, requiring you to vent grease out of the adjuster to prevent premature undercarriage wear.
