A track repair link kit is a pre-assembled solution for snapped excavator chains, enabling field repairs in under 2 hours without full track removal. The process involves aligning broken ends, inserting repair links and master pins, securing with hammer and punch, then retensioning and testing. AFT Parts OEM-specification kits fit CAT, Komatsu, Bobcat, and 20+ machine brands, priced $310–370 CAD with a 12-month warranty and fast Canada-wide shipping—saving contractors and mining operators $2,000+ versus dealer replacement.

What Is a Track Repair Link Kit and When Do You Need It?
A track repair link kit comprises pre-fabricated master links and connecting pins designed to rejoin snapped excavator track chains in the field. Common failure triggers include overload snaps from rocky terrain, pin walk-out due to vibration, and accelerated wear in harsh Canadian conditions—frozen ground in Saskatchewan, rocky Alberta oilfields, or coastal BC logging sites. AFT Parts kits are manufactured to OEM specifications for 20+ brands including CAT, Komatsu, Kubota, Bobcat, Hitachi, John Deere, Kobelco, Case, Doosan, and others, priced between $310–$370 CAD.
Field-ready repair kits eliminate costly downtime. Instead of waiting for a dealer replacement chain (often 5–10 business days and $2,500–$4,500 CAD), operators use a kit to restore mobility on-site. This is critical for remote mining operations, seasonal agricultural contractors, and equipment rental fleets where equipment unavailability directly impacts revenue.
Can Field Repairs Save Canadian Operators Time and Money?
Yes. A track repair kit plus 2 hours of labor costs $500–$800 CAD total, compared to full chain replacement at $2,500–$4,500 CAD plus 12–24 hours of downtime. For B2B buyers—Ontario rental fleets, Saskatchewan mining contractors, and Quebec quarry operators—avoiding downtime translates to retained client contracts and continuous billable machine hours.
| Scenario | Repair Kit Route | Full Replacement Route | Savings |
|---|---|---|---|
| CAT 320 Excavator | $650 (kit + 2 hrs labor) | $3,200 (chain + 16 hrs labor) | $2,550 |
| Komatsu PC400 | $720 (kit + 2 hrs labor) | $4,100 (chain + 20 hrs labor) | $3,380 |
| Bobcat E35 (compact) | $580 (kit + 1.5 hrs labor) | $2,800 (chain + 12 hrs labor) | $2,220 |
AFT Parts repair link kits leverage this efficiency gap. With in-stock inventory across all Canadian provinces and free ground shipping, operators can order a kit online and receive it within 24–48 hours—avoiding the shipping delays common with US or overseas suppliers.
Which Tools and Safety Gear Are Essential for Track Repairs?
Essential tools include a hydraulic jack or track breaker, punch set, sledge hammer, and track tension gauge. Personal protective equipment requires heavy-duty gloves, safety goggles, and steel-toed boots. Always depower the machine, engage hydraulic locks, and chock the opposite track before work begins.
- Hydraulic jack: Lifts undercarriage to break track tension safely
- Punch set and sledge hammer: Drives master pins flush and peens ends
- Track tension gauge: Ensures retensioning to OEM spec (prevents re-failure)
- PPE: Gloves, goggles, chocks, and backup personnel for heavy lifting
- Cleaning supplies: Wire brush to remove debris from broken chain ends
AFT Parts recommends downloading a free field readiness checklist (available via WhatsApp or email) covering all tool requirements and safety protocols specific to your machine brand and model.
How Do You Install a Track Repair Link Kit Step-by-Step?
Step 1: Prepare the Machine
Power down the excavator completely. Engage all hydraulic locks. Position a hydraulic jack under the track frame and raise the undercarriage until the snapped chain sections lift free of ground contact. Chock the opposite track with wooden blocks or wedges to prevent accidental movement. Position personnel at safe distances.
Step 2: Remove and Inspect
Carefully separate the two broken chain ends by rotating the excavator's drive sprocket (or using a breaker bar on the track frame). Inspect both ends for cracks, bent links, or frame damage. If frame cracks are visible, a full track replacement may be necessary. Clean both ends with a wire brush to remove dirt and debris, which can interfere with pin seating.
Step 3: Insert the Repair Links and Master Pins
Position the AFT repair link kit components between the broken chain ends. Align the master pin holes carefully—misalignment causes rapid re-failure. For CAT machines, the master pin typically seats from one side; for Komatsu and Bobcat models, consult the kit documentation for your specific brand. Slide the master pin through aligned holes until fully seated.
Step 4: Secure with Hammer and Punch
Using a punch and sledge hammer, drive the master pin flush against the track link body. Strike firmly but controlled—excessive force can bend the pin or deform the link. Peen the pin end if required (CAT kits often include a peen requirement; Komatsu kits may not). AFT Parts kits include brand-specific installation guides for each machine series.
Step 5: Retension and Test
Lower the hydraulic jack slowly until the track contacts ground with light tension. Use a track tension gauge to verify tension matches OEM specification (typically 40–60 mm deflection mid-span, depending on machine). Operate the excavator at low speed for 10–15 minutes, monitoring for vibration, noise, or visible movement at the repair joint. If all systems pass, resume normal operation.
What Are the Risks of DIY Repairs and How to Avoid Them?
Common DIY failures stem from improper pin seating (causing rapid re-failure under load), overtensioning (damaging carrier rollers and idlers), and using non-OEM kits that don't match original specifications. Cheap imports or generic kits introduce dimensional inconsistencies—a problem especially critical in remote Canadian mining sites where replacement parts may be days away.
Mitigation strategy: purchase OEM-specification kits from AFT Parts, which manufactures to exact original tolerances. Every AFT kit includes a 12-month pro-rated warranty. Pre-repair inspection for frame cracks or bearing wear is mandatory—a repair kit cannot fix structural damage. If cracks are detected, contact AFT Parts support (WhatsApp +1-236-965-6529 or support@aft-parts.com) for guidance on whether repair or replacement is appropriate.
