Install a track repair link kit by releasing tension, removing the damaged link, preparing the pins and bushings, fitting the repair link and hardware, and checking torque before a test run. The job is a chain repair, not a bolt swap: the pitch must match, the pins must be clean, and the re-torque must be scheduled. Follow the OEM manual and use qualified personnel.

Tools and Safety Preparation for Chain Work
Gather the kit, a track bar, sockets, and the torque values for the hardware. Release track tension and block the machine before working on the chain, and confirm the kit part number against the chain pitch before the first bolt comes out.
Never work under a tensioned track. The forces in the chain are not something to fight by hand, and the release step is the safety step that the whole job depends on.
Tooling for Chain Work: What the Job Needs
Chain work needs the tools the manual lists: a track bar for aligning links, the correct sockets for the hardware, and a calibrated torque wrench for the final step. Improvised tools are where chain jobs go wrong, because the chain does not forgive a slipped tool.
Check the tool list against the kit before the machine is blocked. A job that starts with every tool on the bench is a job that can finish without a trip to the truck.
Removing the Damaged Link
Remove the damaged link section with the correct tools, keeping the surrounding links intact. Clean the area so grit does not enter the repair, and photograph the removed section for the record.
Inspect the links around the damaged section while it is out. If the neighbours show the same wear or damage, the repair point is wider than the kit, and the chain decision needs revisiting.
Keep the removed section until the new link is confirmed to fit, because the old part is the reference for the pitch and link type. A confirmed fit at the bench prevents a re-install at the machine.
Preparing Pins and Bushings
Inspect the pins and bushings at the repair point, and clean the surfaces that will carry the new link. Worn pins at the repair point mean the kit will not seat properly, and a seated kit on worn pins fails early.
The preparation is what separates a clean repair from a repeat failure. A few minutes of cleaning and inspection at this step save a second teardown on the same link.
Clean the pin bores and the link faces with the tools the manual specifies, and keep the repair area dry. Grit that enters the repair becomes the wear that the next service finds.
Fitting the Repair Link and Hardware
Fit the repair link into the chain, align the pins and bushings, and install the hardware. Confirm the kit part number matches the chain pitch before fitting, because a pitch mismatch will not seat and forcing it damages the chain.
Seat the link flush and check the alignment before torque. The link should match the neighbouring links on both sides, not stand proud or sit low.
Fit the hardware by hand first, then torque in the manual's sequence, because a link pulled down unevenly loads the pins on one side. The hand-fit step takes seconds and keeps the link true while the torque brings it home.
Torque and Seating Checks Before the Track Is Tensioned
Torque the hardware to the published values and rotate the track to seat the repair. Check that the link sits flush and engages the sprocket cleanly, and mark the bolts so movement is visible later.
The first rotation seats the pins and bushings, which is why the re-torque after initial use is part of the procedure. A repair that shifts or hooks needs investigation, not force.
Test Run and Re-Inspection
Run the track forward and reverse, then re-inspect the repair and re-torque after the first hours. The test run confirms the link engages the sprocket cleanly and the track rides without skipping.
Re-inspect the repair at the next service, not just at the re-torque. A repair that survives the first hours and the first service is a repair that will hold.
Confirming Pitch and Part Number Before the First Bolt
The check that prevents the wrong repair is done on the bench before the machine work: kit part number, chain pitch, and link configuration must agree. Provide the serial number and the old link part number to the supplier, and confirm the match in writing.
A kit ordered on the machine model alone is a guess that costs a teardown. The ten minutes of confirmation at order time is cheaper than the hour of rework at installation.
After the Test Run: Signs the Repair Is Holding
After the test run, check three things: the link is flush with its neighbours, the hardware has not moved past the marks, and the track engages the sprocket without a hook or skip. Each check is a pass or fail, and a fail means stop.
Record the repair with the machine hours and the kit part number. The record supports the re-torque schedule and gives the next service a baseline for the repaired section.
Re-check the repair after a full shift of work, not just at the re-torque. A link that holds through the first hours and the first loaded shift is a link that was installed correctly; the double check is what separates the repair from the repeat.
| Repair record field | What it captures |
|---|---|
| Kit part number and pitch | The confirmed fit for the repair |
| Installation hours | When the re-torque is due |
| Torque and re-torque result | Whether the hardware held |
| Link seating check | The flush fit at the repair point |
Safety note: chain work involves tension release and hardware torque — follow the OEM service manual for your model and use qualified personnel.
Common Mistakes
- Working under a tensioned track.
- Fitting a kit with the wrong pitch.
- Skipping the re-torque after initial use.
Conclusion
A repair link kit installs cleanly when tension is released, the pins are prepared, and the hardware is torqued and re-torqued. Check the fit and test the track before returning to work.

Frequently Asked Questions
Do I need to release track tension to install a kit?
Yes. Release tension and block the machine before working on the chain. Never work under a tensioned track.
Can I install a kit with the track on?
The track must be released enough to work the chain. Follow the OEM service manual for the procedure.
What torque should repair link hardware be set to?
Use the published values for the kit and machine with a calibrated wrench, and re-torque after the first hours.
