While you can repair a tire, you shouldn’t bother repairing a torn, gouged, or broken rubber track. Even if it’s just a temporary quick fix until you can be in a position to replace or just relocate the track it’s not a good idea or the safest thing to do.
For one, it is a pure waste of time and money. Once the track has had even the slightest of cracks, no amount of repairing can salvage the situation. The damage will continue to worsen. So, for instance, if the track has a split and you try to weave it in, the split will keep extending as the track gets around to the end when the equipment is moving.
Sometimes tracks become damaged due to an underlying issue with your machine. If you try to repair the track it’s possible you may not catch these problems.
Lastly, repairing a rubber track, especially by stringing two pieces, adversely affects the track tension. It makes the track lose, which affects the machine’s efficiency and productivity.
You might have watched a couple of DIY track repair videos on YouTube and think you can get it to “good enough” but you’ll certainly be taking a chance on it. While the creators mean well, what worked for them may not work out for you and your equipment. Plus you risk the safety of the equipment and the operator.
The only solution to damaged rubber tracks is to purchase good quality rubber tracks. You can DIY the track replacement or seek the assistance of a professional mechanic to replace the tracks for you.
Meanwhile, you could try selling the damaged or worn-out rubber track as scrap on eBay for a few bucks.
