The best way to keep your heavy-duty excavator's parts functioning at an optimal level is through maintenance with the right spare parts. Having quality replacement parts that meet or exceed the manufacturer's original specifications will extend the life of your excavator.  

So, when you consider replacing it with caterpillar parts and cat undercarriage components, it will help you remain prepared for an extreme environment. In fact, their attributes can help you have your large applications working at its best without any issues.  

To help you make the most of the products you choose, this guide provides an overview of all of the important components associated with the heavy duty excavators.

Why spare parts matter

The rugged work environment that excavators operate in can cause component wear and tear. This is due to constant exposure to dirt, debris, and vibrations while you are using it for your specific needs. When excavators are not properly maintained with top-quality OEM or aftermarket spare parts, the machine will eventually lose power and precision of the application in no time. 

However, the use of top-grade products at a fair price will keep your excavators running for years. By utilising regular maintenance and replacement, you can save an average of 30% in repair costs and avoid costly emergency trips to the repair shop. This allows you to maintain maximum productivity with your operators.

Undercarriage basics

Half of your excavator’s wear is attributed to its undercarriage, while most of the impact from rough ground is borne by its tracks and rollers. A daily cleaning regimen allows for early detection of cracks.

Take a look at the components that can help you with mobility are:

• Track Chain, 

• Track Shoe, 

• And Idler Assemblies. 

A failure to properly maintain these components will result in potential slips or getting stuck during your working day.

Track chains and shoes

The track chain and the track shoe form the loop, which allows the machine to grip the earth. The track shoe spreads the weight of the machine, allowing it to “bite” into the soil,  selecting a grouser style with larger cleats if the terrain consists of mud.

Track shoes wear unevenly, so it is important that you get it flipped and changed for optimal life expectancy. These components will typically last 1,000 to 3,000 hours under harsh conditions when replaced using optimal spare parts.

Rollers: bottom and carrier

Bottom rollers can help you with a majority of the weight support beneath the track. When it comes to carrier rollers, it will help you with complete guidance for the track chain and reduce tension. 

So, make sure that you regularly check for flat spots or seized bearings every week. Operators need to lubricate the fittings to help reduce the impact of friction. Also, be certain to replace the complete set of rollers together for a balanced life as mismatched rollers cause rapid wear.

Idlers and sprockets

Idlers and Sprockets can help with the tension on the track and steer the track chain. Sprockets propel the machine forward by providing power from the drive train to the track chain.

So, you need to properly adjust the track tension by allowing for a maximum of 1 to 2 inches of sag. For this, you need to work on daily inspections as it can help you get closer to any kind of wear or tear to Sprockets while working in rocky or abrasive conditions.

Maintenance tips for longevity

Check the undercarriage at least weekly, specifically the tightness of tracks, the lubrication, and the cleaning of dirt, mud, or other debris that has built up.

Always go easy on the tracks and never exceed half speed while operating over or near any object that might damage them.

Tracks should be researched daily. Remember, undercarriage costs account for approximately 60% of the total ownership cost of the equipment.

Daily checks

Before each use, get down and do a visual inspection. Check for loose bolts, gouges or spins in the track; wipe any mud off your undercarriage to see the wear pattern.

One key area to pay attention to is tension adjustments. Tension adjustments should always be made while cold, as excessive over-tension will cause premature roller failure.

Signs of wear

Signs that your caterpillar equipment is experiencing premature wear are if your chains are rattling around, your sprockets are spinning freely, and your rollers are wobbling. You shouldn't ignore these issues, or they can derail your track.

The sound levels associated with an undercarriage not only indicate a problem with the idler, but you should also have a monthly inspection of the shoe depth on both chain links.

Cost-saving strategies

You can get ​20% off when you buy a full set of undercarriage kits. You can also find after-market CAT undercarriages that are made to match the original CAT parts, but at a fraction of the cost.

Find the right products from industry professionals. Stocking up on components for fleet vehicles can reduce the cost per unit.

Final thoughts

If you want your equipment to run smoothly, it’s essential to know about spare parts for excavators and undercarriage components. Order your caterpillar parts early to avoid any unnecessary surprises. Keeping your equipment running is crucial to your profitability. Concentrate on CAT undercarriages and CAT undercarriage parts for the best results.

FAQs

1. When should I replace my excavator track?
   Depending on the type of soil, you should replace your excavator's undercarriage every 2,000-4,000 hours. If you work in a rocky environment, you should inspect your undercarriage monthly and may need to replace it sooner.

2. Are aftermarket CAT parts of good quality?
   Yes. High-quality aftermarket CAT parts will perform just as well as OEM parts, while also saving you money.

3. What causes rapid track wear?
   Improper tension (too loose or too tight), accumulation of mud, and spinning cause early wear. Cleaning and greasing the track will help to extend the life of your track to double its normal life.

4. Can I mix manufacturers on my undercarriage?
   Do not mix manufacturers. The different parts may wear unevenly. Stick with CAT undercarriage parts for CAT machines.

5. Where can I get CAT parts quickly?
   Cat parts can be found quickly at any reputable dealer that carries cat spares. Having diagrams will help you order the exact parts you need
