How to Measure a Loader Bucket with Loader Bucket Diagram
Even the hardest-working, toughest, expertly-operated wheel loader is only as good as the bucket sitting at the end of its boom. If the bucket isn’t up to the job, the machine will be forced to work overtime to keep up and because the bucket faces the brunt of material handling, no bucket will last forever. If you’re searching for a replacement bucket, looking to upgrade your current bucket, or in need of a second bucket to expand your opportunities, the good news is that often there’s a great bucket waiting to connect with your machine.
We’ve already put together a short Loader Bucket Buying Guide with tips and what to consider, but you might be wondering exactly how to ensure the bucket will fit and work with your machine. To help, we’ve assembled this short guide on what to measure on a bucket to make sure it will work with your machine.
Matching the Bucket to Your Loader
Whether you’re searching around the country or around the corner, most people start by searching online using the model, make, and serial number of their machine. Since a bucket designed for a particular machine or salvaged from a matching machine will very likely be a match, using those basic details will help you find early and fast results.
If you’ve been around construction equipment long enough, you already know that often parts will work across machines and with buckets it’s no different. Since you’re reading an article about bucket measurements, you’ve probably already guessed what you’ll want to do to expand your search – grab some fast and simple measurements.
With a tape and a few minutes with your current bucket, you’ll have the measurements you need to connect with a loader bucket seller and open up more inventory and options.
What Measurements Do I Need to Search for a Used Loader Bucket?
To get the measurements you’ll need to search for a new loader bucket, you’ll just need to grab your tape and take some quick measurements with your current bucket. The most important measurements will be in areas where the bucket connects to the machine, but included are also measurements to help you determine the capacity of your current bucket and compare that to available loader buckets for sale.
