Some buyers like end users, dealers and distributors might be not professional in excavator buckets. They must have such questions like “How to check the excavator bucket quality?”, “What is the most important for the excavator buckets?”, “Which Bucket Fits My Digger/Excavator?”

If you are unsure of which bucket required to fit your machine, you were often asked to confirm a few dimensions on one of your old or existing buckets! This seems to scare people more than it should, as it is very straight forward to do so, as long as you know where we need you to measure. Below is a brief guide on what measurements required to make sure you receive the correct bucket!

This guide is to show you the most important issue: dimensions, even mounting dimensions. This could let you know whether the buckets will be fit with excavator arm and bucket link!

1. Pin Diameter

The pin diameter is as simple as it sounds. Take one of your old pins out of your bucket, and measure how wide the pin is! The easiest way to do this is with a set of vernier calipers. However it can also be done with a tape measure or ruler! Alternatively, you can measure the inside diameter of the boss on the hanger! Please allow a few millimetre wear if the bucket is well used!

2. Dipper Gap

The dipper gap is the internal measurement between the bucket hangers, or bucket ears as they are sometimes referred to! This is the section where the main arm of the digger fits in, and also the bucket link.

You need to measure the smallest internal size, this is often between the bosses on the bucket!

The easiest way is to measure using a tape measure or ruler. You can also measure the outside width of the bucket link, however these can often be worn, and as a result, give inaccurate measurements, so only use this method if really necessary!

3. Pin Centers

The final measurement we would need to find the bucket you require is the pin centers. This is basically the distance between each of the 2 bucket pins from centre to centre!

The easiest way to measure these is by using a ruler or tape measure! Tip: Instead of guessing where the centre of the pins are, measure from the front edge of one pin to the front edge of the second pin!
