Slide the pins into place: Slide the rear lynchpin into place.Lower the boom arm: Lower the boom arm and maneuver the dipper to line up with the new bucket’s lynchpin holes.Maneuver your boom arm to align the excavator’s dipper links above the new bucket’s ears.

Align the new bucket: Reduce your excavator’s throttle speed to its lowest setting.

Detach the bucket: Lift the boom arm up and away from the excavator bucket until it is no longer attached.

Remove the bucket’s lynchpins: Use a screwdriver to remove the lynchpins from your current excavator bucket.

Knowing how to change your excavator bucket quickly will help keep your machinery in excellent condition and boost productivity.įollow these steps to change your excavator bucket: You might need to change buckets quickly on the job, as specific bucket styles are better suited to particular tasks. The bucket style you choose will also impact job efficiency. To prolong your excavator’s life, you must practice preventive maintenance, including changing worn-out buckets with new ones. If you do not replace a worn bucket, you risk exposing and damaging your excavator’s shank. Like any well-used components, excavator buckets wear out over time. The correct bucket and bucket tooth type can reduce downtime, enhance productivity, increase cost efficiency and expedite a project. The bucket and teeth styles you choose will play pivotal roles in project efficiency and vary depending on the nature of the job. This guide will teach you how to change excavator buckets and remove and change excavator bucket teeth to make the most of your earthmoving machinery.Įxcavators and mini excavators are versatile equipment, suiting projects across multiple industries, from construction and mining to maintenance and materials handling. These are probably one of the more difficult dimensions to measure, but the simplest method is to measure from the front edge of one hole, to the front edge of the second hole.Guide to Replacing Excavator Buckets and Teeth December 5, 2022 If you are running a 26,000 - 56,000 lbs excavator, these tend to be fitted with a hydraulic hitch, therefore the pin centres tend to me set at a standard 450mm or 17 7/10 inches, as the hitch travels to fit the bucket. Please note: If your machine does not have a quick hitch fitted, then the pin centres are not always imperative, meaning the tolerances can be quite large due to the bucket link / H-link being able to move to line up with the hole. The final measurement is the pin centres. Sadly there are no obvious increments for the dipper gap, so it is best to work to the nearest millimetre, allowing up to 2mm for wear and tear. The most simple way of measuring the dipper gap is to remove your pin and slot the tape measure through one hole, and press the tip of the tape measure against the boss at the opposite side. If it is tight and hard to fit to your machine, think about adding a millimetre. See how the bucket fits on your machine, if it has a lot of play, deduct a millimetre or two. Please watch of for the wear and tear on your buckets, as a worn boss or a bent hanger can often give you a false reading. Generally the tolerance levels for the dipper gap are quite forgiving, however they are often measure with +/- 2mm. Get it wrong and it could mean that your bucket does not fit, or alternatively fits but has a lot of slack, meaning your bucket rocks from sided to side when the digger is in operation. The dipper gap is probably one of the more important measurements. Quick Tip: Align the 10cm/100mm mark on your tape measure, then subtract 100mm A handy tip is the bucket pins tend to be in 5mm or 1/5-inch intervals, for example 25mm, 30mm, 35mm, 40mm and so on! Either use a pair of Vernier callipers or tape measure to measure the width of the pin body, or use the hole in the side of the bucket, providing neither are worn out too much. This is simply the diameter of the pin that is used to mount the bucket or attachment to your machine.

While tape measures are probably the most common measuring device in anybody’s toolbox, we also suggest that for the most accurate method using either a steel ruler, and/or a pair of Vernier callipers for the pin diameter. You can use a tape measure to accurately measure all the dimensions you need.
