Excavator

An excavator is a large purchase for most companies, so it is important that after general wear and tear, the spare parts you are likely to need are easily available and affordable.

It is little use getting a great deal on an obscure machine, if getting hold of the excavator spare parts is a problem, both time wise and economically.

The most common excavator spare parts that you are likely to need are:

Undercarriage components, in particular sprockets and bottom rollers. As a general rule you should replace sprockets whenever new tracks are put on the vehicle. This is especially true for rubber tracks that wear down the dwell between the teeth towards the sprocket centre, rather than wearing down the actual teeth.

Replacing the sprockets at the same time as fitting new tracks will ensure that they will mesh properly and that they are of the correct pitch.

Bottom rollers should be replaced either one track frame at a time, or as a whole lot. If you fit a worn roller with worn components, the new item will be bearing too much load. This could cause premature failure.

Tipping Links and Bucket Links - One way that damage to tipping and bucket links can occur is from the action of bucket pins coming apart during digging. Damaged or broken links should be replaced immediately. If not, then damage could occur to the dipper arm, bucket ram and bucket. Tipping links and bucket links are often sold in pairs.

Bushes, Pins and Seals - These can usually be ordered and purchases separately or as a kit for a particular machine. Check with the stockist that sold you your excavator.

Teeth, also known as bolt-on-teeth - for penetration of soft or hard ground, strong and sharp teeth are essential. These will mean that the excavator can dig with less effort and thus increase efficiency.

If the teeth are not sharp then the percussive shock that is transmitted to the digging arm is greatly increased. This has a knock on effect to undercarriage and slew arm. One result of this is that the excavator needs to use more fuel to move each cubic meter of soil.

When you are purchasing replacement teeth, make sure that you know if the price you are quoted includes all the necessary nuts and bolts to fit the them.

If you don't wish to burn off all the old nuts and bolts, there are replacement teeth that bolt onto an adapter that needs to be welded onto the cutting edge once only.

This has the advantage of being able to replace and swap tips easily and quickly. Types of these replacement teeth include, a single leg bolt or weld on tooth, a 2 leg, bolt on side cutter, sold in pairs.

As well as the above, you need to consider your general excavator spare parts, and how often they will need to be replaced.
