Mini excavator parts and spares
Undercarriage
Undercarriage components for mini excavators — drive sprockets, idler assemblies, track support rollers and pin bushings.
Undercarriage wear is the most common cause of tracks derailing. If your machine is throwing a track, the idler and sprocket are the first things to check. Every part here states the machine it suits, and we stock spares locally in Tasmania.

Parts fitment, stock and warranty
Straight answers to the questions we get asked most about parts.
Still unsure? Call 0449 531 852How do I know a part fits my machine?
Every listing states the machine or engine it suits. If you are unsure, send us a photo of the part or your machine's serial plate and we will confirm the match before you order.
Which engine does my mini excavator run?
The KOOP KD192F and Laidong KM385 are the engines fitted across the AM10, AM12 and AM16 machines. If you are not sure which engine your machine runs, send us a photo of the serial plate and we will confirm it.
How do I read a rubber track size?
Tracks are sized by three numbers: width in millimetres, pitch and link count. For example 230x72x44 is 230 mm wide, 72 mm pitch, 44 links. All three must match your machine. The size is usually moulded into the inside face of your existing track.
Are parts in stock locally?
We hold stock locally in Derwent Park rather than drop-shipping from overseas, so most parts leave the same week.
Are wear parts covered by warranty?
Wear parts such as teeth, pins, bushings and cutting edges are excluded from warranty by nature, so we keep them stocked and priced to be replaced rather than nursed. Pin diameter must match your machine: AM10, AM12 and AM16 use 25 mm; the AM20 uses 30 mm.
