Help, my excavator is completely knocked out!

The machine wobbles and precise work with the attachments is no longer possible? Diagnosis: the excavator has knocked out. Many machines have this problem and the causes are often different. On the one hand, a "knocking out" of the machine over time is absolutely natural, on the other hand, this can unfortunately happen much more quickly due to poor care.

WHAT DOES KNOCK OUT MEAN?

In the construction machinery sector, deflection means the increasing "play" between bolts, bushings and machine. This means that the places where the arm is divided or connected are no longer permanently installed. The use of the machine places high forces and friction on the respective areas. This means that the material wears away over time. In order to prevent this process and to minimize the wear and tear of the material, the machine must be constantly "lubricated". "Greasing" means greasing the pins/bushings, which are greased via the grease nipple. If greasing is neglected and the machine often works on pins/bushings that are too dry, friction and the associated wear will increase.

The result: faster and greater wear. It is therefore quite possible that machines with few operating hours (e.g. less than 2000 hours) are completely worn out and there is a lot of "play" between the bolts, bushings and excavator arm. Conversely, with the right care, a machine can work for a very long time without "knocking". However, the knocking out / play cannot be completely avoided.

We offer you complete bolt & bushing sets for different manufacturers, makes, models and types. Either in a complete set (boom, arm, dipper stick) or as sections from different places. Depending on the degree of wear, you can "bust" the respective areas again. You don't always have to equip the entire arm with new bushings and bolts. Most of our kits come complete with bolts, bushings, gaskets and shims.

Alternatively, you can always request the respective bolts or bushings from us as individual parts. You can easily use our drawings for this and tell us which bolts/bushings/spacers/sealing rings you need.

We offer Bolt & Bushing Kits from Takeuchi, Caterpillar, Case, Komatsu, Kubota, Volvo and more! If you haven't found the right set online yet, feel free to contact us. We will find the right set for you and offer it at the best price!

Here are some example sets as a suggestion: Takeuchi TB014, Komatsu PC16R,Kubota KX057-4, Caterpillar 302.5.
