The Hitachi ZX210 excavator travel gearbox is quite complicated to build. This ensures perfect and even operation of the transmission. But over time it can generate huge costs associated with its repair. /Hitachi travel gearbox repair/

/Hitachi travel gearbox repair/ The HITACHI ZX210 driving reducer most often breaks down for two reasons:

– too much looseness on the gear wheel bearings,

– unscrewing the lock nut of the main bearings.

In the first case, it is enough to replace the individual reduction sets with new ones, or use a new housing. In the second case, howewer, when the bearing lock nut breaks, you will probably need to install the entire new travel reducer. And also install into it the old, original drive engine with a damaged final drive. This solution will allow you to eliminate faults 100%. While maintaining certainty that within a year or two we will not have to repeat the process.

Individual parts can be replaced by a mechanic after consulting the adviser from whom spare parts were purchased. However, if a new gearbox needs to be used and the original engine is shifted, this should be done by a specialized company. Do not open the drive engine without much experience. This can result in duplication of repair costs. Most often, mechanics fold components of the piston pump incorrectly, which causes its damage.

The most important thing is to operate the machine according to the manufacturer’s instructions. We know perfectly well that sometimes this is impossible. Therefore, problems with the machine components are unavoidable. If we want to protect our machine against damage to the running gear, we recommend regular oil change. Or just listening for the engine running. More on this in our other article: How to avoid driving gear failure?
