The hydraulic pump is the heart of your mini excavator's hydraulic circuit. It generates the pressure and flow necessary for all working components: boom, arm and bucket cylinders, swing hydraulic motor, hydraulic distributor, and travel motors. When it wears out, the entire machine loses responsiveness and power. At Codimatra, used hydraulic pumps are dismantled from carefully selected machines and thoroughly tested in our workshop before shipping, allowing you to replace the part without the cost of a new pump.

A worn starter doesn't fail overnight. It gradually deteriorates, with increasingly difficult starts and accumulating electrical symptoms. When temperatures drop, these weaknesses become apparent: the engine oil thickens, the battery provides less power, and the starter must compensate. For Kubota, Yanmar, JCB, or Komatsu mini excavators, Codimatra offers carefully selected and workshop-tested used starters compatible with the main engine types on the market.

During winter, when temperatures drop significantly, construction equipment often faces cold start difficulties early in the morning. Winter is a tough challenge for your machinery: the battery, engine fluids, glow plugs, and fuel system are all affected simultaneously, often without warning signs. On a job site, a machine stuck first thing in the morning can quickly disrupt the entire day’s work schedule, delay tight deadlines, and require unplanned personnel interventions. Understanding the causes of starting issues, identifying vulnerable components, and performing some preventive checks before winter helps maintain machine availability throughout the cold season.

On construction equipment, engine belts drive several critical components: the alternator, water pump, air conditioning compressor, and the fan. Their condition directly impacts the machine's availability on site. Dust, temperature fluctuations, and constant mechanical stress accelerate their wear. Being able to identify early signs of wear allows intervention before failure, preventing costly downtime during operations. For over 40 years, Codimatra has offered tested and inspected used parts for construction machinery from all major brands.

Regular maintenance of your mini excavator is a crucial investment to preserve its performance and value over time. With an average lifespan of up to 8,000 operating hours, these construction machines require a strict maintenance schedule, particularly regarding oil changes. Our guide outlines universal maintenance procedures suitable for all mini excavator brands, helping to optimize their longevity and efficiency on your job sites.
