In this case we will try to show you the most common intervals of preventive maintenance steps on Jenbacher gas engines. It is well know that the main Jenbacher engines on the market are: Jenbacher type 3, Jenbacher type 4 and/or Jenbacher type 6. The number of cylinders does not affect to the interval, but this is not the case with the type of gas (natural gas, landfill gas, sewerage gas, coal mine gas, syntgas…). «RS Motor» is able to perform any type of preventive maintenance on Jenbacher gas engines. Usually preventive maintenances are performed on-site, but in case of Overhaul or major Overhaul, this could be carried out both “on-site” or in the workshop of «RS Motor». In this case we are going to explain typical operations that «RS Motor» has to take into account when a Jenbacher engine which runs with natural gas needs PREVENTIVE MAINTENANCE.

For replacement of expendables/consumables like oil filters, the interval should be about 1.000 – 2.000 running hours. Then, the intermediate maintenances occur each 10.000 running hours.
After that, in case of Jenbacher engines type 6, the Overhauls occur at 30K and/or 60K running hours. In this case, renew of pistons, main bearings, cylinder liners… is necessary. These Overhauls can be performed “on-site” or in «RS Motor».

Apart of preventive or scheduled maintenances, sometimes the engine has unexpected failures. When this happens, «RS Motor» goes to the customer’s power plant in order to make some inspections for determining the scope of damage. Then the engine is repair taking into account its history, the running hours, etc. This situation is usually called as CORRECTIVE MAINTENANCE. The key is always to try to shorten the stop time of the power plant due t the fac that each hour the engine is stopped, means a lot of money to the final customer.
