Installation of the used engine is a complicated process that requires all procedures and technical requirements to be followed strictly.

Engine installation notes shall be given to the responsible mechanic before the start of work.

According to the requirements and conditions listed in our warranty disclaimer, we provide a 6 months-limited warranty for engines bought from Orbi Motors UAB. The warranty is only valid if the engine is mounted according to the requirements listed below.

Each manufacturer specifies the engine replacement procedure and the work to be performed before starting the engine. When installing the engine, it is necessary to follow the requirements and recommendations specified by the manufacturer. We are not liable for damage to the engine due to an error by the engine and improper engine installation.

If you need any help or advice during the engine installation process, please do not hesitate to contact us.

Before starting the engine it is required to insert a manometer in place of the pressure sensor. The engine can be started when the manometer shows around 0,5 bar, otherwise, the engine can be seized after starting it. Before the engine is started, the pressure on the must reach without any exception 0,5 bar, which is done by spinning the starter without starting the engine ( with a disconnected fuel relay ). The whole procedure must be recorded on a video. If the following condition is not fulfilled, the warranty will not be honored. Please make a video during the pumping up of the oil pressure. If there is any technical problem connected to the aforementioned instruction, please contact us and we will explain the whole procedure to you in order to avoid any mistakes.
