CARRIER ROLLER 1885612 - Caterpillar

There is a strong electrical shock hazard when the crankshaft is rotating.Do not touch the wires that are associated with the ignition system when the engine is cranking or when the engine is running.
Maintenance of the spark plugs is required in order to achieve the following benefits:
Normal fuel consumption
Normal level of emissions
Maximum service life of the spark plugsThe service life of the spark plugs is affected by fouling due to deposits from the oil and by peak voltage. Maintenance of the ignition system is also affected by voltage. Higher voltage is required by higher inlet manifold air pressure and a higher compression ratio. Higher voltage reduces the service life of components such as spark plugs, wires, and transformers.Removing the Spark Plug
Altronic Ignition System
Note: The Altronic ignition system has a transformer which is mounted separately from the spark plug.
