Maintenance Of Spark Plugs. Overview; Operations Simultaneous With Spark Plug Replacement - Kohler SFGLD480 Operation & Maintenance Manual

1. INTRODUCTION
This document establishes the maintenance intervals for the spark plugs fitted into the different KOHLER
engines.
It is worth reminding that spark plug performance, like the behaviour of other components, depends on a
number of factors, including without limitation:
- Engine duty
- Full load running time
- Full rate running time
- Fuel quality
Accordingly, it is hard to specify a rigorous number of hours a spark plug can be in service before needing
replacement.
Average intervals stated below shall by no means commit KOHLER to any liability. They are provided
only as a guide to the servicing needs. According to the operating conditions, requirements, and fuel properties,
user has to define whether replacing the spark plugs is necessary before or after the working times suggested in
this document.

2. OPERATIONS SIMULTANEOUS WITH SPARK PLUG REPLACEMENT

Changing spark plugs will take place at the same time as other operations, namely:
- Boroscoping of cylinders to check for absence of polish, scratch, unusual coloration or deposits on the
components of the combustion chamber (liner, cylinder head, valves, pistons and piston rings).
- Check of cylinder compression.
- Inspection of high voltage wires of the ignition system and replacement if necessary. See IO-G-M-33-003.
- Verification and cleaning of the spark plug extender (for engines with the coil on the rocker arm cover -
ignition system defined for explosive environments).
