KS80 & KS90 maintenance
instructions.
The only maintenance your engine will need is the occasional clean.
The parts that might need cleaning are:
To clean the main axle ballrace bearings: disassemble your engine (follow the assembly instructions backward) until you gain access to the bearings. Rinse them in Methylated spirit or Denatured alcohol. Then either blow dry with compressed air or allow to dry naturally on an absorbent cloth or paper towel. Reassemble your engine as per assembly instructions.
To clean the displacer stem: The quick method is to rotate the flywheel until the displacer stem is at its highest point, and wipe the stem with a cloth. The longer (and more reliable) method is to disassemble your engine (follow the assembly instructions backward) until you gain access to the displacer stem (there is no need to remove it from the displacer). Wipe it with a cloth and reassemble your engine as per assembly instructions.
To clean the piston and cylinder: disassemble your engine (follow the assembly instructions backward) until you have removed the piston from the cylinder. Wipe the piston with a paper towel and clean the inside of the cylinder with a rolled-up sausage of paper towel. Make sure there are no stray fibres either on the piston or in the cylinder and reassemble your engine as per assembly instructions.
