My name is John Gannon. I have a business in Australia which
specializes in Kerosene Lamps ,Stoves,Heaters, and Refrigeration. We
have a range of spare parts from all over the world plus I
manufacture some of the replacement parts myself in my engineer work
shop and also have a large restoration service I just received two
KYKO FANS made in England to restore, one with aluminium cylinders
and one with an iron cylinders. My question is what sort of
lubrication oil do I used. It came with about half a cup of oil
slough in the botton of the hot cylinder. This is the first time I
have had the opportunity to work on hot air engines, although some
time ago I built A 5hp Steam engine and boiler which I used in 20ft
launch. Check out my website www.oillamps.com.au

Kyko fans should be sparingly lubricated with a 5% mixture of Wynns Friction proofing oil in kerosene. Two or three drops of the mixture is applied to the power piston sides and the displacer rod. The Wynns product provides adequate lubrication for a few days to a week of continuous operation.

The connecting rod and crank shaft bearings need a light weight lubricating oil.
