Chaincase oil

Forums

Hi All,

I have a 1960 ES2, I am having a problem with the quantity of primary chaincase oil, Is the screwed plug a level or a drain? if its a drain whats the correct quantity of oil. I cant find mention of it in the manual.

The level/drain plug seems very low hardly wetting the chain, I was going to use ATF unless anyone thinks this is a bad idea?

Thanks Rob

The screwed plug is the level. One way of checking primary chaincase oil level is to add oil a little at a time and kick the engine over (ignition off of course!) and feel the chain through the inspection hole. When a little oil appears on your finger, the level is right. I use tractor universal oil (high-spec 10-30 diesel oil, no additives, used for engines, transmissions and hydraulics and also cheap) in my chaincases, and my tractors. ATF should be fine too.

It is a level, you only need just enough oil in the bottom of the case to touch the bottom of the chain. Then the chain will splash it around as it spins.

I use ATF in the fully enclosed oil bath case on my Royal Enfield and it works very well, would deffinately reccomend it for use in primarry chain guards.
