[keyhole]

I unscrewed the oil filler cap, and decided to remove the filter before draining the oil. in case I had a problem with the filter removal. However, using the special wrench the filter cap unscrewed quite easily.

Now revealed, the old filter element was quite an effort to extract from the filter canister - it need a good vertical pull as the 3 internal O rings grip very firmly.

Once the filter assembly is removed from the canister the old filter can be slid off the shaft in a downwards direction. Four new O rings are supplied with the filter, and three must be fitted in the correct grooves on the shaft and one on the cap. You can ease them off using a small screwdriver, as shown below. This is the large one fitted on the filter cap.
