Maintenance

Monday 30th December 2019 – First 25 hour oil & filter change and check.

With the wet weather prevailing and Maypole closed due to a very wet runway it’s a great time to do some maintenance. With 24.4 hours on the hobbs I thought I’d do the initial 25 hour oil and filter change and a general inspection of the engine.

After this the next thing to do before she flies again is to carry out SB-912-073 which is to replace the carburettor needle circlips. I’ll do that in a couple of days after researching the method.

A quick run up of the engine to warm the oil, remove the cowling, burp the engine, remove the drain plug from the oil tank and drain off the oil.
The oil filter is very tight so is unscrewed using a oil filter strap. The new filter’s oil seal is lubricated and the screwed back on and then tightened 3/4 of a turn by hand.
Probably not totally necessary but I have used a jubilee clip to allow wire locking of the filter to stop is coming undone in servce.
A check of the magnetic plug is required to see if there’s any large bits of engine sticking to it…
I’m pleased to see nothing untoward so it can be cleaned and reinserted.
The filter, magnetic plug and the oil tank drain plug are wire locked to stop them loosening during operation.
The tank is refilled with 3 litres of oil. The oil filter is primed by rotating the prop several times before the first start. Then the oil can be checked and topped up as required.
Then a good check of the engine installation is performed to make sure that all is ok. As you can see by the pictures it’s all is in good order with not leaks evident and still sparkling clean! (for now)
