Thank you for a really good video. Just a couple of thought I picked up from Rotax training at Lockwood. 1) After inspecting the oil tank’s “O” ring for cuts and nicks, be sure to lubricate the “O” ring before reinstallation. 2) To ensure the oil filter fills and any air that may have entered the lines is purged, rotate the propeller (as you described) 30-50 times until a normal oil pressure is achieved. The easiest way is first to ensure the magnetos are off* (shorted to ground), remove one plug from the bottom of each cylinder (noting the cylinder from which each plug was removed) and manually or using the starter, spin the propeller. If the latter, remember to pause after 30 seconds of cranking and allow the starter motor to cool down, then repeat until a normal oil pressure is observed. Re-install the plugs to the cylinders from which they were removed and torque to spec. *Note: It is really important that the magnetos are both grounded. Otherwise when cranking, the engine will attempt to start and without the plug, the high voltage will discharge into the electronic module, damaging it ($$$). If you’re not sure, disconnect the battery and manually turn the propeller. Thanx again. Great video.

Great thorough videos. Few weeks ago I had the thrust washer fail on my 912iS at 1700 hrs. Found lots of plastic debris in the bottom of the oil tank, and some slivers of metal. I've now replaced engine for new one. During take off I had drop in oil pressure followed by spike in oil temp and surging of my hydraulic prop, landed without issue. Probably could have had gear box rebuilt and flush engine but I use for survey work so I opted to replace the engine.

Very well filmed! Loud and clear understandable and correct. One thing- really important with Rotax: you've forgot to check the magnetic plug!! It is of great importance and mandatory. If there are metal parts found, the gearbox has to be inspected. So unscrew the mag plug, visual inspection, clean , rescrew calibrate and finaly secure it with wire.

My Rotax powered aircraft was spitting oil today. Upon inspection, the oil filter was noticeably loose. Wondering if it was improperly installed or vibrated loose over time. Mechanic said the Rotax motor is the only airplane motor he knows of where the oil filter doesn’t lock into place. Dipstick reading in the middle pre- and post-flight.

Great instruction video Jeremy. As there's very little space to catch oil when removing the Mag plug, is there any reason why it can't be removed while the Filter is removed? Thanks James.

Great video. I use Avgas as well, maybe 60%, I installed the Curtis drain valve and had a lot of trouble opening the valve. Luckily I did not apply excessive force or used a tool. Turned out my 2016 Bristell with the ULS has a modified shelf at the bottom of the tank which is curved towards the bottom, preventing the drain valve to come out. So in the future is it OK to just open the clamp a bit before opening the valve?

The anti-drainback valve isn’t the reason you can’t fill the filter before installing it. It is because Rotax mounted it horizontally. On my cars that have a vertical filter, I always fill the filter before installation and all cars have the AD valve. My Chevy truck also has a horizontal filter that can’t be prefilled. It would be nice if Rotax used a cartridge filter like my newer Chevy cars. They are on top of the engine and much cleaner to change and you can inspect them easily with no metal can to remove. I hope Rotax follows the automotive lead and includes that in future designs.
@JM_Aeroservice4 жыл бұрын
The 825-703/706 filters Rotax used for years until 2010 could be prefilled, after adding the anti drain valve to the new 825-012 and 825-016 filters you could no longer get oil into the filter without installing it and manuelly priming it.
@LTVoyager4 жыл бұрын
Jeremy Macgregor I don’t see how this is a function of the AD valve. All cars have had those for years and it is still easy to prefill the filter. You just pour the oil in the hole in the center of the filter. Sure, you can’t fill through the perimeter holes as the AD valve blocks those, but you can still fill the filter through the center hole.
@JM_Aeroservice4 жыл бұрын
I know what your saying but on the Rotax filters you can’t even fill thru the center hole, the most you can get in there is about 1oz if that. Typically on an oil filter you can fill it thru the center and allow the element to get saturated but on the Rotax Oem filters that is not the case, I personally liked the oil style filters.
@LTVoyager4 жыл бұрын
Jeremy Macgregor That is odd. When you cut it open, I didn’t see anything blocking the center hole. Is there another valve there that gets opened when the filter is screwed onto the engine?
@julesviolin2 жыл бұрын
@@LTVoyager what Jeremy means is the filter valve is closed so that stops the air escaping which in turn stops you getting oil into the filter. My simple life hack is to use a syringe and fill the new filter via one of the small holes. Very carefully displacing the rubber valve . That way you can fill the filter to the brim and then quickly fit it to the engine with very minimal oil loss 👍✅
