Has anyone on the list had any first hand experience removing the magnetic plug on the 912 engine that Rotax has said needs to be removed to check for engine wear? Is it really as hard to remove as they say it can be? I’m getting ready to do this and was curious what I’m getting into.

I haven't seen the ones on the  Rotax engines but the ones that I've seen in GA were just like short bolts. you  will probably have to cut some lock wire and pull the plug.  Usually  it is the same plug used to drain the engine oil so have a container ready to  catch the oil.  When you put the plug back in be sure to redo the lock wire  if it was installed.

  

 If you see any silver coloured  shiny stuff (shavings) you may not want to operate the engine until it's been  serviced by a shop.  A little black grit (sludge) may be normal.   

  

 When you do your oil changes  you should also change the oil filter.  Take the old used filter and cut it  open with tin snips if you don't have the proper cutter ( I don't).  Inside  you will find a pleated paper filter medium.  On a clean bench spread the  filter out and look for large silver particles.  This is where you will  probably find metal shavings before the magnetic plug.

Are you talking about the plug on the gearbox?  I  check it every oil change...

Noel,

First it's field coils on the 912 then it's the magnet is on the same plug 

used to drain the oil.  Not even close either time.  Keep trying, though.



For Roger,  I pull the plug on every oil change.  I use an allen socket with 

a wobble extension.  It will loosen with a pop.  The seal is just the face 

of the case against the inner face of the plug.  I don't remember the torque 

for tightening, but I find the safety wiring the biggest chaellenge next to 

keeping the mess down.

I believe it is on the left side just behind the gear box.

I check mine at every oil change and have not had  any trouble getting removing it.

I did say I hadn't seen a 912 before, so that infers I was speaking

generically.  The most common generic design is to have the magnet on the

inside of the drain plug.  That is the lowest part of the sump and gravity

will bring shavings to the plug the magnet keeps them there. Not only that,

you will easily check the magnet every time you change your oil.



I've heard of having a magnet in the base of the oil filter... A great spot

(sarcasm) even if you opened the filter it's doubtful any one would think of

looking in the bottom of the empty can.



You say it's not on the drain plug ... Ok but I'll bet it's close to the

bottom of the sump well below the level of the oil...  I didn't expect to

find Rotax using self sealing mounts for the plugs, like the turbines have

on the chip detectors simply because of cost...  If they were going to go

through that expense they might as well install a chip detector.



I spent most of today dismounting the carbs etc from my 582 just to change

out the impulse line.  The line that was on it was heavy black rubber gas

line (there when the plane was bought) held in place with a worm gear type

hose clamp.  The way the installation was done the engine mount prevents

getting a socket or a screwdriver in to loosen the hose clamp.  To get at it

I had to remove two carbs, the rear carb boot and the hose for the rotary

valve oil. Then and only then I could get a 1/4" box wrench on it. I

replaced that impulse line with clear heavy tube I got from Bob R and used

the correct spring clamp...... Even getting the long pliers in to place the

spring clamp was an exercise one step short of futility.



You say the spot they have the mag plug in is hard to get at to replace the

lock wire.  I believe you.  I've seen some pretty tight spots to do wiring.

The worst spots are always on engines!!



It's been at least two years and probably close to 14 yr. since the mikuni

fuel pump has been serviced. There is no mention of it being serviced in the

log book.  I'll check the local power sport shops for a rebuild kit

tomorrow...no sense in doing half the job.

Roger

  

 I removed mine on a new 912S it was very tight and  released with a sharp crack sound. My friend recently had the driver twist in  the plug and had big problems. I would suggest a new high quality driver to  start with and be careful to keep everything in line when you try.

The plug can be very difficult to remove.

 Check out the site below for "Expanded Instructions & Tips for the Removal of the Magnetic Plug on Rotax 912 & 914 Engines"

 http://www.rotech.ca/whatnew.htm#MAGPLUGREMOVE

 Good Luck,

 Dick

There is an article about this on page 62 of the January ‘007 EAA Sport Pilot.   It is by Rotech Canada Tech Service.  They suggest heating the aluminum and cooling the plug with an aerosol coolant and have a 7 step procedure.

Thanks David, and others, that sounds like good advice. I’ll make sure I’ve got a good tight fit on everything and it’s good and square before attempting this.

There was a great article on this in the January 2007 EAA Sport Pilot magazine.



The short version:

1-Heat up the engine

2-Put the Torx socket in the head and set it with a smart blow from a small or medium hammer. 

3-Use a breaker bar or a rachet handle with an extension

4-If the Torx slips even the slightest bit then stop.

5-Using a cold spray like "Super Cold R134" to flash cool the plug might help.
