Posted: Sun May 17, 2009 5:42 pm Post subject: Stuck Oil Filter

Can someone verify if the Rotax 912S oil filter is a standard thread  (clockwise to tighten)?  Getting ready for the first start and can't get  the darn oil filter off to purge the oil system.  It's now clearly into the  "need a new filter" stage as I've bent/punctured/mangled it trying to get it  off.  Tried PB Blast where the filter contacts the engine and it's  just not budging...any ideas...tourch/heat??? 

  

 Thanks,

  

 Chris

left will loosen and right tighten. You may need a set of the oil filter channel lock type pliers that have a set of sharp teeth to get a good grip. It will come off to the left. You need the pliers to grip it around the base metal ring.

Chris,



The thread is standard.  I have always had to use one of the filter wrench 

attachments that fit into a socket wrench type breaker bar - usually after 

tapping it onto the end of the filter.  From what you say, you may be passed 

that point as that tool will only fit on the end of an undamaged filter. 

The rim of the filter is heavy gauge steel and if you can get a pipe wrench 

or channel locks on that without damaging anything, that should work. 

Others might have other ideas.



Regarding purging the oil system.  This is usually done after an oil change 

to purge any air that might have been introduced into the system during the 

oil change especially if the filter is changed or the magnetic plug is 

removed for inspection.  You will want to pressurize the tank per the 

instructions after you remove the damaged filter and replace it with the new 

one.  During the purging process, the only open lines will be where the 

compressed air is introduced - the oil tank, and where the oil will 

eventually drain into a catch basin or bottle - the oil return line to the 

tank.

Thanks Lowell - I'll try the pipe wrench and let you know how it  goes.

Lowell,



According to Rotax-Owner.com you do not need to purge the oil system after you do a simple oil change.  Basically if you work on the suction side of the system, you will need to purge the system.  Yes, the tank is on the suction side but as long as you don't remove the tank and drain the suction line, you don't need to purge it.  I have attached a Technical Article from the site for anyones information.  It does a good job of describing the oils system, the SI's that have been put out by Rotax and examples of when oil purging is required.  Take it for what it is worth but this is what they have to say about purging and oil changes.  I personally have purged my system after each oil change but to be quite honest, I have never had a situation where the lifters had air in the either before or after the oil change.

Speaking of a stuck oil filter,during my last oil change I had something  quite different. I knew they could be a bugger to get off so I fitted my oil  filter removal tool but noticed the filter moved before I even got the tool on !  The filter then spun off in my hand with no effort at all ! That would have been  a mess in flight if it spun itself off ! Quite likely ,would have ruined my  day!

  I tightened it down per the factory instructions when I did the  prior oil change. I had the instructions right in front of me and followed  it to the letter (including the engine run and filter tighten check) I told Dean  at Lockwood about this and he said I was one of two people he had heard of this  happening to.

  Well once is enough so I have installed a large hose clamp around the  filter (lined with rubber-Adel clamp like) and have safety wired the clamp to  the engine so the filter won't move (also torque marked it)

Darin,



I appreciate the heads-up on this.  I have not been aware of the information 

you mention.  My thinking is that when removing the oil filter and the 

magnetic plug, oil will drain and the oil draining out of the engine at 

those points will result in something replacing the volumn of oil lost. 

This - most likely air.  I guess if you are really quick, the air introduced 

will not be problematic.



Also, when I changed the oil, I would use a vacuum drain apparatus that 

would suck the tank dry, I would then open the tank and wipe it out - this 

would be on the suction side.  There was always a lot of silvery sludge 

there after one of the AVGas use periods.  If I were to make a guess here, 

it would be that Rotax found that with the engines that were merely drained 

and refilled, like everything else out there, the no purging idea might be 

good for business, i.e. less complexity.



I suppose with the new build, I will purge just like the old days.



What I was trying to suggest in my original post  was essentially that 

removeing the oil filter is not part of the purging process.



Lowell

Before I ever started my Jabiru, I used structural adhesive to attach  

a 4-leaf clover-type device to the top of the filter like the big  

boys do, and safety wired it. Since then, the filters have been so  

well secured, that I haven't bothered with any kind of securing other  

than to make sure that I give it one turn beyond gasket contact, per  

the Baldwin filter B33 instructions....so far, so good, with around  

20-24 filter changes.

Lowell - I'm happy to report that the pipe wrench suggestion worked like a  charm!  In less than a minute on my way out the door for work this morning  the filter was successfully removed -  a pleasant alternative to the hour  plus spent last night trying to mangle it off...

  

 The reason I was trying to remove it was to follow the instructions in the  HomebuiltHelp video with regards to first start procedures.  The video  advises adding three quarts of oil to the tank then pulling the prop through  numerous rotations while adding oil to oil line marked "out" via a funnel until  oil discharges from the oil filter port (with the filter off) to purge air from  the oil system.
