Hyd oil

[Nodlenor]

How much hyd oil will I lose changing the filter on a bx2380?

Less than a cup plus what is in the filter. The oil does not continue to drain when the filter is off on the BX series.

AS Whitetiger said - you will not loose a lot - HOWEVER......... I would have my new filter READY to go as you spin the old off!!!

Don’t be in too-much of a hurry. Take the time to inspect and clean off the mounting base and to assure that ALL of the old filters’ gasket was removed. (and do not lubricate the new gasket with oil or grease as is often suggested because it will “coke” and GLUE the new gasket to the mounting base. Instead, smear a bit of silicone grease on the new gasket to accomplish what is actually intended…. lubricating the new gasket so it does not deform or slip or tear during installation…. while insuring that when you next remove the filter the gasket will not stick to the mounting base.)

I always just used the oil the filter will be filtering for gasket lubrication when changing oil filters.

Am I missing something? Honest question, as I certainly could be...never had an issue using oil...probably only changed a hundred or less filters though.

The intent of lubing the gasket is to prevent distortion during installation…not to seal the gasket. Silicone grease is specified for the spin on aircraft filters…so that’s what I started using about 30 years ago on all spin on filters and discovered that they all remove so much easier later-on while still accomplishing the original intent. Using oil or grease “sticks” the gasket to the mounting base and makes it difficult to remove the filter as well as sometimes causing the old gasket to remain on the engine, etc….. and causing problems with the new filter if not caught.

True on the purpose. However if your oil is coking ever it is too hot.

I get the importance of upmost reliability with aircraft.

BUT as long as a filter actually seals correctly, what does it matter what is used to lube it, except when taking it off and replacing it?

Land vehicles have less concerns...worst case...they can just park and not fall from the sky. BUT...seems like using oil as the lube on a filter gasket on an airplane would not turn out to be an issue, until the filter was removed maybe...

Again, never ran into an issue removing a filter that I used engine oil to lube the gasket with.

Of course the highest I fly is a far as I bounce off the seat when using the tractor and hit a bump!

I often take the old filter and rub its oily gasket against the new one.

I would never take a chance of transferring dirt from anything to a new filter. Just use a bit of the new oil since it is right there.

 

[Shekkie]

I’m Italian so I just rub it on my forehead before installing.

 

[Nodlenor]

Thanks all. I asked the dealer this question when I bought a filter and he couldn’t answer my question. I don’t think he was the regular parts man. Anyway I knew I could rely on someone here, Thanks again.

Shadetrees have rebuilt engines for years on dirt. i wouldn't, but a tad of dirt isn't killing any machine.

Maybe not an old Johnny Popper, But these new tractors every tiny piece of dirt that can get into the system can do some serious damage.

More forgiving than most think. Fuel? No.

It only takes one speck of grit to stick the oil pressure bypass open, you can then spread butter and jam on that engine because now it's toast.

Playing with dirt at a new oil filter may put that dirt on the output side where it would go directly to the moving parts. Shadetrees are still laying under their vehicles wondering why they have no time to enjoy life like others.
