Oil Filter

[Haddock]

Hi just fitted my oil filter for my wet sump 360 r

I have  hand tightened it as usual with the seal lubricated. 

However although it it as tight as it can be by hand  it is not tight to the top Am I missing something? 

Eg should I use a tool to tighten it ?

With the seal lubricated most oil filters torque to a spec of 11-ish Nm which is most likely what you will comfortably achieve by hand tightening.  They always need quite a bit more force to undo come service time.

First time I’ve been unable to hand tighten an oil filter !

ill have a go tomorrow with a tool up to 11 ish Nm

Never had to use a tool to tighten an oil filter ! Maybe a leather workshop glove for a better grip.

Is the first time that it's had a filter or a replacement?

You do not need to fully compress the rubber seal. As tight as you can get it by hand should be fine.

[SM25T]

When you say tight to the top ..... you are not looking for metal to metal contact. The rubber seal is pretty incompressible. Just tighten by hand. I recheck after warming oil through and cooling.

Can you cross thread an oil filter?  I suspect that’s possible if your using an equivalent that’s not that close a match.  What filter are you trying to fit?

[Jonathan Kay]

Can you cross thread an oil filter?

Yes.

Hi all

Thanks very much for all input 

It’s the PH2874 filter.  Same manufacturer as original fitment  

First time change so replacement 

It goes on easily ( which suggests not cross threaded ) and tighten’s normally. 

When it is hand tight I can see the seal isn’t at the top  

Like many of us I’ve changed oil before so am puzzled.

When you put the two filters side by side do they look identical... length of thread, axial distance from tip of thread to where it seals, type of seal?

Any hint of thread damage?

What happens when you refit the original filter?

Will check the above and report back.

I have always marked the end of the filter, and noted where the mark is as the filter seal touches the sealing plate. I then tighten the filter 3/4 further. This is pretty tight by hand if you have decent access.

On my Seven, getting access to turn it by hand is a pain, so I have bought one of those tools that grips the top of the filter and allows me to use a 3/8 ratchet to turn it 3/4 of a turn.

A quick update; armed with the helpful advice / experiences here I had another go and it looks tight now. 

Interesting experience for me and just proves that even a simple job that I’ve done loads of times can be puzzling and sharing helps 

Cheers all

Well done, and thanks for the amswer.
