Oil filter assembly


Recommended Posts

I am missing the circlip that keeps the washers and spring secure on the filter casing bolt. Moss and Rimmers don't appear to have these available now. I have previously put everything back without the circlip when changing the filter, and the filter element itself keeps everything together once the filter body bolt is tightened.

 

However, I am just sorting out a leak from the filter head and at the same time renewing the filter so it would be better if I could source a circlip from somewhere.

 

Does anyone have a spare circlip or know where I can source one.

 

Many thanks

Rob

I don't think they are anything special, just a case of getting the right size external circlip.

I have a casing C/W the the bolt, spring etc in a drawer,(I now use spin on adaptor) I will now go & look at it, & hopefully select a similar one from my circlip set, & post it to you !.

 

Watch this space.

Hi Rob.

 

I have a couple of the correct size circlips in front of me, Have taken the original off my filter, & used one of these - it fits perfectly.

PM me you address, & I will pop them in the post.

2 ways of getting the circlip into the correct place:

The hard way - compress the spring, while at the same time try to get the circlip into the groove using long screwdrivers etc.

The easy way - clip it on the plain part of the long bolt where you can get to it easily, then use a tube / box spanner etc to push it all the way down till it clicks into the groove (you will have to compress the spring to acheave this)

 

Snag with the easy way is that it may over stretch the circlip, but worth trying first - I sent you two !

Thanks again Bob. Your tips on fitting just confirm that even the simplest job (in theory) is not so easy.

 

I'll buy you a pint one day.

I use the "push it down with a tube" method, using a piece of copper water pipe.

The problem I have though is that in all the fiddling to get the housing with new filter screwed back onto the head assembly, I'm sure that 9 times out of 10 the circlip is pushed back out of the groove and just sits on the smooth part of the bolt!

Job done!

 

A 1/2" x 5" box spanner did the trick. Got the circlip on the plain bolt shaft, pressed down with the box spanner over the bolt, pressed further with a 1/2" ring spanner which was compressing spring at same time and heard that wonderful 'click' as the circlip found it's true home. Screwing the whole assembly back in to the filter head was a lot easier than previous experience without the circlip!

 

Many thanks again. Hope to see you at Malvern.

PS: Only used one circlip i.e. didn't break one.

I still have the original filter assembly on my 4A (tried a spin-on conversion years back but couldn't get it leak free so junked it) but haven't bothered with a circlip in years. I cannot see what purpose it serves other than holding the filter element lower to simplify fitting the assembly back to the filter head as Bob mentions. No problem for me working under the car in an inspection pit.

Stops it all dropping out when you tip the remnants of the oil in the bottom of the housing into the bucket! ;)
