Oil Filter kit installation

Stephen Hill · Aug 8, 2015

I am planning on installing the oil filter kit on my 1972 Norton Combat. It comes with a retaining clip and large hose clamp that goes around the oil filter. This hardware looks cheesy and will just trap grunge. I am thinking about relying on a well tightened oil filter to keep it from loosening. Have others ditched the retaining hardware?? Is this a reasonable approach???

Risk management thinking.
If the filter does loosen then oil is dropped in the path of the rear tyre.
Retainer reduces risk. Your choice.

I figure they put that retainer bracket on the filter head for a reason. No one goes to extra cost unless they have to.

It may accumulate grunge, but it is cheap insurance. I used the bracket on my installation.

The 'cost of failure' is high, total loss of oil, all over back tyre...

Vs

The 'cost of prevention' is low, putting up with cheesy looking clips!

But actually, not having the clips looks cheesy to my eye, as it just looks like 'form over function' to me to leave out such important parts.

All only IMHO of course.

I have it fit like othrs have said if filter comes loose then its going to be a bad day.

The thing lives underneath the bike an even when my bike is on the lift at eye level its hard to see it. When it's on the floor you can't see it at all see who cares what it looks like.

I have to disagree with everyone, I think the retaining clip is for racing applications where everything gets safety wired. Left mine off and its been fine, never had a oil filter loosen up ( always the opposite ). If my Harley doesn't vibrate them off, nothing will.

+1 Retaining clip and hose clamp are completely redundant. After you screwed on a new filter hand tight it gets sucked even tighter to the filter mounting in use.

Hi.
Where does the 'suck' come from?

The 'suck' comes from the rubber ring.

Needing, please stop turning every discussion into a breather thread.........

A related question about the oil filter installation. Has anybody used the dimensions provided by Norton for drilling the two mounting holes in the cradle??? I keep hearing about oil filters crowding the swing arm and wonder if I should build in additional clearance.

I have had my oil filter fitted with no retaining ring, etc, for the past 22 years, maybe just lucky that nothing has happened

yes if the oil filter loosened I could go down, suppose I should tighten a couple of conjoined zip ties around it some day

Until recently i had a Ducati which used the same spin filter as the Commando. On the Duc it spun vertically up from below the engine (and was the low point on the underside when installed!!!) and without any clamping ring. 100,000km without issue.
However i do use the clamp on the Commando, just because it is there.

Or you could look at the setup Jim has, an inline automatic transmission filter, it is a much neater setup

Hi Stephen.

I've done my breather: It's my carbys at the moment.

The 'suck' question was to do with the filter being on the oil return line not the oil supply line. The answer talked about rubber seal compression not low internal filter pressure.

My swing arm at full extention i.e. bike on centre stand touched the oil filter so I elongated the mounting holes on the cradle to provide clearance. The filter mount was already onboard when I bought my bike in '81.

Magnefine. That's what I use now. Simpler, neater, lighter, better.

Stephen Hill · Aug 9, 2015

I liked a number of features of the inline Magnefine. It was a couple of years ago but I couldn't find a convenient source on the west coast of Canada and was shocked at the prices being charged. Please let me know if anybody has a source that is convenient and affordable.

I have no idea if this is the right size for you, but Amazon has them for what I would call reasonable...in USD, I think you are in the great white north?

Good luck Stephen.

I like the outside of the Magnefine filter, but I'm wondering about its inside. Is a filter element that is intended for ATF / power steering fluid suitable for engine oil ? I couldn't find any mention of engine oil on their website.
