in -line oil filter

[rockthedog]

hi what are your views on a in-line oil filter kit, screw on cartrige type, has anyone had problems with them,is the oil pump able to cope with this kit, thank you mal.

Hi rockthedog

I have both A10 fitted with such filters in the return line, no problems whatsoever.
you can blow through the filters so the pump should have no difficulty pushing oil through it, others will disagree, most folk will consider cleaning out the sludge trap a job well worth doing ----- ONCE, much easier to change a filter

[BSA_54A10]

A standard recommendation for every BSA owner,
The smallest unit is the British Filter one as fitted to WD B40's & B25's.
Only downside is that it is not spin on so takes a bit of fiddleing around to change.
Spin on filters are usually fitted behind the tool box with the filer protruding into the tool box. Hard to see looks very neat but messy to change the filter.
Gold Star Ron ( is he on this list ) does a really neat one that fits onto the engine plates.
It is specific for Pre unit singles but can be fitted to twins.
Hidy-Hide ? do a tubular one which uses A75 filters ( also BMW ) that is easy to fit, hard to see and can be very clean to change

So there are a lot around.
I have also known owners who fitted diesel fuel filters which seemed to work very well but they do not have a bypass so if the element becomes totally clogged you end up with a sump full of oil.

Fitting a spin on oil filter in the tool box is a piece of cake and there aren't any problems. It lets you use a modern 20W50 like Silkolene Comp 4 or similar and avoids future sludge trap build up.

thank you all for the reply, i will go for it,been told the norton commando spin on filter will do the job,

I've just bought one of these to fit to my bike. A friend fitted one to his A10 and its fits easily underneath the ski slope. I dont like the in tool box ones as I need the toolbox for tools.

To add to the ideas, here are the filters I have made, to suit my plunger/ rigid and swing arm A10's.

Not sure where you are rockthedog, but if you are in the states here's a mob who sell filter kits for A10's.

hi guys, came across this one its a early harley replica, do you think it would be o.k. for my A10? i think it looks good,cheers

hi just joined the forum. Im thinking of fitting a oil filter kit on my A10 also .Is there a reason why its conected to the oil return feed rather than the direct feed to the engine
thanks neil

Hi Neil,
Welcome to the forum!
The filter in the feed (suction) line to the pump would be too restrictive, and eventually result in loss of oil supply, and failure of the engine (which is the last effect a filter should be having!).

thanks for that richard. wish id found the forum earlier. some great info

Where does the Brit Cycle filter system, shown in the link by Brian, actually fit on the A10?

Cheers

It is possible to squeeze the Commando type filter behind the battery in front of the rear mudguard (at least it was on my RGS).  I attach a photo.  The filter mounts on to the back of the rear battery strap and the pipes line up well for the hose.  This means I can fill the toolbox with tools and puncture repair kit.  When I was making up the hoses I found that some of the modern ends have appreciably smaller bores than the old BSA ones did, so I used the BSA ones.

re filter position ,  the feed is unpressurised  i/e  gravity feed , whereas return is twice feed capacity  and pressursed 

[bonny]

Is it ok to mount the norton type filter on its side ?

[chaterlea25]

Hi Bonny,
There should not be a problem mounting the filter in any orientation!!
On cars they are mounted at every concievable angle???
The only thing is that it can be a bit messy when changing the filter
I also would not mount one above the level in the oil tank in such a way that the oil could drain down into
the tank ??
It would not really matter, its just that it would take some time for the filter to fill and the oil start returning to the tank, while you fretted as you look into the tank

Another option for fitting the Norton/2CV type filter  . Minimal oil line length, and blue canister to match.
I was pleased to be able to fit it onto the ski slope. (Holes easily filled in unlikely event of wanting to return to full originality.)
Pleasingly neat I think  . Shame about the paint finish  
Now the previously fitted earlier type WDB40 Vokes filter is freed for use on my B50 where filtering will be useful but not so critical on the mostly roller bearing engine (but also clutch).

To fit an oil filter on the feed (rather than return) would necessitate plumbing it in between the oil pump and the crank (big ends/timing side bush feed), which would require redirection of internal oil ways. This would provide pressure into the filter. I have thought about it and would be quite feasible particularly if the dynamo wasnt fitted as the filter could be plumbed inside that case up front, but quite a bit of work compared to an easy return side solution.

However like the popular opinion here, I have opted to plumb a small car filter on the return side.
Fitting it vertically (as per those toolbox examples shown) allows for removal without spilling the oil from the filter everywhere

Most importantly make sure your oil tank is extremely clean as the return filter doesn't remove existing debris in that.

I do like the vokes filter. I understand these were fitted to the 1954/5 daytona A7SS rigid race bikes.
