Hi All,
I wanted to fit an external filter to the SR on the bench, I had fitted some previously into the tool box
The bikes owner was anxious to retain the space in the toolbox (has he no faith in me ????)
so I came up with the position in the photos.
I sandwiched a piece of 3mm thick SS plate between the frame and the toolbox using the tool box mounting studs
and mounted the filter head to this!
Cheers

That's neat John

And here is how I fitted a filter to my bike. It uses the standard BSA Rocket 3/Triumph Trident filter cartridge.

This topic looks like the appropriate place to post this.
A couple of years ago I bought an oil filter adaptor online from J&P Cycles, a large parts seller for all kinds of motorcycles, but not really vintage British. Vintage Harley, yes. Anyway, when it arrived, I thought it was much too large and there was no way I could or would fit it to the bike.
Now, on the verge of completing engine repairs, I wanted to run with a filter right from the start. Back when I bought the large adaptor, J&P was very gracious about taking it back for total credit, but now, a restocking charge and more shipping cost. I'm feeling cheap right now, so I decided to take another look. The photos show what I came up with. If I decide I don't like it, it will be easy enough to remove, leaving no trace. It is held in place with a bespoke bracket under one cylinder base nut (for now).
Oh, the install needs to be cleaned up and, no, I'm not going to try to run without a feed pipe.

hi all,
i like the idea of an external oil filter with these modern oils,any idea who sells the kits/parts in the uk,although i dont want to fit it in the tool box.
cheers rob

Hmmm, this is turning into a "you show me yours and I'll show you mine" thing.
Here's mine, I used a Rocket 3 type like John has but mines under the ski slope.
I also fitted a DVR2 under the seat and removed the mounting brackets in the toolbox that hold the original regulater, gives me quite a lot of room in the toolbox.
The second pic is how I mounted the filter to my "bitsa" plunger A10, same filter but I wasnt concerned about hiding that one.

Filter in the tool box for me. IMHO external filters spoil the look of the bike, sorry chaps.
Once you get shot of the old relay type voltage regulator from the tool box and replace it with a small modern one you have oodles of room in the tool box. I carry loads of tools in mine even though I also have a fuse box in there as well. I've only needed the tools once though in 4 years and that was to tighten up a mirror.

I agree with Alan (but also admire the external filter arrangements shown in this post).

I would much rather keep it hidden (as the actress said to the bishop)

Hi Richard, wondering what size those connectors are in pic 2, I'm rewiring the RGF (which was done in a rush) and want smaller connectors than the standard ones (6mm I think the standard ones are).
Yes I also like the metal piped in filters - neater- but think it would be better still with slightly smaller bore pipe if it can be had

Hi Bill,
The fittings are Swagelock (stainless steel). 1/4"BSPT - 8mm tube 90 degree adaptors. I can dig up the part no if you need it. They aren't cheap. You could do it more cheaply with brass versions (which Swagelock also offer). I like / enjoy the quality of the SS Swagelock product.
The tubing is 8mm OD (approx 6mm ID) stainless steel. I wouldn't consider going to smaller (OD) tubing.
Note that Swagelock 8mm tubing bulkhead fittings are mounted in the rear wall of the toolbox. The 1/4" BSP female swivel fitting on the standard A10 oil hose(s) screw straight on the bulkhead, so I just re-machine the internal seat to a 45 degree taper and yippee; no leakee!
I use the standard oil hose set, PLUS an additional one which is shortened, then added to the one returning oil from the engine, into the toolbox filter. To join the two bits of this hose, just machine up a 5/16"double barbed joiner. You can also source off - the - shelf brass ones from the likes of Ryco, or Enzed.
You could then tighten a worm drive clamp over each side; I machine up compact shells out of aluminium, and crimp one over each half of the barb.
One of the two standard hoses is used from the filter, back to the oil tank.

Cheers Richard - copied and saved

I have to admit ..the way You have managed to fit those filters out of sight like that is brilliant !
Wish I had a fraction of the talent of some of the members of this forum .

As I recall, Richard (Orabanda) fabricated his own filter adaptors. Very nice, indeed. The internal approach is notably better looking, but I spent about 1-1/2 hours (not including trips to the store) on the install and no .room is taken up in the tool box. On the othe hand, the bike is yet to run on this build.

I bought a Norton 850 oil filter head and filter from Ebay intending to fit it in the toolbox of my plunger frame GF as others have done. However, the assembly was too wide to fit in the toolbox so I have mounted the filter on the rear mudguard behind the gearbox using nylock nuts.
Both parts are dull black so fairly inconspicious.
When mounted the filter head union stubs point towards the chain.
I've used Goodyear 8mm/5/16" ID reinforced rubber pipe to do the plumbing.
The oil feed pipe from oil tank to pump union pipes is as original.
The return from the pump is carried over the top of the gearbox, down between the vertical frame tube and the gearbox then gently curves around to meet the filter inlet stub.
The filter outlet pipe is routed tightly underneath the gearbox and then up behind the pump union assembly so it appears adjacent to the original metal pipes. It lines up nicely with the rocker feed banjo and oil tank connector.
Finished off with proper hose clamps it looks neat and not too obtrusive.
Here is a link to some photos of the set up.

Are these inline filters a big help preventing engine wear ?
I change the oil every 1000 miles at the moment , would this still be necessary with the filter in place ?
I doubt I would have the skill to fit one unfortunately .
-
G'day Steve. I'm sure you'd be up to doing it, your bikes didn't build themselves.
The filter is a definite for use with multi grade oils. Most important is to clean out the oil tank thoroughly as the filter is on the return, any crap in there will go through the motor before being filtered.

Jim ,
Welding (especially Aluminium or Stainless Steel) , no problem ..anything mechanical I have to leave to My friend Steve Hughes or My Brother Michael .
It usually works itself out one way or the other !

Are these inline filters a big help preventing engine wear ?
"Very probably" is the best answer I can think of. They should stop ferrous debris of a particle size that might wear the pistons and oil pump and take up space in the sludge trap. Also bits of gasket and sealant that could maybe end up restricting an oilway.
I change the oil every 1000 miles at the moment , would this still be necessary with the filter in place
In what way is it necessary now? A filter makes no difference to oil degradation by heat, and little difference to amount of suspended lamp black.

Stephen,
If you have a couple of old armored hoses to scavenge, the plumbing is pretty easy. The only "skill" I may have used was beating the crap out of strap of metal to make a bracket. If you're looking for an Orabanda-grade install, THAT is another matter.

I bought my kit off Goffy. Sits in the tool box and runs on 2CV filters. All the fittings came with. I think I just drilled a hole or two in the back of the tool box was all. I do miss the space it takes up though. As noted elsewhere I run a 'modern' detergent monograde to carry the bits through, and change every thousand miles anyway.

Hi all, attached is a pic showing the oil filter on my RGS, which fits out of sight between the rear of the battery and the rear mudguard. It's a fairly close fit but the oil lines connect really easily. The filter base is one of those Commando things and it's bolted on to the back of the rear battery strap.

Gold Star Ron does a really nice kit as seen on this page http://goldstarron.com/tips/tips1.htm (http://goldstarron.com/tips/tips1.htm).
However he is not particularly well at this time having been doing battle with various cancers and by products of the treatments for the last couple of years.
However you could give him a buzz if you like his kit.
Fits all pre-unit swing arm BSA's.
Neat, clean, easy to fit and even easier to service without covering you & every thing else with oil.
Even better I am fairly sure that it takes the short Briggs & Stratton oil filter which is cheap & readily available.
