Was Norton the first to add a canister oil filter (British bikes) system ?

I don't know which mfr. had the first Canister type filter on a motorcycle, but Phil Irving designed a great big honking thick cloth filtration elemet into the Vincent lubrication system for the Series B 1946 and on bikes. Then they lent a new twin to Tony Rose and family who ran it 100,000 miles over two years of commuting and holidaying, with sidecar mounted and often loaded . In exchange for the free use Tony kept a diary of the maintenance done and any problems encountered over the period. Monthly installments were published in the MPH and elsewhere under the heading "100,000 Mile Road Test"
The test went well , no major problems were encountered and Vincent adopted the sales statement "the first motorcycle with a 100,000 mile engine" along with "World's Fastest Production Motorcycle, a fact not a Slogan"
Phil Irving often said that the biggest advantage his postwar design had over the prewar was the addition of that filter.
I would love to know how many microns the cloth filter takes out.

Bikes like the early Commandos and Dommies that did not have filters were built to a price and designed to have a short but happy life. Eventually Norton saw the sense in extending the happiness by adding the spin on filter, good plan.

Although simplicity may be the ultimate form of sophistication, this one looks a bit too simple. A natural gas fitting and a couple sawed off galvanized nipples jammed into a casting may make a good, usable gift to the needy, but I kinda understand why it ain't moovin there, jethro.

Well, Pete, my name's Dan and it worked just fine. Nothing's "jammed" anywhere, the nipple's are threaded in and the brass fitting is exactly what one would expect for an oil filter. It's very similar to the one that came on Mk III's, when Norton finally got sophisticated enough to put an oil filter on. And though I'm sure there are nicer, more expensive kits out there, this was an economical but workable alternative before they existed. I'm not really trying to "move" it, just offering it up to anyone "needy" enough.

Sorry Danno, my mistake.

Magnefine sells the 3/8" trans filter for $16 on their website. Cheapest I've found.

100,000 miles pah!!

In 1961 my Vin was owned by Bruce Main Smith and was 10 years old. It had already covered 132,000 miles.

Some of it as a combo, some as a solo, as well as the occasional competition outing at sprints, hill climbs etc.

They were certainly light years ahead of the average machine churned out of the other Brit factories.

If you don't want the weight of the original filter set-up then here is a way to do it.

It is a magnafine inline transmission filter. It has the correct paper element inside with more filter area than a spin on filter and a bypass valve at the correct pressure plus a magnet to collect metallic particles. It is available with a 3/8th hose barb on the ends. I use a large rubber o-ring around the outside to keep it from rubbing. Napa has them available.

Jim, have you ever broken a magnafine filter due to vibration or road rash? Being a plastic housing which is so close to the rear tire (it's even closer on my P11), has got me thinking. Also, what hose are you using?

One of the modifications on my bike is machine work on the timing cover to re-plumb the oil system so the filter is on the pressure side of the pump -between the pump and the oil supply to the crank and head. So anything that was caught by the filter had already passed through the screen in the sump plug and the screen in the oil tank.

Would really be interested in seeing what is involved here.

IMHO re-plumbing the oil system as in putting the filter on the pressure side of the pump is redundant because the oil entering the crank is already as clean as it will get in the oil system. Any (metal)dirt from your engine first gets sucked in the sump screen (coarse filtered oil) then the coarse filtered oil is pumped back through the oil filter (fine filtered oil) into the oil tank. Therefore clean oil will leave the oil tank and will be pumped into the crank and head. Putting the filter between the pump and the oil supply to the crank will not make the oil any cleaner. Also that coarse oil screen in the oil tank doesn't do anything (unless you expect dirt entering from the filler opening).

Warning from Magnefine about defective knockoffs: http://www.magnefine.com/warning.html

the one I got off ebay has no such batch #.
cost of genuine vs. copies might be the clue.
