Cures* flickering oil lights at idle if you don't filter the oil.richardthestag wrote: ↑Tue Jun 02, 2020 12:55 pm
On the Triumph oil filter that bottom retaining washer has some form of non return valve built into it, same as TR7 and Dolly. My current stag had it missing when I bought it 26 years ago. Yay unfiltered oil. Seems to be quite a common issue I guess.

Yeah there is a spring and a sealing washer on the bottom. So if the filter is filthy, it can bypass around it. On the ADO16 they include a sensing circuit if the pressure in the filter gets too high to light up a light in the car. Idea being if the filter is providing too high a pressure differential, it warns you that a filter change is needed immediately.

I didn't know that. So variable service intervals are nothing new either then.

Yeah 6000 mile oil change intervals on these modern cars is so reckless!

Better than the 1,000mile oil change intervals on bikes of that time. But then they didn't have any proper oil filters & needed an engine strip every 30,000mile or so to clean the centrifugal sludge trap inside the crankshaft.

Yup, it's one of the jobs I'll be doing on mine once it comes apart. Have a youtube vid showing reasonably clean one.Eddie Honda wrote: ↑Tue Jun 02, 2020 2:42 pmAre you sure? Most traps I've seen are inside the crankcase.

On my BSAs there is a plug screwed into one of the flywheel circumferences, peened in place.Eddie Honda wrote: ↑Tue Jun 02, 2020 2:42 pmAre you sure? Most traps I've seen are inside the crankcase.
Unscrew it (impact driver job) and then use drill bits to get the compacted crud out.
BSA's flywheels are usually part of the crankshaft,
sometimes they can become an integral part of the crankcase
but when that happens oil filtering in not a priority any more.
Triumph, Norton, Enfield and Moto Guzzi have variations on the crankshaft sludge trap I have experienced.
Some later bikes had a centrifugal oil filter system, for example the SS50 had such a thing in the middle of its clutch.
