Oil bath air filter dismantling

[RichardJ]

Evening all
While procrastinating on some other jobs I thought I’d give the air filter a clean and repaint (s3 1977 swb petrol). But it won’t dismantle more than top from bottom. Any hints on breaking it down more? Removed the top nut thinking the lid would lift off but that didn’t help. No component pics on the interweb (just top and bottom) that I could find ... just discussion of black v silver.
Tried some “gentle” taps on the exposed bolt top centre with no joy. More aggression needed perhaps?

The outer lid, including the vents does come off (probably stuck with paint - remove nut, put a screwdriver in a slot and tap it upwards with a light hammer. And don't lose the little spacer on the bolt), but that is it.

The rest is held together by the rolled over edge where it joins on the oil sump. As you probably already know, the gauze element in this just lifts out.

As John mentions the top should lever off, photo below shows the three parts when I was painting one some years back.

Interested to hear about the silver/black discussion. My military IIa and Dormobile have silver hammer finish filter housings the rest are black.

Also interested in the spacer John mentions. I guess it probably stops the lid collapsing in when you tighten the wing nut (like most filters I've found) but I've never found one fitted. I'll have a look in the parts book......

There is a thin cork strip (gasket) fitted either side of the filter where it's clamped between the middle & bottom sections.

I said be careful not to lose it! It has been present in all the ones I've pulled apart, but it would be really easy to lose.

Ive never seen a silver one, My Series3 is a British Military version and has a black air cleaner. never been painted. All my previous Series vehicles also had black. Obviously since it now has an Electric motor the air cleaner is of little use to me.

Looks like previous owners of every one of my Series Land Rovers haven't been so careful. Couldn't find it in the SII/IIa parts manual because it only shows the filter assembly partly 'exploded'.

Found mention on a couple of UK sites.
My Dormobile is UK built but the IIa GS is Australian Army so assembled here. Both filters showed no sign of ever being re-painted and were in hammer finish silver.
I guess the filter was an outsourced item, maybe they changed supplier or for some reason there was a period when the supplier switched to silver ?

I have seen the occasional silver one, but almost all I've seen were black or had obviously been repainted.

Good, and unless I am mistaken the spacer is present. All it is, is a short length of steel tube - be easy enough to make one.

Thanks for the advice ... the top came off fairly easily once I knew to tap it in the right place.
The gauze section was a different story. Didn’t want to budge. Soaked the joint in wd40 for a day and that helped (not sure what that does to cork tho ... oops).
So I managed to get that section off ... and behold, there’s another one underneath. After a few tries to get that off I noticed what could be spot welds, so assume it’s supposed to stay put? Do you have to clean that one? I’m happy to mask around it for painting.
Might need to replace the cork seal though ... have I rooted it with wd40? It looks complete at this stage.
I’ll be doing mine black again ... the colour thread I found was this:

Evening all
After dismantling, sanding and painting my oil bath filter (it looks a treat now!), I've progressed downstream to the carburettor elbow.
My elbow seems to have more protrustions than most ... the ones on the web have a single tube that allows a connection from the elbow to the rocker cover vent cap.
Mine has that ... and more.
149201 149202

The angled one had a golf tee wedged in it, the hole on the elbow body had a bit of electrical tape over it and the thin one poking out the end just seems to disappear up the elbow.
What are all the extra appendages??
Should I just get a new golf tee and more tape?

I have never seen one with more than the one connection for the top rocker cover breather, and pre-mid 1960s with no PCV had none.

I suspect that someone may have replaced a Zenith or Solex with a Stromberg and run the pipe from the filler tube to here as well, which would not give very good crankcase ventilation.

Same theme ... different part.
I removed the air cooler / battery bracket, scrubbed, sanded, rust converter ... taped where the battery earth connects then painted the rest (looks great! ... but will take a lifetime at this rate).
Then engaged the brain. Problem: earths have to go somewhere. Assume I should expose bare metal where it bolts onto the battery tray and starter solenoid? Or earth strap it to something else?
