Oil Bath Air Filter for a 1500 Engine

gybemaster · Samba Member Joined: July 24, 2008 Posts: 445

Ok, so I've just bought this to fit. However, apparently the bent-up bracket held a small bowden cable. One end clipped on the lever arm; the other end was operated by the cooling thermostat via an extension on one of the flap shafts in the shroud. Does anyone have pictures of what the special elongated shaft looks like so I can see if I have it to get the flap to work correctly? (I don't know what I'm looking for or how this setup to the air filter would look so I'm struggling to understand). I'd like to understand it though so if you could help I'd greatly appreciate it.

Also, should there be a little ball of weight on the end of the lever controlling the flap or is that correct as is?

If you have a cable operated warm air control, then it's the same type of setup as the late 60's 1500 air cleaners. Perhaps you should post a photo of your air cleaner in the Late Model Bug forum and see if anyone there has the cable system intact they could photograph for you.

The shoppings going wel Dave, just bought a set of flaps + thermostat that are being shipped from your side of the pond over to me. The one I bought is:

I'm just trying to figure out how I get it to work with my shroud. Any ideas if its possible?

Yes, it is possible. That air filter flap works off of the cooling flaps in the fan shroud that you are going to install.
Off the top of my head I don't have an illustration for you nor do I know if the flaps are different for engines with the cable controlled air filters vs the thermostat / vacuum controlled air filter flaps.

Do a little research on here, I do believe this was very recently covered with someone looking for the cable and the linkage for an air filter similar to yours. The cable system was installed for several years. being replaced by a thermostat on the filter and then a vacuum valve on the air filter. My 69 Ghia has the cable control flap but currently the engine is not easily accessed.

Anyone with information about the operating linkage and IF the flaps are unique for the cable controlled preheat flap??

BTW, with this air filter you would want the newer Breast plate with the 3 large holes.

Cheers Dave, yeah I was going to acquire some tin with the thre large holes. Just need to know now if I can get this air filter fully functioning so hopefully someone can shed some light on how I go about it.

Pending the failure to implement a cable system could I just maually open and close the flap or would that pose issues?

Yes, you can open and close manually. Many people do so depending upon the needs of the season.
What the flap does is decide if you are sucking cold air through the snout of the filter or if you are sucking warm air from the Right Cylinder Head area.

What you may lose is some cold warming up driveability for initial driving off.

There is an argument that fuel being fed warm air vaporizes more completely thus burning more completely, but we won't go there!

So roughly speaking I should have the flap closed at what temp and open at what temp? Just so I can gauge the days as to when I shoud be opening or closing it? (Its not going to cause me engine problems is it not having it functioning with the exact engine temps controlled by the thermostat is it?

djkeev · Posted: Fri Mar 18, 2011 5:10 pm Post subject:

On the air cleaners with the flap controlled by a thermostat (1971) the thermostat opens the flap at 27.5 - 32.5 C (81.5 - 90.5 F).

The thermostat senses the air temperature on the intake snout, not the temperature of the air passing through the snout.

Hope that helps steer you somewhat.

I live in New Jersey where we have cold winters (especially this year!) and hot summers. I (because my vacuum valve is bad on my 72 air cleaner) directly piped vacuum to the operating diaphragm all winter long. I'll undo it one the days are warm consistently, probably late May, early June.

(too bad you didn't know about the cable control needs of the air cleaner before ordering the flaps!)

So in the winter I could leave the flap closed and in the summer leave it open essentially?

djkeev · Posted: Fri Mar 18, 2011 5:26 pm Post subject:

Yes, that's what I've done this year. I've had no issues, car ran great.

I do have the new vacuum valve, just need to get done with other projects and put it in! Should take all of maybe 15 minutes!

I hope I am not hijacking this thread....but I have a question about my oil bath filter too.

I have a 1600 single port engine in my 57'....is the engine to big for this type of filter?

I have heard from people it is not good for the engine to have a oil bath on it.....and I have another friend who says it is fine.

Advice?

Thanks in advance!

If you are not drag racing your 1600, it should be just fine. You might just need to change carb jets to have it work well.

Yes.

Plus as you drive, the paper just keeps getting clogged up more and more.

With oil the filter element of coconut fiber just keeps being cleaned by the oil, and as long as you change out the filter oil when it is dirty as needed.

Think it is a post-1968 air cleaner so the later 1600/1300 engines could be dealer installed in pre-1967 Beetles.
