MB GPW dry air filter conversion?

[918jeeper]

You got me convinced. I'm converting to paper.

I found that STP SA 9053 works well and only requires 1 ring as a spacer on the bottom. The open end has the gasket built into it. The filter fits Chrysler 4 cyl and should be readily available.

I've been using a early 80's Nissan/Datsun Diesel pickup dry Air filter element in my GPW since the mid 80's. I''l take some pics of it and update this post larter today. It ends up being a larger element than the Chrysler elements but does require some minor parts fabrication to make it adapt into the housing.

80's Nissan/Datsun Diesel pickup dry Air filter element

That sounds like the one I use.
I had to cut a donut out of a piece of sheet metal for the top of the filter.
Then I use the original centre bolt.
I also leave the oil pan off the bottom most of the time for better air flow.

Hi guys
I've been watching this thread and am interested in going this way but was wondering which filter element to use.

It would seem the Nissan Filter would be easily obtainable here in the UK. I understand there are a few minor mods. to make it work - I would appreciate any details for these.

Here in the UK there is a conversion to fit a Weber Carburettor to the 2.2litre Land Rover - and I have fitted this to my GPW. Apart from the fact it was new and the cost was very reasonable (£75), I figured as it was a modern carb. it should work better than the original Carter.With the addition of a short piece of tube it marries up to the original horn and air filter system
Indeed, there are a few others here in the SW of the country already running them, and all experience better gas mileage, starting, etc.

I also upgraded the system to 12 volts, and have fitted an alternator - again one from the LR. I have had to fabricate a bracket and have a pulley machined to take the original fan belt. Of course this does away with the need for a regulator box - which I will leave it in position, but not use it.
I have altready fitted an Overdrive to the W.O.F. transmission which incorporates the later drum hand-brake(Parking brake) and the larger centre bearing. Other modifications are to the ignition system. We have found that the Land Rover Lucas # 25D distributor is a perfect fit into the Jeep block with an extention piece to drive it, attached to the shaft. The advantages of this are it comes with electronic breakerless ignition and a vacuum advance/retard mechanism, and the classic car suppliers offer them at a very cheap price (£30)
I believe they also fit some versions of the MGB.
So it would seem logical to go the dry filter route; with Gas costing £1.40 per litre, whatever can be done to make our vehicles more economical has to be considered worthwhile.
I look forward to reading some of your suggestions.

The Nissan diesel filter may be easier to find in areas like Europe or Asia where diesel passenger vehicles and light trucks are very common.

The part you need to fabricate to use the Nissan filter is a sheet metal or thin plastic disc for the top of the air cleaner housing for the new filter to seat against. IIRC, it needs to be about 5-1/4" OD, and about 2.5" ID. Measure the inside diameter of your housing, and use that as the OD, then the ID of the filter element, and use that as the ID of the disc. Should take about 10 minutes to make one. The other parts are the hold down bolt. I use 1/4-20 threaded rod, about 9" long, IIRC, with a washer and matching nut. Jeff says the original filter element bolt can be used, but I did not want to disassemble the oil bath element on mine. I have pics of my setup that I took last Saturday,Edit: Here they are! :

Here's my air cleaner: Oakes with welded on tag


Here's the Nissan element with the base adapter ring made from 1/8" plexiglas, thin sheet metal will work too. The brown stain is from grease I used to seal the metal filter base to the adapter ring.


Here's the 1/4"-20tpi threaded rod stud and the adapter ring seated in the housing


Here's how the element fits in the housing, yes, it's time for a new element! The Wix brand filters have wire mesh reinforcement around the outer element. Not sure about the Fram elements. This one is a "Beck Arnley" brand filter and was installed by me in the mid 80's!


I need to remove the rust that has started to form in the housing and either paint it or clear coat it, since there is no oil in the housing, it and it is bare steel, it can rust rather easily!

Hello
I'll check out my local parts supplier and see if he can help me with the Nissan Filter.
Also it may be practical to have the sealing ring laser cut either from steel or plastic.

Are those Grade 8 Bolts on the Cylinder head? and why the washers?

[JeeperFIN]

I used Citroen Saxo 1.1 - 1.6 (not 16V) filter, Only modification is to put a 15mm rubber disc to the bottom cup of the MB filter.

Part numbers: WA6485 or CA5329 or AG1061
Same filter is in some Peugeots.

Got all of the componants in and am looking forward to making the dry air filter conversion. Thanks, all!

Hi Folks
http://www.richardmilitaryparts.com.au/FGPW.html

look att the picture it is a urethane/plastic spacer 2 stk.and 1large O-ring
,I have one kit inn my air cleaner 5.min innstall
the engine gets better air flow/breathing and a bit more throttle/accelration response is also a bit better
I have a WW2 carburator fitted on my engine
no more messy oil change for me

Hi,
I would not buy the one off Richard as it is $95 US for the conversion and he does not sell replacment filters.
I just don't get it.
Cheers

hello all, I am new at this forum/ message board business, however, this thread attracted my attention.
I helped design a conversion that uses an oiled foam element, which is better than paper and is fully reusable.
If you want a copy of the article I wrote for Jeep Action Magazine, here in Australia, shoot me an email.
I assume that comes off the post?
cheers to all MITCH
