Motor Guard filters

[RalphPWood]

Some very soft paper might have the core collapse without the center tube. I will get a filter ready for the pictures for when my wife gets home.

here you are. Notice all Motor Guard parts are gone and the flat washer is pressed on the bottom. The same as the Australian Jackmaster Classic and a few others. I remove the used paper with long nosed pliers. I prefer the orifice at the inlet. I push the paper down hard against the core seal (washer) and put on the top.

Sometimes for very low pressure such as gravity fuel flow from my diesel tractor fuel tank to the injection pump I will use a soft paper such as Charmin Ultra Strong.

Simple and effective, that flat washer works good.

About 1982 I bought a Peugeot diesel. I stayed over at work and installed a Frantz. It was a pain with the banjo fittings.I didnt want to punch the aluminum oil pan. I returned the oil to the steel valve cover. We headed to town with my wife driving. I told my wife slow this thing down. She said it wont slow down. We were running on motor oil. She got off the highway. With the engine running wide open I killed it by shutting off the air with my jacket. Ran the oil to the valve cover on the wrong side of a baffle. Ive often wondered why I didnt go home and get a 2 port Frantz sandwich adapter. I didnt have a 2port Frantz sandwich adapter at home.

Bypass filters are for additional filtering so this guy would've definitely fit in on here. Not needed anymore as filters are leaps and bounds better now. I'd discontinue them. The media is likely highly compacted fine cloth.

These are Motor Guard compressed air filters.Those are old. The new ones are black. The old ones were designed

Hi all! Recently purchased a 1971 F100 with a souped-up straight 6 300. Been sitting for over 20 years so slowly bring it back. I open the hood and lo and behold there are two filters bolted to inner fender well that I had never seen before. Upon further research it looks like there are motor guard bypass filters. A pair of them.

They are unhooked. Opened one up and pulled out what looked like an ancient roll of toilet paper.

Don't know anything about these at all or what the best application is for them or if they even have a use at this point. All new to me. Just curious for some information.

That color means they are Motor Guard compressed air filters designed to use toilet paper. These are old. The new ones are black.

That coler was all metal the same as the origional lube oil filters. The lube oil filters had no coating had 1/8 inch ports and a restrictor orifice.

The compressed air filters had a powder coating and 1/4 inch pipe ports and no orifice. That color is probably from the 60s or 70s. The lube oil filters had no coating 1/8 inch ports and a restrictor orifice. The new ones are black.

**** Cepec tires sold Motor Guards for off road racing which meant a lot of VW dune buggies. Dune Buggies and Hot VWs tested them and had a large article on them. Frantz was a bad design plus they recommded putting the Frantz upside down on the VW.

That is something I cobbled together about 15 years ago. It has been working well.

I spent too much time making a center tube for the Motor Guard M 30. The Motor Guard doesn't need a center tube. All it needs is a flat washer pressed onto the bottom. I did a couple using a 2 1/2 inch OD by 1 1/4 I D washer. I had to ream them a little so they would press on. If they are loose they will stick to the used roll and be pulled out. Push the paper down hard against the washer and put on the top. Best to put the orifice at the inlet. It will press the paper down harder against the bottom when you start the engine. I didnt invent this. Several filters are the same. Only the Frantz needs a center tube. I make the orifice by running a 1/8 pipe tap into the female end of a 1/4 pipe male to female adapter. Put a allen wrench pipe plug in and drill it 1/16 inch.

Did these early compressed air filters have the metal or plastic cores? Were they metal for a short while?

The early Motor Guards were all metal The plastic parts might have started in Manteca California. The black ones. Some use the plastic parts for motor oil. They will deteriorate eventually in hot motor oil.

I think the plastic parts came with the black filters made in Manteca California.

The origional Motor Guards were all metal. The plastic cores came with the M 30s and M 60s.

You most likely need the center tube in a Motor Guard with 4 1/2" paper, the two halves come together and crushed the core 1/4", most 4 1/2" paper has been gone for almost twenty years, back when you were selling your filter, everyone was using 4 1/2" paper.

They were all metal. The only ones ive seen with plastic cores are the black M 30s and M 60s. They have all kinds of stuff now. If toilet paper isnt your thing the special Motor Guard elements will fit the old filters. They aint cheap.

I would like to put over 60 years of experience in one post.

Some use the stock white seals
They dont melt but might need to be replaced eventually. They might be polypropylene.

The white plastic cores came with the black M 30s and M60s all metal before that.
