NAPA part numbers for WMO filter set up. - Steel Soldiers::Military Vehicles Supersite

Kaiserjeeps · 12-18-2011, 15:46

Edit, Please see page 5 for researched part numbers for bases and filters to get you started if spin on's are for you..

Edit: these are for a spin on filter set up.
After borrowing some books from the local NAPA I found this info.
Please post your part numbers if you make something and post up.

With costs in mind everything is based on a 4034 base with a 1X12 filter thread. The base is 21 bucks and all others start at about 50 bucks.
The 4034 is an inline mount with no mounting flange. All the others have mounting flanges and cost more.

The first stage will be a 5 GPM racor water removing funnel. Thanks Hammer.
The first filter will be a 4034 base.
Filter is an 1158. 30 micron 6.9 high and bypass set at 18-20 PSI
There are others but they are smaller.

Second stage is a 4034 base and filter choices of... All below are 1x12 threads and #1747 is the biggest.
#1754 16 micron 7.3 inches high, 12-16 GPM
or# 1747 10 micron about 8 inches high, 12 -16 GPM #1789 is a 23 micron
#1462 23 micron 6.9 high 12-16 GPM

I was unable to find a 5 micron or better in a 1 X 12 thread. Do you know of one?
Third stage requires a hydraulic base # 4746 at about 50 bucks. 3/4 inlet and outlet with a 1.5 X 16 filter thread.

Multiple options, These are all 1.5 X 16 threads and the most expensive filters out there. The base is also pricey. See page 5.
#1847 is first choice at 5 micron 11.2 high 40 GPM
# 1847 7 micron 11.2 high at 40 GPM
#1746 5 micron 6.8 high 40 GPM
#1556 6 micron 6.8 high 40 GPM
# 7200 3 micron 6.6 high 40 GPM? I am suspecting this is not right.

There is a fueling water trap filter # 725-8201 base and cartridge 10 micron
refill filter is #725-8202
This has potential.

I am reading hydraulic oil has water in suspension. I have a lot of oil from an old backhoe. Do I need more water removal than the racor filter will provide? YES, you need to heat it and let it sit. Drain off the water later that has precipitated out. A day or three.

I also just found a source for a LOT of WMO. Looks like I am getting on the WMo band wagon.

Hope this helps.

I was using 86281 and 86418. Both are WIX numbers and should cross over. In front of those was a house filter using a 20 micron filter. I was using a WIX mount for each ... I don't recall the part number or thread size ... I'll have to look it up.

But I switched out of spin-ons ... I found that the filter sox were a lot cheaper and easier/cleaner to use.

I ended up making a filter bag housing out of a big old fire extinguisher similar to: bag housing | biodiesel supplies

... and I'm using 3 filter socks down to 5 micron.

I also found that WMO filters a LOT faster and easier if you heat it. I use a 220VAC water heater element ... and power it with 110 VAC. Get the element from Home Depot for about $14.00.

I've been heating the oil to just over 100F before pumping.

The only good method I've found for water separation is heat and time. I heat the oil in 20 gallon batches ... I let it heat for a couple hours ... then I let the drum sit for about 5 days ...

I wouldn't mess around with spin on filters and look to racor filters. I use 2micron

M35A2-AZ · 12-18-2011, 17:35

Here is a 2 micron spin on, Wix 33674 & Napa 3674 Fuel Filter.

Kaiserjeeps · 12-18-2011, 21:43

I just checked the cross over book I borrowed and I could not find the 8 series WIX numbers. The only went as high as 5*****

The wix or Napa 3674 is a 1X14 thread. The base I priced out is 1X12.

How often are people changing the filters (spin on)?

I don't know much about the bag filters. Can you clean them and reuse them or are they a replace as needed? Do they go in a can?

There has to be an optimum set up that is not a million bucks. Thanks for the input.

Lets see your set up!

Al, for some cheap pre-filtering, use some of those filters I sent you! When you make your filtering setup, make sure you have a pressure gauge in front of each filter(unless you move to the bag filters). That way you will know which one is getting plugged up. Heating is a good way to get the water out and to help flow through the filters. I have also cut the WMO down with diesel. Feel free to call if you have questions.

I think I am going to want more of those Gimp. I'll send a PM later.
I want to learn about the bag filters before I spring a leak in my bank account.
I'm sure it has been covered. I'll search it up this eve. I can tell something is about to happen. My wallet is getting warm.

I have been trying to find out if bag filters are rinseable. Can you wash them in a solvent or do you replace them when they are clogged?

I was all bent on spin on filters. I don't see a centrifuge in my future any time soon. So I am looking at bag filters now. I am also waiting to see some new creations with the promise of pics.

So what is there?

House filters
spin on filters
bag filters
centrifuges
Anything else? I have been and will continue to browse the threads.

I have found my answer on cleaning bags.

Still interested in knowing if all methods are listed above.
