DIY By Pass Oil Filtration

[tygrrwoods]

Well, before I start I'm gonna give a little background information about me. My dad owns a hydraulic disturbition company, and I've been working there for a while. He sells hydraulic parts and builds power units.

So, I decided to order a AMSOIL by pass system, BK-13, as it sounds like a good idea. As I'm going thru the parts for the system, I know what most of these things are and seen them in stock at my dads company. So I got the bright idea. Why not just make a by pass system myself.

What I'm planning on doing is remote mounting 2 filters in line, series. The first filter will be a 15 micron donaldson. Its the standard filter that goes on my truck. The filter after it will be a 3 micron filter by donaldson. So basically all of the oil returning to the system will be filtered thru 3 micron, and not just some of it.

So, some input as to what problems I might run into with the design below would be helpful. Thanks

This is a head unit the filters would spin onto. So 2 of these inline.
Another bonus about these is head units, is that I would be able to put in a indicator that would tell me when the filter is clogged. Electronic or a visual guage.

Post some pics of these filters and associated hardware you plan to use.

If I read this correctly, this will not be a bypass system?????????????

Will this be just an oil pressure gauge?

The Amsoil bypass filter removes particles as small as 0.1 micron in size.

And it begins....

The Amsoil bypass filter removes particles as small as 0.1 micron in size.

It can but with lower efficiency. This was quoted from the web site "AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns." And, this "These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter."

Also, quote from their site "Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. "

So it might not technically be a by pass system. But it should do the same job as their by pass system is trying to accomplish. These filters are made but a major manufacture of oil filters, and automotive is major part of their products. Even AMSOIL sells them on their site!! If I need to find a 1 or 2 micron filter, then so be it. 3 micron is just one of their standard filters, and I havn't found a cross ref. filter yet.

The reason I believe that their system is in parallel is because they trying not to effect the flow rate as much. But that is just a guess, so something I'll be figuring out on monday with the guys at work.

What I'm most worried about is pressure, flow, and how much it matters that hydraulic oil differs.

Will this be just an oil pressure gauge?

It might just be that. All I know is that it is supposed to measure the pressure differential across the filter.

And it begins....

Hmm...what am I starting?

Good luck; I am anxious tio see your results.

im interested as well. on a side note, can oil be ran through an aux tranny style cooler? just a though while i was thinking of how this would fit.

Engine oil coolers have bigger fittings than transmission coolers, and most likely have bigger diameter cooling passage ways so that they don't clog up. Engine oil runs a lot dirtier than transmission fluid, since it doesn't have those detergents. Engines have carbon deposit build up which transmissions don't have. CNG, and LP engines run super clean compared to gasoline engines. Some have gone over 400k miles with pretty clean insides from what I've read.

How could 2 filters in series act like a bypass? If they would be in parallel, and one got clogged, the other one would allow fluid to circulate providing that it wasn't clogged too. Amsoil has another approach to all of this. By adding a bypass filter in addition to the existing filter would allow additional filtration without disrupting the normal fluid flow path.

There would be a bypass in the head unit. So when the filter gets clogged and pressure builts up to say 20 psi it compresses the spring and lets fluid thru.

What would that result in (1) flow rate and (2) pressure?

I'm not sure what the flow rate would be. But the pressure coming into the system would have to be 20psi or greater to by pass the filter. The filters that are standard for your cars have a by pass in them. It might be around 7psi, but don't quote me on that, just a guess.

I got into an accident on the way home from my trip. So, this project is gonna be on the back burned for a bit.
