Very Bad Bypass Filter

[John With Beastly 302]

I have two antique tractors. A 1945 Ford 2N and a 1950 Farmall Cub. I was curious and thought I would do a search on Wix's website to see what the nominal Particle rating was for both tractors bypass filters. For the cub the Wix number is a 1153 and is rated @ 19 Microns which is not bad but this is a bypass why don't they use thicker media? From looking at the pic of the filter it looks like the media is of the same thickness as a standard 51515 and that filter is a full flow and it has a 21 micron rating. Then for my ford the bypass filter is a 51010 and it has a rating of 32 microns! I have a hard time understanding why Wix lables these filters as bypass filters when they are just full flow media in a Bypass case

When filters were first added to engines they were plumbed into the oil passage and returned to the pan. This system cleaned up the oil which allowed longer intervals between changes . Then the manufactures went to full flow and saw dramatic increases in life. They are bypass filters in every proper description..

I agree with you, I was just pointing out that in the Bypass filter world today the micron ratings are much lower and thought Wix could at least put more media in these filters to lower the micron rating.

The micron rating may be better than indicated. Wix doesn't have great detail on all of them.

If you see enough filters from Wix you can see that the nominal rating is conducted under the standard single pass test, but the filter isn't operating at the single pass test flow rate.

Anyway, cannibalize that filter and stuff a tp roll in there.

Seriously? Done it? I can't think of any reason it wouldn't work just fine. Plus, it might be a little more restrictive and for some old engines, that might be good. I'm thinking of the Willys Go Devil, whose oil fitler sometimes starves the main bearings.

I was looking at the dimensions of the can.

Gasket Diameters

15016 4.191 3.793 0.075
15480 8 4.448 4.134 0.157

The standard tp roll is about 4.5" "square" 4.5Hx4.5D

You would probably need to massage it a little to get the flow to travel the long path through the roll, but it might just work as is if you unravel a few turns and remove the center core. Grab a perforated center tube from a spin-on to slide in its place.

I've wanted to do this for a long time, but I've got too many filters of all kinds to play with and never got around to it.



I would think a metal and rubber washer would do the job on the top (leaving the cardboard tube intact) ..sealing the center well. The can would only be required due to the side port orientation for the normal "outside-in" flow. It will also allow flow to the top if you can shorten it a bit (washers taking up the lost space on the interior edge.

Once you set it up, it shouldn't require too much work to change the roll out.

I hope I communicated that well. It's been a while since I plotted this out ..so I hope it creates a spark on the receiving end.

Yep it is a whole different use of the term.
