Anatomy of a Frantz toilet paper bypass oil filter

[Froadin]

Yeah, I would only run in bypass mode. But I am so tired of seeing all the buildup of crud in every auto transmission I pull apart. And filters for automatic transmissions are a disgrace!

 

[Chipstien]

The problem with puting a bypass filter on the trans is with any trans you have clutch pak material that wears off. How often would you need to change the element before the "grunge" plugs it up. You do not have high wear items like clutch paks in the engine. Just food for thought.



I too have thought about putting a external filter system on the transmission but if you neglect the spin on filter then the flow capacity goes down and starves the transmission. Therefore I kinda canned the idea. However a bypass could be plugged and still not detract from the normal operation of the trans. Hmmmm... ... ... .

 

[Froadin]

It would seem that the recommended setup is having a dual external filter setup having both a full flow and a bypass filter. This would work very well in that the full flow filter would catch most of the larger particals before the bypass can catch all the very fine particals.

I still don't like the idea of anything being able to reduce flow/pressure in an automatic trans though. So a single bypass filter would always help. And when it gets full of crud, well, you are operating just like normal. So no harm done.

JimMccarty, what happened to your text?

BY the way - I took time to actually measure the restriction in my original Frantz filter - it was 11/64 - the home-made one now installed in my current truck is 1/8...



Just a FYI...

 

[banzaitoyota]

Can I be added to the list? QTY=1

 

[Big_Daddy_T]

All I can say is WOW. Too cool gary. Very thorough.





Im glad my OCD doesnt include chemicals on paper.



Your viscosity is well above where it is supposed to be. That is impressive. Shows the oil is degrading much slower.

 

[Gary - K7GLD]

Well, actually, that viscosity was because of the STP I added to my oil... Blackstone commented on it, and stated that in view of my wear numbers, it was obviously not an issue of concern...

 

[Texas Diesel]

Gary, did Blackstone detect the STP or did you list it in your make up oil?

 

[Gary - K7GLD]

I told them it was in there - but I'm sure they woulda figured something unusual was going on... I had been using it in that '91 since the truck was broken in, as I have for years in other vehicles - so they usually commented on it, but said everything was obviously fine...



At this point with the new truck - 25,000 miles - I use one bottle every oil or filter change, started at about 20,000 miles, and change TP filters, add a quart of oil and one STP at about 2500-3000 miles - change everything somewhere around 5000-7000 miles depending on truck use and how bored I am...

Here is another site showing how by-pass filtration works.

Gary, you sold me on this. I'm going to get one, just got to figure out where to plumb the Franz into. I've got an oil temp sender in the port on the oil filter bracket.

 

[Chipstien]

For those in the GP, you should be recieving your filter(s) any time now. The last were sent today.

 

[Forrest]

Just got it ... . cooool fittings, including that swiveling mo'fo.

Cool! I'll keep a look out.

 

[Diesel&Donuts]

Got mine today!

Thanks,

Harold

 

[JSmith]

Got mine, thanks ChipstienOo. Oo. Oo.









Thank you too Gary.

 

[Gary - K7GLD]

I plan on taking some additional photos of my install to post here showing the attachment points for oil pickup and return, in case a few here are unsure as to possibilities - should be up in an hour or so...
