Removal of DPF filter?
- Thread starter Daveh739
- Start date
I haven't studied the system but in addition to removing the filter it should be as simple as replacing the before and after sensors with simulators to keep the ECU happy.

Diy kits seeming to be more common every week. I see them all the time for between $1 and $2k i guess depending on quality of components and who's actually selling it. I've got a concern if you buy it from a less than reputable source and it don't do the wook as promised then the solution to correct is probably not very attractive.
i wouldnt mess with it if your not having a current issue. i have been running a l5p duramax 2021 purchased new just around 135k miles with no def dpf issues. but i use it for its intended purpose of towing. my tractor is almost 300 hours and has gone through many regens with no issues.
i wouldnt consider deleting just for the sake of deleting. if your having ongoing issues then sure it can be a thing at that point
if it aint broke dont fix it.

Although I tend to agree, there is that saying,
“The first race car parts were made about 4 minutes after the second car was built!"
Some people just like tinkering/modifying/customizing stuff…..even if it’s for "no good reason".
As a matter of fact, I “know a guy” like that
Don’t have any experience deleting stuff….. but I wonder if indeed, the DPF sensors are not much more than differential pressure sensors…. and, if so, …. then removing them from the old DPF and sticking them back into the circuit wouldn’t fool the ECM or UNIVAC or CRAY ….or whatever Gates and Dell have contrived…. into believing things are hunky-dory...?
(I.E., ..”Gut” the DPF and don’t disturb the sensors.)
(my M4700DT may be ”old” ..(ca 1996)… but it ain’t got no filters except the intake, fuel, hyd’s and oil, Thanks to my good luck finding it lightly used 8 yrs ago)

I wouldn't "gut" the existing filter in fear if having to undo and put it back in. Remember catalytic converter test tubes? What you would want ideally is a tube or muffler that will bolt on in place of the existing filter. You may need or want a muffler in place of the filter.
Sensor wise I suspect it measures pressure before and after the filter via a voltage or resistance value. The values should be near equal until the filter starts to restrict flow due to buildup. Whatever resistance you measure on the before sensor should in theory work in both places to tell the ECU no regen is needed. This assumes it isn't also determined on a timer.

DPFs are very expensive. Unless there is a big change that allows a secondary market to delete the tractors in the US like some Provinces in Canada, just say no.
Fwiw, other tuning has to occur to add significant power. Just removing the DPF won't make much of a difference.
If you are having issues with your DPF as in regeneration too much etc, learn more about how to run the tractor to minimize the issue.

If it's not broke, it doesn't have enough features yet.
How many have you deleted? Most of the time it’s the actual emissions components that cause problems. If they are not there they cannot cause a problem.
Not everyone wants a 47 year old tractor.
As a wild eyed clueless tree hugger my new car is a hybrid.
It has a DOHC direct injected 3L I6 twin scroll turbo engine married to a 48v hybrid electric motor. It has a 8 speed automatic transmisson with paddle shifters on the steering wheel. It is RWD with an electro-mechnical computer controlled LSD that thoughtfully puts 382 HP and 400 lb-ft of torque on the ground.
It also has too many emission, engine, driveline and suspension management controls to count. Things like piped in exhaust noise, active lane keeping, automatic collision avoidance, auto start/stop, adaptive electric PS, etc.
About the only service I am qualified and equipped to perform is an engine oil change. But when cruising with the top down and I push the Sport button twice and put my foot down it snaps my head back against the head rest, the fake analog tach and speedometer winds like a banshee, the infotainment system automagically cranks the volume up, and a big smile comes to my face. It is without a doubt the finest and most enjoyable automobile I have ever owned.
I have zero interest in recoding or deleting any of those features or owning an older vehicle that does not have them. I feel the same way about my L3901 HST tractor.
YMMV,

Is name calling necessary?
. Hybrids are a very good option for many people.Seriously though, I've never heard of any emissions since the 70s that have had significant issues on gasoline models. I wish that was the case for diesels. I've avoided diesel issues for the past few years by not buying the ones with the extra emission systems. I didn't need a tractor with more HP than my L2501HST, so I was lucky.
Anything pre 2010 should be clear. You don't have to go to the 70s.
Never done it but, I've seen the result of it firsthand. Turned a good truck into a constant problem and money pit. I think it had to do with the computer tune, I know the engine got way too hot afterward.
I'd never take the risk myself. Say what you want.
I bought this L3901 before the onset of my lung problems. Little did I know how beneficial that DPF was going to be. The old B7200 was unusable and had to go.Is name calling necessary?

It has turn signals and it also turns headsNice! Did it come with turn signals! Do they work?
I was sorely tempted by the Masserati Grantourismo convertible. It has a similar look and even more "sport".
But thats a $350K car and the only way I could fit one into my budget was something 10+ years old. That means lots less technology which I did not want. Plus insurance and repair costs are big ticket items so I decided to be "sensible" and buy another BMW. Even so the other old Hokie thinks I have lost my mind. She may be right....
