DPF removal on C9

satkinson · Jan 2, 2020

Hello People

Just sat watching gold rush the other night and noticed the guys were having problems with the dpf throwing codes and shutting down the engine (Cat C9) on a large water pump.
After much messing around with the machine the mechanic decided to remove the full DPF/egr system he took off the NRS cooler and blanked everything off. What amazed me was he got her up and running no problem.
Is this really possible or just TV bs I have a few machines with the C9 with DPF not ad blue and would love to rip it all off, I'd like to hear other peoples thoughts on this.
Cheers

Made for TV dramatized BS IMHO, although I haven't seen the episode in question. Removing the DPF and blanking everything should've resulted in the diagnostic panel lighting up better than a 4th of July fireworks display.

In an-emissions regulated market like the UK are you aware that no dealer would want to/be permitted to (*delete as appropriate) work on any machine if all the emissions equipment had been removed/circumvented/whatever.? So you could kiss all your Finning support goodbye in a heartbeat.

I don't watch the show nor seen the episode either but I'd say TV BS. However I do know a local guy that deletes DPF equipment on on-road trucks all the time. He has the software to re-program the computer so no idiot lights come on. Not that I am advocating anything..

Talked about here.

Steve, this is what the US laws say about deleting DPF. I'm sure there must be something similar in the UK atlhough I'm not familiar with the fine detail.
Confirms what I said before. Nobody will want to go within a mile of it to do service/repair work after the delete, and no-one will want to buy it when you eventually try to move it on from your ownership.

Over Christmas was talking to a guy who was a salesman at a Volvo dealer in Southern Alberta. I asked him about the Volvo machines on Gold Rush. He said they lease the machines but it's next to nothing. What was interesting though is he said Volvo sent a small Seacan with all the filters, oil and maintenance items required to Parkers site. Near the end of the season the dealer and some Volvo reps. were on site and noticed the seal hadn't even been broken on the seacan! He also said there is a guy who watches every episode just to count how many times the Volvo name is shown. Apparently there is a minimum number they have to show it but he wasn't sure of that number.

I can just imagine the ramifications should Caterpillar get ahold of a PSR from a deleted machine.

Plus all it would take is for a dealer tech to flash the latest software into the ECM during a routine shop visit and your machine will be a paperweight.

I hate this emissions stuff as much as anyone else but unfortunately its here to stay so we need to adapt to it.

Cmark · Jan 4, 2020

I've not seen the show, but can anyone tell me which C9 has a DPF? I've never seen one.

92U 3406 · Jan 4, 2020

It'd be a C9.3 wouldn't it?

Nige · Jan 4, 2020

Having had a few PM conversations with the OP over the last year or so about various things unless I’m mistaken the engine in question is most probably in a late-model track-type tractor.

EDIT: Sorry just realized you were talking about the water pump engine.

That would make more sense.

satkinson · Jan 5, 2020

Yes it's a c9.3. To be fair if it's a set up it's a pretty elaborate one cos the guy carrying out the up grade certainly seems to know where to go to, he definitely rips off the NRS cooler and blanks everything off, he even makes a new exhaust section to replace the dpf il try post a link to the video look around the 28 min mark, see what you think

Hi Nige
It wouldn't worry me complying with any regulations as all our work is our own contracts, we dont answer to anyone.
It also wouldn't be a concern regarding the Cat main dealers, I carry out all my own repairs and anything we cant handle we have a good ex main dealer independent can jump in and sort 99% of stuff.
There is no law can stop you from making these alterations to off road equipment only a client can specify a certain level of emissions control.

Nige · Jan 5, 2020

Steve, I understand that, but what happens when you want to sell the machine.?
In its modified state it ought to be (in theory at least) the proverbial hot potato that no-one wants to go within a mile of.

Having watched the video - total BS............if it was that easy everybody would be doing it, not just some wizard buch mechanic up in Alaska.
It begs the question as to why the f**k did they buy a pump for a remote job site with an emissions package on it in the first place.?

Welder Dave · Jan 5, 2020

Since when does working a machine harder cause rad hoses to blow and track links to break? It seems like an on going theme on Gold Rush. The excuse is that's what happens when you have unrealistic goals and deadlines. I can see why Fred Hurt left the original show. His comment was he wanted to be a miner not an actor. Too much scripted drama. Yea rad hoses can blow but not just because you're driving a loader faster and tracks links don't just come flying apart driving an excavator across the site.

92U 3406 · Jan 5, 2020

Its what happens when you don't maintain and look after your ****.

Or a TV producer needs some drama to keep viewers watching.

satkinson · Jan 5, 2020

I agree theres alot of bs on gold rush but I doubt any of the producers would have the mechanical knowledge to create a scene where a c9 engine is de emissionised due to soot load problems.
If that fitter did rip all that crap off the engine and get it to run correctly I'd say hes a good man and well worth his wages.
I agree with nige that taking a pump up there with dpf on it was a foolish move.

The part they are missing is they would have had to have an aftermarket software program lined up. Nothing that mech can do with a OEM flash file to make an engine run with a bush delete. Engines are deleted every day as we know it’s just having the correct software after the hard parts are removed.

I agree tier 3 would be better but I’m not sure about industrial engines but we are over 10 years of tier 4 on those 9.3 Cats so finding a tier 3 15-20 year old engine is not ideal in my mind either. Pick your poison

92U 3406 · Jan 5, 2020

Having worked at a rental store and playing a bit with power generation my personal observations are people still think "old school" with engines. These Tier 4 engines NEED to have the **** worked out of them. Running at 30% engine load is just ruining the equipment. Why do you think the days of big bore, 16L on-highway truck engines are over? Because its too much engine for a measly 80k lb rig. I've lost count of how many times I'd go to a generator for emission codes and come to find out they're running the engine at a 20% load? When you explain to them that they created this problem by renting a generator that was vastly oversized for the job I'd get the deer in headlights look.
