I知 Stuck

[birdmandave]

Pardon if this is not the right place to ask but need as much experienced advise as possible. Have a Branson 3725C with 37.5 hours and caught by the DPF. I failed to recognize the warning, and after attempting to start after stopping for a break the light flashed, went solid and now won稚 start. After much research I now know the error of my ways by not keeping the RPM痴 over 2K while operating. I contacted a local dealer and was told to remove the filter and blow it out. I知 very mechanical, have plenty of tools, the big question I could use advise on is this a DYI project or something that must be done by a dealer for warranty issues?

Thanks.

There are some threads about making up a "temporary or test pipe" and while no one should say to just forget
to install the filter after it gets cleaned out things do get put off some times :laughing:
Also it might not just blow out without some solvents or heat.
Good luck

"the big question"............The BIG question is what does this mean and or stand for>>>>>>"I知 very mechanical", maybe it's bad language on the Klingon's planet Kronos......

I was wondering the same thing about that. As for the tractor issue, I think your going to find the warning light will need to be reset and a manual regen will need to be done, and most likely by your dealer. I am wondering if your dealer misunderstood you and was thinking air cleaner and not the dpf when he told you to remove it and blow it out.

One cannot "blow out" a DPF! You have operated it to the point of severe clogging. The shutdown, and resultant no-start condition, is programmed in in order to keep the operator from TOTALLY screwing up the DPF. Dealer will have to reset (and they WILL make sure that it does a proper/full regen).

Interesting that you could get it to this point with such low hours. Had to work hard to accomplish that!

 

[birdmandave]

Thanks all for the replies. Not sure what happened with typing and foreign symbols. Based on the feedback I will be reaching out to other dealers and not mess with it. Guess I’m just not running it as hard it wants to be.

There are companies that offer DPF cleaning. Even Cummins does: DPF Cleaning | Cummins Sales and Service

I removed the DPF from my (TYM) Cablea's LM45H at 12 hours. Took about 30min to take apart the canister and drive out the filter and put the canister back on. Now has 125 hours no problems, no regen.

If the tractor's stuck there's an emergency bolt on the manifold that you can remove to get enough exhaust flow to move the tractor. That's how it was explained to me by my dealer. I should put some anti-seize on mine just in case. Nickel based to avoid potential damage to the catalyst.

So you gutted your DPF? What's that going to do to your warranty?

That's good info to know, ericm979:thumbsup: (one should never really be totally stranded)

As far as warranty, They would never know it was removed unless they take the canister apart and there is no reason to do that. It doesn't give any codes and doesn't have to regen. I kept the filter in case I would need to put it back but don't see a reason to. I left the cat as it was. I don't know if it would help to remove it, it has plenty of power as is. It will roll coal now under a heavy load.

There is nothing programmed on the 3725. There is no computer. None. There is only a "data logger" that compares the input sensor pressure going into the filter to the output sensor pressure on output of the filter. If the difference gets too great, it lights the light on the dash. That's it.

There is no way to "manually regen" the tractor. It is a continuous regen, think of it like a catalytic converter on a gas powered vehicle. It has to get hot enough for the catalyst to "cook" the soot residue out of the filter. That's why they say to run the rpm's up above 2000 for a good portion of your operating time.

The OP has plugged his filter with soot. Don't know what his elevation is, but if he's at high elevation (Colorado), the tractors come shipped tuned to sea level. That could soot up the filter in a fast way.

OP, contact your selling dealer, they should be able to talk you through taking the bypass plug out to get the tractor to run enough to get it on a trailer and get it to the dealer. Probably needs a tune check out, and a new filter. All should be under warranty.

And hop on down to the Branson forums, there's a few Branson dealers that are active in that forum that are very, very helpful.

So this is a DOC system not a DPF type? Big difference then on what needs to be done to fix it.

 

[ericm979]

It's a DPF per the manuals.

If the dash light blinks every 2 seconds the DPF needs a cleaning cycle. Which I think means run it hard for a while- the shop manual doesn't say. If the light is on solid the DPF is clogged. If your light didn't go through the 2 second blinking phase something might be wrong. There's also a .5 second blink rate to indicate a sensor malfunction.

The "rolling coal" may clog your cat.
