Oil & Fuel 2015 Branson 3520h DPF Issue

   / 2015 Branson 3520h DPF Issue #121  
Would anyone happen to have the Kukje p/n for the silencer for a 2016 4720h Branson handy? I run mine up to the high end of the RPM range but am only doing a lot of FEL or Backhoe ops so the exhaust isn't getting as hot as it should to burn that crap off....

Are you getting symptoms of a clogged DPF?

I'm getting the blinking DPF light, then after a while it goes solid...…

I run the rpms up and even drive it for 10 minutes or so, but I guess that just isn't enough.

A couple other people have had that and made it go away by running the tractor up and down the road at full rpm in high gear. You need to load the engine so the governor is calling for full power or close to it and pumping a lot of fuel. Probably for more than 10 minutes. So far the chipping I've been doing has provided enough high power operation to keep the lights from blinking. Or maybe it's going up hill that does it.

Thanks for the reply all..... Guess I'll just keep trying to get it hot enough...or eventually swap it out for a silencer...…..

I've had my light come on solid a couple of times before. Once it gets that bad, you have to really run the beee-geeezusss out of it to get it to clear out.

10 minutes will not do it.

Just free revving the engine won't do it either.

You have to put the engine under load AND max rev's at the same time. In the summer time I can do this by running my brush hog out in the pasture. In the winter time, the only load I can put on it is by roading the tractor down the road. I put it in high gear and run it flat out down about a 1.5 mile long dirt road. If the light on my dash is only just starting to blink, then usually ONE trip down the road and back is enough. But if the light has come on full steady solid, then it takes 2 or 3 trips down and back this same road, without pausing between "laps", to get it cleared out again.

There's no more doubt for me that my DPF is coming off. I don't want to hassle with it this winter. My only hold up is finding the exhaust shop to do it. I'd like to find one that would do the whole thing for me, drop it off and pick it up when it's done, but I'm not sure I could find a shop locally that I'd feel comfortable to do it. The welding shop I've worked with on other things doesn't really want to do it. So I'll probably just pull it off myself and take it to an exhaust shop, along with a new tractor muffler from TSC or similar.

Stopped by a local exhaust shop today, they wanted to see it before they'd know if they could do anything with it. So left work early, loaded up the tractor and hauled it down there. Guy isn't sure he can make the tight bend at inlet side, and he says he doesn't have the flanges. Wants to cut my pipes off my cooker and reuse them. I really wanted to save the filter as a bolt on piece, so I had it for trade in or whatever.

Does anyone that has made the swap to muffler have a part number for the flanges they used?

I did stop by the local Runnings store and bought a muffler for an Oliver 550, that does have a right angle outlet. But the inlet is straight. Was hoping to find a right angle inlet side, but nothing on the peg. This is the muffler I found:

I think it's short enough the guy ought to be able to make this work, can cut the inlet pipe down to almost the muffler body.

I'm sure I'll never put the soot cooker back on for my own use, but I'd like to keep it all "bolt on" swappable, just in case.

Summit racing lists 354 flanges. Surely one would be close enough to the required size? Or you can cut them out of plate. Summit also has bends and tubing.
Nice that you're keeping the ability to go back to stock. I do that with all my vehicles. When I sold my last modified turbo car I sent the buyer off with a car full of parts.

I happen to have the tractor in the home garage so I took a couple random pictures of the exhaust. Maybe it will help or at least give some ideas.

You fellas are to worried over "saving" the DPF muffler. IF, you take the "innards" out of it you can't tell the difference (other than you'll never have to worry about it plugging up) it doesn't smoke any more than it did before, doesn't really make any more noise, it just runs better. I got the idea for doing such from MY DEALER, he did it to his own tractor (3520) the only way to tell is to disassemble the DPF and look inside (who's gonna do that) besides it's an "off road vehicle" and only needed for import and a dealer to sell it new.I plan on keeping mine until one of us is dead so selling or trading it in is a non issue for me and even if I did in 10 years or so do you think tier 4 compliant is going to meet the standards by then. No. But you have to use your own judgement on how necessary it is. That's what I did.

I did the same as Hombre. Remove DPF Muffler and punch out the internals and bolt back in. Plug sensors back in and no lights on dash and no worries about DPF clogs. No noticeable difference in loudness of muffler but you will see smoke now at startup and occasionally under load, no big deal to me. Best part is the cost was ZERO and it looks factory original.
