Dpf filter

I need to get my dpf cleaned. Does anyone know how to take it apart. Do I take all three clamps off to pull the filter out? Thanks for any insight.

 

I am gonna drop it out and take the whole unit to the cleaning place and let them split it and put the new gaskets in it and what ever else. The guy at Volvo said its not hard.

 

I took the dpf off and split it and had it cleaned. Not much life left in it. But it is a DIY, easiest thing I've done. You can't hurt it unless you take a rod and a hammer and drive it down through the filter.

 

You can't clean it yourself, you have to find a place that can clean it and test it. I didn't have time for pics because I needed back on the road. But on a Volvo 670, take off the step with the heat shield and the cross member behind it in front of the dpf. Unhook the exhaust and on the inside of the frame unplug the nox sensor and the other plug near it. Cut it free of the zip ties. I tie the wiring harness together to keep it out of the way. Two other notes to make it easier, take off the plastic piece under the door and take off the black fender well. It gives you a little more room to get to the exhaust on the back side of the filter. Get a piece of wood and a floor jack and get under the filter. You need a 10 mm Allen wrench to take off the bands. I held the filter in place with a nylon ratchet strap while taking off the bands. Loosen the strap and pull the filter back a little to clear it then drop it slow and work it out. Take it out in one unit. It weighs about 125 pounds. I was told twice that much from Volvo. I took it out and put it back without help so I know its not near 250.

Now unhook the stuff on the outside. I couldn't get the sensor out of the outlet pipe but it didn't matter. Next I drew to straight lines down the side so I knew how it lined up. Then try to work the clamps loose. I had to fix the threads on one, I reused mine but one mechanic says he replaces them everytime. But I want to try and save $57 per clamp. But after the clamp comes off the section lifts right off. The main filter sits down in the lower pot, its the third piece you take off.

You need three dpf gaskets, two exhaust gaskets, and any bands you want to replace or need to replace. It cost me $328 to have it cleaned, $48 a piece for dpf gaskets, $24 a piece for the exhaust gaskets and dpf clamps at around $57 a piece. That is about all there is to it. Volvo estimated labor at $400 and three days down. Until they break screws off and after they screw off labor would have been a min of $600 in my opinion. Seen it to many times. Good luck to anyone who does it, its a piece of cake. Take your time and anti-sieze everything when you put it back.
