    Gunnison HDT Sighting

    Who was it in the City Market / Walmart in Gunnison this afternoon....black singled with poly fenders.

    Based on concerns raised, after the pictures, I ran a ratchet strap, hooked the frame on both sides of the tire, and went over the mounting pipe...no wheel movement on the road, based on what the paint looks like where it's resting. To be clear, the piece of mud flap is attached to the framing that supports the fairing, behind the DPF.

    For what it's worth, not much, the tire is a 2006 vintage load range D original from the Teton. So, to your point, before I get anther wheel and put two Michelin XPS ribs on there, I have an Omega bimetal sensor meter I will hook up so real time temps can be verified. In 7 yrs, the truck only seems to want to Regen when going down.the road.

    The data is in. Ambient conditions, 95 deg, freeway rollers ( I 25 in southern NM), 63 mph. Stopped at a rest stop and hit all the rig tires with the IR gun as I always do. Fronts 125, rear outside 125 trailer 110....and that spare behind the DPF....109. Sheet metal and mud flap heat shield between the tire and heat sources, combined with the fancy aluminum backed glass on the pipe between the turbo and DPF seems to be effective. Also the passengers foot well is not hot any more.

    Presto ....... Chango

    It's bedliner. I may slip on it some day, but seems like it has pretty good texture from a 3/16" roller.

    Presto ....... Chango

    We have been running around on our summer adventures looking a bit, well, unkept and in primer. Today, that changed, at least as far as the deck is concerned (rear bumper still in gray primer) Presto and Chango

    I have a beginnings of a sheet metal heat shield on there but I need to add a lower flap to block heat from the bottom part of the DPF. There is a 2" or 3" air gap between the sheet metal and the pipe. Plus, I have some of this Heatshield Products Armor exhaust blanket on the way along with the steel ties to contain some of the DPF regen heat.....maybe make the regen more effective? I am also putting this blanket on the exhaust pipe from the doser to the DPF ( the floor gets pretty hot in the cab ) What do you think about wrapping the DPF itself with this blanket material? I have seen working trucks carry a super single spare in this same location. To address the wheel bouncing around, i have to machine a spacer and or bring out a stud or two from the many that are available behind the tire on the frame. My welds, I can say they are better about the time I am finishing up the project. 😃

    While I was doing my DPF remove and replace for the $130 cleaning, there was this nice space behind the DPF that was just bothering me. So, what could I do with this space. Its quite large, about 34 wide x 33 high (to maintain the same ground clearance as the DPF and fuel tank) and 27 deep. The last guy must have put his tire chains there..... guess the chains don't mind getting toasted by the DPF. For this summers adventure, we are adding a 42 gallon Barker gray water caddy, but where am I to put it? Solving all that is bothering me at once. Drop the spare tire from the coach and put the caddy in that HUGE volume under the very rear. Now, that to do with the spare.......ahhhh - it goes behind the DPF. I did some CAD calculations (Cardboard And Drawing) in this case.....it fits. Actually, I can carry two spares now. This is my tacked up fit check This is the finished design with heat shield

    DPF DIY Service on D16

    Update - The threads in the cast pipe were fine. A big win for me. So, the reason I pulled the DPF out and cleaned it was regens seemed to be happening more often over the last two summer adventure seasons. Based on the doser gasket, the doser function may have been the cause.....things may not have gotten hot enough to do a decent regen. Looks like the path for the 7th injector to put fuel in the exhaust path is almost blocked

    I got the rest of the *^%&$$ bolt out. Did the "weld a nut on" three times....got maybe a 1/2 turn out of it total. At the point where the bolt was flush or below the surface of the cast pipe, drilling became my next step. So, $35 for a Harbor Freight right angle air drill and off I went. Did everything right, no broken bits. I will have to put a Heli-Coil in as my drilling got into the minor thread diameter a little. I used this thing call a screw remover to get the last bit of the ^%$^&^&*^ bolt out. first time I used one of these but it worked good. Never gave me the feeling that is was going to get itself stuck in the hole. I see this as a win since there are no broken off tools in the hole right now.

    I think this is a blind hole for these two bolts. That is they don't break into the exhaust path.....seems like if they did, you could never get these out, even on a good day. This is my weld plan Smashed a penny pretty thin on the anvil. Drill hole to match bolt diameter (this is if I get carried away with the MIG so I don't weld the bolt to the cast) This copper washer goes on first. ( i know...ain't much copper in a penny any more) Next a steel washer and small tack Next a little thicker/bigger steel washer with a tack and puddle weld the whole deal Next a nut, little tack outside and puddle the inside full I like the quench idea for the next step Hit it with a hammer Then get a box wrench on it and do the tighten loosen thing and hope it cooperates. So, looking forward, when I put the new bolts in....anti seize or is there something that will take the heat better......Teflon tape, or ???

    I took apart the DPF and had it cleaned since I don't know how long its been since it was done and it seemed like the regens were happening more often. After it was baked out, contacted Volvo for gaskets to put it back together. Volvo really likes the stuff they put their name on, so got aftermarket on line for 20% of what Volvo wanted. Now the fun starts. I talked to the mechanic types at Inland Kenworth where I had the DPF baked out. They said to check the doser (7th injector) and clean the carbon off to insure the regen process works and get as hot as it should. Ok, no problem. Again Volvo wants $85 for the doser gasket kit......aftermarket $20. It seems the doser had never been taken off and the two metric bolts (less than 1/4" diameter) that hold the doser on had made themselves one with the cast iron pipe that is Vband clamped to the outlet of the turbo. So, I do my 50/50 trans fluid and acetone to attempt to penetrate the threads. Didn''t really work too well. You can't get to the bolt to add any heat. So, one bolt came out after doing the loosen tighten dance all the way out. The other one, well, most of it stayed with the cast pipe, but I got the rest of it. By the way, a mule skinner would have taken notice of my descriptors when it was obvious the bolt had been twisted past its material elasticity limit. Unless there are suggestions, my path is to weld a nut onto the 3/16" of exposed bolt. If that doesn't work, drill it out and don't break off an easy out in there. Or maybe drill out both of them and put a more substantial diameter bolt in there. Progress pictures to follow

    Shock Removal

    My issue was the shock bushing had "Michigan Loctited" itself to the bolt on all 4 lower mounts. I put an air chisel on the bushing next to the rubber part for a minute or two, the Loctite turned to powder and I was able to get the bolts out. New shocks made a big difference, not in the ride but in the side to side sway, especially in corners. Doesn't feel like it needs a rear sway bar any more.
