The Heinz

Sometimes I need a bit of correction, especially when my mind is outrunning itself. Happens a lot with how the front counter is...

I misread that part of the post, I just had a customer ask about the door tags and my mind was stuck on that! Yes, for the frame tags he can just get the decals separately, we usually have most of them in stock.

Your best bet would be to contact your local Mack dealer, there's a form they have to fill out with information from you and submit with an eSignature. In the past it was a PDF that had to be notarized.

Not 100%, but the brake demand sensors near the brake pedal are usual suspects for issues like this. I've seen them cause loss of power complaints lately, so I would look into that/have a SMART shop look into it.

The part number for your hood is 23397375, and it looks like you need to replace the springs as part of a supersession; springs are 82392414 QTY 2. I don't have one in stock, nor does anyone in NC as far as I can tell. They ARE available from Mack however.

Noted! I guess that valve does make a difference. Joey, fjh, and the others will have better answers for the lack of boost, but I know the CAC hot pipe (passenger's side) has a bad tendency to leak there, requires replacing the two blue boots and all four clamps. Could also be something in the EGR system causing a boost leak too,

It's really common around here for newer cement mixers and heavy dump trucks to have a second steering gear on the passenger side, but the setup is very different from this.

If I'm not mistaken, the overflow valve screws into the head as the return-to-FF Housing side. This is me guessing as I haven't worked much on this particular setup, but could the overflow valve stick open and allow the fuel to drain back earlier than needed (Someone smart please help me out!)

I don't think there's a way to do that, and I don't think it would be a good idea given how the DOT stresses all drivers wear them while the truck is in motion.

It certainly helps! #4 should be the return to the pump, Impact describes it as "FUEL FILTER BRKT-FUEL PUMP," while #8 should be the feed line from pump to filter, described as "FUEL PUMP-MAIN FILTER." Both of those banjo bolts use the same washer, Mack #20852765. The overflow valve according to your VIN is #21458307 should you need it. Sorry for the late reply, I'm now a Front Counter Salesman, so I am much, much busier than before. I've already had the privilege to order and quote parts for several older Macks, including an 80's DM.

I didn't have a VIN for a 2010 CXU with an MP7, but this is from a Granite of the same year with an MP7. Number 10 down there is an overflow valve on the return side, I don't remember if that can cause your issue or not. We never reuse these seals, but we are a dealership, so take that as you will.

I looked into some aftermarket air cleaners for you, but in order for it to not be $1000, you might need to check some scrap yards or parts trucks out! Even PAI is proud of their air cleaner. Were the screens added in the ASET engines?

You can try going here and contacting Parker dealers nearby, I don't know anyone who would specialize in this stuff sadly.

I can only assume Teledyne sold off or closed their hydraulic branch sometime after your truck was made, because they had absolutely nothing about hydraulic systems on their website. I contacted Parker to see if they have anything, it's worth a shot.

It likely won't have a filter, but it might have a screen in the water manifold hoses, I don't have a picture at the moment. I don't think those need to be changed all too often though.
