Oil sludge is common on the intake side of the turbo. This is caused by not changing the air filter soon enough. The air compressor gets its fresh air from the pipe between the air filter housing and the turbocharger, when the air filter is dirty the suction from the turbo impeller will pull oil past the air compressor rings and it will settle and turn to sludge in the intake side of turbocharger. There are some bulletins on fixing the problem with a check valve and special hose on the air compressor intake piping. The fault code for the turbo wheel speed was an open circuit code so the engine ECM is not seeing a signal from the speed sensor. Usually a bad sensor or wiring between sensor and ECM. Test 4 in what Joey Mack posted would tell if it’s the sensor. Only weird this I ever saw was the turbo impeller shaft broke between the bearing and you could turn the intake impeller one way and the exhaust the other way.

As Terry said, Mike's son, also Mike Harbison assumed his Dad's roll in the old Mack world. Mikey is on FB as Mike Harbison.

IT MOVES!!!!! I installed the new pump(another story) and got it running. I was able to air it up, release the brakes and was able to push the clutch and easily slip it in gear and slowing inch the truck forward(can't go far). I pushed back down on the clutch and slipped in reverse and backed it up. Nice!!!! I released in neutral a few times and pushed down fully and was able to slip it in gear without any clash. I did it numerous times in forward and reverse. I then pulled the linkage all off, drilled the pivot bar for a cotter pin to capture the Z bar. I installed the grease zerk in the bar and put a couple clicks of grease in it and spun it around a few times to work the grease into the bushing. I then bolted it in for the last time and attached the clutch rod to the transmission. Now I need to recut the keyway in the pedal pivot rod and finish the machine work. Install pinch bolt detail and then split the ring. I need to install the bracket for the return spring. I am pretty sure I can modify the original bracket and weld it to my new arm to enable the stock spring to be used. Not onto the new pump. Ugh. I installed it and the given primer pump didn't work(ya, I knew that was coming). I installed the old bailing ring pump from my 237. It still had issues getting fuel up. I still have the pressure gauge installed in the fuel filter housing to watch. I finally got it primed and engine as started. The 20# I pumped up slowly dropped off like before. I pumped it while running and it went back up to 20#. Then slowly dropped again. I removed the return check valve assembly and investigated it. Nothing wrong I could see. Sealing surfaces were fine. I thought maybe I could shim it up. I had some .010 shim stock and cut a piece and put it back together. I could pump 30# now. After starting it would again just slowly drop off. Less of you didn't rev the engine. It would idle for as long as you wanted. I did finally get some heat in the engine and topped off the radiator. Tomorrow, after getting the other power steering lines made I am going to make a short fuel line and run it off a can and see if it keeps pressure. If not I am not really sure what to do next. I tested the Jakes, they work. After I get the clutch parts in for good, I can put the floorboard back in so I can tidy up the interior and keep moving forward on the front end.

If anybody is interested in getting there truck polished and some frame paint job for cheap message me

Glad to help.

ya and i bet Pfizer is already pissing themselves we see tons of unnecessary vaccines sold,,,,and this time its Bidens buddies making billions off the public,,,,ya baby!!!!!!!!!!!!!

I have all of those solders.. I just need to pick the one that wont melt when I crank the engine, on a day when it starts hard... 🍻

Speaking of King Fuacci.... He sure is silent about the Rat Sh!T virus that is slowly infecting people. Funny how all the states that have infected people encircle the lower 48... anyway, its Friday eve.. Have a good one.....

Superdog has passed away, but i think his son has charge of the trucks, you might google Harbison, that is there last name. terry look up mike harbison on Facebook.

normal solder is lead and tin. electronics solder has a flux core, plumbers solder does not and needs flux added to the surface before applying the solder to make it stick.

This weekend I am painting the frame black hopefully this weekend and polishing the air tanks and fuel tanks with the rims too

well i dont blame you i just poked around and yes many guys cover them,,,good luck

Yes Bob, I guess I can go to You Tube University. I prefer the Goeff Weeks Vocational Technical Institute when it comes to my KB-7...

wow that thing is badass missed it somehow thanks for that

try UTUBE someone might mention them

new generation.for a new generation,,,,im sure a good part of the people now dont really care what they look like .....long as you dont ask them to fingerprint any freight or chain up haha ,,,,but ya i get it,,,,mack really doesnt stand alone...on these ,,,,,but best of luck to them with sales...bob

Silver solder ? I will buy some. I have a common solder, but dont know what it is made of.

it looks like it spells out good,,lol.ithink thier glued in,,,,,im sure someone has better advice,the main thing is they were available,,,

I have used solder but I suspect silver solder would be better. At least you starting with all new and clean parts.

So here is my new field kit. No instructions with it. My guess is I have to weld the copper tab to the back of the power stud. Will solder withstand the amps, or will it melt ? I do have lead on hand if that is what I need.

thats discusting,,,,,where the hell do these misfits get off???? thats sacred burial grounds,,,,its like digging up thier graves,,,,,,clearly this assclown has got plenty of spare time,,,,,thanks for that,,,bob

well thanks for that,,,bob

I know the Ford Kuga well. It's known as the Ford Escape in the U.S. since MY2013, but as the Kuga in the global market. It was designed by Ford Germany, hence the German name.
