Also, does the bad ECM’s smell burned? I’ve had several that you could smell it as soon as you unplugged the connectors. Some had melted pins even. Also look and see if there is a bracket that’s is bolted to the air compressor head that holds the chassis harness before it plugs into the engine harness at the big green connector. Seen the power wire for engine ecm rub and short out on this bracket. Usually it blows the engine ECm fuse but not always.

Carefully check the ground stud that’s welded to the frame behind the battery box. We have seen issues there with broken eyelet/ring terminal ends on the ground wires. If your battery box is on the driver side we have seen people remove transmissions and not put the battery cable brackets back on the transmission and found the positive cable shorting on the frame and various other places causing engine to cut out and /or die. Check and tighten the power and ground cables on the cab pass through by the wiper motor on the fire wall. Do the same on the inside above the accelerator pedal. You have to pull down the duct work with a T27 screwdriver to get it it. There is an unused open ended connector for heated seats by the inside pass through positive cable stud , I’ve seen the negative wire in this connector touch the positive stud and cause crazy problems. I think I might trust a TEMU or eBay ECM over a used Mack /Volvo one. The rubber insulation washers on the ECM shrink after a couple of years and the ECM just sits there and shakes its self to death. A used ECM could be on its last run as any given moment. If the truck was idling up to 1000 on its own then there was definitely a low voltage issue causing this. Usually when everything is perfect and new batteries and new alternator the voltage on the display is 13.6 or 13.7.

If it cranks for exactly 3 seconds and then quits cranking like you let the key up. Thats a sign of crank shaft and camshaft sensors mismatch readings. Surprisingly it won’t set a fault code for this.

Oh, oops. I posted the removal of input in the 300 thread. Easy peasy.....

Won't reach far enough. Once I get the template and holes drilled it won't be such an ordeal just shoving it in the hole. If I had to hold it for a long time I would be in trouble. A bit of progress tonight after dinner with Karen. I got ambitious to see if I could get the input out of the transmission. Yup. Thanks all for the push to just try and knock it apart without any fancy tools. I watched a YouTube video of a guy doing it like mentioned. Few smacks with a hammer and it all popped apart. Worse part was getting snap ring off the front. Had to mangle it but a new one comes in the kit. Googled kits and found local Pete dealer has Eaton kit for $260. I will be getting that tomorrow after work. Pt 2468 has everything and more then I need. https://ohiopeterbilt.com/products/fuller-kit-clutch-install Question for the masses: The plastic 3/16" fuel return line. Mack part only? It is reinforced plastic but only slips on fittings, no ferrel or clamps. Mine is pretty rough and needs replaced. I did get the crank hub installed the other night and balancer is on. Just need bigger torque wrench to get to 300ft/lb. Buddies only goes 250#.

Survey of Pres. Trump and Iran. Head to the bottom box on the site and scroll for the different tables. .....Hippy https://scholars.unh.edu/survey_center_polls/939/

He really IS a retard!

Looks are... meh. Maybe itll grow on me, but im still working RD's and an MR.

Single stick, i wish it was a twin stick. Multi speed reverse is great for our application. This mixer gets a 2 section hydraulic pump running off a pto on the rear of one of the countershafts. Its tucked in real neatly between the driveshaft and the left frame rail's lower flange. Hydraulic tank goes on the left side of the mixer, and 2 suction lines will loop around over top of the left frame rail into the top of the pump, while the two pressure lines will come out the bottom of the pump and come under the frame rails and back up to run along the left side of the mixer to the control valves at the back.

Ive seen her many times.. Smart Lady....

Can’t you set up the engine crane in your pick up bed facing the tailgate ????

Twin stick ?

Excellent thanks

A few of the pictures wont upload, but you get the idea...

Title says it. 1988 RD690ST project. Truck needs very little, it was a Locust Ridge H&K truck we bought a number of years ago. Cab was green when we got it, we painted it white and its been sitting long enough to grow some... patina. They put new frame rails in it and im guessing rebuilt the engine not too long before we got it because you touch the key and it fires up and perks along nicely. EM6-300L with a 7 speed Mack transmission. Currently were working on renovating one of our old mixers to for this truck.

The ones that I marinated in ginger ale and orange juice didn't really take on the flavor of either one, they actually tasted pretty bland. I'm going back to the regular rib routine - peel the membrane, coat it with the rub, put it in the smoker. They're always good.

Bet the trucks didn't feel a thing. We've all done it.

Wow, I could use a crane to hoist my stew pot from the hand truck onto the stand. I got a hand truck to haul it from the shed to the stand when I got the new bigger, stronger, faster stew pot but it's all I can do to get it from the hand truck up onto the stand.

farm I help out at to keep busy there are dumpsters parked . right now there is a dumpster from a metal fabricating shop. at least two floor cranes are in it besides countless pieces of steel. makes me sick to see the two cranes in there. I can't use them or store them. two 5 gallon pails ;one full of sockets another full of wrenches. the waste in todays world.

towels/blanket on cab cowl =2x4 or pipe cowl to radiator and a chain hoist to lift the steering box. one steering box /dozens of brake drums etc man handled ;you end up like this old man !! F-- K it use mechanical devices to save the only back you have. don't want to think or count the drums/ steering boxes and whatever else I did.

Pres. Trump needs to get Katie in his cabinet somewhere! LOL!

If yours is a Sheppard, I've done it a few times, and whipped my butt each time, I did get them in, however. Being on a cabover and working under the cab and in front of the wheel was no fun.

you sure put the pressure on with those pictures LOL being an old fashion Polish Catholic boy who gives up meat for Lent!! LOL I'll go back to my tofu! LOL
