As I recall, there were two studs on the trans side that I hung the gasket on. I also used copper gasket spray to ensure a good seal. Of course cleaning the area first is a critical step.

I’ve got a 3126 and the same ballpark too. With 13k miles on the clock I swapped my oil pump(used school bus take out). And just for fun I’m running 10W30 as spec’d and it’s ok. 40psi at speed when warm but will flash the low oil pressure light at idle. I will switch back to 15w40 soon and I’ll...

I finally got me some new sneakers! First one almost all put back together. Had a hard time finding the correct tan color in flat locally, so I just went with black. I needed to clean up some rust that was beginning.

I’ll be shopping for one of the rugged Dell’s with the serial port.

That was the plan for this old laptop. Just to live in the truck and diagnose issues. COM port 3, yes I can see it in the device manager. I’ll have some time tomorrow or Sunday to mess around with it some more.

Yeah I wish I knew that. I’m about $200 into the setup I have now. What version Nexiq clone?

I tried the different J1708 and 1939. I think I’ve got a problem with the USB to serial adapter at the moment.

I’ll go try these suggestions and report back. Thanks!

I hadn’t tried the compatibility mode. I’ll query my local tech guru for that. Thanks for the suggestions. I’ll see what I can do with that. I really don’t want to buy another laptop for a dang serial port.

Understood…. I have three laptops. None of which have a serial port to include an old engineering laptop. That’s running Win 7 ( never connected to the web) and a newer running Win 11. I do have a MacBook, but would obviously be needing the serial adapter .

Hey all, Ive got one of the Dearborn adapter DPA III Plus units. I’ll put the picture below. But I can’t get it to communicate with a laptop at all. I’ve used two different laptops with different versions of software. Additionally I’ve got two different USB to serial adapters that you need to...

M1078A1 I won’t have a chance to investigate for a few days, but yeah I’m a bit concerned it’s a pump or bearings, or both. Last year I had the same issue with the low oil pressure light coming on at stop lights. I took the chance on a used pump from a school bus. Best case scenario for a 3126...

Morning all, Had a big dump of 20" heavy snow that's killed the power grid here. Internet was out. Cleaning up I blew a hard line on the tractor cleaning up, fought to get the plow on my truck without tractor help (not recommend) and here is where it got interesting. Plowed myself and one...

Nice! I’m love to install one on my truck. The entry price is kinda steep from what I’ve seen. I suppose a quick way to see if it will heat the cab is to run the unit. Turn truck power on and without starting the engine see if the HVAC fan will heat the cab. If that works then you’d just need...

I saw this post when I first found the site and read just about every single post here concerning these trucks. This was something I was (for a while) considering for my truck.

IPD? It’s not you…. It’s me. IPR… Injection Pressure Regulator I was trying to help with the OP’s issue but I’m steering the thread off track. Sorry for the sidebar.😬

I believe the grid heater is working. But I can check it. I wonder if there is a learning curve with the ECM for the new IDP, the old one certainly was not functioning properly. The ECM I’m sure was trying to compensate for it somehow.

Well, in the last week I replaced my fuel hand primer, fuel lines, IDP and high pressure sensor. Last night was in the low 30’s, this morning I started the truck. Initially It had a hard time staying running, had to restart three times. However once a good idle was established, it idled right up...

I will give it a try tomorrow morning and record the Speedo. Should also be cold enough for the ECU to prompt a high idle. Or, rather try to high idle.
