    What did you do with your GMT400 today...or yesterday....

    How many miles do you guys get out of them. I can’t remember any issues of them wearing out real soon so long as they get greased ok. I know a couple guys who used to pop off the boot, use a penetrating oil flush out any old grease then grease it &put boot back on. Doing that once each 50k...

    5.7 diesel up and running

    Cat definitely uses split lock washers, internal and external lock washers. They just don’t use them everywhere. Only where needed and the best type for the area. Old cats vibrated so bad that they had a ton of problems with split lock washers breaking, then the bolt/ nut loosens up. When at...

    What does the optical eye sensor on a injection pump do?

    Ok. Correct there is no optic sensor. You have a fully mechanical ip (injection pump). The TPS (throttle position sensor) is exactly for the TCM (transmission control module) to help control when the trans shifts. Adjusting the TPS: Key on, engine off. Battery needs to have 12.6 volts...

    What does the optical eye sensor on a injection pump do?

    Please post multiple pictures of your two pumps, including the id plates. There is some confusion in the numbers and descriptions.

    5.7 diesel up and running

    The glow plug relay. Looks. Same as 6.2/6.5 early years. Is it the same or did you just use a 6.5 on there?

    Harness to pdm

    Sounds like one of the wires doesn’t have the little tab in place that holds the pin securely in the connector.

    5.7 diesel up and running

    The issues of the 5.7 are known, so hopefully you can get a long life from this one. Is this the DX model? I used to recommend the Bosch 80034 glow plugs for this and the 6.2/6.5. I stopped when a lot of issues started popping up, including when mine snapped an element off when running and...

    Square Body Steering column Swap

    Swapping the engine, transmission, harness differences, going to have to add a second fuel line it goes to the bottom of the fuel tank for the return line, change the sleep, change the steering column. Are you sure isn’t gonna be better just to sell this truck and buy a different one? Might be...

    How do you all get 6.2s to 300K miles

    Make sure if there is ANY play in the hinges : when the door is open, lift up on the end of it and feel for freeplay as it goes up & down. There should be NONE. If there is some, replace the bushings and possibly pins as well. It’s annoying but required. Doing them by yourself, you might...

    Problem on my Winnebago, 6.5 L65. Potential fuel leak back and bad battery?

    Can you make a video of it trying to start, post on YouTube and link it? That helps sometimes. Are you getting fuel out the metal injector lines? Do you have the clear tubing on the ip return line?

    Seat Interchange-- OBS into Square Body, etc.

    Oh, another option to think of- with power steering, ya might not need that large of a steering wheel. Momo, Grant, etc. you have to buy an adapter piece with each.

    Seat Interchange-- OBS into Square Body, etc.

    There’s a company called yearone.com that sells all the components for folks wanting original. I think they are nuts because even when I was skinny the gm bench seat was as uncomfortable as it gets… Squarebody floor is excellent (if not rusted). You can take some 1/4” flat bar that 2” wide...
