What a cool truck! Did you put those LED lights in or was it like that when you bought it? Let me know if you need help with pictures in the future, I can usually figure that kind of stuff out. We love pictures here!

I've always wondered where you get replacements for those as they tend to get eaten by mice. Maybe make them out of sort of paper mache? Best of luck

Do you have a iPhone? It might be the wrong format or something, I can DM you my Email and help you out if you want

Sounds like a Hogans Hero's episode. Thanks for sharing

What an eye catcher! Thanks for sharing

Did they have the plastic dash in 1974? I thought they went to that later

Was the air for pressurizing the fuel? Pressurizing the fuel tank then counting the drops when the pump gets into the right position? I've never spill timed anything but the process seems cool

Spill timing can seem like magic but it shouldn't really be all that hard with the right tools and knowhow. Engine should run better too since the timing moves a bit after the gears wear in

I didn't know that about the Cummins low flow engines. I know that they were mostly hated around here in tractors, they seemed to go through fan belts frequently and you'd have to keep the radiators sterile to keep them cool. The weird oil thermostats they put on Cummins later weren't much liked either

Got around to getting that tire off. What do I look for steering and kingpin wise while it's off? It felt good but I don't really know what I'm looking for Edit: I don't have a proper "truck jack" so what's the safest way to do this? Two bottle Jacks was all I had at the time

I've heard a bad throughout/input shaft bearing can do weird stuff like that too. Pulling the transmission top cover off first like Joey said seems to be the best way forward. -Good luck

Are F700 and R700 similar chassis? Almost odd to see such an Aussie spec truck here in America, wish that had a vid of it running that would be sweet! Edit: Awesome Farr air cleaner too!

I used to think that same thing until I got a truck with a Mack 6 speed (twin stick). You somehow are always in the right gear and have plenty of power without doing as much shifting. Biggest problem is at 2,000rpm doing 60, 45mph at 1600 is just right but I don't do much highway driving.

That's right it was you Bob. I don't know if grain pups are different but the ones I have seen don't seem to have a detachable "5th wheel" like LTL companies use. This is more of what I am looking for

A couple other odd questions I've been meaning to ask are; will reversing in top gear harm anything? Rather than turn around in the field (got stuck once) I've opted to back up the 1/4 mile to where it's close to what's being cut. I know these 6 speed mack transmissions are pretty tough but will shifting through the gears in reverse cause any damage long term? The other question is about pup trailers (doubles? I'm not sure what they are called elsewhere) I want to get one for this truck but I've never driven anything with a pup trailer, what are they like? do they pull hard? I thought I remember someone on this site worked for FedEx at a time and pulled doubles but don't remember who.
