Well do you know how she pulls yet? -
1979 cabover tilt ram

Glad you got it working. I think you mentioned your system has fine mesh screens in the fittings. I could see this being the blockage point with cold hydraulic oil. -
1979 cabover tilt ram
JoeH replied to RS Disposal's topic in Exterior, Cab, Accessories and Detailing
We got our truck with 415k miles, so no idea how it was from factory, but this is how it was routed when we bought it. "Push" function first T's into the passenger cab mount latch, then splits to go to tilt ram and the driver cab mount latch. "Pull" function just goes to retract the tilt ram. When the cab comes over center and starts coming down on its own weight it creates enough pressure on the "push" circuit to force the latches back open. Once the cab is seated, the springs on the latches hook the cab to keep it locked down. I assume your truck is the same way, but yours is 24 years older than mine. Not sure how the "push" circuit creates the resistance during "pull" function to open the latches, there may be a small orifice the oil has to pass through in order to return to the pump. Not sure why you're having the problem you're having! Something must be acting as a check valve somewhere, or the cylinder is binding! - Today

Refinishing an 89 superliner
Joey Mack replied to tegra1027's topic in Antique and Classic Mack Trucks General Discussion
You can adjust the sending unit. If it reads too low, bend the arm down a little, too high,, bend the arm up a little, put it back in and check it. It's important to make sure the sender is clocked right. So match mark it before removal -
They're polished aluminum wheels, old Alcoa wheels. I was finally able to find studs that are the right length for them. The BWP studs seem to be the longest, because they don't have the really large chamfer on the lug nut end (which makes the thread length a little too short) that some of the other brand studs do. So it looks like I'm good now. Thanks for the help. I was able to get new window kits for the vintage Stemco caps on the truck. The 5999 ones fit (2 3/4"), and all of the screws came out ok. I guess mine were completely painted over at some point to make it easier to see the oil level in them, but it seemed to make it harder

Refinishing an 89 superliner

I think Mechohaulic is on the right path here. I believe it is a "Variable Resistance Ground" system. The better the Ground, the higher the gauge reads. I am assuming the truck has a separate gauge that is not part of a instrument panel with a circuit board. I am not familiar with Superliners. Would love to have one someday though. I had similar problems on my "93 CH613. This is what I did to troubleshoot the system. It sounds like you did a continuity test on the wiring from the gauge to the sending unit. If you have "0" Ohms resistance, the wiring is good. The gauge likely has three pins on it. Power, Ground, and Signal. The Signal pin would be the wire returning from the sending unit. To test the gauge, remove the gauge from the dash and connect 12v to the Power pin and ground to the Ground pin. Then momentarily jumper the Signal pin to the Ground pin and the gauge should read Full. If not, you likely have a bad gauge. To test the gauge and wiring, reconnect the gauge and disconnect the plug from the sending unit and momentarily connect a jumper across the two pins, the gauge should read full. This means the wiring and gauge is good. To test the sending unit, reconnect the plug and physically move the float up and down, the gauge should respond accordingly. I removed the sending unit from the tank, it was easier for me to work on it. If all of those check out and it doesn't read correctly, I suspect there may be a mismatch between the sending unit and the gauge. My fuel gauge only reads to 5/8 full on a full tank. Sending unit from Mack and Fuel Gauge from PAI. I suspect there is a mismatch or calibration issue going on. I was lucky enough to get a complete wiring diagram from my local Mack dealer, it was very useful in tracking all of this down in the truck. Hope this helps and Good Luck. The truck looks awesome!! - Yesterday

Mixer mounted up, need to tighten mounting bolts and hook electrical plugs, hydraulic pump, water tank rebuild the mixing auger for the back... (worn from use, not collision) I'm also chasing an ABS code that is bugging me. Right steer abs cable ripped so I put a new sensor in, but still have a code. Gotta get this truck ready for inspection!

Refinishing an 89 superliner
Joey Mack replied to tegra1027's topic in Antique and Classic Mack Trucks General Discussion
highly possible. I think there is even one that is just a straight stick with a sensor in the stick.. I prefer the ones with the arm and potetchiometer... Sorry about my spelling.. -
Yup cumbys coffee. I was going to weld d rings to the bucket but I saw this on the Vevor website, d rings, grab hooks and a 2" receiver 4 bolts and done.

I think I have at least 3 different style sending units on my fleet. -
Was a qualified fireboat pilot when I was at the Philadelphia Naval Shipyard Fire Dept- we had a saying: If you don't have power to the screws and rudder, you can't argue with the tide, current and the wind!
-
This terrible news for all, I don't know anything about ships, boats, tug boats floating in a inner tube etc I do imagine that once you loose power the current takes control and pushes you about however mother nature wishes the current to flow Easter is going to be very different and a sad occasion for a lot of families now The whole situation is terrible Paul

FWD Thx for the radio info. Explains it all. I saw another clip that said they declared a Mayday with just 90 seconds before impact so quick action on PD in stopping traffic when they did was huge-no cars went in water just the poor souls working. Had this been a DOT crew they probably would have had radio contact but contractor crew-doubtful.
-
Joey, does that mean you’re ready for the short bus it’s a horrible mess but every news clip I see they do not bring up that construction crew at all. I don’t know what’s up with that. Maybe you fellas heard something about them. I’m sure they’re all gone drowned That just sucks big balls to get it while you’re working… bob

Can a ships controls especially steering be controlled remotely? Why would they program something like that in? Unless it was a case like mutiny on board the ship I don't see how it could be a terror attack. Interestingly this isn't the first time this ship has struck something, unless that's more common for ships than I realized: https://en.wikipedia.org/wiki/MV_Dali

not sure what happened. I am off today as well. I’ll take it. Finish up what I started yesterday… yaaaaaaaaaaaaahoooooooooo

Just saw a video he just posted four hrs ago. He was headed for Baltimore before the bridge fell. Now they are at anchor waiting ten miles away from the bridge. .....Hippy
