  1. Well I ordered new compressor new dryer nee expansion valve took evaporator core out had it pressure checked and clean no holes .. Reinstall everything including orings ac goes down to 34 degrees now .. Plan to do the same with my other 2 rds
  2. Driver said light came on then they stopped never went above 200 driver said but we know how that goes..it doesn't get hot now but light comes on and if you don't add water truck shuts down by computer. Running 71000 bout 8 10 hr day use bout half gallon 2 to 3 days .you can see where it pushes out on the frame tanks have more then normal water
  3. No it doesn't pull back in the top tank .it just push it out the small hole in the bottom tank cap and that's it ..I replaced the cap on both tanks at the same time I did thramastat but I could have got a bad cap.
  4. Getting water in air tank is this the compressor head gasket going out
  5. Replace the stat cause it went bad now the truck push water out the little hole in the holding tank. What would cause this truck doesn't run hot just lighting volt come on bout 3 days add water bout 3 days later light on depending on how hard the truck is worked. Quad axle dump truck
  6. Which do you guys think is better red dot back wall mount or replacement stock system..gotta get this thing going
  7. 2000 rd688 driver side air bag has a pin hole in it so I need to replace it..I took the air line off got the bottom out but cant get the top to come out does it bolt in or something..my freightliner bag looks the same and just pop in a hole Thanks for any help

  10. Ok guys update truck has been fixed Turns out the pin in the spring pak on driver side was broken and the u joints on the top of gear box and inside can was worn out no splines left inside them Replace and truck is back working like a dog lol Thanks guys
  11. Yes turning on the shaft about half inch I didn't know that the yoke that goes on the shaft had splines so maybe the splines are worn I going to try and remove the yoke from the top of the shaft and see what things look like But I know if I have the truck up on the jack with no pressure on the steering it turns free no binding or locking Mack dealer said could come from pot holes on the job binding the u joint set up beyond its travel and wild driver trying to fly on job site which I know they do I've gotten on them before for the same reason I'll try to get a picture of the problem thanks
  12. No it hasn't been off I'm thinking that the rough job has beat it up and caused it to slip more then it should move on the gear box shaft..cause driving it some times it doesn't even get to that point where it has that little bite of lock
  13. I'm thinking that my u joint at the box is bad because I have a spot now that locks them let's go and makes a loud pop.if I look at the box and joint with someone moving the wheel back and 4the joint slips around the top of the shaft about a half inch ..anybody have this problem before. Been on a rough haul dump truck in sand pot holes wild driver with lead foot.im hoping it's not the box Oh 2000 rd690 E7 auto Thanks for the help
