    1992 E7 400 Shutdown Light comes on

    I think it is the high coolant temp sensor. It only comes on when I am pulling heavy and hard and the temp works it way towards 200. I watched it yesterday and when it was just above 195 degree mark the light came on. It stays on even after the temp settles back down. My jake quit working again so I am going to pull the valve covers today and check the valves myself and the jake wires. I am glad I spent so much money at Westfall Mack in Kansas City to get this issue fixed. I check my miles less than 1200 and since they put there hands on it been one thing after another.

    Numerous rebuilt Mack trans and diffs for sale cheap

    I called about a set of rears must pick up I was going to buy all the crd 92/93 but they didn't want to ship
  4. Been working " Big Ugly " a lot and had it in to the Mack dealer as they were doing overhead specials for$475. While it was there I had them check the "jake" as it was starting to cut out and do a service. With in 700 miles of having it in I had started losing power and EGT went up to about 1000. I pressure tested system found leak at the air compressor inlet separator/filter valve. Got that fixed and installed a boost gauge. Hard pull 90 to 100K I am getting 30 psi boost egt is 900 to 950 no smoke, temp gauge shows about 190. If I let up and baby it egt about 850 to 900 boost about the same temp stays around 185. Oil pressure around 60psi both ways hard or babying. If I baby it the shut down light does not come on, if I pull hard it will. the lighting bolt does not come on, truck does not lose power, does not shut off. If i turn truck off it will reset. I have checked coolant as Superdog thought they may be the issue, I checked wiring to the sensors and unplugged the pin plug on the pump and checked the wires all seem good same with the ecovance. What other sensors would make the light come on without shutting the truck off or throwing a code?

    Should be a heat shield then the hard copper heater lines on top. The studs secure the shield and clamps that hold the hard lines.

    CRD 93 Housing w/or w/o transverse rod

    That's the one. On mine only the rear crd93 has the transverse rod. We're those on air ride? My 85 on neway has the rods on both rears

    CRD 93 Housing w/or w/o transverse rod

    The parts truck with old style housings are 4.64 I have 4.42 now that one is bad for sure, the other the breather was missing and it was full of dirt so
  13. On my new acquisition R it has the bracket with transverse rod that on the rear carrier mounts to the frame and uses the dog bone style torque rod that mounts to the cross member. I have found a set of 4.64s but they are without the holes for the mounting bracket for the transverse rod and it uses the old style torque rod. I have been looking for a new style cut off but in my area slim pickings, or the ratios are to high or low. I have checked on rebuilding or remans but cant justify the costs yet. Has anyone drilled the housings and used bolts for the bracket? I don't want to run the old style as I would probably make it the rears feel loose with a 16ft box grossing 80k.

    Are Mack transmission side mount PTOs interchangeable or do they fit only specific transmissions?
