    1982 Mack R700
  1. This is the information I received from my dealer
  2. If anyone has available the frame ratings on a CL700 frame? Or a build sheet etc that would be most helpful. Thanks
  3. I have a 1996 Mack E7-454 that I would like to upgrade to the air clutch fan. I'm looking for any help with wiring in the factory engine harness, factory install location for the air solenoid switch. I realize I could get a temp switch and high pressure a/c switch and run it that way. Thanks
  4. When we built our triple frame wrecker chassis we drilled the outer and inner frame rails and tapped it for grease fittings about every 12" or so depending on the location of brackets, suspension hangers, etc.. It has been on the road for 5 years with zero rust build up that we can see between the frame. Once a year we push fresh grease through the rails. On our recent rollback build, out of a 79 R model, I split the rails one side at a time while supporting the cab and engine/ trans. Used Eastwood rust convertor and rust encapsulator then top coated with a good high solids paint. I drilled the outer rails for grease fittings as well. It works great for us.
  5. You can clear up a lot of the rust between the rails by using an air hammer. You'll be surprised how much rust will come out between the rails. Get some good ear and eye protection and have at it.
  6. Actually Henrickson has a very good tech department. I would give them a call and find out what axle brackets you will need part # wise and see if they are already on the suspension. The tracking rod mounting might be another problem, but they should be able to help with that as well.
  7. They frequently build and sell wreckers after a few years of service.
  8. We just went through this with our 454 a little while back. There is some service bulletins from Mack that discuss this. Here are some pointers to start with. The screen at the back of the oil cooler can be clogged up with debris, the water pump seal goes bad and can suck air and cause a coolant pushing condition. The radiator cap can be bad. The air compressor head could be cracked and putting air into the coolant system. Then finally the more expensive problem...cracked heads or blown gaskets. I would first try a new radiator cap if that stops it you got off very cheap. To check if the compressor is putting air into the coolant you can bypass the cooling lines at the compressor and see if it still pushes coolant. CAUTION do not let your engine run too long or the compressor can overheat. The water pump test is just as easy to replace the water pump in my opinion and while you are at it pull the oil cooler, the back end has a screen which might need to be cleaned out. Also a thermostat would be a good thing to do as well. Not a very difficult job. Now if none of these fix your problem you want to check for exhaust gases in the coolant. First remove the fan belts so the water pump can't rotate, remove the thermostat and re-install the housing minus the thermostat, fill the coolant until it is almost to the top of the thermostat housing with the hose removed. Start the engine and look for bubbles or puffing similar to a model train. If there is any evidence of this you will need to start pulling heads. Either a gasket problem or a head cracked between the valves. Hope this helps We weren't so lucky it was a cracked head at #2 cylinder
  9. I wouldn't be jumping head over heels just yet if they are similar to the I shift. They are very expensive to replace. The truck can not be moved if the engine is not running. If by chance your truck were to shut off in traffic it couldn't be dragged to the shoulder without disconnecting the drive shaft or pulling all four axles first. Otherwise the trans gets ruined. Just what we have been told as towers.

  12. There are some aluminum air tanks listed on ebay in commercial truck parts. I think they were Pete tanks, but they were the type that mount perpendicular to the frame. I think it was Frontier truck parts.
  13. An Eaton/Fuller 9 speed can be changed to a 18 speed or 13 speed with an upgrade kit that is available through Fuller. Got look on their website for the part number.
