  1. nothing is rusty, it looks ok, no twists or bends, not sure why it will not go on properly, am planning to pull it apart again, remove the clutch disk and then try it on the trans splines just to be sure.
  2. I think I found the problem, the clutch disk is not quite on the splines correctly and is binding up, its pushed by the splines and is opening the pressure plate causing them to disengage, not sure how that is possible when the transmission and bell housing went together fine. I am not sure if perhaps there is a burr on the spine or not or why it did not slide on correctly. I am now having difficulty getting it loose enough to put it on the splines correctly. I have loosened off the transmission and still no go, these parts are extremely heavy and not easy to "jiggle" them into place. I am going to try and loosen off the pressure plate and try to move the disk around through the grease fitting plate on the bottom. If that does not work, then the motor will have to come out again and the clutch will have to be centered again. Any ideas on any easier ways?
  3. the motor is not running yet I had just installed it. the transmission shifts fine however when you put it in gear and manually turn the engine over with a socket wrench the trans binds up and you cannot get it out of gear, if the truck is rocked it pops out. I do not think the trans is the issue its in between the clutch and that it is already engaged somehow. My guess is that somehow the throwout bearing is binding up and has disengaged the clutch already when the engine and trans went together. upon doing this there is no contact between the pressure plate and clutch thus allowing the engine to turn freely with the trans in gear and again why there is no clutch pedal. I have planned to use longer bolts on the bellhousing to allow me to seperate the engine and trans and see if i can free up the clutch or throwout bearing and then regain the proper clutch clearance. i just really do not want to pull the engine out again and really just wanted to know if the input shafts on mack 5-2 and mack 5-3 are the same or are bigger.
  4. I recently installed a en401 in my b42, it has a 5-2 duplex. the engine went together with the transmission incredible well. it bolted together with no problem. however now there is no clutch pedal at all, you can push the clutch pedal and it does nothing, if you turn the engine over with the trans in gear the engine turns over freely and the truck does not move. I am stumped as the engine and the trans bolted together with no trouble and it appeared the splines slid together easily. I am thinking perhaps the spline on the 5-2 was smaller than the clutch disk and is now just spinning inside. are all the splines on these transmissions the same? is there something i may have missed? I hate to pull it apart again. any suggestions?
  5. 1948 white super power mustang has the exact same fenders and some interior as the old macks

  8. I have two EN401's and both are factory painted gold. Long but burned off though.
  9. I have a 65 mack B42 dump that came with a EN402 with a oil cooler unit on the block and a carb govenor. I have another 59 mack B42 tractor that came with a EN401 with a carb govenor but no oil cooler. I am replacing the engine in the 65 dump with another engine I aquired and was out of a water truck. It is a EN401 and has no factory governor, or oil cooler. Question is, how important is it to put the governor and oil cooler back on the engine I am replacing in the dump truck? I don't plan on working it hard and just using it now and again, it also does not get overly hot in this climate. I did some checking and it appears the oil cooler was an option on these engines for certain applications, however not sure why all the engines did not come with a govenor. I am not overly familiar with these old gas engines, I don't want to blow it up for lack of knowledge. Any input?
  10. I may have a mack for you if interested, where are you located in Canada?
