Longer mold life can be achieved by following a few basic rules. Be sure to clean all parts and mating surfaces thoroughly before assembly. Always be sure parts are properly aligned and use proper torque requirements. To assure that parts are square, start with a good working surface such as a Besser portable mold jig. A visual inspection is suggested to make sure parts are not burred or scored. NOTE: Always start with new lock washers and only use a brass hammer.

1. Outside division plates should be torqued to 625 - 675 ft. lbs. (930 - 1005 newton-meters). Outside division plates with cutouts for face liners should be torqued to 175 - 195 ft. lbs. (260 - 290 newton-meters).
   
2. Due to the differing grades of vibrator bolts and vibration systems, please consult factory.
   
3. Core bars should first be snugged initially front and back.
   
4. Then core bars should be torqued to 70 - 90 ft. lbs. (105 - 135 newton-meters). Align front and back as uniform as possible to the mold side bars. Check cores for center between division plates to assure uniform block dimensions. (A wire can be secured through the hold down bolt heads as a safety to prevent the bolts from coming loose during constant vibration.)
   
5. Secure plungers to stripper head plate - 100 - 140 ft. lbs. (150 - 210 newton-meters).
   
6. Align the stripper shoes.
   
7. Threaded inside division plates should be torqued to 40 - 50 ft. lbs. (60 -70 newton-meters). Tanged inside division plates should be torqued to 100 - 120 ft. lbs. (150 - 180 newton-meters).
   
8. End liners should be torqued to 100 - 140 ft. lbs. (150 - 210 newton-meters).
   
9. Stripper shoes should be torqued to 65 - 75 ft. lbs. (100 - 110 newton-meters).
   
10. Center Posapac Vibrator Weights as close as possible to assure uniform vibration and that the nuts face the outside of the mold.
