New direct drive gear box install for Gloucester series 200 extruder 24:1 4.5 " 200hp water cooled; we had a hard time removing the old gear box due to no head room so we had to use small air bags to lift box and roll it back enough to lift on to the fork truck. Always return old gear box for the core charge as it is usually very expensive. Gloucester makes it fairly easy in install new boxes as long as you remember to bore scope the barrel and line up the new box to the old barrel. You should never be more than .003 thousands out of alignment the entire length of the barrel. Make sure you install the heat exchanger with 5 micron water filters before the box with bypass so you can change out new ones. Use only the recommended oils for the new gear box due to the fact that the wrong oil will knock out the new seals right away.
