2 Two Component Meter Cylinder Assembly Replacement Installing the Packing Gland and the Plunger. Make sure the inside of the cylinder assembly is clean and free of any material before installing the new packing gland assembly. CAUTION: Do not use petroleum-based lubricants. O-rings and seals could be damaged. 2. Apply synthetic oil to all parts, packing gland O-rings, and seals before assembly. CAUTION: Do not pinch or crimp O-rings during assembly. O-rings could be damaged. 3. Apply thread-locking compound to the new packing gland assembly thread. Thread the packing gland assembly into the cylinder assembly. 4. Use a spanner wrench to tighten the packing gland assembly to 54 N m ( 40 lb-ft). CAUTION: Do not damage the seals, when inserting the new plunger. 5. Insert the new plunger, tapered-end first, into the new packing gland assembly. 2000 Nordson Corporation
