Step 9
Inspect and clean the end cap, torque tubes, cap screws, and springs. Replace if damaged.
Step 10

compress the nipple into the end cap. Lubricate the shoulder cap screws with Loctite and install. Release the
press.
Step 11
Clean and inspect the head, body, and wear plate. Replace if damaged.
Step 12 - Installation
Using a new gasket, reinstall the wear plate (8A) with cap screws (16A).
Tip: Pull the support tube out of the journal if it was pushed in during the previous step.
Step 13
Install the ring bracket with cap screws (20C).
Step 14
Clean the mating surfaces of the wear plate, new seal ring (6), and nipple. Attach the seal ring and end cap
assembly with four cap screws (3C).
Important: After fastening the end cap assembly, confirm the "X" dimnestion is correct. Refer to the Kadant
Johnson drawing.
Step 15
If there is an O-ring present on the support tube, remove it. Lubricate and install a new O-ring with silicone
lubricant. Apply anti-seize to the tapered portion of the tube.
Step 16
Install a new O-ring (26) into the body. Position the body over the support tube. Align the pin(s) with the support
tube indexing slots. Position both over the studs on the ring bracket and secure with hex nuts (20B).
Step 17
Apply anti-seize to the threads of the support tube nut. Insert two bent lock washer tabs into the body and install
support tube nut, torque to 300 ft-lbs (407 Nm). Bend two lock washer tabs over the bolt flats to prevent bolt
loosening.
