14.Apply grease to anti-extrusion block and put in recess of seal assembly, with ground face showing.

15.Apply grease to seal assembly and put in body counterbore. Anti-extrusion block must face body on the tank port side when the motor is assembled (same side as bridging insert).

16.Mating surfaces of body and cover must be clean, free of oil and dry. Clean both surfaces with “Locquick” primer or clean shop solvent. Spread a thin, even coat- ing of “Loctite 515 Gasket Eliminator” or equivalent on one surface.

17.Assemble the body to the cover, making sure that none of the parts become displaced. Insert the cap- screws and washers and hand tighten.

18.Before tightening the capscrews, rotate the drive shaft in the direction of normal rotation (counterclock- wise) to check for binding. You may not be able to rotate the drive shaft by hand. Protect the shaft if using a pliers.

19.Tighten the capscrews evenly in a crossing pattern to a torque of 190-210 in-lb.

20.Carefully install a new spacer, shaft seal and snap ring. (Perform steps 8 - 12 under Reel Motor Shaft Seal Replacement in this section of the book).

21.Allow 60 minutes for liquid gasket material to harden before operating motor.
