3. Install the snap ring on the piston bar, using care to avoid overstretching the snap ring.

4. Apply Eaton®Fuller® silicone lubricant #71206 or equivalent to the range piston lip surface and to the four (4) Orings.

5. Install the proper O-ring in the groove in the range cylinder.

6. Install the range piston assembly in the range cylinder.

7. Install the proper O-ring in the groove on the inside of the range cylinder cover, and install the largest O-ring in the groove on the outside of the range cylinder cover.

8. Place the smallest O-ring in the recess in the cover, and install the cover.

9. Apply Eaton®Fuller® thread sealant #71205 or equivalent to the retaining capscrews, and install the two (2) capscrews on the range cover. Tighten the capscrews to 20-23 lb. ft. (27-31 N•m) of torque. 8
