REPAIR INSTRUCTIONS

14.Slide the piston into the tool until it bottoms on the flat surface.

Do not over-stretch the Teflon® seal. Be sure that the seal lips seat over each side of the O-ring.

12.Install the wiper ring into the upper (thin) piston groove.

13.Place the range shift piston seal sizer/piston installer (tool No. J 47359) flange-side (pilot end) down on a clean flat surface.

It is recommended that the piston assembly be allowed to remain in the seal sizer/piston installer tool for approximately 15 minutes before proceeding with the final assembly. This will properly size the O-ring and seal to the piston, and make final installation easier.

15.Using a piece of crocus cloth, polish the end of the shift rail and around the setscrew hole to remove any sharp edges or burrs. This will prevent damaging the seal as the piston assembly is installed into the cylinder. Be sure to clean any debris from the shift rail after polishing with the crocus cloth.

16.Remove the piston assembly from the seal sizer/piston installer tool.

17.Carefully clamp the range shift cylinder assembly in a vise. DO NOT remove the range shift cylinder Teflon® seal installer/sizer from the cylinder assembly. The tool will be pushed from the shift rail bore as the piston assembly is being installed. Place the range shift piston seal sizer/piston installer with the flanged-side (pilot end) on the cylinder housing.

18.Align the shift fork locking bolt hole in the shift rail with the air line fitting port in the cylinder housing.
