• J-shaped seal body and O-ring against U-shaped seal body.
The open side of the J-seal should face outboard (toward
the sealing head).
7. Inspect the HP cylinder threads and apply High Purity Goop to the
threads and shoulder guides, then screw the HP cylinder into the
hydraulic cylinder head. Note that shoulder guides are close-
fitting smooth diameters located at either end of cylinder threads.
Be sure to support the weight of the HP cylinder. As the HP
plunger seal goes into the cylinder, the cylinder will become
difficult to rotate. Use the special cylinder wrench to assist, as
necessary.
8. Tighten the HP cylinder hand tight with the cylinder wrench, then
tap the cylinder wrench with the hand’s palm to tighten.
9. Install bore liner into HP cylinder. The sealing head can now be
installed onto the HP cylinder (Section 7.2.2).
