14.
Rotate the capscrews evenly and progressively in rota-
tion to 9 ft. lbs. (12.2 Nm).
15.
Remove the cylinder rod from the holding fixture.
16.
Place T-seal and wear rings in the outer piston diameter
groove. (A tube, with I.D. slightly larger than the O.D. of
the piston is recommended to install the solid seal).
17.
Position the cylinder barrel in a suitable holding fixture.
EXTREME CARE SHOULD BE TAKEN WHEN INSTALLING THE CYLINDER ROD,
HEAD, AND PISTON. AVOID PULLING THE ROD OFF-CENTER, WHICH COULD
CAUSE DAMAGE TO THE PISTON AND CYLINDER BARREL SURFACES.
18.
With barrel clamped securely, and while adequately sup-
porting the rod, insert the piston end into the barrel cyl-
inder. Ensure that the piston loading T-seal and wear
rings are not damaged or dislodged.
19.
Continue pushing the rod into the barrel until the cylin-
der head gland can be inserted into the barrel cylinder.
20.
Apply JLG Threadlocker (P/N 0100011) to the socket
head bolts and secure the cylinder head gland using the
washer ring and bolts. Torque bolts to 35 ft. lbs.
(47.5 Nm).
21.
After the cylinder has been reassembled, the rod should
be pushed all the way in (fully retracted) prior to the
reinstallation of any holding valve or valves.
22.
Install the valve assembly. Torque capscrew to 114 in.
lbs. (13 Nm).
