ASSEMBLY
INCORRECT SEAL INSTALLATION CAN CAUSE CYLINDER LEAKS AND IMPROPER
C YLINDER OPERATION. ENSURE ALL PISTON SEALS ARE CORREC TLY
INSTALLED. REFER TO CROSS SECTION ILLUSTRATIONS FOR CORRECT SEAL
ORIENTATION.
NOTE:
Use proper cylinder seal kit for cylinder assembly. See your
JLG Parts Manual.
NOTE:
Apply a light film of hydraulic oil to all components before
assembly.
1.
Install rod seal (13) and wiper seal (14) inside the cylin-
der head.
2.
Install o-rings (10 & 12) and seal (11) on cylinder head.
3.
Slide cylinder head assembly onto rod (2). Do not dis-
lodge or damage seals.
4.
Support rod in holding fixture.
5.
Carefully slide the spacer (15) onto the rod.
6.
Insert spring (5) onto the rod.
