TM10-3930-660-34 16-9.  FRAME TILT CYLINDER - REPAIR (Cont’d) ASSEMBLY NOTE Wipe   all   sealing   surfaces   on   cylinder clean    and    dry.    Apply    film    of    clean hydraulic   oil   to   all   seals   as   they   are installed. 1.ASSEMBLE CYLINDER PARTS (1-19). a. Install  seal  (18)  and  rod  wiper  (19)  inside  gland (9).Ensure   that   seal   (18)   lip   is   positioned   the same way as it was before disassembly. b. Install back-up ring (17) and new O-ring (11) on outside diameter of gland (9). c. Slide gland (9) onto rod (8). d. Lubricate  piston  (15)  inner  diameter  with  clean hydraulic oil.  Install new O-ring (16) inside bore of piston (15). e. Use a cleaning solvent and lint free rag to clean threads on rod (8) and new nut (14). f. Slide piston (15) onto rod (8). g.   Apply   Loctite   #271   on   threads   of   rod   (8)   and   nut (14).Install nut  (14) on rod (8). h.    Place    rod    (8)    and    piston    assembly    on    suitable supports to prevent damage during assembly. i. Install   two   wear   rings   (12)   and   one   new   seal (13).Position  wear  rings  so  that  gaps  are  180 degrees apart. CAUTION Use   care   when   installing   rod   (8)   and piston  assembly.    Keep  rod  (8)  in  line with cylinder tube (10) to prevent binding.  Failure to follow this precaution will cause part damage. j. Lubricate    cylinder    tube    (10)    inner    diameter, piston    (15)    outside    diameter    and    gland    (9) outside diameter wiht clean hydraulic oil. k. Position  rod  (8)  and  piston  assembly  in  cylinder tube (10). NOTE Tighten  gland  (9)  so  that  it  is  flush  with end  of  cylinder  tube  (10).Do  not  over- tighten gland (9). 1. Tighten gland (9) onto cylinder tube (10). m.    Install back-up rings (2 and 3), two back-up rings (4)    and    three    new    O-rings    (5-7)    on    each counterbalance valve (1). n.
