14. Place the extend cable lug ends in the slots at the top of
the fly section and secure them with the keeper plate
and two capscrews and hardened washers.
15. Install a wear pad on the two upper telescope cylinder
wear pad holders using two flat head screws.
16. Position the wear pad holders on each side of the upper
telescope cylinder support foot and secure each with
two capscrews and washers.
17. Slide the upper telescope cylinder assembly part way in
(approximately ten feet). Place blocking under the rear
of the telescope cylinder to aid in assembly.
18. Using the cylinder mount shaft attach the lower cylinder
mount to the end of the lower cylinder. Attach cotter pins
to secure shaft.
19. Install the wear pad and skid pad with flathead screws to
the lower cylinder mount.
20. Lift lower telescope cylinder assembly and place on
upper telescope cylinder.
21. Install the wear pads with flathead screws to the top
plate cover.
22. Install the top plate cover assembly with four capscrews
and washers to the lower cylinder mount, to attach the
upper and lower cylinders together.
23. Install both ends of the retract cables to the appropriate
holes in the lower cylinder mount, making sure that the
cables are not crossed or twisted.
24. Install the adjusting bolts through the holes in the lower
mount shaft.
25. Install the sled assembly onto the adjusting bolts and
install both swivel nuts, making sure that the extension
cables are not crossed and twisted.
26. Secure each retract cable to the side of the upper
cylinder assembly near the trunnion with tape or ty-
wraps.
27. Slide the telescope cylinders into the fly section until the
trunnion on the upper cylinder is three feet from the back
of the fly.
28. Block up the telescope cylinders at the rear of the fly
section to aid in installing the fly section assembly into
the outer mid.
29. At the rear of the outer mid section, install the upper
wear pad grease line, connector and grease fitting on
each side.
NOTE: The grease lines are designed to be used only on
one side or the other (i.e. RH or LH).
30. Install the bottom rear wear pad on the outer mid section
with two capscrews and hardened washers.
31. Position the front end of the outer mid at the rear of the
fly/telescope cylinder assembly.
32. Place the mounting plates on the upper telescope
cylinder barrel mounting lugs.
33. Slide the fly/telescope cylinder assembly into the outer
mid section installing top rear wear pads in pockets of fly
section (cutout should align with grease line). Stop and
check rear wear pad clearance and shim if needed.
NOTE: Use shims as they are necessary to adjust wear
pads within 2 mm (0.078 in) of the outer mid
section side plate. Use equal number of shims on
side pads.
34. Continue to slide together being careful not to damage
cables.
35. Install bottom and side front wear pads in outer mid. Lift
up on the front of the fly section assembly and check
clearance between the pads and the pad box weldment
on the outer mid section. Install shims as necessary so
there is no more than 1 mm (0.03 in) clearance between
the wear pads and the fly section.
36. Install outer mid front top wear pads and shims as noted
during disassembly. Secure with four capscrews and
hardened washers each.
NOTE: Use shims as necessary to adjust wear pad so that
the wear pad is just touching or is within 2 mm
(0.078 in) of the fly section side plate at both the top
and side surfaces of the top radius.
37. Install bottom and side wear pad keeper plate on each
side of the outer mid and secure with eight capscrews
and washers each.
38. Install top wear pad keeper plate on each side of the
outer mid and secure with two capscrews and washers
each.
39. Continue to completely slide together.
40.
Lift up on end of the upper cylinder to align barrel
mounting plate holes with holes in outer mid. Secure
each with four capscrews and hardened washers.
41. Remove any blocking under the upper cylinder.
42. Detach the retract cables from the upper telescope
cylinder, place the cables around each retract sheave,
place the sheave onto the shaft weld and use four bolts
DANGER
Ensure the telescope cylinders are securely blocked and
some means used to hold them together to prevent any
accidental movement. Severe injury can occur if the
cylinders drop.
