Mid Boom Lift Cylinder Removal
NOTE:
The Upright weighs approximately 92 lbs. (42kg) and Main
Boom weighs approximately 450lbs. (204kg).
1.
Place machine on flat and level surface. Place the Main
Boom in a horizontal position. Place the Mid Boom in a
10 degree elevated position. Support Main Boom with a
prop. Support upright with suitable lifting device.
NOTE:
The Mid Lift Cylinder weighs approximately 60 lbs. (27.2
kg).
2.
Using slings, restrain the lower lift cylinder.
3.
Remove the hardware securing the cylinder rod attach
pin #3 to the boom. Using an appropriate brass drift,
drive out the cylinder rod attach pin #3.
4.
Tag and disconnect hydraulic lines from the main lift cyl-
inder. Use suitable container to collect any residual
hydraulic fluid. Cap hydraulic lines and ports.
5.
Remove the hardware securing the barrel end attach pin
#4 to the boom. Using an appropriate brass drift, drive
out the cylinder barrel pin #4.
6.
Remove the lifting device from the mid lift cylinder.
7.
Carefully remove cylinder from boom. Place in a suitable
work area.
Mid Boom Lift Cylinder Installation
NOTE:
Coat I.D. of bushings with specified lubricant prior to
installing pins.
NOTE:
The Mid Lift Cylinder weighs approximately 60 lbs. (27.2
kg).
1.
With the booms positioned and supported, place cylin-
der in position and secure in place using slings.
2.
Install the cylinder barrel pin #4, being sure to align the
hole in the cylinder barrel pin with the retaining pin
screw hole. When holes align, install hardware.
3.
Correctly install hydraulic lines to cylinder as previously
tagged. Extend cylinder rod slowly until attach pin hole
aligns with those in boom.
4.
Using a suitable brass drift, drive the cylinder rod attach
pin #3 through the aligned holes. Secure the pin in place
using retaining hardware.
5.
Remove boom prop and suitable lifting device.
6.
Take the lift cylinder through one complete cycle to
assure correct functioning. Place boom in stowed posi-
tion. Check hydraulic fluid and adjust accordingly.
