How to Disassemble the Scissor 

Assembly 

 

Bodily injury hazard. This 

procedure requires specific repair 

skills, lifting equipment and a 

suitable workshop. Attempting 

this procedure without these 

skills and tools could result in 

death or serious injury and 

significant component damage. 

Dealer service is strongly 

recommended. 

Note: When removing a hose assembly or fitting, 

the O-ring (if equipped) on the fitting and/or hose 

end must be replaced. All connections must be 

torqued to specification during installation. Refer to 

Specifications, 

Hydraulic Hose and Fitting Torque 

Specifications.

 

1  Remove the platform. Refer to Repair 

Procedure, 

How to Remove the Platform.

 

2  Remove the cables from the platform 

centering link (index #1) at the hydraulic tank 

side of the machine. 

3  Remove the cables from the number 4 inner 

arm (index #14) and lay the cables off to the 

side. 

 

Component damage hazard. 

Cables can be damaged if they 

are kinked or pinched. 

4  Secure both ends of the number 4 inner and 

outer arms (index #14 and #2) together with a 

strap or other suitable device. 

5  Attach a lifting strap from an overhead crane 

to the number 4 inner and outer arms (index 

#14 and #2) at the steer end of the machine. 

Do not apply any lifting pressure. 

 

6  Attach a lifting strap from an overhead crane 

to the number 4 inner and outer arms (index 

#14 and #2) at the non-steer end of the 

machine. Do not apply any lifting pressure. 

7  Remove the pin retaining fasteners from both 

number 4 pivot pins (index #4) at the non-

steer end of the machine. Do not remove the 

pins. 

8  Remove the pin retaining fasteners from both 

number 4 pivot pins (index #15) at the steer 

end of the machine. Do not remove the pins. 

9  Use a slide hammer to remove both number 

4 pivot pins (index #4) from the non-steer end 

of the machine. 

10  Use a slide hammer to remove both number 

4 pivot pins (index #15) from the steer end of 

the machine. 

11  Carefully remove the number 4 inner and 

outer arms (index #14 and #2) from the 

machine. 

 

Crushing hazard. The number 

4 inner and outer arms could 

become unbalanced and fall 

when they are removed from the 

machine if not properly 

supported by the overhead 

crane. 

Note: If further disassembly of the scissor arm pair 

is required, refer to Repair Procedure, 

How to 

Disassemble a Scissor Arm Pair.

 

12  Remove the pin retaining fasteners from the 

lift cylinder rod-end pivot pin (index #17). Do 

not remove the pin. 

13  Attach a lifting strap from an overhead crane 

to the lifting eye at the rod end of the lift 

cylinder.
