4.

Press the end cap into the reservoir to access the 
snap ring.

5.

Remove the snap ring, then remove the cap from the 
body.

6.

Place the shock lower eyelet in a vise.

7.

Loosen and remove the bearing cap from the shock.

8.

Remove the used oil from the shock body.

NOTE:  Insert the IFP tool (PN PS-45908) and cycle the 
internal floating piston (IFP) a few times to purge the 
shock oil from the reservoir.

9.

Remove the IFP from the reservoir with the IFP tool 
(PN PS-45908).

10. Clean and inspect ALL parts and replace worn out 

parts if needed.

IMPORTANT: Seal kits are available and should be 
installed at this time if seals or o-rings are damaged or 
worn.

11. Place the shock rod in a vise so that the threaded part 

is facing upward.

12. Place the valve stack on a clean shop towel in order 

of removal.

NOTE:  Place the valve stack on a clean shop towel in 
case you have to move them. This will also help when 
assembling them back onto the shock rod.

13. Inspect the valves for kinks, waves, pits or foreign 

material.

14. Inspect the piston wear band and replace if damaged 

or worn.

Walker Evans Remote Reservoir / Piggyback 

Shock Assembly

1.

Secure the shock rod in a vise with the threads of the 
rod facing up.

2.

Place the compression valve stack on the rod in the 
reverse order of disassembly.

3.

Place the valve piston on top of the compression 
stack.

4.

Place a new lock nut onto the shock rod. Torque the 
new lock nut to specification.

IMPORTANT: Do not over torque or damage to the 
valve stack can occur.

5.

Secure the shock body by its lower mount.

6.

Set the compression damping adjustment selector to 
position “1”.

7.

Fill the shock body and remote reservoir 1/2 full of 
Walker Evans 5w shock oil (PN 2874522).

8.

Apply a thin film of oil to the IFP o-ring and floating 
wear band located on the shock rod piston.

9.

Compress the wear band and insert the IFP into the 
reservoir. Allow as much air as possible to escape as 
you install the piston.

10. Screw the IFP tool, PN PS-45908, into the IFP.

11. Hold or place the reservoir as low as possible on 

remote reservoir shocks so the air will travel upward 
as you slowly cycle the IFP up and down.

• Be sure to bottom out the piston in the reservoir 

body.

• Allow time for the bubbles to dissipate.

• Repeat the process until all the air has been 

removed.

CAUTION

SHOCK CONTENTS UNDER HIGH PRESSURE. 

ALWAYS WEAR SAFETY GLASSES WHEN 

WORKING WITH SHOCKS.
