NOTE: Before rebuilding or revalving your QA1 shock absorbers, your work area must be clean.  
Shock absorber performance is greatly affected by any contamination (i.e. dirt, dust, rag lint, etc). 

TOOLS NEEDED FOR REBUILDING AND REVALVING 

Vise with soft jaws (aluminum or plastic)

Spanner wrench (Available from QA1)

Torque wrench with 1/2” socket

3/8” wrench or socket

Pick set

QA1 Shock oil (Part number SF04)

Rebuild kit and/or revalving kit

DISASSEMBLY 

1.

Check shock mount bearings for excessive play, replace as needed.

2.

Clamp shock body eyelet in a vise, with shaft pointing up.

3.

Fully extend shock rod from body.

4.

Using a spanner wrench, unscrew the shock closure nut.  (Shock is not pressurized!)

5.

Use a pick tool to remove closure nut o-ring.

6.

Remove shock rod assembly, gland, and compression (inner) tube by
pulling up on shock rod.

7.

Remove gas bag from shock and set aside in area where it will not collect debris.

8.

Pour oil from shock body and compression tube, watch for any debris in the used oil.

9.

The base valve can be left in the compression tube and disassembled from the outside.
Use a 3/8” wrench or socket to remove the disk retaining nut. The bolt is threaded into
the base valve body from the inside so it will be retained. The internal disk and spring
need not be removed.

10.

Clean the parts with mild solvent as necessary and set aside.

11.

Clamp piston-rod eyelet in a vise with the piston pointing up.

12.

Remove ½” lock nut to access piston valving. Remove piston and valving.

13.

If not revalving, the rebound stack, piston, and compression stack need to be kept in its
original order for re-assembly.

14.

Remove the gland assembly, and piston-rod seal from the rod.
