1997-2001 Honda CR250 Rear Shock Shaft Assembly

  • Step 10: Place the seal bullet over the end of the shock shaft. This will protect the threads and create a smooth surface for the seal head to slide over.
  • Step 11: Install the collar, bumper, shock body cap, and seal head.
  • Step 12: Install the valve stack. Slide the shims and valve around until they line up; do not force them!
    • *Do not install the valve bushing yet. The valve bushing creates a seal around the valve, but when filling the rear shock body with oil, the oil needs to flow around the valve to get as much air out as possible. We will install the valve bushing right before the final assembly.
  • Step 13: Apply a generous amount of thread locker to the shaft threads.
  • Step 14: Thread and torque the shaft nut to 35 to 50 foot-pounds
    • Wipe off any excess thread locker. You don’t want it flaking off and clogging up your rear shock.
  • Step 15: After you torque the shaft nut, use a punch and hammer to seal the threads.
