COLLECTOR SEAL REPLACEMENT
(For Collector 553-02044)
See Figure 3.
Find a clean work area to perform this procedure.
1. Remove retaining plate cap screws, retaining plate, dust shield o-ring and nylon thrust washer. Separate the
spool and housing by pressing or gently tapping with a plastic mallet and remove wear rings.
2. Clean and inspect the housing bore for any physical signs of damage. NOTE: Polished witness marks from the
seals will be visible, but present no problem unless they show excessive wear.
3. Placing the spool upright on the work surface, remove all of the seals and back-up o-rings by pushing a small flat
head screw driver through the seal and o-rings, being careful not to scratch any part of the seal groove.
4. Remove the lower nylon thrust washer and lower o-ring. Clean and inspect the spool for any physical damage.
