Before and after every test, carefully examine the o-ring on the cell cap. Re-
place it if it shows signs of damage or wear. This procedure only applies to
the Model 2025 Consistometer (#120-35).
1. Unscrew the cell cap and raise it above the cell.
2. Remove the retaining ring from around the bottom of the cell cap. The
o-ring and backup ring should fall off easily.
3. Apply high-temperature grease to the cell cap where the backup ring will
sit. Also apply grease to the o-ring.
4. Place the backup ring (#120-35-004) onto the cell cap with the narrow
side pointing up towards the threads.
5. Place the new o-ring (#120-149) onto the cell cap beneath the backup
ring.
6. Place the retaining ring around the bottom of the cell cap so that it holds
the o-ring and backup ring in place.
7. Apply anti-seize compound to the cell cap threads.
