Tuning lower shock absorber closure.

The standard lower shock absorber closure of BWS and LOSI 5T models are equipped with various O-rings and bushings which often leads to wear and leakage.

This set is equipped with an extra long supporting POM guide bush in combination with an oil seal. This ensures a very smooth damper that does not leak anymore. Can be easily fitted in the excisting cap and shock housing addition.

Fill and Bleed:

• 1)   Remove the oil when necessary
• 2)   Fill the damper up to 10 mm below the rim with new oil
• 3)   Now gently push the rod upwards to just below the oil level
• 4)   Now gently pull the rod back down
• 5)   Now let the damper stand upright for 5-15 minutes so that the air bubbles can come out, (the time depends on the oil thickness)
• 6)   Repeat steps 4 and 5 until there are no more air bubbles in the oil.
• 7)   Now push the rod halfway up the damper
• 8)   Now gently press the red cap without O-ring on so that the excess oil can come out
• 9)   Remove the cap, fit the O-ring and push the cap into the body as far as it will go
• 10) Now screw the cap on.
• 11) The bound and rebound can be set by the amount of oil.

During assembly, we recommend lubricating the guide bushing and oil seal with a little silicone oil.
