HELM MKII Damper Side (Air & Coil) 100 Hour Service (Part 1 of 2)

Recommendations and Warnings

Cane Creek recommends only trained suspension technicians perform service on all suspension, using all required tools and following all proper procedures. Anyone without access to the proper equipment or with any concerns on the procedures should defer to an authorized Cane Creek service center for service. Improper service can result in loss of performance or suspension failure. All Cane Creek forks have pressurized oil. Follow the service procedures exactly as written to avoid possible injury or harm to the suspension. Always wear eye protection while performing suspension service. Please dispose of all waste products and materials through proper channels to avoid contamination of the environment.

Any damage or issues resulting from improper service will not be covered by warranty. If you have a fork still in its original warranty period and do not wish to void your warranty, please contact an authorized Cane Creek service center.

These service instructions cover the basic service procedures using standard service kits. If your suspension requires parts beyond standard replacement parts – CSU, compression rods, etc. – please consult your authorized Cane Creek service center or contact us at our Cane Creek Support Center.

Service Notes

These instructions cover just the damper leg of a complete 100 hour service. Combine these instructions with the appropriate spring side – air or coil; original or MKII – and 50 hour lower service to get a complete 100 hour fork service. 

Additionally, follow these instructions for damper removal and reinstall if sending the damper off for a service with an authorized Cane Creek service center.
