Table of Contents

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 shocks have pressurized nitrogen and oil, even coil shocks. 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 shock 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 – shaft, damper tubes, end eyes – please consult your authorized Cane Creek service center or contact us at our Cane Creek Support Center.

Service Notes

The Air IL and Coil IL as well as the Standard and Trunnion and Previous Gen and Current Gen variants of both share many service steps. Some images in these instructions may not be identical to the the valve body or outer damper tube to the shock being serviced, but that is only when the process is the same for the shock in the image and the shock on your bench. When steps vary, that will be noted and images included.

General Prep

Clean shock. Record tune if desired. Remove hardware. Remove bushings if replacing. Unthread spring preload. Remove spring clip. Remove spring. Note and remove any stroke reduction clips.

Damper Disassembly

Step 1 – Gas & Oil Removal

***Use caution as nitrogen is pressurized.***

Standard Valve Body Degassing:
Loosen gas fill cover half a turn with 4mm Allen. Bleed gas with gas fill needle. Remove gas fill cover completely. Use pick to pry out gas fill plug.

Trunnion Valve Body Degassing:
Bleed gas with gas fill needle.

Oil Removal for Both:
Remove oil fill screw with T15. Remove slowly as there may be aerated oil behind fill screw. Empty oil through fill screw by cycling the damper.

Step 2 – Oil Seal Head & Shaft Assembly Removal

Clamp valve body in vise. Use Oil Seal Head Pin Spanner (BAD1174) to remove oil seal head. Remove shaft assembly from damper body. Pour out any remaining oil from damper body.

Step 3 – Preload Collar Disassembly

Remove set screw with 1.5m Allen. Remove detent ball and spring. Remove preload collar from outer damper tube.

Step 4 – Inner Damper Tube Removal

Using Inner Damper Tool Wrench (BAD1273), remove inner damper from valve body. Inspect interior of inner damper tube for piston band wear. Inspect damper tube threads and remove any remaining Loctite with pick. Clean thoroughly. Replace inner damper tube if necessary. Remove valve body o-ring and discard.

Step 5 – Gland Nut & Bladder Removal

Using T10, remove Climb Switch lever screw. Remove CS lever. Reclamp valve body in vise. Use Service Cradle (AAD2650) for Standard valve body. Using Gland Nut Wrench, remove gland nut. Breaker bar may be required. Pry off gland cover or end eye. Remove bladder with pick and discard.

Always use extreme caution when using a pick in this step or others to avoid scratching metal parts. Failure to do this can create scratches in the o-ring glands which cause leak paths for oil or gas. When possible, pinch and remove o-rings rather than using a pick.

Step 6 – CS Spool Valve Removal

Using a 1.5mm Allen, remove 2 set screws located inside of valve body next to inner damper tube purchase. Remove remaining set screw in valve body exposing spring and detent ball. Remove spring and detent ball. Using CS lever, unthread spool valve and remove. Pinch & remove and discard spool valve o-ring.

Step 7 – High Speed Adjusters Removal

Using 3mm Allen, dial High Speed adjusters in to gain access to High Speed circlips.
Remove circlips. Back High Speed adjusters all the way out. Pinch & remove and discard o-rings on adjusters.

Note that the Compression spring is 20wt (silver), rebound is 30wt (black).

Step 8 – Low Speed Adjusters Removal

Gently bottom out Low Speed adjuster needles with 3mm Allen. Rotate circlip until the end lines up with removal groove. Using pick, get behind circlip, remove and discard. Unthread and remove needles. Remove and discard o-rings.

TSN Disassembly (if desired)

TSN service is not required as part of a standard IL service. However, if the shock exhibits any audible sounds, usually a “chirp”, during use, this could be related to a bent TSN spring. No additional parts are required to do the TSN service. Images from Previous Gen DB IL valve body, but the process is identical to the Next Gen IL.

Step 1 – TSN Removal

Remove TSN stem from valve body using T15 from both High Speed valves. Clean valve body TSN threads with tap if green Loctite has built up on threads

Step 2 – TSN Disassembly

Disassemble TSN assembly by unthreading spring from the TSN stem. Remove TSN shim, piston and poppet.

Step 3 – TSN Inspection

Inspect spring for possible bent end of spring tail which can cause valve chirp. (Correcting bent spring covered in TSN Reassembly.)

Step 13 – Shaft Assembly Install

Apply thin layer of shock oil to piston band on shaft assembly. Use piston to apply layer of shock oil to inner surface of outer damper tube. Insert shaft assembly into inner damper tube, threading oil seal head into outer damper tube. Using Oil Seal Head Wrench, tighten oil seal head to 15 Nm. Ensure all three pins are properly seated and even pressure is applied to tool to prevent damaging tool pins. Reinstall preload collar on outer damper tube.

Step 14 – Climb Switch Install

Place Climb Switch on spool valve. Apply blue Loctite (243) to Climb Switch screw. Install Climb Switch screw. Torque to 1.2 NM with T10.

Step 15 – Shaft End Eye Install

Reinstall bottom out bumper on shaft. Apply red Loctite (263) to shaft and end eye. Finger tight end eye onto shaft. Work Loctite air bubbles out of end eye by going to full bottom and backing off multiple times. Clamp shaft into vise using shaft clamp. Using 1/2″ crows foot, torque end eye to 8 Nm.

Damper Fill

Step 1 – Fill Prep

Install new o-ring (AAD0532) on fill plug screw. Temporarily install end eye on shaft. Secure shock in horizontal position with fill port facing up. Back all adjusters to fully open and open Climb Switch. Thread IL G2 oil fill adaptor (BAD2651) into fill port. Fully compress damper. Attach oil fill machine per your manufacturer’s instructions. 

Step 2 – Vacuum and Oil Fill Process

Vacuum system to (4) mbar. Pressure with Oil to (3) bar. Slowly cycle shaft finishing with shaft fully out. Cut fill and equalize pressure. Vacuum system to (4) mbar, leaving shaft out. Pressure again with Oil to (3) bar. Slowly cycle shaft finishing with shaft fully out. Cut fill.

Step 3 – Valve Body Closure

Leaving horizontal, disconnect fill machine. Unthread fill needle. Drip some oil on to top of fill. Install oil fill screw with T15. 

Step 4 – Nitrogen Fill

Insert gas fill needle (DBT016) and pressurize to 11-12 bars of nitrogen. Compress shaft and ensure proper gas by observing shaft return to full extension. Submerge valve body in water to check for gas leaks.

Final Testing and Set Up

Step 1 – Dyno Testing

Set adjusters to factory neutral: HSC & HSR 2.5 turns from full bottom (or 2 turns from full open); LSC 11 clicks from full bottom; LSR 13 from full bottom. Using hand dyno, test shock for function. Ensure Climb Switch engages and operates properly. Turn individual adjusters to test each one. Set back to original tune if desired.

If mechanical dyno equipment is available, run shock on dyno at this point.
