15mm Thru Axle to QR Retrofit

Tools Needed: 22mm wrench or adjustable wrench, Terrain 9mm Quick Release Axle Kit (Contains 2 black conversion caps)
While disassembling the hub, keep all loose parts organized on a clean rag or paper towel. Proper re-assembly is very important to rider safety. Be careful not to damage threads or aluminum nuts. This kit only works in American Classic Terrain disc front hubs.
IMPORTANT: START ON THE DISC MOUNT SIDE

1. Using a 22mm wrench, turn counter clock-wise to loosen and remove the large black threaded cap.

2. Remove large black threaded cap.

3. Remove 15mm adapter.Each cap has a small lip at the base. This lip sits inside the large black threaded cap so it does not fall out.

4. Place the Terrain 9mm Quick Release cap lip side down so that the lip sits on the inner bearing race.

5. Place the large black threaded cap over the Terrain 9mm Quick Release cap and thread into the hubshell. This cap has no bearing adjustment and should be tightened down.
   FLIP HUB OVER AND START ON THE NON-DISC SIDE
   NOTE:
   There is a rubber O-ring at the bottom of the threads on the non-disc side. Grease the threads and be sure the O-ring is in its groove before continuing.
   Turn the hub over and repeat Steps 1 – 4 to install the non-disc side 9mm Quick Release end cap.

6. Thread the cap on over the 9mm Quick Release end cap.

7. When you tighten the threaded cap:

  * Do Not bottom out the cap.
  * Threaded cap must be snug, not loose. Do Not ride with a loose threaded cap!
  * Do Not overtighten the threaded cap, it will bind the bearings and may damage the O-ring.![american-classic-Terrain-Front-Disc-Hub-15mm-Thru-Axle-to-QR-Retrofit-03](https://manuals.plus/wp-content/uploads/2022/11/american-classic-Terrain-Front-Disc-Hub-15mm-Thru-Axle-to-QR-Retrofit-03.png)
