I have created a "how to" series on YouTube which includes How To replace a one way bearing. Head over to mythicalRC on YouTube to see how easy it is!
simply drift out the old bearing with a round bolt head, or suitably sized round rod. then press fit the new bearing into place using a vice or similar. Just remember to ensure the bearing is the right way round ( turns in the right direction)
If you would like further assistance please ask, or if you would like me to replace the bearing for you, just buy one first so we can exchange details. (the only charge for this service is return postage)
