I want to change the oil and generally give these a good service but can’t find a manual for that level of work – the original only covers simple pre-ride drill. I’ve previously stripped RC36 Hollowforms but not sure how the RC38s come apart. I have the lowers off and the circlips out at the crown but not sure which way the innards come out – upward or downward. It’s a while since they’ve been serviced so they may be a bit stuck.

Advice welcomed.

Cheers.
