Daiwa pluton 200sh

Someone gave me this reel to service and had no issues with cleaning or lubrication. However ,When I push the thumb bar down sending it into freespool it won`t go into drive when the handle is turned.I took the cover off and noticed that when the thumb bar was pressed the clutch cam wasn`t going in the channel to engage the clutch gear trip. The clutch spring looks good.What can be wrong?
