Quick video for you ........................ a noisy and rough feeling classic old school shimano Stradic GTM4000. A strip down to the bones revealed a bearing on the pinion gear that must have had some water ingress that's affected the bearing and pitted it, rendering it noisy and feeling rough.
The reel has been completely stripped bare, all gearing and remaining bearings checked, relubed, and the reel reassembled and regreased, along with a brand new bearing fitted, taking it back to ' good as new'.
See the video below and hear the difference before & after !
Thanks for watching ;)
