Probleme mit Rücklaufsperre bei alter Shimano Stradic Ci4+ 2500

[Belgian Joe]

Hello everyone,

I recently sold my old Shimano Stradic Ci4+ 2500 to a young angler from the neighborhood at a good price. It's the older model that has the anti-reverse switch.

After fishing with it for a while, the following problem now occurs: Under load (i.e., when pulled), the anti-reverse no longer engages and the reel spins backwards – almost as if there were no brake.

I've never encountered this problem myself. Does anyone have any idea what could be causing it? Could it be hardened grease or dirt in the switch mechanism or the roller freewheel?

Thank you so much for your help!

Could be grease in the anti-reverse bearing. Problems come up with falling temperatures, because even small amounts of grease lock the metal pins in their housing.

does this model have a anti Reverse bearing?
As I understand the referring model has a Anti Reverse Switch which means to me the anti Reverse is traditional mechanical or I am wrong?

Every Shimano reel from the past 20 years got anti reverse bearings, got nothing to to with permanent anti reverse.
Roller bearing instead of anti reverse dog, but this roller bearings need oil and hate grease
