Can this seal be changed from the primary chain side ? Its a GB engine.

Thanks

Not really familiar with that specific engine Ross but the normal BSA unit single seal is done by taking the clutch off then removing the large alloy plate behind it. That gives you access to the gearbox sprocket, once that's removed you should be able to pry the seal out in situ.
