Hi Max,
Much thanks for your excellent reply - hmmmm I completely see your logic - I'll have to monitor it and see if debris is getting in there, if so I'll remove the grease.
Thank you also for highlighting on the 550's drive shaft and gearbox assemby sheet that info on the box.....I did see that as after I posted this I went looking for a workshop manual.
I am figuring it's likely overdue for it's 'major service' so I might try and see if there's an easy way atleast to check on the quality of the grease thats in there already. I'm unsure if it's easy to access the gearbox or open, I couldn't see any obvious ways to do this but will have a poke around.
Much thanks again for excellent info and taking the time to reply - it is appreciated.
