I decided today was the day I would remove the covers from the transmission and check and clean if required.
The good news was it was nice and clean, I did observe some signs of the belt hitting the bottom of the casing. One other observation regarding the casing. It was showing signs of surface corrosion, not major but visible. Not surprising when you see where I live, surrounded by sea, well 320 degrees anyway.
The belt casing showing the slapping effect, dark colour at bottom.
I cleaned the covers and replaced them, whilst I was in the area I decided to give the rear wheel a spin to check it for wear and such. A couple of tiny silver dots, mmmmm, looks like the shank of a nail or such, checked them out, no problem just flecks caught in the rubber. Then I noticed a rusty coloured speck. Gave that a tiny prod with a screw driver and the tyre sealant started to ooze from it. Expletive at this point.
What to do? Do I leave it in and let the sealant do what its paid for or do I change the tyre?
I elected to change the tyre. Over 6k miles on it and it is looking like it's past its best. So a couple of phone calls and a new tyre will arrive on Friday. £66 fitted balanced etc. (£66 = $104US)
Then came the job of dismantling the rear wheel assembly. Which I did seconds before it started to precipitate!! Phew!
A big thanks to those of you that have posted pictorials and posted regarding the above subjects you really did help immensely in my work this morning.
