And on many occasions MMC claims that the rollers are consumable items such as tyres and brake pads, so even if you're under warranty you may not be covered and pay the huge bill.
The rollers will fail. That’s for sure at 100%. The unknown is when.
The Centa coupling is yet another half-baked engineering solution from Morgan. Anyone with experience of this type of coupling knows that the rubber inserts have a finite life. It seems even Morgan know this and yet they made no attempt to make them accessible, which would have been extremely easy at the production stage. Is there even any mention of inspection/maintenance requirements in the handbook ?
The catalogue of engineering incompetence on the M3W is quite staggering IMHO.
