Gearbox???
Can't they just replace???
Yeah, 'SBS2656X' is right for once. Those gearboxes aren't in
production anymore. It's not the same as gearboxes in cars. But I
think it has something to do with the repair costs VS the revenue
the bus will bring before it's dead at 19 years.
If the costs to find a new gearbox is too ex, I think they
rather let the bus go off early than waste time find a new gearbox
& then fit in onto 1929R. What's more, it's not like they have
a lack of SP buses.
But some of the SBST MB O405s of old did have a mix of Voith
& ZF gearboxes though after their initial ones died. But IIRC
those were fitted before they were 17 years..so more economical
sense I guess.
