B9TLs that vibrate badly

Even VSO operated well... Sadly they are not WAB ):

B9 roaring uphill at 60km/h opposite SP yesterday. FTW. -
SBS7421Z way back in 2007... WORST than the 199 B9TLs IMO as in the LOUD moaning handbrakes!

Good B9TL = SBS7485P.
Of late, ZF B9TLs starting to have problems when shifting from 5th-6th gear. the 5th gear hits rather high rpm at 60kph but rather low rpm at 6th. and i notice B9TLs that run along eways, tend to switch 5th-6th-5th-6th alot. nowadays when B9TLs hit around 60kph at 5th gear with rather high rpm and cant change to 6th, they give obnoxious vibrations which is uncomfortable for passengers and bad for the gearbox itself. should reconsidering setting limit to speed at 55 since these horses can pick up real fast. but its gonna get people cursing haha.
would be good if SBST increase the speed limit to 70 but i'm probably dreaming. i'm sure if safe driving is inculcated, 70 is still a safe speed and buses wont need such tight schedules. or retune the gearbox, making it unable to attain 6th. tightening of acceleration to buses is also another tale to longer running time.

Anyone taken SBS7474X on 143 lately?
It vibrates like as though there is a construction going on. Especially when you're on the upper deck and more of to the back, it makes a drilling sound that you hear on the roads.

Hope SBST will convert them one day by installing the ramp and backrest for PIW.HK VSOs are WAB for info.
Cheers.

yeah.I also hope so although i tink its very unlikly to happen.. :(
My fren told me kmb refurbished one Scania N113 DD which the fleet was abt to be scrapped.Tat DD was also converted to WAB as a trial to see whether those old buses were able to be WAB fit or not.So it sort of became lik a demo as it was the ony major refurbished one.I dunno if tis is true or not.. -

Yeah so. I think you have too much comments. I believe you should keep them to yourself. If a bus doesnt have vibration, then something will be wrong.

agreed. actually KUB EEV sometimes can get stuck at the 5th gear because it has no opportunity to change to the 6th gear by the time it reaches 60km/h on the highway.

If there's excessive vibrations, something is wrong.Anyway, anybody knows the size difference between the 5th and 6th? Seems pretty large to me in comparison to that between the other gears.

Of cuz its possible.But in Singapore,its a diff story wit all the strict rules on buses by lta..
Talking abt tis,i wonder wat will happen to the CNGs n VSOs since their lifespans r ending aft 2020 in 2022.Dunno if sbst will bother to make them WAB or replace them wit newer buses :(
If they wan replace them wit newer buses,will the CNGs and VSOs be sold since they havent reach their lifespans yet or be scrapped since they ony have 2 more years to go?? -
i feel that only a small number of b9's and a large number of kub's vibrate vigorously forever. not all vibrate vigorously forever. its the bush thing thats concerned. some exceptions like 7333 and 8350 are forever vibrating.

I believe more CNGs or even hybrids will enter service, but not so soon. Talking ab CNG, actually we are even lagging than our 3rd world neighbour.Cheers.

Excuse me, If a bus vibrate moderately, would i be here commenting? The bus vibrates vigourously. So what if i have too much comments? You don't like, shut up lah. No need to to make a fuss what? Anything wrong? Afterall this thread states B9TLs that vibrate badly. 7474 is vibrating badly. Not like i post a scania that is vibrating badly what?
PS: I'm not here to waste my time arguing with people who is not worth arguing with.
Still want to carry on, PM Please

The china one rite?It was said lik towards the end of last year.but aft tat,no news of it at all.
I cant even rmb if it was mentioned whether if it was for SMRT or not in the 1st place.It cld be for some pte operators too. -
No need 70,65kmh ardy can shift to 6th gear.65 and 60 kmh a lot of different.Got several OCs that are lock til 65 still manage to reach 6th gear.
