Clutchless shifting on ST buses.

tifosikrishna · 16th February 2006, 16:37

Hi guys, today morning i left my vehicle for service and took a ST bus to office. as usual after buying the ticket, i went and stood at the nearest possible location to the driver and was observing him in action, if you had noticed these drivers,they seldom use clutch to change gears (they directly select the gear without using the clutch (DSG)) and this guy was no exception, and clutch is engaged only when moving the vehicle from stand still.... though there was a bone jarring noise everytime he engaged the first gear, i wonder how are these gearboxes able to withstand such rough usage???

could someone throw light on the differences between tranmissions o used in buses and cars... on the same token, i have observed that tata vehicles need much more usage of clutch than the leylands.

what will happen we try to do the same in our car ??

You will take the ST bus every day to work.

Bajaj Chetaks and Hero Hondas have been driven this way for ages.

Don't try this at home, anyone.

Those drivers wouldn't be doing it if they owned the buses they drive!!

Exactly.....they drive it like crap, and those vehicles remain crap.

as u mentioned jarring sound means the gears are not meshing in at the right time and sure it does need the clutch.
Always use clutch to change gears and LET IT NOT BE HALF CLUTCH press the pedal to the floor.

btw i had a bajaj superFE(company scooter) and after its first service at 600kms the bike was a dream only needed the clutch to get moving 1st gear and then gears would just fall with a slight twist of the wrist (no clutch) and it was never serviced until i returned the scooter back at 37500+- kms.
It all depends on how well the selector shaft has set in.

Somehow good things are always owned by company's or governments.
P.S. omit the ST buses.

I suppose the clutch systems in the buses are designed for "Double clutching" actually..... this is probably one reason why our ST drivers are not using the clutch at all.... it would be a pain to use the clutch twice everytime you need to change gears. Our ST corporations could do a lot better with auto-boxes...
