SBS 340U in 242
-
hi everyone, do anyone know why this bus engine sound like motorcycle ? strange engine...
-
-
just to confirm, does it sound like 'chak chak chak', like some kind of gas is being pushed out type....
-
When it accelerate in high speed is would sound "Er..." ai ya dunno how to explain.. Just like a motorcycle accerlerating..
-
Maybe the ex-199 (on 179 now) drivers thrashed it too much...
-
No la, it had been a long time since it come to serve 242.
-
yah , always wondered why engine sound like that , when it brakes before it stops the bus jerks a little , it is usually driven by a chinese and indianBC
-
Hey dude, dont correct a bus enthusiast... 179 and 242 share buses...Originally posted by chickenlittle2:No la, it had been a long time since it come to serve 242.
that is why, at times, 242 gets the Leyland Olympian 3-axled DD buses...
and please, this is a dumb topic... -
Characteristic of the MB0405 on SBST. Probably bcos of the W3E gearbox disengaging?Originally posted by SBS BUSES LOVER:yah , always wondered why engine sound like that , when it brakes before it stops the bus jerks a little , it is usually driven by a chinese and indianBC -
AFAIK, no SBST Merc O405 sounds like motorcycle. So far, only 161U has a sound like SMRTB one.Originally posted by SBS3625D:Characteristic of the MB0405 on SBST. Probably bcos of the W3E gearbox disengaging? -
I think what he meant is there is a loud whirring sound coming from the back when the bus accelerates. I noticed it too.
-
it's the gearbox, not the driver.Originally posted by SBS BUSES LOVER:yah , always wondered why engine sound like that , when it brakes before it stops the bus jerks a little
ZF jerks a bit cos it is usually downshifting from second to first just before the bus stops. W3E, i can't explain why. maybe MS can. -
I actually meant that 340U (along with 341S & 286T), were once 199 buses... Then they all got transfered to 179 when it was introduced along with the super fast drivers.Originally posted by muziq bus:Hey dude, dont correct a bus enthusiast... 179 and 242 share buses...

Anyway, when 340U accelerated out of BNL today, there something like a bang sound!
But talking about weird bus sounds.... go listen to 9162H of 179... The engine goes tak tak tak tak tak and the ZF gearbox is very distinctive compared to other LOs... -
its 482T that is still with 242 once a 199 bus , 286T is a 197perm.Originally posted by stooper:I actually meant that 340U (along with 341S & 286T), were once 199 buses... Then they all got transfered to 179 when it was introduced along with the super fast drivers. -
286T USED to be 199 perm, before they split into 179 & 199...Originally posted by SBS BUSES LOVER:its 482T that is still with 242 once a 199 bus , 286T is a 197perm. -
No la long before Svc 179 had started, SBS 340U had transfer to serve perm in 242. SBS 482T is much later..

Hey, u r stupid enough, u do nt know how really this bus sounds then dun tok so much.. wat 3 leyland axle. I toking about SBS 340 U. A Mercedes Benz.

yup remember that in the 1990's it used the have the blue back desto when it was on 199 ...Originally posted by stooper:286T USED to be 199 perm, before they split into 179 & 199...
anyway the bus engine sounds quite weird . like someone moaning when it acclerates as chickenlittle2 said , i took it twice yesterday on 242 . -
i like the high pitch sound when the ECU kick in as the tachy needle go past the redline border
pity now no more driver accelerating fast..haix -
*cough* 179...Originally posted by ceecookie:pity now no more driver accelerating fast..haix
Last time on 3905X, the driver was already doing 60km/h before the 1st traffic light on Jurong West St 63... So fast that when someone wanted to flag the bus at the last minute, the driver tried to stop but couldn't! -
But do express 502 buses in PIE go after 60km/h?
-
All SBST buses speed cut@60kph. If the speedo can show something like 65kph then the BC must send in the bus for calibration. Else when accident is involved and found that the speed limitor not working, the BC who drove the bus will be in deep troubles. Cannnot blame workshop as the workshop staffs do not have the luxury of test driving every bus to check if it can hit above 60kph. I have caught BC who drove 80kph on faulty speed limiters of L3xle. I take extremely serious views on these safety gadgets. Because everyday our buses run on the road, must ensure no one dies or get hurt due to technical failures.Originally posted by chickenlittle2:But do express 502 buses in PIE go after 60km/h?
It's also not surprising that BC blame on the brakes not working during accidents. But workshop not stupid. In cases when BC say brakes suddenly not working... such things hardly exist. In fact to my experience, I think such things don't exist. Becos if air leak, the brakes can seize. One minute got brake, the other minute no brakes...

Now I also find out a lot of Volvo B10M Mark IV (DM3500) also got strange engine. Like sitting 5 tunnel (ARmy Truck)
-
Then I must say that the LOs on 161 all have faulty speed-limitors bcos all run on SLE with speed exceeding 70km/h throughout most journeys. I don't look at the speedometer on the bus, I use my father's car to check out how fast they go. The record though, goes to 965 MB0405 at 85km/h. I love the LOs when they speed, they are very stable.Originally posted by MS:All SBST buses speed cut@60kph.
