SBS9806J SG

SBS1956L (even though it is ZF) also make a whistle sound

MS SG

seen the video. Laughing why whould you think the noise is from gearbox?If I say its a combination of all rotating components would you believe?

there're a lot of myths going around. really. Don't assume. Ig you go underneath the bus with engine running and listen. Then while the bus is on the dyno go outside and listen also. You'll have a different view.

stooper SG

So you're saying the video starts when the bus is already in its 2nd gear?

SBS9806J SG

Are you saying it is engine sound?

Scania N113CRB luver SG

Ya at the start of the video, the bus is already in the second gear. Wink

Scania SG

The first one sounds little bit like a MAN SL200 when acclerating.

ZYX2005 SG

u ought to learn that buses have similarities globally.

for example, a MAN is a MAn is a MAn in hong kong, Ll or singapore. the dash configuration and designs r similar. always mercedes like looking. thats how one mnges to identify buses let alone look at the VIN.

in our case,

the Zf gearbox in Singapore fitted on whatever model u got here will have the same gear ratios if fitted on a similair model overseas. one example i cna think of is the VSO SBS9888Y compared to hong Kongs VSO.

Yea! MAN is always Mercedes like looking, especially the front axles! Look at the front axles and compare it with the O.405s, they are very similar. Razz Wonder why MAN looks so similar to Mercs? Rolling Eyes

then how do people come to different conclusions? is it necessary that people must think like how you think? Laughing

It simply means one is correct and the other is misguided.

SBS3625D SG

I asked a BC for fave bus and he pointed to the MKIII and an 0405. Laughing

As for breakdowns, I've come across many occasions of stuck ZFs, but 1 Voith (9844Z) to date.

SBS3625D SG

1 noticeable feature of the voith gearbox is that it tends to hold the 1st gear much longer than the other 2 or 3 geard. Can be inferred that the ratio of the 1st gear is significantly higher than the ZF counterpart.

When the gearboxes wear out, for voith, there will be very noticeable stickiness in shifting down gears and in some cases, the shifting up will have a noticeable lag time. For ageing ZFs, there will also be higher lag times in between gear switches and very noticeably, the lock-up clutch does not kick in if the bus is accelerating fast. If it does when the bus is accelerating slower, then instead of the characteristical kick, you get teeth grinding sounds instead.

Both also dont have ZF gearboxes Laughing Except for SBS876R and SBS877M. Mr. Green

The new video, now all three are put together, unlike separately like last time. Razz

Shocked You sure it won't kick in? Do you have an example?
Everyday I take the LO3x and the driver floors the accelerator, no matter what, the lock up will still kick in.

Scania N113CRB luver SG

TIB1182J sometimes dont, almost near 2nd gear then kick in. Especially when its fully loaded and BC puts full trottle. TIB967T has no lock up, strange. Confused

SBS1985C SG

Some Mercz have ZF gearboxes.

SBS1985C SG

Most 29 BC prefers Scanias as compared to MK III or MK IVs. Maybe thats because they are "used to" driving the N113s.
