Re: Motor melodies and maladies
Went on 1124 today to get to Adelaide, and I noticed that it had a distinctive sound to it in a way. It reminded me of Southlink 3314 in 2014-2015, but much more audible.
Maybe these bland vehicles do have the odd interesting 'feature'. I have never heard a diff being this audible on a bus except when it's been one of the bearings sh_tting themselves.
On another note, went on 274 and it rode like sh-t as always. Definitely one of the worst 18.280s in service regarding ride quality. 2702 and 2705 are similar.

Re: Motor melodies and maladies
What's wrong with 2702? That one seems to be one of the best 18.280s in service with SouthLink, in terms of the condition it's in. At least, one of the best out of the dozen or so ones I've been on over the last year.TA3001 wrote:On another note, went on 274 and it rode like sh-t as always.

Re: Motor melodies and maladies
2702 just rides like sh!t like 2703 and 2705. It's as if it's got no suspension whatsoever.

Re: Motor melodies and maladies
2705 didn't seem to have anything wrong with its suspension when I last caught it. There are definitely a couple of 18.280s that would fit that description though.TA3001 wrote:2702 just rides like sh!t like 2703 and 2705. It's as if it's got no suspension whatsoever.

Re: Motor melodies and maladies
I went on 2705 twice in 2 school holidays on route 750, felt like my back had broken both times when I got off. Depends how it's driven really.

Re: Motor melodies and maladies
It must just be me then. I've got problems with many buses, but rough rides in my experiences are usually only on K-series Scanias.Lt. Commander Data wrote:I went on 2705 twice in 2 school holidays on route 750, felt like my back had broken both times when I got off. Depends how it's driven really.

Re: Motor melodies and maladies
While on he topic of rough rides, 3276/3277/3278 have extremely rough rides, not because of their suspension but rather their gear changes. They're so jolty it's ridiculous, at least CB80s have smooth gear changes.

Re: Motor melodies and maladies
I don't know what the problem is, but 1254 sounds almost like a K-series Scania rigid when in motion. At least it's not as rough to ride on as an O-Bahn Scania.

Re: Motor melodies and maladies
I could be mistaken, but I think 432 might have actually been repaired. It doesn't seem to be painfully loud at 50-55 kph anymore, and it only jolted into third once.

Was on St Agnes obahn bus 1113 today and that thing sounds terrible when the the retarder kicks it it reminds me of the days driving an old denning bus and the jake brakes are applied does anyone know if this has a diffrent retarder compared to others or is this bus just got a major issue?

Re: Motor melodies and maladies
It's an O-Bahn artic; probably a major issue.

Re: Motor melodies and maladies
It would probably be severe axle wear. More O'bahn vehicles are entering this category day by day due to the axles not being designed for the O'bahn.
And let's not forget that the diffs aren't suited to track work, on any of these vehicles. The hills stuff seems to be holding out ok, but not these much younger counterparts.

Re: Motor melodies and maladies
MAN SL202 CNG 1638 seems to be going the way of what 423 was like early this year. The condition of it's gearbox is causing vibrations when it changes into fourth gear, but they're not as unpleasant as what 423 was like before it was (surprisingly) fixed. I wonder if Newton will bother to do anything about it?

Re: Motor melodies and maladies
Third post in a row in this thread. But anyhow, Mile End CNG unit 1610 seems to be going the way of 1602 and 870 before they were fixed. It's noise is virtually identical, although not as loud as 1602 was.
Hopefully this unit can be fixed very soon, as it's rather annoying seeing one of the best SL202s in Adelaide going around like this.

Re: Motor melodies and maladies
It's hard to identify the source, but 1757 is making a strange sound. It could have been the AC unit, but I couldn't pinpoint it before I alighted.

Re: Motor melodies and maladies
I heard a driver reporting that it had developed an issue back in September. It sounded perfectly healthy (and great) when I last caught it, but it seemed to have slow acceleration going downhill, of all the places for a vehicle to not be able to pick up speed. The driver was running up to 7 minutes late at the time and did drive normally after that, though. I thought 442 had been fixed since then, but maybe not. 441 is still on the roads as of yesterday.jibb wrote:Light-City Buses St Agnes MAN SL202 Diesel 442 hasn't been around for a couple of weeks now.Don't know if its in the workshops or has been retired?

Re: Motor melodies and maladies
Just went on 1667 and I've never heard such a loud acceleration sound on a low floor before. It is louder than 422 as it gets to the required rpm to get it to change to second.
It would be interesting to catch on a hilly route like a 195 or 178 or something, just to see how long my ears can withstand it...

Re: Motor melodies and maladies
Some of Torrens Transit's NL202 CNGs are starting to sound much louder than normal. I think 1665 has something wrong with it. I don't think 422 is loud though; it still sounds fantastic even if I sit right up the back.TA3001 wrote:Just went on 1667 and I've never heard such a loud acceleration sound on a low floor before.

Re: Motor melodies and maladies
Torrens MAN 18.280 1507 seems to be developing a mechanical fault. It sounded very unusual going through gears the other day. I'm wondering if there will be another version of 1512 in mid 2015 roaming around soon....

Re: Motor melodies and maladies
Newton 1238 sounded like it's going the way of 2558 in early 2014. It sounded like something was definitely loose in the chassis, as it was very audible under the roof at West Lakes tonight, and I heard again as it took off.
However, a trip on this to see what it was like would have resulted in having to catch a 1940 series CB80 to get back though, so I didn't end up catching this rogue to see what it was like on the actual vehicle.

Re: Motor melodies and maladies
One of Mile End's beloved Ivecos seems to have developed that issue with the diff that causes that very loud noise in motion, number 1376. Was surprised to notice it heading through the city on this CB80.

Re: Motor melodies and maladies
SouthLink's 3271 had an aircon issue today, was making a very (loud) annoying noise.
3231 ("Fanny", named because of its radiator fan issue its had for over a year) now also has a rattle in the roof at the rear, can't even hear the fan from the inside now.
And speaking of aircon issues, 3203 was having issues today. When a fellow passenger asked the driver whether it was on, the driver simply laughed.

Re: Motor melodies and maladies
There seems to be more than just one CNG SL202 developing issues with their diffs lately. These are examples I've noticed recently:
1603 - Same as 859. Makes an audible noise when changing into fifth gear, and revs higher than usual.
1610 - Has the dreaded pinion bearing issue, which I've been complaining about to Mile End for about 2 months now, with nothing done about it. It's the same unpleasantly loud noise that 1602 made in 2015 for a while.
1623 - Highly audible noise
1630 - Going the way of 859. Noticed it the other day on a 178, in addition to it's fuel intake issue.
1633 - Makes an audible, but not particular annoying noise in motion. It's one of the few Newton CNGs I have actually heard getting on 60kph.
1640 - Enough said already about this rogue...
852 - Identical to 859, but would be likely to be driven at 40kph or less mostly.
859 - Same as 1603
I'm not sure that it's just age that is settling in with these units...
