Hi Nick, I drove for Dunedin City Transport 1972 to 1976 , what great memories I've had with this blog driving this bus, the world masters wre from 134 to 142, and I remember specially the 142 advertising Tiger tea, great memories and a great channel, by the way I'm a pom, left NZ in 1976. Cheers Nick.
Love the exhaust brake on this. Sounds like the ones on Sydney's Volvo B12BLEs from the 2000s which have unfortunately been quietened or disconnected altogether. I don't know what you did there at 5:39 but it muffled the mic from then sadly. Beautiful bus, looks labour intensive to drive lol.
You mention the gearbox as being the same as the one in Bristol double-deckers, isn't it also in the AEC-branded ones from the 1940s (on the basis that pneumocyclic means "preselect"-move lever to 1, press gear change pedal, move lever to 2, get moving, press gear change pedal once going fast enough for second gear, move lever to 3...)?
Yes, looking at it, I'd say it's AEC/CAV Monocontrol gearbox, as opposed to the Leyland Pneumocyclic equivalent. The same type was fitted to Leyland Atlanteans, for instance, as well as AEC Reliances, Swifts and Regal VI( export) models.
Hi yudasgoat , it’s not a preselect. It doesn’t have to be a pre select to be Pneumocyclic, Pneumocyclic is a name used by SCG and later Leyland when the merged. This is the system which is low voltage electrically assisted , I.e similar to the Leyland branded system in the Bristol I mentioned vs the fully air controlled system non electric Pneumocyclic you will see in my Leyland Leopard and Anlantean videos. That was always my understanding, I maybe wrong
Highly unlikely, in fact almost certainly not. The reason for the 'spoked cross' steering wheel is that you tug the wheel round by it's spokes when very slow or stationary. I have seen a 'helper' assisting with turning the wheel in tightly spaced manoeuvring. The real pain is how many turns it is from lock to lock.
@@jamesfrench7299 It's not normal at all and it's not good for the engine either. It probably has a pneumatic governor, which is quite different from a hydraulic one that would be built into the injection pump.
@@jamesfrench7299 I remember. It wasn't until I came across an engineering manual years ago that explained it, including what goes wrong and how to fix it. It be that the system just needs a clean up to make it work properly. The idle is nice and smooth and the engine runs well when they're properly set up. From what I remember, it's the pneumatic governors that tended to do this although other types will 'hunt' like this when something is not quite right.

Similar body shape to the 1962 AEC Reliances we had in Wellington back in the day. Only 7.7 litres with the same gearbox.

I used ride that bus model under NZRS and School in 70s and 80s.
Excellent video, Nick. Well done 👏
what rpm is that engine idling at lol, thats crazy
Leyland Tiger sounds really good but I still prefer the Volvo B10M. 👍
Get some taste millennial.

@@robertmaidment-wilson564 Pre select is 3 pedal and the bands are operated by the operating pedal. Mono control is a semi auto two pedal

Is there power steering in this beast?

I'd say so. There's no way he'd be able to spin the wheel around like that without.
Armstrong power steering...
@@robertmaidment-wilson564 You'll be surprised, he has a lot of experience driving buses old and young.
That engine needs it's governor adjusting to sort the idling.
That's normal for these and I love it. It's surging.

@@DelticEngine plenty of old Leylands did this.

@@DelticEngine gives it extra character on top.
