andrethebusman Posted September 22, 2014 Report Share Posted September 22, 2014 I was always under the impression that 5735-5744 were the only ones with 6L-71N (Inline) engines, with 5500-5534 having standard 6V-92TA's like 5300-5499. 5765-5769 had particulate traps that were removed after a couple of years. Had the big "bulge" in the interior ceiling in the rear. Quote Link to comment Share on other sites More sharing options...

I didn't add it because it's specification are perfectly detailed on its page under "Buses". Not to mention the 1000 series' specs are quite varied in terms of engine and transmission combinations depending on fleet number groups.

ctrabs74 Posted September 28, 2014 Report Share Posted September 28, 2014 I was under the impression that both the 4333s and 7900s had Allison transmissions and that the 6000s all had ZFs. Quote Link to comment Share on other sites More sharing options...

I'm not sure if any Nova bus models are compatible with any Allison transmissions also if anybody can clarify that. 6305-6329 Cummins L10 engines had more horsepower than 6000-6304 Detroit Series 50's making it extremely compatible with a ZF transmission.

If you read any bus assembler site, just about any can put a ZF, Allison, or Voith transmission in any diesel bus. Nova spec sheet; New Flyer specs (click on propulsion), The only thing distinctive about Allison is that they have the predominant parallel hybrid drive.

I've riden the 4300 diesels and am positive that I saw an Allison transmission gearbox. I didn't have a chance to ride a 7900 Nova yet, but from the video I saw, I thought those were Allison transmissions. Quote Link to comment Share on other sites More sharing options...

That's not really correct since NFs 1930-2029 aren't electric either but all 100 of those have Allison transmissions. So it is possible for 4333-4399 to have Allison transmissions.

sw4400 Posted September 29, 2014 Report Share Posted September 29, 2014 Powertrain for the TMC RTS should be Detroit Diesel 6V92, not 6V92TA. Listen to this 6V92... it sounds very much like a TMC on takeoff... 1 Quote Link to comment Share on other sites More sharing options...

So it is possible for 4333-4399 to have Allison transmissions. Confirmed by the rehab specs.: If that's the case then why cta didn't purchase them for 4333-99??? The antecedent is indefinite, but it seems a combination of (1) this was a rush procurement for the Red Line South project based on Seattle options (2) and if you can get anything out of the 50-150 articulated bus procurement Q&A that a ZF transmission would not meet CTA specs for acceleration of a 60 foot bus, including an XD60.

Listen to this 6V92... it sounds very much like a TMC on takeoff... Krambles's book.page 54, says in the caption to the Metro picture that the majority of the 1991 order was 6V92T, while testing 20 Cummins L-10 and 5 DD6v91s. However, he doesn't say anything directly in the caption to the TMC picture. But, to support your assertion, you would need proof that the 4400s had different engines (i.e. no turbochargers) compared to most of the 5300s.

Busjack Posted September 29, 2014 Report Share Posted September 29, 2014 Fair enough. Do you think cta sticks with Allison's for future buses? I suppose that's a question similar to whether they will use Freedman Gemini seats for future buses or go back to American Seating--it is an option that may make sense for certain reasons, but doesn't make much difference on the bottom line (maybe in this case the transmission did). Another possible factor is Buy America requirements (60% U.S. content) in that Allison is in Indianapolis and ZF is a German company, although it has plants in the U.S. BTW, it appears that GM split off Allison, which is now an independent company.

I'm not so sure that Buy America has much to do with why CTA opted for Allison transmissions in the 4333s (and presumably 7900s). Voith, if I'm not mistaken, is also a German company and has their transmissions on new buses that post-dated the 4333s; Denver, as I recall, also specs their buses out with ZF transmissions.
