sw4400 Posted February 24, 2014 Report Share Posted February 24, 2014 It's still the Cummins ISM7 engine. I wouldn't think they put a Cummins ISL7 engine for those busses 1XXX < 1630. You are correct, garmon757... the ISM7 engine was just rebuilt/rehabbed(same thing, different words). I enjoy knowing this stuff!!! And I can safely say I'm right!!! Apologies to the rest of the forum members... I just had a bad few days because of one member, and this broke me out of the shell because Diesel Engine knowledge is a strong point. Happy rant aside!!! Quote Link to comment Share on other sites More sharing options...
garmon757 Posted February 24, 2014 Report Share Posted February 24, 2014 I was correct on the Nova LFS 6400's having Cummins ISC Engines, the New Flyer 5800's had Detroit Series-50, as did Flxible 6000-6304, Flxible 5300-5744 and 5766-5769 had Detroit 6V92TA, TMC RTS had Detroit 6V92. New Flyer had Cummins ISM(1000-1629) and Cummins ISL(1630-2029)... I have sources to find out, but won't reveal them to you... and I can determine engines, especially diesel engines by sound... I grew up around a diesel bus garage!!! I can tell you International School Buses from the late 80's through 2003-2004 use 7.3L Diesel Engines(now 6.4L(2005-2008/9 and 6.7L(2009-Present) Powerstroke Diesel Engines), Transit School Buses(Flatnose) with the engine in the interior by the driver are powered by a 5.9 Cummins Engine(late '80's-2006)6.7 Cummins(2007-Present). Small Ford E-Series School Buses are powered by the same 7.3L, 6.4 or 6.7L engine depending on year of bus. Chevy School Van Buses are powered by the 6.5L Duramax Diesel Engine(6.2L GM Diesel engine before the 6.5L was made in the '90's). So yeah, name that bus engine by sound I'm good at.... I know I was very young at the time when the Flxibles were in service but I think 5730, 5741-43, 5746 and 5748-5764 may had a different engine (based off the silverish wheels just like the 6000s). I remember 5744, 5747, and 5765-69 had the Detroit engines before they were retired. You are correct, garmon757... the ISM7 engine was just rebuilt/rehabbed(same thing, different words). I enjoy knowing this stuff!!! And I can safely say I'm right!!! Apologies to the rest of the forum members... I just had a bad few days because of one member, and this broke me out of the shell because Diesel Engine knowledge is a strong point. Happy rant aside!!! That's what I've thought about them being rebuilt. What sense does it make to swap engines if all of the New Flyers are not the same?

Busjack Posted February 24, 2014 Report Share Posted February 24, 2014 I know I was very young at the time when the Flxibles were in service but I think 5730, 5741-43, 5746 and 5748-5764 may had a different engine (based off the silverish wheels just like the 6000s). I remember 5744, 5747, and 5765-69 had the Detroit engines before they were retired. ... There were decals on the black masking just left of the front doors saying Cummins, and Krambles's book said that 20 had Cummins L-10 and 5 had DD 6V91, instead of most having 6V92T. Also, the Pace specs did have a distinction between rebuilt and rehabbed--there were three contractors: one provides its own rebuilt engines, another provides its own rebuilt transmissions, and the third yanks out the old ones and installs what the other two provided. The specs called for what [was in the 2600s] ISB 5.9 and Allison B300R "or equivalent." Maybe the engines and transmissions taken out of the buses were rebuilt and "recycled" into later buses, but the buses were not supposed to be out of service for the length of time it was to rehab the engines to keep the same one in the same bus.

andrethebusman Posted February 24, 2014 Report Share Posted February 24, 2014 What is the difference between an ISL and an ISM engine? Quote Link to comment Share on other sites More sharing options...
andrethebusman Posted February 24, 2014 Report Share Posted February 24, 2014 As part of the rehab, is the issue of defective(?) circuit breaker controlling the external lights of 1430-1629 being addressed? On any given day, large percentage of these buses are running around with only headlights and stoplights working, which is a major safety issue after dark.

If you listen to rehabbed buses in the 1000-1429 range though, it sounds like those buses have ISM7s instead of their original ISM6 engines.

garmon757 Posted February 24, 2014 Report Share Posted February 24, 2014 What is the difference between an ISL and an ISM engine? Cummins ISM engines have better power and torque than the ISL engines. ISM's have an electronic fuel injection while the ISL's have a High Pressure Common Rail fuel injection. ISM's are more compatible with all transmission models than ISL's. However, ISL's are more compatible with conventional driveline and hybrid ready configurations than ISM's.

YoungBusLover Posted February 25, 2014 Report Share Posted February 25, 2014 I wonder why #1000-#1004 have not been rehabbed but yet #1005 is. Quote Link to comment Share on other sites More sharing options...
jajuan Posted February 25, 2014 Report Share Posted February 25, 2014 I wonder why #1000-#1004 have not been rehabbed but yet #1005 is. As been mentioned a few times before, 1005 was the prototype for the rehabs. Plus CTA is not doing the rehabs in anything resembling numerical order. They'll just get to them when they get to them. 3 Quote Link to comment Share on other sites More sharing options...
BusHunter Posted February 25, 2014 Author Report Share Posted February 25, 2014 I'm taking #1086 off the rehabbed list. It shows no signs of rehab, not even an updated clever device. Quote Link to comment Share on other sites More sharing options...
dann Posted February 25, 2014 Report Share Posted February 25, 2014 I'm taking #1086 off the rehabbed list. It shows no signs of rehab, not even an updated clever device. My bad. When I rode it I thought the lighting looked different, it seemed to ride better and the seats somehow looked cleaner; I'll admit I wasn't paying attention to the clever device or the handicapped seat inserts.

LOL I was just about to say both #1196 and #1291 were rehabbed! I don't understand why they didn't fix #1291's number decals on the back of the bus. It's all torn up making it hard to see the numbers unless you're really close by it. Quote Link to comment Share on other sites More sharing options...

I'm surprised you didn't see #1298. It was #1196's leader. Spotted #1292 which wasn't rehabbed yet with the lights. It passed by so quick I couldn't tell if it was mechanically rehabbed or not. I guess I'll have to keep it on the list until I know for sure. Quote Link to comment Share on other sites More sharing options...

BusHunter Posted February 28, 2014 Author Report Share Posted February 28, 2014 I've spotted both of them around 3pm while I was chowing down some Panda Express on Adams and Michigan. I saw all of those, around 5 or 6, around the same spot. Saw #1619 on the #60. #1545, another rehabbed bus, on the #62 had some heavy vandalism on it at the inside rear. Someone wrote with a really thick heavy black marker on the lighter color fiberboards (or whatever you call it) close to the floor and there was some bad etching around the window frame. I don't know why but 74th's buses have the roughest looking rehab buses. #1583 had nearly the same problem with the etching. Quote Link to comment Share on other sites More sharing options...

BusHunter Posted February 28, 2014 Author Report Share Posted February 28, 2014 It's because of lack of decency when it comes to people. I wonder if that's from Curie HS. They have had problems in the past on the Orange line with heavy vandalism at Pulaski/Orange and with the #3200 series cars. I believe Pulaski was the first station to have the glass covered over with the metal templates on the orange line. Quote Link to comment Share on other sites More sharing options...

Whether it's from Curie, Englewood, or any other high school, vandalism can happen anywhere at anytime. CTA is not invincible from it.

It has those same blue kneeling decals that #1018 has that's on the rehabbed buses. Well if that's the case, then #1091 is partially rehabbed. I wouldn't count it yet until the LED lights are installed. Quote Link to comment Share on other sites More sharing options...
garmon757 Posted March 2, 2014 Report Share Posted March 2, 2014 Shots of rehabbed #1553 @ 69th/Ashland. Pay attention to the second pic guys because it's very key!!! It's like a secret compartment on top the tire (that didn't exist when the buses were delivered). If y'all see these on any of them then those buses are rehabbed.
