Is it true that the 1982 and '83 Orion I's--the U.S. versions finished in New York--used the Allison HT747 transmission (rather than the original HT740) behind their DD 6V92TA engines? I'm talking about those buses as run by such agencies as: Pacific Transit System (Raymond, WA) Milford Transit District (Milford, CT) Montachusett Regional Transit Authority (Fitchburg, MA) Yakima Transit (Yakima, WA) SLO (San Luis Obispo) Transit (San Luis Obispo, CA) San Luis Obispo Regional Transit Authority (SLORTA) (San Luis Obispo, CA) GATRA (Taunton, MA) IndyGo (Indianapolis, IN) Waukesha Metro Transit (Waukesha, WI) The 1982 GATRA Orion I's are unique in that they were the only such 35-foot units finished in NY to carry the old model 01.504, since most of these got out with the model 01.506, which continued into part of 1984 (the year both the 01.504 and 01.506 were replaced by the 01.507). Did these three buses, numbered 8217 to 8219, use the Detroit Diesel 6V92TA engine and Allison HT747 transmission? ~Ben
Does anyone know exactly all of the Rockwell front and rear axles that were used in the Orion I bus in all years 1976-1993? This is information I'm hoping to get added to this page in the future: http://cptdb.ca/wiki/index.php?title=Orion_Bus_Industries_%27Orion_I%27 Older Orion I brochures (and my 1981 TMC City Cruiser brochure) list the following: Front: model FF931, 12,000 lbs. GAWR Rear: model R143, 23,000 lbs. GAWR From the 1983 Orion brochure that I have: Front: model FF932, 13,400 lbs. GAWR Rear: model R143, 23,000 lbs. GAWR But in 1984, the 35' and 40' buses (the latter of which was introduced that year) went for higher-rated axles. Front: model FG943 or 17100, 14,600 lbs. GAWR Rear: model 59742, 25,000 lbs. GAWR The 30-foot models also had a newer front axle that year in model FF942 (13,200 lbs. GAWR) but retained the R143 rear axle. In 1988, Rockwell introduced these new rear axles: 30 foot buses: model RC-23-160, 23,000 lbs. GAWR (replaced R143) Buses longer than 30 feet: model 61142, 26,000 lbs. GAWR (replaced 59742) To round things up: 1976-1979 models: FF931 front / Q148 rear (34,000 lbs. GVWR) 1980-1982 models: FF931 front / R143 rear (35,000 lbs. GVWR) 1982-1983 models: FF932 front / R143 rear (36,400 lbs. GVWR) 1984-1987 models: 30 foot: FF942 front / R143 rear (36,200 lbs. GVWR) 35 and 40 foot: FG943 or 17100 front / 59742 rear (39,600 lbs. GVWR) 1988-1993 models: 30 foot: FF942 front / RC-23-160 rear (36,200 lbs. GVWR) 35 and 40 foot: 17100 front / 61142 rear (40,600 lbs. GVWR) Some questions I want to ask you all: 1. Did Orion ever catalog the Rockwell FG943 front axle (14,600 lbs. GAWR) for their 1984 I's (models 01.507 to 01.510)? 2. Did Orion ever catalog the Rockwell Q148 rear axle (22,000 lbs. GAWR) for their pre-1981 I's? Thank you very much! ~Ben
http://www.angelfire.com/ca/TORONTO/builders/orion1.html I'm hoping we can create a database of complete serial numbers for the 1982-84 Orion I deliveries. These serial numbers have the line sequence number representing characters 12-14 in the VIN number, which started at serial no. 457 (C5356457 goes to Markham Transit #2016, delivered 5/1982) and ended at serial no. 999 (E5563999 goes to Whitehorse Transit #14, delivered 7/1984). The first U.S.-built Orion I carried the serial number C6001449 (goes to Pacific Transit System #D10, delivered 7/1982). However, the 1982 Orion Is delivered to Toronto Transit Commission (8730-8739) may not have had the line sequencing in their serial numbers. You can see, when you read the info in the link above, that it gets rather messy when you read the serial numbers for the Grey Goose Bus Lines deliveries... even the line sequencing in these serial numbers is out of order in places. Confirmed serial numbers are listed for units 125 (D5493730) and 160 (D6702732, possibly one of the few U.S.-built Orion Is to go to Canada) among these deliveries, both delivered to said agency in September/October 1983. For example, let's figure out if these University of Virginia bus serial numbers are correct: 5139 - D6659661 5239 - D6669674 5337 - D6670675 ~Ben
Here's some Orion I VIN numbers from this link: http://notes.brandon.ca/tenders.nsf/0965fee38275b21186256ab0006ab633/2a3410cb38be0308862575080075ff51/$FILE/For%20Sale%20by%20Tender%20-%20Transit%20Buses.pdf #34 - 2B1129274C5414536 Model: 01.504 (35 foot) Year: 1982 Delivered: 11/1982 Engine: Detroit Diesel 6V71N Transmission: Allison MT644 #35 - 2B1169K74K5001955 Model: 01.508 (40 foot) Year: 1989 Delivered: 7/1989 Engine: Detroit Diesel 6V92TA Transmission: Allison HTB748 Other: Initially delivered to Toronto Transit Commission as #9360 with Cummins L10G CNG engine and ZF ECOMAT 4HP500 transmission; initially resold to GO Transit as #1713 with original ZF transmission replaced by Allison HTB748 transmission (and also sent to Calgary Transit where it was demonstrated as #8510); when re-resold to Brandon Transit in 1998 as #35, the L10G engine was replaced by the 6V92TA engine. #39 - 2B1169275H5001665 Model: 01.508 (40 foot) Year: 1987 Delivered: 8/1987 Engine: Detroit Diesel 6V71N Transmission: Allison HT747 #41 - 2B1139775K5002257 Model: 01.507 (36 foot) Year: 1989 Delivered: 9/1989 Engine: Detroit Diesel 6V92TA Transmission: Allison HTB748 #43 - 2B1139777M5002957 Model: 01.507 (36 foot) Year: 1991 Delivered: 11/1991 Engine: Detroit Diesel 6V92TA Transmission: Allison HTB748 ~Ben
