mechohaulic Posted August 26 Share Posted August 26 have been sent a text from a friend making me aware of a short 5 minute video on youtube of good ole #1 Mack ::R607T=1001. as stated in the past my knowledge of posting pictures on here is limited. I did find the video simply going to Youtube video first R model Mack produced. I believe this is from this year at the show before Macungie. few facts are off by the narrator. felt good looking at the open hood and knowing I once rebuilt that engine, has since been done again years later by John (Rocky) Rockwell. the replacement to #1 was a "69 R611T -ENDT673 with jake and 13 speed RR. notice the B model shell supporting the radiator. basically a B-model with R cab.truck originally had a white top half with lower gold color cab. hood original/ doors have been replaced. does have an electrical issue ; reason for cover on floor between seats 2 Quote Link to comment Share on other sites More sharing options...
70mackMB Posted August 26 Share Posted August 26 Found it Mech. Nice five minute video. Wonder why there wasn't a BCR emblem on it? .....Hippy 1 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted August 26 Author Share Posted August 26 B C R's weren't "invented "yet. that unit was only suppose to be a demonstrator, not for sale truck. the R's were still in the trial stage . while at Mack waterbury. I assisted on two B C R conversions early '70's. with the R's gaining popularity and the days when things were repaired not junked and new bought many B models starting to rust out from age and new England salt. you didn't scrap a good drivetrain/chassis ; just updated. someone at Mack had some smarts to think of the BCR. instead of manufacture/stock B cabs ; make use of this new style cab called an R. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post BOBWhite Posted August 26 Popular Post Share Posted August 26 This it? What an unassuming truck to be #1! If I saw it at a show I probably would've walked right past it without even realizing. 5 1 Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted August 26 Author Share Posted August 26 as spoken on here numerous times : back then things were simpler with way more common sense . cab conversions didn't require computers and miles of electrical wiring. that hood is very heavy to tilt, radiator being smaller then opening has the two side extension panels. that front Mack emblem should have an armed guard; LOL don't know if another exists. always wondered if serial # 1002 still around ? many yrs back a truck newspaper had an ad for the first U model U607T 1001 for sale .must be scrap by now. 1 Quote Link to comment Share on other sites More sharing options...

Vladislav Posted August 26 Share Posted August 26 From what I could see in the video the truck has R-model frame rails with typical R-model front spring hangers and cab mounts. But the radiator core is tiny indeed. Neat looking old R-model and definitely a great piece of trucking history! Thanks for sharing. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...

mechohaulic Posted August 27 Author Share Posted August 27 B C R short term stands for (B)model (C)onverted to (R)model. with changing times then as earlier written ; many contractors /truck owners had older B models which cab wise were showing some age yet the lower end:: rails drive line had many miles left. much like farmers of the day , equipment was repaired ;not replaced. Mack ingeniously came up with the conversion idea. also I'm sure it had to do with promoting the R model . the two I became involved in building were B model dumps which mysteriously caught fire in a garage and only to the cab section. alum fuel pedals were a blob of melted alum on the transmission. remember the cabs being unpainted outside but fully groomed inside. memory loss on the cab/hood mounting change over. was a couple of years ago== 1972.1974 ????? 1 Quote Link to comment Share on other sites More sharing options...

BOBWhite Posted August 27 Share Posted August 27 How many years was the BCR program available? Was it through the dealer or did they send them back up to the factory to be reconfigured? I've seen pictures of R's with the BCR emblem on the side but had no idea what It meant until now. Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted August 27 Author Share Posted August 27 B C R's were done at dealerships. while at Waterbury Mack '69-'75 . I worked on 2 b's converted to R's. can't say longevity of the program sorry. went back to pictures I posted way back on my profile; one is of ole #1 in the garage hooked to a reads screening plant. thought I might have put picture of the engine/transmission on back of my '77 ford -nope. 1 Quote Link to comment Share on other sites More sharing options...

convoyduel Posted August 30 Share Posted August 30 BCR’s also stand out because they typically lacked the R model battery boxes behind the front fenders and often retained the B fuel tanks. My ‘67 R611F (1003)and my ‘68 R608F (1006) both have the very small radiator with the side extension panels that look like closed shutters. My ‘89 R688ST tractor of course has the full radiator/ATAAC setup. 1 1 Quote Link to comment Share on other sites More sharing options...

Yeah, I've seen several trucks that had U-bolted fifth wheels where they welded blocks on the frame rails to keep them from shifting back and forth. 1 Quote Link to comment Share on other sites More sharing options...
