NY-B61 Posted November 20, 2014 Author Share Posted November 20, 2014 Thanks for that. I really wanna poke around one someday.....old technology is so much cooler than modern crap! I agree. The mechanical evolution of the motor truck has happened at warp speed, relatively speaking. We've gone from Daimler then to what we have today in the space of 118 years. Then there's the evolution of body and aerodynamic design, fuel and lubricant formulation, tires, electronics......... all in a nanosecond.How can you futz up diagnosing and fixing a chain and sprocket?

Popular Post fxfymn Posted November 20, 2014 Popular Post Share Posted November 20, 2014 To me the warp speed change in trucks occurred in the first two decades of their design. Many of the design features of my 1925 AB are very similar to what is used today; evolution instead of revolution is what has occurred.In contrast the 25 was designed and engineered within the first 10 years of automotive history with a design that was built for almost 20 years. Pretty remarkable to go from steam engines and horses to that in 10 years. 5 Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

Joe Ditchkus Posted November 21, 2014 Share Posted November 21, 2014 At the speeds they reached back then I do not think liquid sloshing around was a big problem, Although stopping them would have been with brake system Paul described going down some grades. Its amazing they ran triples somewhere back then and they are still not allowed in Penna.or most Eastern States. It took us until the 1980'S to get doubles. Joe D.

NY-B61 Posted November 21, 2014 Author Share Posted November 21, 2014 Was it an old Texaco truck? I believe so. It was definitely used as a fuel truck of some kind at some time.

Superdog Posted November 21, 2014 Share Posted November 21, 2014 I've seen old pics somewhere of a Texaco AC with the same emblem in place of the traditional Mack logo.

NY-B61 Posted November 21, 2014 Author Share Posted November 21, 2014 I'll ask the gentleman when I see him next. Up close, the Texaco logo doesn't look like it was made in a high school metal shop, it looks integral to the truck.

j hancock Posted November 21, 2014 Share Posted November 21, 2014 I remember reading that the service brakes were on the small drive sprockets and the parking/hand brake was on the axle drums. There was a comment that the drivers were more apt to use the hand brake. The reason for that was if there was more slack in one chain than the other it could lead to an uneven initial application to the rear wheels. The hand brake could be adjusted to give a more consistent brake action taking the chains out of the equation.Back in the day when there were fewer flip flop drivers. 1 Quote JimIt doesn't cost anything to pay attention.

b615rich Posted December 29, 2014 Share Posted December 29, 2014 I'm in the processor taking apart a 1924, see more pics in the gallery if you're interested. I'm pretty sure the AK's had front brakes - they were very similar sheet metal but a six cylinder, electric starters, etc.The brakes are simple and probably effective, it's a monster band around the drive sprockets and large brakes in the wheels, but all lever/rod activated. The tranny and crankcase and other parts are very high quality castings. The hardware is so well made most parts come apart with surprising ease. They were produced for about twenty years, ahead of their time and very heavy duty compared to most of the other trucks of the day. As for sheet metal, the hood on the truck above looks amazing - it is a complex design with many angles in the metal.. That truck is really nice! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/37784-chain-drive/#findComment-272216 Share on other sites More sharing options...

Popular Post b615rich Posted December 29, 2014 Popular Post Share Posted December 29, 2014 41Chevy. Thanks for the brochure pics, they definitely made a lot of improvements over the run. My shifter is primitive compared to the pics you sent, and no vacuum or front brakes. Mine was a crane too - found this old picture of it on line, but the crane was scrapped. I guess you drove slowly and down shifted often - no to mention steering! Sorry, look closely it was behind a spring shop for years. 4 Quote Link to comment https://www.bigmacktrucks.com/topic/37784-chain-drive/#findComment-272244 Share on other sites More sharing options...
