Is it on 11r24,5 tires? have counted the teeth. 5.17 ratios. no idea what tyres it had. currently rebuilding the forward drive axle. Bevel pinion has exploded.

Because the gear set is "mated" at the time of mfg, it will be correct. For Eaton 2spds it will be the "high ratio". Don't know how Mack does it with their double reduction. esp if someone changes the gear-set and doesn't re-stamp the ratio on the housing. yep all the housings are incorrect. front is stamped 8.24 rear is 5.01. The actual ratios are 4.17. Having fun over here 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74849-1979-r685rst/page/2/#findComment-563952 Share on other sites More sharing options...

The dad was a park ranger, and they had a Bell 47 helicopter. I don't think it was on one of the major networks here in the US, it must have been on one of the UHF channels Hell I forgot all about UHF now our TVs don’t even come with 2 knob’s lol bob and back in the day we only had like 3 major channels and 2 UHF not many choices.. bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74849-1979-r685rst/page/2/#findComment-563967 Share on other sites More sharing options...
Joseph Cummings Posted December 14 Share Posted December 14 In the early 60's all we had was VHF 3, 6 and 10. My uncle got a bunch of these converter boxes somewhere and came over and hooked one up on our TV, then we got 17, 29, and 48 UHF channels. I remember sitting on the floor with my cousin and we were thrilled that it was all cartoons. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74849-1979-r685rst/page/2/#findComment-563972 Share on other sites More sharing options...
mrsmackpaul Posted December 14 Share Posted December 14 As a kid we only had 3 channels ABC 2, BTV 6 and Ten One afternoon we watching cartoons Mum and Dad weren't home, they had gone to town for their monthly shop We were never allowed to watch TV until after 6 at night, Dad walked in and turned the TV off, my sister started going crook and chucking a wobbly A few moments later Dad carried a box in with a new TV, he plugged it and turned it on and marvels of modern marvels, it was colour My sister was so happy she burst into tears, Dad was like a rock star after that for a few days 🤣🤣🤣 BTV 6 was Ballarat and 2 and 10 were Melbourne and were on a different aerial, had a switch on the wall to flick to change between these 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74849-1979-r685rst/page/2/#findComment-563974 Share on other sites More sharing options...
mowerman Posted December 14 Share Posted December 14 Yes, I remember our first color TV 1966 me and my pops were watching it all day long and amazed how all our favorite shows were colorized wow speaking of which kind of off the subject on old body of mine had to wind up portable TV. That’s the only one I’ve ever seen in my life that was around 20 years ago he said people use them for camping. I don’t know how old this thing was. It wasn’t a very big set maybe 14 inches Quote Link to comment https://www.bigmacktrucks.com/topic/74849-1979-r685rst/page/2/#findComment-563976 Share on other sites More sharing options...
