The boys might have taken it off for repair. Quote Link to comment https://www.bigmacktrucks.com/topic/30193-77-dm-600/page/3/#findComment-171844 Share on other sites More sharing options...

RFCDrum Posted March 14, 2013 Share Posted March 14, 2013 I agree Rob, twelve speed is # 1 in my book. Driven a lot of Macks with other trans. but the twelve is the best with the compound on the floor.Two things with a Mack the damn mud stick was right against your leg and the AC unit.

Green Dash Posted March 14, 2013 Share Posted March 14, 2013 I thought a U model passenger seat was cramped even when I was 10 years old, but the offset cab was interesting enough to keep me distracted. 1 Quote Jim Link to comment https://www.bigmacktrucks.com/topic/30193-77-dm-600/page/3/#findComment-172119 Share on other sites More sharing options...

oilburner Posted March 17, 2013 Author Share Posted March 17, 2013 Hauled with the old truck this week, i have a broke spring on the left side so i only let them load it to the top of the stakes, been hauling 20 ton a trip and about 3000 feet of logs with it. It is slow 48 is a good speed the tach don't work so i don't know what the engine is doing but at 55 mph it sounds like it is screaming. I do get down to 3th gear and about 8 mph on one hill on hwy 297, that is called hells point, but for a 36 year old truck it does ok i just wish it had some more speed or just run 55 at a lower rpm. I still have not took any pictures sorry guys i will try to rember tomarow to snap a few i downed the rear suspension to change the spring and pads when i found a bad truion bushing, and the pads did not have the spacers in between them on the sides. while laying under the truck i notice the trans looked biger than the old six speed in the floor of the shop, and i found the i.d. numbers in a diffrent place, it has x107 on it does any one know what trans that would be and the ratio, i am thinking that it may be a overdrive because the guy i got it from told me he thought it had 4.50 ratio, but it does not i cleaned up the carrier and it says 5.13 and the model is a c 113, any info would be great, and i will get some pics as soon as posible it is just hard to rember when i get in the truck at day light and get out at dark, but i will be putting it back together so hopefully i can snap a few with my i phone.

oilburner Posted March 17, 2013 Author Share Posted March 17, 2013 If it is not a overdrive i would like to change the tranny out for a overdrive, it runs the engine to death out on the road, with the 5.13 rears, but i would have to find a trans that would work good with the little engine. The engine runs like a top, sweet running 237, i found the tag above the bosch pump that says it was built in 10 mouth of 84 so it had the engine replaced not the original. Also it has a oil bath breather, is it easy to change it to a element style or do i have to find a whole breather off a later model. I have thought about putting a 15 speed over in it or a mack 9 speed, if the tranny does not already have a overdrive, what do you all thank, i could change the rears a good freind of mine has a set of cut off 55 with 4.17 ratio that i could buy and drop in my carriers but it may kill what little power i do have with the six speed, i thank that would but the truck up around 70 or 75 mph.

2stacksuperdog Posted March 17, 2013 Share Posted March 17, 2013 You should be able to put a regular air cleaner on it. As for the transmission your better off staying with a mack tranny considering mack motors produce so much torque they have a tenancy to blow roadrangers apart. You could get a overdrive 12 speed which is arguably the best transmission ever built Quote Matt Link to comment https://www.bigmacktrucks.com/topic/30193-77-dm-600/page/3/#findComment-172723 Share on other sites More sharing options...

j hancock Posted March 17, 2013 Share Posted March 17, 2013 I think the overdrive ones were X107A."A" is for air shift. Loose the second lever and gain the air selector.X1070A would be an air shift overdrive.Jim Quote JimIt doesn't cost anything to pay attention.

oilburner Posted March 17, 2013 Author Share Posted March 17, 2013 Ok so from what i understand my trans is a dirrect six speed with mutiable reverse gears, so i can swap a 12 speed or a mack 9 over and get the rpms down at highway speeds, and sorry about the pictures every time i send them from my phone that is what happens, havent figured it out yet, so thanks for the comments Quote Link to comment https://www.bigmacktrucks.com/topic/30193-77-dm-600/page/3/#findComment-172794 Share on other sites More sharing options...

oilburner Posted March 17, 2013 Author Share Posted March 17, 2013 Make sure they are overdrive and it should help you out.yes i really need a overdrive, i was running back empty the other day and i got it to 58 for just a secound that was everything it would run, i thank that a overdrive would give me 10 to 15 mph on top and that would help calm her down at highway speeds.
