mrsmackpaul Posted September 5, 2022 Share Posted September 5, 2022 Does anyone have a list of ratios available for 58,000 pound axles ? Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 Hello Paul,. I may have info. Are the rears 200 series or 112/113 Carriers? I can check my books tomorrow, and hope to help you.. what year-ish are they? Jojo 1 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 5, 2022 Author Share Posted September 5, 2022 1980 Dunno about the series of carriers, tell me what to look for and I can report back with better info Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 I believe back then, 1980, they still stamped the info on the front just below the input housing, on the smooth curved part of the main housing.. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 Paul, For some reason I am not able to send pictures to my Email from my phone. I have a picture of a chart that may help you, but my normal way of sending pictures is not working.. Hopefully, when you clean the paint off the front of the carrier housing, you will see the series and ratio.. i expect it to be 112/113 series.. I'm trying, Jojo Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 5, 2022 Author Share Posted September 5, 2022 Thanks Joey Went for a look see and returned with some info Looks like 113, I have never had a issue with these at all so have never looked before These were 5.73 ratio when new and for some reason I thought they had been changed to 5.29, Vlad pulled me up one day and said there was no such thing, I don't know but said I would find out next time I'm under there Looks like 5.32 to my eyes, reckon they would be the original carriers with new gears put in as 58's are pretty rare out here Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 looks like 5.32 : 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 5.32 is a legit ratio. I have a chart that I want to send you but I dont have a phone number to text to, or an e-mail.. of course I respect one's privacy.. ... Jojo Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 there is no 5.29:1 on my chart,,, Vlad is a reliable person, for sure... jojo Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 5, 2022 Author Share Posted September 5, 2022 Yes Vlad was right, just getting out and going for the day over Have sent you my email address Joey Thanks for helping Yeah, I have no idea were I got 5.29 in my brain from 5.32 is plenty slow enough and would give you blokes a fit if I drove on the states at 55 MPH all day like I do out here Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 5, 2022 Share Posted September 5, 2022 Wouldnt bother me.... I want to move the load, not win the race... however, if you have to haul many loads in a day, the bossman will be on youre a$$.. I did a few years in construction pulling dump trailers and some 'wheeler work',, I always was 1 or 2 loads / day shy of the seasoned guys, But I never tried to get a speeding ticket as well.. anyway.... jojo 1 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 6, 2022 Author Share Posted September 6, 2022 Photo of ratios sent to me from Joey So after discussing this with Joey I reckon it would good to share this info with all as these questions are asked plenty of times on here From the chart above (correct me if Im wrong Joey) On the left hand vertical column of the main group of numbers is ratio of the top half of the diff center I am calling the top half the bit that turns the drive to a right angle So once I establish that I can then go across the line horizontally and find my ratios that are available with that top section of gearing So my truck had 5.73 to begin with, now has 5.32 So I find those two numbers and that tells me what ratios are available if I only change the lower section, from 4.64 - 6.48 If I only change the top section and leave the lower gears as is I can have from 3.87 - 8.90, that is starting at my 5.32 as my base ratio Is this correct Joey ? Paul Also let me know if it isnt okay to share this stuff Joey and I'll delete it Seeyah Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 6, 2022 Share Posted September 6, 2022 your doing good Paul, to use this chart to the fullest, the carrier needs to be taken apart.. as far as the spur and bull gear, my bet is they will remain. the top reduction (bevel gears) is where you will make your adjustment, however,, i have always built these with stock replacement sets, and I would use the mearsurements for shimming, and to make sure I had the right gears.. I also wish It wasnt 5 or 6 years ago when I built one.. you can also count the teeth on the gears and dived them into each othe to get the 2 gear ratios, (bevel gears + Spur and bull gear)... I hope others will come in and add to or correct me if needed... You Got this Mate... Jojo Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 6, 2022 Author Share Posted September 6, 2022 So 112/113 carriers, were these used in only 58's or were they used in 44's as well ? Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 6, 2022 Share Posted September 6, 2022 I just sent you an e-mail.. it is still sending, check it in a bit.. I'm sending pics from "Mack" books, instead of my brain.. jojo Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 6, 2022 Share Posted September 6, 2022 (edited) 50K and up to 60 k-ish were 112/113, back then,, 92/93 were below 50K, the 112/113/ had a stronger spur shaft housing and I think the bull gear is a bit wider... Much like the 200 series, if memory serves me right.. I do know the 200 series was a stronger setup than the 92/93 series, as I described.. jojo Edited September 6, 2022 by Joey Mack more content needed Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 8, 2022 Author Share Posted September 8, 2022 From a email from Joey yesterday I noticed in the second picture down it says that 200 & 201 can be used in 50 and 58,000 pound axles What ratios are there for these And is 200 for 50,000 pound and 201 for 58,000 pound?

Joey Mack Posted September 8, 2022 Share Posted September 8, 2022 200 is front 201 is rear.. jojo Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 10, 2022 Author Share Posted September 10, 2022 I gather thats the same for 112/113 and so on Do you have the ratios for the 200 series carriers Joey ? I have no idea were I'll find spare carriers for 58's in Australia, first I need to work out what ratio I'm looking for Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 10, 2022 Share Posted September 10, 2022 as Far as I know, you can use the same ratio's... The 200's are strong, but I have seen many 92/93's do a great job.. I dont see an issue... and 92/93's are everywhere, so you can hoard a few to do what you need to do.. I dont think I helped much Paul... I really hope a smarter guy chimes in... jojo Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted September 10, 2022 Author Share Posted September 10, 2022 So do the other carriers fit in ? As in the 92/93 fit the 112/113's axle housings Im thinking but have no idea the spider gears would have to be changed tp suit bigger axles I know notjing about this stuff at all so any help is helpful Paul Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 10, 2022 Share Posted September 10, 2022 the mount bolt pattern is the same.. after around 2010-ish i think is when they added another bolt inside the carrier housing.. so your good... as far as the axle housing, how it is mounted into the truck is different, as you know.. spider gears in a Mack rear end are housed inside the bull gear, so no need to go that deep in that.. if you get the chance,, get a blown up mack rear from a friend and tear it apart.. as smart as you are you will say...
