tom1361 Posted February 25, 2018 Share Posted February 25, 2018 (edited) hello everyone, i know this discussion has taken place many times before. i have read most of the previous posts. i am trying to get the proper kingpins for my 62 b 67 with the fa505 axle. i called transedge mack in allentown and gave them the 1qha # and they came back with 301sq32c. now that number is what's on my build sheet from mack. however 32c reverts back to the 301sq32b and that's no longer services from mack. that's all well and fine, now i go to the aftermarket. most of us know the aftermarket pins are coming up short at 6.69 inches and use the fancy roller bushings. my pins are coming in at 7 5/16 or 7.31 inches. now the moog [#8592b] kit says it fits or replaces the mack numbers:::: 301sq32b , 301sq45a and 301sw45a however they are just like all other aftermarket kits with the seals and short pins. i took a look at my ts 442 manual dated 10/67 i got from mack and in section 9 page 11 it shows type 1, 2 ,3 and 4 steering knuckles. the type 3 knuckle [the one i have] changed at some point in time. the first diagram [figure 9-9] shows the knuckle i have with standard bushings and no seals. the next diagram [9-10] clearly shows the newer type knuckle with the roller bushings and seals. what year was this knuckle first used?? has anyone attempted to use the aftermarket pin kits?? i'm assuming that it can't be done since the pins are to short?? if anyone has i'd like to know how it worked out. where might i be able to get the correct pins from other then a machine shop? my last question is where is the stamped part number on the steering knuckles?? the number stamped under the pin cap is not the correct number [4qh 476 dp4] mack ran it for me and it didn't come up. thanks for your help. tom vb.
