    I ordered a gallon of Sta-Lube 140 wt. gear oil. It`s not mineral oil but that shouldn`t be an issue.
  2. skydawg
    I thought Penrite 140 mineral gear oil would be a good choice,but can`t find it here.What is a good equivalent to the GO-A mineral oil that Mack listed in their service manual? Thanks.

    The pin is tapered,no notch.So,given all the conflicting posts,I`m not going to pursue this,I`ll keep everything greased and drive it.Spent $300 on parts I was told were correct,and they`re not.Lack of parts and info will be the reason fewer of these great beasts will be on the road every year.

    So when that seam closes when installed in the knuckle,there`s no way the pin will fit w/out reaming.
  5. skydawg
    Here are pics of a bushing on and off the kingpin,you can see the spread in the seam needed to fit over the pin.
  6. skydawg
    The grease "grooves" in the bushing don`t go all the way to the top and bottom,so it seems like grease wouldn`t be able to exit the bushing,even without seals?

    I hope you`re right,DCW....this is all new to me,I don`t know squat. Mecho,the holes in the bushings are not in the center.Is there a shoulder inside the knuckle for each bushing to seat against?
  8. skydawg
    I didn`t gat any grease seals in the kit.I don`t see any in the Figure 9-9 pic that DCW posted.Can I re-use the old ones if I have them? If I spread the bushing seams by hand,they fit over the pins,but I`d think they would need reaming when installed in the knuckle,since they`re a no go over the pins when the seam is tight.

    The bushings have 2 holes,180deg apart.These are nos Mack parts,#301SQ32B.
  10. skydawg
    Here are my parts,the bushings are steel and are split,not a continuous circle.
  11. skydawg
    They`re threaded...easy peasy once I got a filter wrench that was big enough.

    Great pics,DCW,thankyou.I believe my truck has the Type 3,Figure9-9 setup.So the taper of the pin in the axle bears the weight,and the adjusting nut on the bottom moves the knuckle up or down slightly to maintain clearance w/ the axle?
  13. skydawg
    It must be threaded because a sharp knife blade will not even penetrate the joint when I try to hammer it in between the cap and the hub.
  14. skydawg
    I`m looking to remove the spoke hub grease caps without denting them...and without buying an $80 pr of pliers.I`m wondering if a strap type oil filter wrench would get it moving enough to get something behind it to pry it off?
  15. skydawg
    I got the kingpins and bushings,the pins are tapered but the bushings and their respective locations on the pins are not tapered.So these won`t require a tapered reamer.Does this sound like the correct parts for a FA 505 axle/knuckle? I`d hate to have a shop disassemble only to find that I gave them the wrong parts(nos Mack 301SQ32B).It would mean leaving the truck outside at the shop in a not-so-great area until I came up with correct parts,or putting it back together w/ the old pins...at $110/hr.

    Ok,I`ll try that,thanks.Leaving tomorrow for Vermont,be back Thursday.

    So AFTER I bought the 301SQ32B kingpins,I looked at the build sheet for my truck and the part# is 301SQA32C...did I just waste $300? I did have my brother help w/ the problem ID,and he said the kingpins are loose,also driver side tie rod end and drag link have too much play,He`s an excellent auto mechanic but not equipped or experienced w/ big trucks.He thought it looks like the drag link play might be taken up with a screw on the end.

    Joey,my email:skydawg999@gmail.com,and thank you.DCW,are there any special tools required,other than that reamer? I`m a back yard guy,can jack it up,but don`t have a shop.I`d give it a shot if it`s something an average guy could handle.
  19. skydawg
    Ok,I just bought the 301SQ32B Mack OEM set on ebay,should fit my pre`62 FA505 axle(I hope).I`ll have to find a shop to install them next.Many thanks to everyone,you guys are the best!
  20. skydawg
    Are the sets still available? Who would be a good supplier to contact? Thanks.
  21. skydawg
    With either front tire jacked off the ground,I get about an inch and a half of movement when I grab the tire at the top and push and pull.This occurs equally w/ left and right tires.I`m guessing this isn`t good,even though the front end feels solid going down the road...no shimmying or wobbling up to 50 mph,which is as fast as I`ve gone,so far.This is a 1961 B61 w/ an FA505 axle.Can anyone help in diagnosing the problem? Thanks.
  22. skydawg
    I`ll back in from now on...I like the front view of the cab from my window,but will swap for rear view.
  23. skydawg
    Yes,slightly uphill,street tread,bobtail.Thanks Mech.
  24. skydawg
    1961 B61 w/ triplex trans...when backing out of my gravel driveway,my truck starts jumping and bucking,no matter what aux gear I`m in.Forward starts are smooth.Am I doing something wrong? Thanks.
  25. skydawg
    Maybe he was stuck in Lodi,NJ.
