Popular Post The Heinz Posted yesterday at 05:11 PM Popular Post Share Posted yesterday at 05:11 PM (edited) Steering arm but not Pitman arm, I would assume it would be one of these below: No87 is 5QH3281B, superseded to 25119672. No105 is 5QH3245B, superseded to 25115926. Both are available to order from Mack.

Paul1890 Posted 9 hours ago Author Share Posted 9 hours ago Hi I wondered if you would have drag link part number I think I want to change it also i have the link that has the ball and socket with spring you tighten up on Pittman arm ball it appears there are a couple of different lengths thank you Quote Link to comment https://www.bigmacktrucks.com/topic/75473-79-dm-steering-lever-part/#findComment-574912 Share on other sites More sharing options...
Geoff Weeks Posted 7 hours ago Share Posted 7 hours ago Drag link looks from the pictures, that it is made up of "tie rod end joints" and an adjustment tube. I found it simpler to just measure and order the ends for my Marmon drag link that is like that. Trying to order anything for a Marmon almost always gets you nowhere. You have to do the homework yourself but most things are always available. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75473-79-dm-steering-lever-part/#findComment-574915 Share on other sites More sharing options...

This is stupid easy to order, they don't even have to look it up! The drag link is 13QC45BP28, it's been obsoleted from Mack, and PAI seems to have given up on it as well. Not sure where else to look other than having one custom made.

67RModel Posted 4 hours ago Share Posted 4 hours ago Not necessary related to this thread but more or less just a curiosity of mine is how parts become obsoleted. Like who sits around and studies parts breakdowns and says we are no longer going to have xyz part available anymore. How can one part of the same assembly be easier to get than a loaf of bread but the one it attaches to has been NLA for a decade or more?

Geoff Weeks Posted 4 hours ago Share Posted 4 hours ago My guess it is all done by computer, they look at the sales figures and base solely of number of units moved over a set time period. One would hope some note of how critical the part is would play a factor but I doubt it.

The Heinz Posted 4 hours ago Share Posted 4 hours ago Sales figures probably has a lot to do with it, we somewhat purge old inventory when we have a chance.

Geoff Weeks Posted 4 hours ago Share Posted 4 hours ago IHC sold all their old inventory to "Parts depot" and sometimes it is amazing what is still available NOS. Want a new rear hub for a 1940's rear axle, yep we've got one (just be prepared to pay through the nose). Does Mack doing anything similar?

The Heinz Posted 42 minutes ago Share Posted 42 minutes ago They sold a lot of obsolete parts to a company called Lippert, but it's very spotty what they have.
