brickhouse15 Posted June 25, 2018 Share Posted June 25, 2018 Good Evening, As you can see in my attached photo, my B61 mack has braces welded onto the trunnion tube. It seems to be leaking oil, and I'm not very experienced with truck suspensions. Would I be better off replacing the trunnion tube and stand, or trying to find a Mack cutoff and just going the total update route? This is a 1962 B61, and I believe it has 54,000 rears. Thanks!

MACKS Posted June 25, 2018 Share Posted June 25, 2018 If your talking about the cap that's welded to the bar it's supposed to be there and there is no oil just Greece. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53663-mack-trunnion-tube/#findComment-401306 Share on other sites More sharing options...
brickhouse15 Posted June 25, 2018 Author Share Posted June 25, 2018 The caps have cracks in them. Is that a big deal? Quote Link to comment https://www.bigmacktrucks.com/topic/53663-mack-trunnion-tube/#findComment-401307 Share on other sites More sharing options...
mrsmackpaul Posted June 26, 2018 Share Posted June 26, 2018 No the cracks are fairly common Looks like the oil is coming from much higher up looking at the trunnions Paul Quote Link to comment https://www.bigmacktrucks.com/topic/53663-mack-trunnion-tube/#findComment-401326 Share on other sites More sharing options...
j hancock Posted June 26, 2018 Share Posted June 26, 2018 Depending on what you find for a problem and how you plan on using the truck in the future, swapping to a newer setup would get a better gear ratio, etc. Quote JimIt doesn't cost anything to pay attention.

brickhouse15 Posted June 27, 2018 Author Share Posted June 27, 2018 Thanks guys, I appreciate the input. I'll probably just weld the cracks, and run it!
