JoeH Posted March 19, 2022 Share Posted March 19, 2022 Bought a harbor freight 1 inch gun, and 10" long. Claims it goes to 1500 ft lbs. Our other 1" gun had the long shank, wouldn't fit under there. Ran the gun til it pretty much doesn't tighten any more...

Ricky Beals Posted April 26, 2022 Author Share Posted April 26, 2022 Well gang just not w getting to the suspension. Pulled it all off and Trunnion bar looked good until we got to the passenger side. There are hardly any threads left. The whole bushing just slid off the bar. The bar was in really good shape, no cracks in welds but I don’t see anyway around not replacing the bar. Not going tack weld the nut on it. Probably call Axle Surgeons in morning.

Popular Post Ricky Beals Posted April 26, 2022 Author Popular Post Share Posted April 26, 2022 The bar is smooth just a lot to f grease on it. We pulled the bed and had the cylinder repacked. Changed out hydraulic fluid in the tank. Getting the old girl ready to start hauling. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496082 Share on other sites More sharing options...
mrsmackpaul Posted April 26, 2022 Share Posted April 26, 2022 Well I dunno, there cant be much sideways force on these as the spring on the opposite side would stop it pulling and vice versa If the elephant ears are in good nic you could probably run it with no nuts at all Or at least thats how my mind see's it Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496086 Share on other sites More sharing options...
Mark T Posted April 26, 2022 Share Posted April 26, 2022 From the looks of the pictures, someone put a trunion stand in that truck already. If you have the body off, you're not that far from just replacing it with another Mack one. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496087 Share on other sites More sharing options...

Popular Post Ricky Beals Posted April 26, 2022 Author Popular Post Share Posted April 26, 2022 Honestly this hasn’t been that hard of a job since we took the bed off. We talked about putting a new Trunnion stand in from Mack. I’m thinking the price was around 3500.00 and a lot more cutting and pulling the rear tandems out. The biggest factor is waiting on it to arrive and we are looking at another week. I have decided to go with axel surgeons and wrap this up this week. Bottom insulators were trashed. Anyway wanted to post up and let you guys know I didn’t fall off the face of the earth. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496096 Share on other sites More sharing options...
Mark T Posted April 26, 2022 Share Posted April 26, 2022 The axle surgeon might even have a way to make it work. Maybe even restore the threads on it enough to get by. Paul's right about it not being such a bad thing if the rest is tightened up. Not perfect, but it'd go considerably longer than you might think 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496103 Share on other sites More sharing options...

Joey Mack Posted April 26, 2022 Share Posted April 26, 2022 from what I understand, there will be a new bar installed on thursday. I know that I have had this repair done 4 times, and all went good.. and cost effective as well.. If I dont t have to pull the A-Frame, I call Axle Surgeon.. the last one I had done a few years ago, was $1500.00 total... not sure what todays price is.. jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496122 Share on other sites More sharing options...
Ricky Beals Posted April 27, 2022 Author Share Posted April 27, 2022 I did inspect the bushings and they were not worn all the way thru. I’m like you guys this isn’t the original Trunnion stand. The bar looked really good just those threads were gone on one end. Yes everything is new on rear suspension and I’m talking everything. Replacing brakes while I’m back there. These guys are out of Little Rock which is central Arkansas and I’m down in SW Arkansas about 130 miles from them. They quoted 1800.00 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496142 Share on other sites More sharing options...

Popular Post Ricky Beals Posted April 29, 2022 Author Popular Post Share Posted April 29, 2022 Macks I didn’t see this until this evening. They came and went. It was just one guy. He took a grinder and cut a slit below the Trunnion bar in the stand. He then drove a couple of small chisels into those cuts. He then cut the bar right behind the stand on both sides. Took a 20lb sledge and knocked out both side. He then took the new Trunnion bar and slicked it up and we put it in one side of stand and drove it thru the other side. He welded everything up and was gone. Took him 2 hours. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69366-bronze-bushing-change-on/page/3/#findComment-496324 Share on other sites More sharing options...
