hicrop10 Posted Thursday at 10:25 PM Share Posted Thursday at 10:25 PM I am thinking of doing this to make the painting that much easier.Has anyone here done it before.It doesn’t look all that tough to do.My biggest concern is it has 65,000 lbs rears and canal back suspension.The truck has moved 100 ton before so I’m concerned with anything springing and not able to get it back together. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/ Share on other sites More sharing options...
mechohaulic Posted yesterday at 12:09 AM Share Posted yesterday at 12:09 AM if you have the set up and capabilities to SAFELY separate the units; would definitely be a better way to go. can check for worn parts etc . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562338 Share on other sites More sharing options...
cruiseliner64 Posted yesterday at 01:48 AM Share Posted yesterday at 01:48 AM I have never done a Mack camelback suspension but i'v done a lot of Hino rear suspension which is very similar.(almost a copy with a few small differences in my opinion).It is very heavy work and a lot of lifting gear,forklift,jacks and cribin is needed as well as an inch air socket tool.As Mechohaulic said its a great oppertunity to check all the wear parts and do a great paint job.Good luck with it and if you do it put plenty of pictures.The truck looks great by the way...

hicrop10 Posted yesterday at 01:00 PM Author Share Posted yesterday at 01:00 PM crusieliner64, I don’t think any of the parts that may be worn out would be available.I am mostly doing this to get the paint job right.I know that no one will be crawling under the rears to look and the fifth wheel will cover most of the top but I will know. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562360 Share on other sites More sharing options...

Yeah I totaly get you there.I am the very same.. just want it to be spot on.I was just pointing out it is a big job but its great satisfaction to know its done.I was inquiring about Camelback parts for our Cruiseliner and I was told theyre still availible.Our truck is plated for 150ton operation so it would be same as yours maybe???

Mack’s,no removing the caps won’t do it.I have to remove the 10-1 1/2 locking nut and the 2 torque rods on top.Then I will be able to slide them out. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562372 Share on other sites More sharing options...
mowerman Posted 19 hours ago Share Posted 19 hours ago Frankly, I don’t think it’s worth the effort to do all that for a very little gain, but it’s your decision. You can’t really do much more than you already did to get at everything. But then again, if you do not pull it apart, you will be laying awake Knight thinking about it or at least I would be….. As far as you’re going with that truck, why not just go for it I know an entire paragraph and I pretty much said nothing to help ha ha good luck bud. Great progress. Let’s keep it up. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562373 Share on other sites More sharing options...

Wow that sounds really handy.Taking them out of a Hino double drive is a lot more involved than that...but then when I was doing them it was for full rebuilds so if your not taking them apart then thats the way to go...

MACKS Posted 18 hours ago Share Posted 18 hours ago Yup torque rods to but what 10.5 locking nut,I’m talking about the. Trunnion caps under the truck not the ones on the ends of the bar, probably a better word for the ones I’m talking about..

hicrop10 Posted 17 hours ago Author Share Posted 17 hours ago The a frames stay attached to the bogies.I’m not talking about taking the leaf springs apart,once I remove the bogies I will be able to get everything blasted and painted.

Mark T Posted 16 hours ago Share Posted 16 hours ago I'd be real surprised if that frame sprung an eighth of an inch. Looks like the angles for the fifth wheel and rear crossmember and the end plates welded on the back would have to come off. Then slide it all out the back in one piece. All I can picture in my head right now is the Proctor truck.

hicrop10 Posted 12 hours ago Author Share Posted 12 hours ago Well I’m going for it.Breaking out the 1” airgun,if that doesn’t do it I’ll add a little heat to the nuts and hopefully they come off.

1961H67 Posted 11 hours ago Share Posted 11 hours ago It will make a more detailed job, plus you can get the sand out of all the hidden areas. Paint it separate and throw you some new bolts in it when you reassemble , that’s the icing on the cake. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562399 Share on other sites More sharing options...
mattb73lt Posted 8 hours ago Share Posted 8 hours ago I removed a set of tandems from my B73 when I got it to bring it back to a single axle. It wasn’t too hard to do and I don’t have a lot of heavy equipment. It sounds like you’re going to do it. Since you’re digging that deep it may be worth removing the inner frame support. That way you can get at any rust between the frame rails. It may take some extra cutting and then rewelding, but it could be worth it. I help scrap two B63’s years ago with 58K rears and I can tell you they weigh about 7,000#’s without rims and tires. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562401 Share on other sites More sharing options...
hicrop10 Posted 3 hours ago Author Share Posted 3 hours ago First I’ve gotta say thanks to everyone that has responded,thank you.I’m thinking that I will pull the frame and rears out of the building then spin it around and push it back in. This way the rear of truck is right at the door, that way I can use something big to pull them out.Like mattb73lt said his 58,000’s were 7,000 lbs, mine are 65,000’s.The first thing I will try today is to try and loosen them up,with some heat and the 1” airgun.If they don’t come loose I may just bag it.Tks again look forward for the pictures. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562403 Share on other sites More sharing options...
cruiseliner64 Posted 3 hours ago Share Posted 3 hours ago (edited) If your going new bolts and the old ones dont dont come off.. the Irish answer is the hot spanner.....Cut.I would always replace bolts that have been rusted together..if I can get new ones that is...

terry Posted 3 hours ago Share Posted 3 hours ago They are probably body bound bolts, which can be even harder to get out. Terry 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562405 Share on other sites More sharing options...
JoeH Posted 2 hours ago Share Posted 2 hours ago On this setup I believe the crossmember inside the tandem unbolts I have a truck with this setup, but I've never pulled it apart. Trunnion bar underneath has bolt on caps underneath, so depending on what you're trying to accomplish you probably have a few options. You could unbolts the trunnion bar caps and lift the truck off the suspension/tears. Whatever you're thinking it requires lots of room and big toys to get this job done, everything is heavy!!! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562408 Share on other sites More sharing options...

That’s the way I would go,then remove fifth wheel and plate should be plenty of room to sand blast and paint,chances are the trunnion caps and bolts will need replace anyway.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74779-separate-the-frame-and-bogies/#findComment-562412 Share on other sites More sharing options...
