That place good though? I trust them for chassis work a 100% they straightened and took the twist out of my R chassis that I laid over on its side at about 40mph. track better than when it was first bought. They use a Bee Line frame table. No heat, no major disassembly all laser and computer specs to check and make it factory. If you can find a shop near to you with the Bee Line system thats the best and most economical way. Sure there a shop Westchester with that machine. Here is a shot of their chassis table. 3 Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/52659-vibration-that-2-mechanics-and-mack-dealer-can%E2%80%99t-figure-out/page/13/#findComment-402179 Share on other sites More sharing options...

RobM626 Posted August 18, 2018 Author Share Posted August 18, 2018 Started back up again after a week... driving me crazy.im gonna bring it to someone to check the frame out ... 41chevy may be right. The motor and tranny may be out of alignment...it’s definately not in the motor. It has to be something with how the clutch and transmission are lining up. It changes constantly throughout the day. The clutch will go a lot softer than usual and when that happens it feels like the power/torque isn’t going to the wheels. The take off from stop also sucks when that happens and the vibration gets worst. Then all of a sudden I’ll be driving and the clutch will get nice and firm again and it feels more torquey and the clunk when I press and release accelerator doesn’t appear as much. I didn’t even wanna come back on here and say my issue started again because I’m sure all you guys were sick of hearing about it lol Quote Link to comment https://www.bigmacktrucks.com/topic/52659-vibration-that-2-mechanics-and-mack-dealer-can%E2%80%99t-figure-out/page/13/#findComment-404397 Share on other sites More sharing options...

I checked the motor mounts they looks good and tight. I gotta have a look at the bell housing bolts. They are all new . The last time I put a clutch in a couple were missing and they put all new bolts in.

Paul Yup. Before the last guy did the work it was really hard to tell, it was really looking like/sounding like a motor issue. I’m pretty certain it’s not now... every time the tranny comes out and gets lined up and tightened up and clutch adjusted properly it’s great for a few days. Once u start driving and especially putting a load on the truck the problems all start to come back at the same time...another weird thing is, my clutch goes out of adjustment soooo much faster than it ever has ( on this truck or any other truck I have ever driven) I used to b able to go a Couple years without a slight adjustment for free play. Now after a couple months I lose a lot of my free play.

Cracked chassis unnoticeable when the crack closes up OR loose chassis rail or cross member cya I have a double frame and rust started eating between the rails separating them... so much so on the back of the truck that my dump body doesn’t sit on the rails flush like they used to. I had to weld plates on the dump body rails to help shim it a little but it’s still not perfect. While driving it sounds more like a roll off carrying an empty box that’s not chained to the rails rather than a dump truck...

Maxidyne Posted August 20, 2018 Share Posted August 20, 2018 Wish we'd known that when this thread started months ago- Sounds like you may have a structurally questionable frame even before it was hit. If the frame is shifting around enough that the dump body doesn't line up with it anymore, it clearly can warp around and throw the powertrain alignment off in more ways than can be easily counted.

To be honest, every time I get under the truck to grease it and what not, I never saw the frame rust and separation past where the dump lift cylinder is.. I never thought much of it. Everything else seems tight on the truck. I’m gonna take some pictures tomorrow and post them maybe you can tell me how bad you think it looks... I know looks probably don’t mean as much as measurements do though. This is all a learning experience for me. I always thought a truck frame was STRONG. Especially a double Mack frame. I never thought these things were possible. Naive guess, or just dumb.

It seem from their posts they have vast experience in what is most likely to be your issue. But I'll bet they will tell you the same thing as most others in their business will, unless you physically put your eyes and hands on it and carefully inspect it you are only making a guess. An educated guess but still a guess. Photos will show only a small part of the story. Maybe they are close enough to look at it for you or recommend a quality shop or tech the know near you.

I was really thinking about checking out that place you recomended put in Medford. Someone else referred me to a place in the Bronx not far from me but I gotta find out a little more about them. The last thing I need is another shoemaker. Do you guys think it’s even worth fixing a rusted out frame? I keep hearing that they are going to pass a law in nyc like they did in California where you have to have an 08 or newer emissions truck. I heard it’s coming 2020. I don’t know for sure but numerous sources told me it’s happening. I feel like I’m dumping all this money into a truck I may not even be able to use for much longer Quote Link to comment https://www.bigmacktrucks.com/topic/52659-vibration-that-2-mechanics-and-mack-dealer-can%E2%80%99t-figure-out/page/13/#findComment-404559 Share on other sites More sharing options...
