Eric's Supercharged Shit-box

Why would you assume we would leave it dirty and painted before welding?

It's not our first time welding..

I doubt it would be a 100x better.

And I wanted a lower mount like how you have it but it just wasn't working. Woulda be great if the Tcase was clocked. But it wasn't. So the front drive output was a major issue.

It's not perfect but it'll hold just fine. Not sure what has your panties in such a twist about it. It was a simple solution that Jon came up with and it came together just fine.

Hopefully Eric will consider clocking the tcase or adding dual cases. Then it can be re addressed.

 

Monte what kind of camera are you using? thats the clearest pics I've ever seen.

 

Thanks man.

I shoot a canon 60D and used my 10-18mm STM lens for most the photos. Edited them in Lightroom.

They turned out great that's for sure!

 

No problem. I think it should be addressed for sure. I've seen race trucks actually hard mount engines AND transfer cases to the chassis before but never seen anything like this.

You're getting more defensive over the t-case mount than the guy who fabricated it. You sure that was Jons idea and Jons welds? LOL

 

I'm not definitive about the fab work. I'm more upset by the fact you're up in arms about solid mounts which it would appear you don't toally know about.

Solid mounting is totally fine. It just induces vibrations, but you'll only ever feel them at idle maybe.

The part where solid mounting is bad is if you only solid mount one part of the drive train, like in your case, just the motor but not the tranny. This means the motor will barely move but the tranny still moves a lot. This puts stress on the actualy bellhousing and input shaft which isn't good.

Basically if you want to solid mount, you need go all in or not at all. You should never do half and half.

As for the welds, the only things I welded where the bump stop mounts and bump plates, some d rings and the top of the link brackets. Jon did the rest. He is better at it then I am. Much more practiced and more recently practiced. I mostly just cut the pieces. Jon is a great welder...just..Gravity is a bitch haha

So there haha

 

If there's one thing I can't stand about welding, it's when I can't see shit!!

 

I'm seriously thinking about getting some of these

His motor has bushings, the transfer case does not. How does it get more clear than that? Shitty Trail Gear bushings doesn't count as solid mounting LOL I know exactly how "solid" mounting works. Hard mount, use poly bushings or stock bushings but the style of mount has to be the same at both ends.

Also, there is 1/4"x3" steel plate controlling all the drivetrain twist. I'm very interested to see how well that holds up

 

From the consensus (IIRC), bushing type (or lack thereof) should be the same for both motor and transmission. That was about the extent of it.

But what about the mount itself? Location and weight distribution? Even if the bushings are the same type... on the axis from center, the mounts at the engine are under more stress from weight in addition to generally being positioned farther to the sides (eg. 4 and 8'oclock) and father distance from center than what you would find under the transmission.

One would assume that based on factors like this, the harmonics/torsional stresses between the two would be different regardless if you have the same bushing material. If whether the differences are negligible or if you could even find a mount material/position that would reduces the gap in those differences... I haven't a fuckin clue.

 

They are nice!! Need me a Monte all the time to take photos

Thanks man!

Do it

We discussed this several times... I don't get the cool up travel all the folks running mid steer do. I left the ram in the position I had it for when I was leaf sprung which was over the leafs for hi-steer. Due to limited time, I didn't want to put more work in the D44 for 2" extra uptravel which I've never had and I've wheeled some crazy fucking hard courses.

Along with the tranny mount, well maybe when I become cool like the rest of the world I will run dual cases or just clock my t-case, until then this is what worked.

I didn't intend for it to be permanent forever, but at least for awhile until I get dual cases/ clock the t-case.

 

Example... just because (in theory) the mount material is the same here as at the engine, I can't imagine that you are going to experience the same torsional stresses between these two trans mounting options.

 

Well, I placed an order for 14" 200# springs to replace the 100# springs. Hopefully they'll work this time.

 

I don't think there is necessarily more stress on the Trail Fail mount because it's holding up a lot less weight than the engine mounts. The motor controls MOST of the torsional stress since a lot of weight is resting on it and thats where the torque begins, having wide mounts helps a lot there. The transfer case can deal with a tighter mount because its a secondary and its holding up less weight. Think of how the stock setup was engineered. Ideally when you rev the motor, you want both mounts to give the same amount. And I can tell you from experience that having an automatic and the plate style t-case mount where the bushings are at the frame, it will rattle a lot more than bushings that are close together. I'll gladly sacrifice a little torsional control for a lot less rattling

 

Right, my point was that the torsional stresses are not going to be the same front and back, so simply having the same bushing material isn't going to be the solution.

What I don't understand is why for some reason the aforementioned styles of tcase mounting both seem perfectly acceptable to run, so long as they have the same bushing material as the engine. Clearly torsion will effect these styles differently.

I've been toying with the idea for awhile (for my truck) of running a cradle for the entire thing (front of the engine to the tcase) to ensure uniform stresses along the drivetrain and the ability to mount a skid similar to what you did.

 

We're building rock crawlers, its easier to change bushings out than build an entire cradle for the drivetrain The motor mounts will control 95% of the torsional load due to how far apart they are. The plate style mount with bushings at the frame actually tears transfer cases apart. Many people crack housings or develop leaks because of the amount of rigidity in the system. It's too stiff for stock parts, shocking!

 

Nice 3 link, think you'll be able to flex as good as this guy?

 

This build sucks

 

This build does suck..

 

I forgot who's build i was in, i had to scroll to the top to check.
