Full Version: Carnage!
any good TV repair man with a good set of tools and lots and lots of JB Weld should have that back as good in no time 
Damn.. That's ugly.. 
Jump Grenade?
I'd like to hear the details of how that happened. What kind of car, weight, horsepower, and the situation when it broke. Do tell.
I assume that's covered under normal wear and tear warranty? 
Been there done almost that:
This was the 1st time, I was pretty rough on her:
Had it fixed. ran good for a few trips. Then I started hearing more noises.
Found this (below) which a different Trans builder says was caused from the 1st mishap (pic above). Said the previous builder missed this which caused my next $4000 repair bill.
So far I have an 2D worth the equivilant of a S4HD in a V6 2500 pound car

that looks expensive ! tim
Wow!!
i watch'd that trans come into the shop , thats crazy , is that case still under warranty ?
thats some serious damage.... what would cause that?

I gotta say it again ...NDT non destructive testing ..no way that coulda been missed ..even with fluorescent penetrant...You guys who don't test the mendi are askin for $$$$$$. my .02
i think he let off the gas to fast when the rear started to come around on him

You are right that was probably not missed it was a judgment call to use the same case.
Most of are dealers have non destructive testing capabilities.
but you don't need that when customers make puzzles out of whole units.

Seriously, what causes that?? Looks like it just exploded
Looks like some teeth came off the pinion gear, got wedged between the pinion and ring gear then spreading the case.
I'm curious too.
My 2d case is full of pits and stress risers... Never seen so many cases that crack..

2 hours of drive time?!?!?! Ok dude......WTF happened?!?!?! People have been asking for details!!! Can you please give just a couple?!?!?! Big buggy?? Little buggy??? Motor???? And last but not least.......WHAT HAPPENED?!?!?!?!
Okay, I'll say it. I gotta give some props to Mendeola for posting pictures of their product in a less than flattering condition. Regardless of how it happened or who's fault it was...Not many manufacturers would post photos of the product they produce all blown apart. 
Now with that being said. Lots of folks would like to know some specifics on what the application is and what the cause may have been?

No problem....
Ocotillo Boy wants to make sure that the trans in the pictures didn't come from a newer SCU and he needs to know what happened to the same trans that he just spend a bunch of money on.....so he can sleep tonight.
How did I do?

Hello fellow dunners,
Here at Mendeola we have been doing driveline R&R for over 30 years.
We have learned over the years how to read Gears,bearings and failed components.
Within the last few years we have seen listed below circumstances:
Hp-exceeds the driveline capabilities
Torque-exceeds the driveline capabilities
Tires-exceeds the driveline capabilities
Inexperienced Driver-exceeds the driveline capabilities
Wrong gearbox for car
Fatigued chassis- safety issue
Improper shifter adjustment
overall platform of the car set up wrong
and the list goes on.
We at Mendeola have taken it upon ourselves to offer a new service that will extend beyond are driveline capabilities to you are customers and fellow dunners.
Below is a program we have created to help those that feel they have a specific driveline problem whether our driveline or some other brand, or would just like to have a maintenance check of there car.Please feel free to call or PM us with your needs.

Which one I can explain them all, there more pieces to the puzzle then the case.
Yes, cause no one ever showed them what they needed to know.
Sorry, i cant figure out what you said? I was only inquiring as to what happened to the case and gears? There were a few others asking the same question about what happened? Not sure why your getting so defensive?
Just my 2 Cents
Looks like some one liked to side step the clutch and do a bunch of wheelies I've seen this before when I work at Extreme Performance, we had a couple of customers that would really abuse the car not knowing the damage you could do to the trans axle.

Sorry, about that
The case & gear went boom! due to leaving his foot in the throttle while in the air causing a power reversal which blows a tooth off the ring and then he drives the car back to camp and runs that flak through the gearbox.
He did know he screwed up.
Here is the story:
2100lbs car
4 seater
35 STU's
510 LS motor
customer is a older bike rider and new to having a sand car
has 14 hrs on the car in Glamis
likes the tight bowels and uses 2nd gear exclusively for dunning
The gear stack is in new shape and only problem is the case has a crack or two.
Why?
Here is our read.
The case is cracked = something is trying to exit the case?
What is trying to exit the case? = the ring gear
Why is the ring gear trying to exit the case?= Some form of load towards the cracked side of the case.
The read on the pinion gear and ring gear tells the story.
The ring and pinion gear both have a drive and coast side to them.
The drive side is the side we load when under power.
The coast side is the side opposite the drive side we use when off the power or freewheeling.
If we look close there are deep impressions on the root of the gear on the cost side of the ring gear, and sharp edges on the top edge of the coast of the pinion gear.
How does this happen?
This happens by driving on the coast side of the ring and pinion.
Well how does this happen?
1) deceleration in to a corner also known as compression braking.
2) loading the car in drive motion and then unloading by removing acceleration.
3) removing the tires from the ground and recontacting the tires back to the ground.
So what happened?
almost 89% of the time it is #3 it has the greatest wear factor on a driveline.
the other 11% are #1 & #2 and are least likely to cause the wear we see here.
How do we alleviate this?
Know that a cure for this is to not make mistakes when driving, which takes repetition meaning you have to do this and screw up repetitively.
Very unrealistic.
#1 can be used but sparingly and @ the right time but we do have these things called brakes try them we paid a lot for them to be on our buggies.
#2 try and be smooth on the accelerator and use clutch and brake together to coast. Newbees its alright to uncertain of the terrain. Experienced drivers no more erratic throttle steering because now you know what it can cause.
#3 the first idea of #3 is whoops but whoops are not bad. What is bad is entering whoops and doing item #2 this is do to the commitment usually,or suspension was never correct. I tell guys that once you commit to whoops stay committed. Its the old when in doubt apply GAS theory.
So what is #3 about?
Its about jumping your ?+ Lbs car and landing with the throttle open. this tends to be destructive on the drive line.
There are 2 ways to correct this matter:
1) match your tire speed to ground speed when re-entering the ground. this is for the professionals and a hard calculation to do. (Robbie Gordon Sh*t)
2) easiest and most over looked is put in the clutch. this will disengage the motor from the driveline.
So, why does this happen?
Power load reversal.
A power load reversal is when the tires (take the size) come back to earth and momentarily drive backwards due to change in speed. this backwards rotation travels up through the tire to the Cv,axle,Cv, into gearbox first hitting the Planetary gears then the differential and then ring gear and pinion.
Meanwhile the engine is moving through its RPM through the crank, clutch, entering the gearbox at the inputshaft to the gear it was last in down to the pinion gear.
The ring and pinion does 100% duty cycle which means it runs forward, or backwards in which ever gear you choose except when you are stopped or the clutch is in.
I tell you this because this is where the shock will impact when forward motion meets with reverse motion in this system.
This Kind of shock is what causes this destruction to below shown gearbox.
The simplest way to avoid this is to put the clutch pedal in, thus disengaging the system allowing it to freewheel.
With this customer we have offered him a deal on a case and a deal on building and re-gearing it.
He claims that no one ever told him this.
