Off Season Sled Pulling Mods

Or find a circuit with loose tracks :rofl:

Our tracks with fpp are like 50/50 good/shit tracks. we seem to hurt something about 50% of the time this year. but we pulled on a few other good tracks with other orgs this year. this was the last tcase, prob had 10 hooks on it.

I guess we could cut the class back to 2007 levels of 600hp 2.8 then we wouldn't break anything!

So who's machining billet cases this winter?

If anyone is, let me know!!

That would be mint. Sounds like something up Empire Diesel's alley.

Or I guess you could adapt the 07.5+ units, maybe they would hold up better?

WOW. That thing is flexing like CRAZY!!!!!!!! I have never seen a duramax T-case do that. Even looks to have the MA T-case brase.

Its the 2nd one he's done that to...
I am not at the point like some are, where 3.0 sounds appealing. But it prob wouldn't take much more breakage to start leaning that way.

 

[05_LLY]

THe only thing inside that case that broke was the gear that drives the front shaft, which casued the chain to trash the case! Of course the rear pinion broke first, shocking the tcase. The crash happens here at 5:06.

Goddam. So in reality, instead of using a higher ratio, can you have a better quality R&P set made?

That would be nice, maybe a set in the 3.20 range would be nice to if they were getting custom made!!

 

[juddski88]

I have a possible source. I am sponsored by a shop that specializes in custom gear train for industrial/aerospace applications. When is your first pull?

 

[05_LLY]

Hopin for Rudys spring pull in mid march but making it is doubtful at this point, prob be TS end of may!

 

[juddski88]

I would assume higher operation noise wont be a concern? I know that's one complaint with the yukon gear sets. But I'm thinking even stronger material like 300M?

 

[05_LLY]

no no worries about noise here. 342 would be ok too, then would only need to make rears set! let me know if its available and how much, id look into it for sure. biggest problem with the 342 is when the pinion dose break it breaks at the splines and puts the pinion gear threw the case everytime. with the slower ratios they just clean the teeth off, change them out and move on till next time! lesser of the 2 evils kinda thing im thinking!

 

[juddski88]

still shocks the rest of the line though. Just ask Rob Hall.

Finally tore engine down, here is a couple pics of the crank. It is cracked about 80% of the way through...

Ouch, that sucks for sure!

 

[baggedLB7]

You sould send those pics to fingers.

 

[Yellow Jacket]

I'll send him the crank if he wants it after I get all the Mallory or tungsten out of it...

 

[farmtrucklb7]

Could be worse!

 

[Fingers]

Is there a lot of Mallory in the first throw?
