TRS weak cases?
 

I have gone through 2 try's in 15 hours one set of lower gears were brand new, I am pushing big power for a TRS but the last RH went 2 seasons of extremes a use no failures .... So I am wondering now how many failures can these cases take? I seriously think there is a case issue helping mine die so fast now I don't have corrosion but had at least 2 explosions inside that I know of who knows how many before that.... Is there a point where it just won't hold anymore?

I am well state of all the issues with bigger power and TRS but should last longer then 14 hours

Who's building them?

My buddy Scott he's been doing them for many years never had issues like we're having all the sudden

How many times has the thought of moving up to 3A's crossed your mind? From what I hear the transom cut out is larger on the SSM 3A's so that is not an issue. I think really the only big issue for us TRS guys is the trans tailstock (other than the cost of the drives and props)

Oh it's in the plans for future, but gonna be at least 2 seasons away, I had more power in old engines as far as TQ goes, I beat the drives never had issue, until n ow... I wonder if there is crack inside case allowing flex maybe? or just weak? or just bad gears, who knows some live some don't..

Your setup is like putting a 14-71 blower on a 2 bolt main 330 engine, and wondering why the crank snapped.

TRS +650hp+heavy hull+rough water+aggressive driver = broken drives. Lol

You`re in denial! 1" prop shaft, nuff said.

What is the weakest part of the drive? I can't remember anymore..

Hahah wtf was I thinking? Oh well guess I need more spares!!! I have no idea how the last ones went 2 seasons of abuse

Lower gears and on a right hand pushes against the carrier the left pushes into the case...

This might sound crazy but could the cases be tweaked and fatigued from failures and hours of running?

Thaysbwhatbi am thinking, or just a set of gears let go that just happens too I guess

What gear oil do you run in them?

I have ran valvoline 80w90 for years.

for me it was the lowers vertical shaft,,I'd snap those things like nothing and in turn would window the lower case.

how are the lower gears dying?Can you post a pic.almost sounds like a set up problem but then after that,something could be moving in the case to lose the back lash and bearing preload.

Arneson and never look back.

Didn't take it apart yet but it's not setup, my buddy knows these drives been doing them for years never had issues, really thinking its a case issue but could just be bad luck too

text me a pic of the last set of gears..i would like to see the contact pattern..

by feeling it there will not be one like the last set that totally exploded.....

Bingo.... we used to do a ton of trs stuff , once a case has seen a blow-up of the lower gears the case gets stretched and the new gears will never last like they did in a new case.. The only real way to make them live is to change the gear sets out before they blow-up and ruin the case..

Are these new gear sets?

Yes new gears.

Case had at least 2 other fails I know of so 3 total... Scott and I both think it's case related at this point

Add nose cones, that will fix it Tim:flag::wizard:

Yes!! Haha

Problem is that after Mercury Dropped the TRS line and about 4 years after that, they started to outsource the gear sets to CHINA and the quality of the gears were poor and the specs along with the Rockwell Hardness were not on par with the original Spec'd Merc Gears. So if you have the opportunity to find sets that were sitting on a shelf for 20 years, they are better then the later versions. Just my 2 cents on experience. Sometimes you can find originals, it took me a long time to find a couple sets, I think I got them from Mel Riggs, but that was 10 years ago......the box was dusty then......lol

the ones I had were in very old boxes also, for sure been sitting but no way would I know China or merc they seemed merc to me lol

I'd probably have the case magnaflux texted on the bearing races and/or a liquid penetrant test to see if there's any cracks anywhere...

Or maybe just stop driving like an a$$$hole..lol

Hah!!!

But.... Wait... But.... Yaaaaa you got a good point lol

I have new t.r.s.cases in the box 500.
00 each

you need a cig with #3's, stop being cheap, being cheap costs you more in the long run, so lube up that squeeking ass and get what you need :)

yes I am so cheap I spent 34,000.00 last winter LOL

I need to do other things before swapping to 3's I have a home that needs attention that was deal with wife, mot many wives let a guy spend that kinda money and not say a word, for now TRS needs to be ok, they should last longer then 10 hours though, left has been fine the spare right has been ok so far but have not been killing it either....

how many?

Have 6 for sale

I need new trs cases etc .

My wife is ok with it thats why she is a keeper lol......buy boat 60k ( loan not daddy) beat the snot out of new toy for one summer. Find out I broke chit 20k for motor and drive work... (all of r savings not daddy) and she is still around lol like I sead keeper
