Casale Failure???

[shirkey4750]

Took the V-drive apart, and this is what I found. Been together for two summers. Case ran cool at all times with Redline 70-90. Had noticed a little higher howl than usual toward the end of the season last year, was one of the reasons that it was taken apart, plus to change oil. Anyone have any idea what could have happened? Was set up with a .007 lash in the gears.

I can't read them but maybe 12 deg gears in a 10 deg case?

I posted on your other thread in gear heads. :)

yeah that would probably do it too.

[Sangster]

What do you want for the Gears.........:D :D :D

[superdave013]

Flip those gears around so we can see the numbers that are stamped in them.
I'm just wondering how old they are. And like sangster said. Are they 12 degree gears in a 10 degree box?
They could be 30+ years old and one tooth just let go and took out the others.
I would put that in a box and ship it to V Drive Tom or Looking For Liquid (or someone like like them) to make it's set up correct.

hey that was me, I need some fittings, I'll make a list

[shirkey4750]

Gears are 10 deg., cases are 10 deg.

Well those are no spring chickens. They were made in July of 1970. They lasted just a few months short of 34 years. Most outdrive gears that get some power socked to them don't even last one season.

Opps, yeah that was you. Shoot me a list and I'll fix you up. I have hose too.

[CircleJerk]

Those look like 12 degree gears to me! Whats the box number?:eek: if there are no degree designation then they are 12s, I dont see a 10 degree marking..........Is this right Tom?

[beaverfab]

We had the same problem on a Pro Mod boat the problem is your v drive plate is flexing. Yo need to run stronger braces. The top one as high as you can. Thers is a set on e bay now 2475031523, look at that one . I like thr top[ brace even higher. jj. Give me a call if you need more info. 972-438-2277. day 7:00an to 3:30 pm Centeral time.:)

Good catch CJ. I just lightend up the pic in photo shop. No 10 degree stamp that I can see.

[CircleJerk]

Can you lighten up my bread basket? Hey, I blew more teeth off my Barrons gears AND cracked the case, does that mean I had more horsepower?:D Thanks for clueing me in on the date code! I will see if I can find older ones...........

Yes CJ, I will take all of your bread. You can even send it to me in the form of a personal check but I'ed rather have a money order or CASH! :D

[shirkey4750]

Lets see if we can clear up the 10 or 12 deg. problem, the darker colored gear with the rust is marked 12 deg.

[superdave013]

well that would be the very first set out of the hundreds that have I've seen go through my exchange program that is 10 degree with out it stamped as so. Now I'm not sayin you are wrong. Just that is the first set I've seen. I guess from now on I'll measure EVERY set's angle if it's not stamped. I'm still learning too and just learned that today.
So we are back to the fact that that was a 34 year old set of gears. How long are they supposed to last? I still say many different people got their moneys worth out of that set.
How do your shafts look? I guess it's hard to say how the bearings were as they had to have been damaged by all the chunks floating around.
You are lucky the gears stayed inside the cases. Could you imagin 12 pounds of gears comming out of that case at a high rpm? Would be ugly. I know a guy who has a chunk out of his calf from that happing.

[CircleJerk]

So is Schiada96 right? Those were 12s in a 10 box? I'm confused.......

[shirkey4750]

Dave, the bearings were all sealed bearings except for the bearing in front of the in-out box, and it seems to be seems to roll very smooth, but it will be changed out. Maybe the problem is the flexing. as this boat is used as a river hydro and it sees some rough water which is ridden through at throttle with the nose up. Now I have to figure out what gears to put back and keep it from happening again. Want to think everyone for their input on this problem and keep the suggestions coming.

[V-Drive Tom]

IF a Casale gear set is not stamped with Degree #, Then they are 12 degree gears.
The reason is because the 12 degree v-drive came first.
They didn't make a 10 degree until later. So no need to stamp degree in gear.
When you put 12 degree gears in a 10 degree box the teeth are only engaging by about 1/2 of the tooth width. It will work but you don't have the strength of the entire tooth width. They engage on the back side of each gear. Right where you lost your teeth. :(
NEVER put 10 degree gears in a 12 degree box. All of the load will be on the front of the teeth and they WILL destroy themselves!
TOM..:)

[shirkey4750]

Thanks Tom, this has been an education in V-drives for me and hopefully for some others. May contact you about setting this V-drive back up.

[shirkey4750]

Getting ready to put the V drive back together, and want to confirm some numbers. The case is a 61000-1 which is a 10 deg box correct? The old box which was broken was a 62500-1 which is a 12 deg. correct. But the 62500 was stamped 10 deg., which the old 22% gears came out of, and that was why I assumed the old gears were 10 deg. Also does anyone have the manufactor and number for the case bearings, I can buy them through the company that I work for at a big discount.

I bought my bearings from Tom at Menkens. Not only did he make sure I had the right stuff, but he also made sure that I set it up correctly when I went back together with it and the prices were damn fair as well. The expertise he shared with me through my set up to make sure it was right and SAFE was worth a lot more than what he made off the bearings and spacers I bought from him. If you use him make sure you are standing over your v-drive when you call him, it makes your order go a little easier and you can confirm shaft sizes and such to make sure you get the correct bearings and seals.
Just my .02.:)

I thought you could run 10 deg gears in a 12 deg box. But not 12 deg gears in a 10 deg box???

[Rusty Knutts]

thats like wearing shoes that are to small and on the wrong foot! And trying to run the Boston Marathon!

Either way it don't matter, you're still not matched!..
