RS Venture: Pivot Arm 2 Weld Failure

[hondo]

Hi Jeff,

If you look at the schematic it looks like the part #43 (line) points to the weld seam. On this side of the schematic below the holes, the black line would also indicate the weld seam.

I see what you are saying Maddogjeff. I wish my camera had fresh batteries to take a picture of the separated pivot arm bracket the day I was at the dealership. I guess it is the bottom or front depending how you look at it.

It looks like aventure cut the holed flange out, made his own support bracket and bolted it in. Looks like a solid fix. Towings design looks good too.

Point is, we want to prevent the black spring blocks from separating from the pivot arm, and releasing the springs. When that happens everything goes flat. There is a "ton" of pressure on those spring blocks.

I also can see where at higher speeds the spring ends could gouge the track, or worse.

I think the the issue now is how can we ensure everyone can get an upgrade from Yamaha via a safety recall.

Maddogjeff, do you still have your skid out, and can you see any fatigue?

 

[maddogjeff]

Yeah, looked at real close last night. Don't see any problem. Have 4600 miles on it, hard, aggresive through the bumps, definitely some hard back breakers in those miles, one I hit and bottomed so hard I actually stopped and looked over the rear suspension. So far so good but you guys have me worried, if that bracket seperates at high speed or in a fast corner, it could be disastorous.

Did not cut a thing hondo....
The plate i added is just on top of the original... that's it.
I could not see a crack yet at the time i did the mod before this season.
now... 8500km.

An image is worth a thousand words... here is the original part without modification, the reds arrows pointed the welds that can break.

The brakets that me or aVenture build just bolt on the 2 screws you see on each side of the support.

The metal fatigue is really hard to see...maybe impossible just by looking at the piece. In my opinion, it's the kind of problem you better not take any chance with. Anyway, because you know it now, you won't be able to take a bump without tinking about it ..... you have no choice to do something....

O.K. I guess I'm having a tough time looking at this part.

It is a nice fix, looks real strong.

aVenture, how did you know to reinforce this piece prior to the season?

 

[hondo]

Towing,

This looks a little different from mine.

Is your sled an RS Venture TF, 156" track?

Mine is a RS Venture 144" track.

Never-the-less the same result occured, the welds failed.

Concur, no one needs to be second guessing their sled, especially with a safety issue.

This picture is the original part without any modification of my RsVenture standart 144", it is the factory desing. If you look at yours, it should be exactly the same as this picture if you don't modify it yet . This picture is for showing where the breakage occur, at the welds that the reds arrows pointed to. Is this what happen to yours Hondo ????

I just take an other picture few minutes ago of my sled with the braket installed...

And here is the braket alone before i paint it

Towing,

Yes...I was looking at mine from the side.

I have not heard from my dealer yet.

I will let you know what he says regarding the updated part numbers.

Tomorrow I will roll over 8,000 miles on the RS Venture.

 

[aVenture]

Told ya.... Towing documented the case last season on another forum but here also... just cannot find the original post anymore.... just as he reminds as a btw on another topic.

 

[maddogjeff]

Towing, thanks for the good pics.

Hondo, when you look at your new part, does it look more reinforced?

Towing or aVenture, how much would you want to fabricate your reinforcing bracket for me?

 

[aVenture]

I'd be pleased to help you on this if my garage be more metal work shop oriented. Did one, off season, then used probably 5 time the effort a pro would have taken. I guess, you will not blame me to focus on the short ongoing sled season.

Hi Guys.

This is the lastest news I have regarding this issue.

My dealer called me back today after he spoke with the Yamaha Regional Manager.

First of all let me clarify one thing: My dealer was confused with the part numbers. The 05 pivot arm number is: 8FK-47332-00-00.

The 8ES-47332-00-00 is the pivot arm shaft that goes inside. This was also replaced on my sled due to some wear.

Yamaha sent my dealer the 05 Venture part number 8FK-47332-00-00.

I looked at my sled today and it does not look any different than the old part.

The 8ET-47332-00-00 is on 06 Venture. This part has been reinforced.

Dealer said the "Gussets" which hold the spring blocks were strenghened.

This to me does not address the weld failure issue.

He said Yamaha would give me the 06 Venture Pivot Arm however, I would have to pay the labor. (about 2 hours)

I questioned him why he just didn't order an 06 Pivot Arm. He said at the time he didn't know.

I am troubled at this point. Dealer said if it fails again he would put in the 06 Pivot Arm.

What do you guys think?

My dealer still has my broken Pivot Arm. I will go the dealership, take several pictures, and post them tomorrow.

Also, thanks to aVenture and Towing for providing the great pictures. Sorry for not saying this sooner.

Thanks Guys!

That's what the forum is all about hondo.....
Can you just get the parts & install yourself then? Not such a bad job. In anycase it seems to me that you (and Towing for that matter) gets better relationship & understanding with your Dealers than i do. On my side, i did not had any chances from the dealer for that matter or others... glad the forums helped me.

 

[maddogjeff]

Thanks for the good info Hondo. I'm going to live with mine for the rest of the season and just check it after every ride. I plan to replace all my bushings and check over every part of the suspension over the summer and either get the '06 part or do some reinforcing like aVenture or Towing.
