Welcome to the forum. Not sure what schtack sounds like

 

It’s a slippery sound.

 

Post a video up on youtube then put the link up here.

 

Good idea. I’ll do it.

 

On Utube search for : the schtack sound

 

Or Yamaha Viking schtack sound

 

Copy and paste the youtube link here is the easiest way for us to get to it.

 

Are you referring to the quick bang sound at the very end of the video?

 

Yes exactly.

 

Are you in Low or high gear when this happens?
My Viking makes that exact sound every time when I put it in Low gear and then start moving forward. It is the linkage fully engaging into Low once I start moving a little. It has always done it since new so I figured it was normal and it has never been a problem.
So that maybe what’s happening with your Viking if you’re in Low gear, but that is a very long time for it to happen. If this is what’s happening you’re probably going to have to look at getting it all adjusted better.

Thank you for your comments. It happens when I am in High gear moving down a slope. Never when I move forward.

 

I have tried it in low gear and no sound….

 

Is it a SCHTACK!!!!!!!!!!!!!! ? or is it sssssssssschtaaaaaaaack? Or maybe sch sch sch tack?

mine is more of a schtacka-schtacka-schtacka

 

No it’s is really an »schtak » and following an observation from one member of this forum, I have tried going down a 30degrees slope at low gear and I did not hear the schtack sound. It only happened when I am at high gear.

 

Middle gear bolts lloose. Gravity pulls them into the pinion. Speedometer working ok when this happens? I would not drive it until you inspect it.

 

Good point… absolutely watch the speedometer when you take your foot off the gas, if it goes to zero while still moving you have middle gear coming loose. You don’t need to be going down hill to check this.
