Drive Slack?

[Daryl]

I'm having trouble with a '99 Venture 600 w/reverse. Today after backing-up and switching to forward my sled would not move, no grinding or any noises. Move lever to reverse and forward trying and nothing any way. Checked the belt and everything seemed good, then I tried turning the secondary by hand and noticed about 3 inches of free rotation back and forth, regardless of being in forward or reverse. Finally the sled started to move, drove it home, seemed ok, no weird noises or anything, but, the secondary still has that 3 inches of free rotation, that don't seem good. Any ideas, or comon problems?? I'm wondering about a broken chain tensioner? Any help would be greatly appreciated!?!

the free play is normal ...it to help align the gears when you shift it in and out of reverse.

sounds like a lot of slack. did you check chain tension yet?

 

[Daryl]

Tensioner seems plenty tight.

 

[MrSled]

it will feel like 3" at the sec but its not that much at the gear itself...

 

[Daryl]

So your thinking this is a normal amount of freeplay. Would anyone have a Yamaha with reverse that could check? I was going to open up the chain case, but, if this is comparable to other machines, then that may be suffecient reasurance. Maybe the non-movement was just the secondary being stuck open then it released closed? Thanks for all the input!

 

[MrSled]

Can you mark on your side panel or bulkhead with some chalk or something and tell me what you have on the secondary and I will verify is on my SX or RX1.

 

[Daryl]

From stop to stop 2 3/4", on the outside edge of the sheeve. Thanks for the help, I really appreciate it.

 

[MrSled]

yes that is correct I just checked mine...

 

[Daryl]

Thanks! Have you ever experienced the situation of no movement after shifting from reverse to forward? and back?

 

[MrSled]

no I have never had that happen...the linkage may be out of adjustment

the larger lower reverse gear and the small auxillary reverse gear are not meshing.... place gear lever back in original direction and budge the sled in that direction ever so slightly, the try reverse again... sled just needs to move an inch or so for the gears to mesh.....

this and the slack in secondary is very common for both our reverse equipped sleds....

tj..

yes it is usually just a case of the gears not being in position to lock together. Moving a little bit in either direction should lock them up.
