YS624T - Grinding Noise

[Dixon]

Yamaha Snowblower Fan Club - I need some help.  My 624 has a terrible grinding noise when I put in gear and it does not move forward or backward.  I suspect the problem is the drive gear near the tred.  Has anyone had this problem before?  I have a copy of a service mannual, but I don't have a parts mannual.  Help??

Thanks,

Did you see this earlier post? It might be the reduction gear in your transmission.  I spoke with a guy from York Maine that paid his dealer $200 to replace the part.  Then he sold the snowblower on Craigslist.



There's one owner that drilled the side of his gearbox and inserted a zerk grease fitting.  There's a small gear that gets starved for grease and wears out.
