843 drive chains

[Dgreen4298]

I need new drive chains for my 843, they are stretched out and rubbing the reduction gear housing. the dealer wants $220 each for them for a total of $880 . anyone know of a cheaper option that is not made in china? can you tell me how to find out what size chains they are?

Service manual says they are ANSI 100HS chains. Any power transmission supplier should be able to get it.
Diamond, US Tsubaki and Timken all make their chain in the USA.

Check the sprockets for wear also.
