Procedure for replacing friction disk bearings for Husqvarna 450x 430 450 and others.
Bearings are 6800RS
10mmx19mmx5mm
two bearings are required.
Here is what I learned. I initially got the 6800ZZ bearings thinking that would suffice, but they got wet and moisture got inside and they failed within a coupe weeks. The ZZ are shielded from debris but not moisture. The "RS" are rubber seal.
