I searched the board for galvanic corrosion, but nothing on the Polaris. My wheel axles kept snapping off, so I went to do a rebuild. When taking the unit apart, the grommets in the frame for the front drive axle have pulled out making the frame now useless.
OK, here is the issue. When rebuilding I noticed they use two different metals to bolt on the pieces in the Polaris 280. Corrosion is everywhere the two metals meet, just the grommets.
The grommets in the frame seem to be of a copper origin or brass? However, the bolts are all stainless steel. Flaw or conceived, the two different metals seem to corrode. My unit is only one year old.
I researched this and found "proof" http://www.corrosionist.com/Galvanic_Corrosion.htm. All it takes is two different metals bolted together and any kind of water except distilled water to cause the corrosion. Salted water must make it worse?
Also, the drive shaft just rusts away and this must also be designed this way so it must be replaced.
I was thinking that I cannot be the only one to notice this?
