Replace Aluminum Screws with Stainless Steel?
Posted: Sun Oct 24, 2021 6:43 pm
Hi guys.
I am tearing down my newly rediscovered YZ10. As I do it I noticed that most, if not all, of the screws going into the front and rear magnesium bulkheads are Aluminum. Interesting choice but I would rather just replace all of them with Stainless Steel which would be more durable (most of the aluminum screws are stripped to varying extents).
But I am wondering why they would use Al as the material in the first place. Is it purely for weight? Seems kind of silly, cant image it making that much of a difference.
Or is it because Steel screws can react with the magnesium. I didnt think it would especially since the main bearing for the differential are stainless but figured I would check first. What really gave me concern is that the rods holding in the lower A-Arms (looks like steel) are actually seized up with the bulkheads when trying to pull them out.
