Bolt question

[shade]

On my ducati I'm changing out the clutch cover.
I stepped on one of the clutch cover bolts and it broke. Its magnesium
The engine case is also magnesium
I believe I can get a stainless bolt and use that right? Stainless into magnesium should be fine?

 

[Popie]

You are right. Stainless into magnesium is fine. Just take care not to over tighten. The stainless is much harder then the magnesium.

87 inch pounds is normal on most m 6 x 1.0 bolts

Yeah it calls for 10nm.
Any help on sizing?
The ducati parts doesn't show
Its a 2019 v4 part number 77941992A
I have an Ace hardware down the street that has stainless i just don't know what size of thread pitch the bolt is. I do have the broken bolt so worst case I case use their thread finder thing

I found the sizing

 

[Popie]

When in doubt bring one of the other bolts with you. Find a nut that fits the bolt you brought. That will give you the pitch.

Use a little copper kote/anti-seize on the thread too.

Thanks all!

Anti seize won't damage any specific types of metal?

The World of Anti-Seize

Anti-seize lubricants are specialty lubricants that reduce friction between threaded and mated metal parts as well as prevent corrosion and seizure of parts under pressure and at temperatures well beyond the performance of conventional lubricants.Esse

www.crcindustries.com

"Anti-Seize is a general purpose, high temperature anti-seize lubricant for protecting metal parts against rust, corrosion, galling and seizure at temperatures to 1800° F. It is silver in color and contains copper, aluminum and graphite. Because of fine grade fillers, Silver Grade is particularly suitable for fine threaded and other closely mated parts. It is not recommended for applications where copper is prohibited."

Architecture Design Handbook: Fundamentals - Architectural Considerations

One of the most important issues concerning the use of copper is the chemical reaction between copper and other materials. Chemical reactions are responsible for corrosion, staining, and even the green patina that develops on copper surfaces over time.

www.copper.org

"Since copper has one of the highest galvanic numbers (or nobility) of the active metals, it will not be harmed by contact with any of them. It will, however, cause corrosion of the other metals if in direct contact. ... It is not necessary to isolate copper from lead, tin or stainless steel under most circumstances."
"It is not necessary to isolate copper from lead, tin or stainless steel under most circumstances. The principal metals of concern in terms of direct contact are aluminum and zinc. Iron and steel are generally not a problem unless their mass is similar or smaller than that of the copper."

As far as I know, copper and steel are compatible.
