Idea's on removing rust on shaft final drive.

[Krunk_Kracker]

My bike is coming along, but the output shaft on my bike has a lot of rust on it. I don't want to disassemble the bike so I wanted to know what everyone thought would be the best course of action to remove it.

Is there something like a spray on rust remover that I can hit it with?

What if I was to hit it real hard with a wire brush and then use the primer that goes over rusts and neutralizes it?

Is there anything else that would work better?

Por-15 paint, followed by a top coat of some sort. Good stuff.

BTW, that rust most likely started because the battery puked. Always make sure your battery drain tube is attached and routed out of harms way.

Thank you! I'll look into that.

I've never even thought to check the tube, I'll do that, although I'll be switching to one of those really small batteries really soon.

Naval Jelly is great at removing rust, and leaves behind a rust resistant flat black oxide.

I'd apply it to the affected area, then hose it off after an hour or two. You could prime and paint it if you want to, or leave it as is, and nobody would really notice it unless they were closely examining the bike.

I recently bought some Evaporust from Harbor Freight (not their brand, but they sell it there), and it is AWESOME! The challenge for you, however, is that Evaporust (and products like it) work best when you bathe the part in it for 30 minutes to overnight (depending on how bad the rust is). I have had success, however, using it in combination with a wire brush. I did the inside of my badly corroded hitch receiver on my truck, and it worked great!

The wire brush takes care of the major scale and the Evaporust then chemically removes all the rust in the pits and scratches that the wire brush can't reach. When finished, rinse the residue off with water (ironically), and then dry it quickly before spraying on a primer/paint. You'll be good to go, with no micro-rust spots starting the rot up again from the inside.

The best part is that unlike acid-based rust removers this stuff is harmless to everything except rust. You don't even need to wear gloves to use it, and it really works! There are several similar products now available, and I believe they all work very well, though I haven't tried any others personally.

I like Evaporust,don't like the 30 bucks a gallon it now goes for though.
White vinegar was mentioned on this site,if you can soak the item,works well.

That's why I like buying it from Harbor Freight. With discount coupons I was able to lower the price by 20-30%. Expensive stuff, but works great!
