Can a rusty spacer be treated?

[Commuter_Tim]

I keep having to remove my rear spacer to scrub it, but it goes orange with rust about every 2 weeks outside, the spacer other side is fine.

I even tried coating it in acf50 and drying, then fitting, it helped only a little.
Is there a cure or do spacers just need replacing when they corrode?

The rust will only come back with a vengeance as you have found out. The only way to keep it rust free would be to paint it.

Personally I wouldn't bother.

Hi

You could get it replated. Although probably only makes sense as part of a batch of bits to get done

All the best

Heat it up and quench it in oil it should give it some protection.

What bike and year? Probably costs about £3 to replace.

You could be a flash git and get a titanium replacement.

'Emery paper' the corrosion off then spray can it if it bothers you that much.

Smear a bit of grease on it!
Do you grease the axle at all?
Every spacer I've ever had, had a good coating of caked on grease on it!

Aesthetics rarely bother me with bikes, but I assumed at minimum it would probably eat at the seals?
That being said, at the cost I may just purchase a spare set of dust seals.

I did think of painting it too, but I assumed that with the small amount of space between it and the seal, the paint would bind it?

Once rusty again, treat with Kurust (or any chromic acid based rust treatment). It works by turning the iron oxide into a hard, impervious [black] layer which prevents further corrosion. You can buy it in Halfords, I've had a tub in my garage for at least 15 years and it still works fine.

I do grease the spindle, but I didn't think of greasing the outside of the spacer, with it being so close to the disc.

Just general purpose grease or copper?

I use zinc spray whenever I'm doing something in mild steel that I won't get a chance to paint.

Take spacer off, clean it, put a blob of grease on it, (any grease will do), work the grease around with your hand, wipe off excess, replace.
The thin layer you apply will not fling off.

Can't believe some of the replies in this thread, spray it with this, coat it with that, buy a new one, FFS, talk about overthinking a very minor problem.
Apart from anything else a coating of grease in that particular area, will help prevent assorted crud finding its way into the bearings.

Grease it with lithium grease. That said. It's probably not doing any harm apart from looking unsightly. If it was rubbing against anything, it wouldn't be going rusty!

Don't worry about getting grease on your rear disc by the way. even if you cake that spacer in grease it's not going to find it's way onto the disc unless you put it there.

I suspect the reason my CB250RS only got a rosette at a classic show was because I used grease on my spacer.

Cheers all, greased her up good and proper today.
I meant to do it earlier but got distracted by an orange brake piston, arguably more deathly.
