Rust spots, now what?
Postby stryker84 » Mon Apr 02, 2007 3:30 pm
that was helpful, but lately i've noticed a few spots of rust on the chain (buckets of rain recently, autumn's hit us with a vengeance here in Melbourne), and was wondering, what exactly do i do about that? was thinking WD-40 it off, and re-lube it? or is WD-40 bad for chains? what do i do bout the rusty bits?
assume i'm completely ignorant of maintaining a bike, cos (apart from what's in that thread), I AM.

WD40 would hang around in all the critical crevices to degrease any lube you put on.pugsly wrote:argh!
So what should I do now that I've soaked everything?
If I were you, I'd fully degrease the chain and running gear using citrus degreaser (aided with a chain cleaner unit if you can't get the chain off), rinse with tap water, dry, and then do a proper lube.

If you bought an expensive bike, then the bits won't add up to 2x but more like 0.69x.pugsly wrote:Now I have to go spend more money on stuff for the bike.
I've easily spent twice the value of the bike (it was a cheap bike)
on associated bits. I'll wander into the LBS, tell them the error of my ways and get chain cleaner etc.
Get those chain cleaners bits off eBay and shouldn't cost you more than $25 or there abouts. Try Rebel Sports for that citrus degreaser. I once came across a batch with good discount to those LBS prices but have not had luck since. You might get lucky. In any case, a chain cleaner is a basic and useful piece of maintenance equipment. There's nothing better looking than nicely degreased chain and running gears.

But pretty much anything else is better.
Especially don't use WD40 around the bottom bracket, cranks, pedals, hubs etc.. they need proper lubrication.

Pretty crazy proposition for the rider but a bonanza for WD40's stock holders!Bnej wrote:It probably would be okay for bicycle chains as long as you don't mind applying it constantly.

I think you'll have to ask yourself how much you want to do the work yourself vs let wrench monkeys do the work for you. Do you like mucking around with mechanical things and do you mind getting your hands dirty?pugsly wrote:ok, then, whilst we're on the buying of bits to keep the treadly rolling - what other things should I have for keeping things in tip top shape - I may as well get it all at once. I've got an allen key tool that came with the bike that goes in the saddle bag, apart from that - nada.
For the very basic, I'd say that some allen keys and philips head screw drivers (multi-tool) are all you need. That pretty much allows you to adjust all the bits and change all the common bits on the bike. The next step would be in the cleaning of chains, replacing chains, remove and mounting of cassettes, and these would include what we have just talked about along with a chain breaker, a chain whip and a cassette locknut remover. At this point, you might start to consider a bicycle repair stand to make these jobs easier and not let the bike fall over in the process. This is where I stop at the moment and think where the cost-benefit ratio stops. Beyond this are wheel truing and BB replacement/service. These require more experience and additional tools. Given the infrequency of these services, I suspect it might be better to get someone to do it for you unless you are keen to have the experience.
Oh yes, I assume you already have tyre levers and tube patching kits right?

However I would add a good hammer to the list.

I've fitted an SRAM powerlink so I can R&R the chain for cleaning/lubing. I'm using a chain oil - it does tend to make the dirt stick, but it doesn't wash off in the rain.
I might try the Prolink lube again now that the rainy season appears to be over.

Since I don't have the tools yet, I think I might head to the LBS and negotiate with them to lube all the vitals, and show me how it's done, so I can do it for next time. I did all of 3km

I don't mind either so much as actually having the time to do it. I'd rather spend the hour or so I have available at whatever time riding than working on the bike. Having said that, I don't want to have to take the bike to a shop for the day, for what amounts to 10 mins of work.sogood wrote:I think you'll have to ask yourself how much you want to do the work yourself vs let wrench monkeys do the work for you.

Check. Got that stuff - it's been very handy to date.sogood wrote:For the very basic, I'd say that some allen keys and philips head screw drivers (multi-tool) are all you need. That pretty much allows you to adjust all the bits and change all the common bits on the bike.
egads! Cleaning and lubing, with the ocassional cable adjustment is probably about as far as I want to go I think, and puncture repair of course. Any more than that and I risk breaking something, and probably myself when the component I thought I fixed breaks as I'm on the bike.sogood wrote:The next step would be in the cleaning of chains, replacing chains, remove and mounting of cassettes, and these would include what we have just talked about along with a chain breaker, a chain whip and a cassette locknut remover.

Yup, sure do.sogood wrote:Oh yes, I assume you already have tyre levers and tube patching kits right?
ok, so dumb question time - I now know that wd40 and the like are no-no's as far as lubricant is concerned. I have a inkling that k-y would be no good as well what lubricant should I be getting for what bits, how should it be applied with what frequency, and where do I get the stuff?

You can get it at almost any LBS. About $17 per bottle, which should last you a while.
Cheers,
Tom

You've only just bought your bike not too long ago right? This present problem surely can be looked after under that new purchase goodwill umbrella, right?pugsly wrote:ok, so dumb question time - I now know that wd40 and the like are no-no's as far as lubricant is concerned.

There are too many brands of lube out there. Essentially there's a triangle of 3 performance parameters out of which you typically can only choose 2 with any one product. They are,
1) Lubrication quality
2) Durability especially wet resistance
3) Dirt resistance
Presently I use Weldite's spray on lube. It doesn't last well in the wet and I have to apply weekly, but it doesn't attract much dirt (ie. Relatively clean chain). But I may try Prolink next.

If you WD40'd your chain, just treat it like the instructions say to treat a new chain. Prolink displaces any grease from a new chain when you first apply it anyway, so it should displace the WD40 too. I re-lube after cleaning my bike and after riding in the rain (a whole twice in twelve months!), so the chain gets done every couple of weeks.

The rear derailleur is pretty easy to re-grease - just do one cog at a time and remember how it goes back together. If it's a Shimano, each cog just runs on a metal bush between two metal cups, it's - take a cog out of the derailleur frame, wipe off the WD40, re-grease the bushes, re-assemble and put it back in the the derailluer frame. A couple of drops of light oil on each of the joints in the main derailleur body won't hurt - just lube each joint, work the mecahanism by hand a few times, then wipe off any excess.pugsly wrote:So how about the other components, the little wheels in the derailers, the cranks, etc etc?
If there's noise from the bottom bracket, then it's probably best to let the shop do it (nothing difficult, but you need special tools to remove the cranks and get to the bottom bracket). The bottom bracket should be a sealed unit though, so it shouldn't be that.
If there's noise from the pedals, take them off (you'll need a pedal spanner) and lube them as best you can - if you dis-assemble them, they can be tricky to get back together, especially if they have loose bearings on the outer end of the pedal spindle.
Hopefully, the noise will just be chain noise as it goes around the chainrings.

The issue here is that WD40 is not grease, it's primarily a solvent and stays being a solvent. At the end of the day, the chain won't suddenly self destruct with WD40 and there are plenty of bike owners who use WD40 without knowing any better. So unless you are a purist, treat it as a learning lesson and just use other lubes over it and forget about it. Eventually the new lubes will take over from WD40. And when the chain is due for its proper clean, then make sure WD40 is not used.LuckyPierre wrote:If you WD40'd your chain, just treat it like the instructions say to treat a new chain.

Unlikely - WD40 is volatile and evaporates off anyway, and the worst case is that it will have washed dust into some of the bearings - but if they were greased properly in the first place, that shouldn't happen.pugsly wrote:So how about the other components, the little wheels in the derailers, the cranks, etc etc?
I've called the LBS - sounds like they have to pull it all apart, regrease and put together.
Unless you got totally carried away with the spray and sprayed into gaps in the rear hub and bottom bracket, I'd just wash down the bike with detergent, and then re-lube the chain.
