How To Repair Bike Pump
When it comes to repairing and maintaining your bike—with brakes, derailleurs, cables, and more than—the checklist can seem endless. Only there'south one other crucial, though frequently disregarded, chemical element that's arguably just as important to treat in society to go on your bike rolling: your floor pump.
Sure, your floor pump will kick the saucepan eventually. But if a part breaks or isn't working quite as well every bit it used to, chances are you'll be able to gear up it.

"In my time in shops, I accept given many pumps a 2d life," says Bicycling's resident mechanic Joël Nankman, who's wrenched professionally for thirteen years. When a customer would come up into the shop to buy a new bike pump, Nankman says that sometimes he could simply set up their old i instead.
Many of the repairs and maintenance measures are like shooting fish in a barrel enough for almost people to exercise on their own. So when y'all find yourself with a flooring pump that's failing, don't toss information technology just yet—you might just be able to return it to its former celebrity. (Plus, it's the eco-friendly matter to do, correct?)
Below, Nankman offers his tips on how to repair and maintain your bike flooring pump.
Preventative Maintenance for Floor Pumps
To start, there are some things you can do to aid prevent your flooring pump from breaking in the kickoff identify—namely, storing it correctly. Hither'due south what Nankman recommends:
Keep It Dry out
You wouldn't leave your bike out in the rain (or maybe you would, but here's why y'all shouldn't), and the aforementioned goes for your floor pump. Store your floor pump somewhere out of the elements and abroad from wet that could potentially damage it.
Mind the Temperature
I, too, am guilty of chucking my bike pump in the car and leaving it there, well, indefinitely. While information technology might be convenient to e'er accept one at the trailhead or commencement of the group ride, exposing the pump to a wide range of fluctuating temperatures can damage it over time, especially the pressure gauge.
Common Bike Pump Repairs
Nankman says that, generally, the more money you spend on a bike pump, the meliorate its quality and longevity—though that rule isn't firm and sometimes the most affordable flooring pumps tin can outperform expectations.
According to Nankman, these are the most common parts that will break or require maintenance on a flooring pump: the pump head, the air hose, the force per unit area guess, and the main seal (or gasket).
"Depending on the pump, all of those are replaceable," he says. "Typically, as a pump goes upward in price, the more parts are replaceable and available to supplant."
Brands such as Lezyne, Park Tool, Specialized, Bontrager, Silca, Topeak, and more offer replacement parts and rebuild kits for floor pumps. Cheque with the manufacturer to see if that'south the instance for yours. If not, you might however be able to fix information technology. O-rings in particular, which maintain the air seal throughout the pump, tin can exist readily found in a variety of sizes.
"Very often parts are cross-compatible," Nankman says, simply you'd either need to know that for sure earlier buying them or happen to already have those parts on paw to experiment. When in doubt, contact the manufacturer to see if replacement parts are available, or visit your local wheel store to see if the mechanics can assistance you gear up it.
Pump Head and Air Hose
It might seem obvious that in order to prolong the life of your floor pump, y'all need to use it correctly. Specifically, you need to fit the head properly onto the valve. "Make certain yous put the pump head on the valve directly and make certain it is seated," Nankman says. (Also, make sure you're using the right valve caput: Here's the departure between a Presta valve and a Schrader valve.)
Depending on the kind of floor pump you have, you might exist able to replace the unabridged pump head or the o-rings that go inside information technology that create a secure seal. Similarly, information technology'southward piece of cake to install a new hose; you can often find either the replacement hose or both the hose and pump head together. To install both, simply unscrew the threaded cap at the end and pull the hose or head off the fitting.
Main Seal
Similar the many moving components on your cycle, your floor pump parts also crave periodic lubrication, specifically the main seal at the finish of the plunger. "The master seal—likewise called the plunger [gasket] or main gasket—is essentially the seal that you are pushing downward and pulling upwards to produce air," Nankman says.
If the pumping action feels gritty, sounds noisy, or gives resistance, yous probable demand to lubricate the chief seal. Nankman recommends doing it at least once a yr, or more frequently if the pump is exposed to dry, dusty conditions. Standard bike grease will exercise the job, or you could employ Nankman's go-to, WD-40 Specialist Silicone spray. Simply if your pump's plunger uses a leather gasket instead of a rubber i, you'll need a specific lubricant, like Silca'due south NFS Leather Conditioner.
Restore Your Floor Pump
"If using grease, you lot need to take the top cap off the pump to expose the plunger. Pull the plunger out of the pump tube. Utilise a lilliputian bit of grease to the plunger and reassemble," Nankman says. "If using a liquid silicone lubricant, [utilise] a good spray on the pump shaft, and and so pump upward and down a few times to go the lube to get everywhere in the pump."
Force per unit area Gauge
Over time, your flooring pump's pressure estimate tin can kickoff to deteriorate, making it less accurate.
"Accuracy is the principal [trouble], but that is hard to quantify unless yous become a new pump and compare information technology. I tend to recommend that people become a stand-alone pressure estimate anyway," Nankman says, which you lot tin use to test the accuracy of your pump'southward pressure approximate. "They are inexpensive. I keep one in each vehicle, and a few around the house."
Follow the manufacturer's instructions on how to swap in a new gauge, though almost are fairly straightforward; you'll remove the pressure gauge embrace by either unscrewing it or prying it off.
So, Just How Long Tin a Bike Pump Last?
Well, that depends on the quality of its construction, how well y'all care for it, and the availability of replacement parts over time.
Nankman has his granddad's German-fabricated SKS RennKompressor floor pump—it'southward almost 50 years sometime and it withal works (though he admits he uses it sparingly). "I accept changed the caput once and the leather seal a handful of times," he says.
