How To Repair Park Tool Floor Pump PFP-3/PFP-6 (Maintenance/Service)
Vložit
- čas přidán 28. 12. 2013
- I take apart and put together a Park Tool PFP-3 bike floor pump and show where the various o-rings are that might cause problems. I also show how to lubricate it. I include Park Tool part numbers for various parts. The Park Tool PFP-6 is pretty much the same as the PFP-3 with mostly the same parts. It will probably be cheaper to fi the old pump than to buy a new one. It just may need a new o-ring or some silicone grease.

I was thinking of mounting 2 of those pumps together. With 1 handle and at thr outlet a Y piece. So 2 outlets goung in to 1. That means doubble the pressure and 2 times as fast inflating.
I've had my pump for almost 5 years. i think its starting to show its age. being a 365 days a year commuter it gets used a lot too. i thought i was s.o.l. but i can now look into replacement parts possibly. :) thank you. worst case if i screw up I'd be buying a new pump.
You are the reason i still do my own repairs and never send it to anyone, unless its something I cant tackle and thats most of the time. I cant thank you enough.
I was about to head to buy a new pump but something got me to see if it could be repaired. With your help it was fixed in under five minutes. Much appreciated.
I disassembled my pump greased, cleaned and put back together. Was all pleased with myself until I went to use it again and it didn’t work! Was bleeding air, tyres weren’t being pumped up. I nearly lost my mind until I watched this video and realised that I had lost the little rubber ball. I found it on the floor of my living room and popped it back into the pump housing and it works now perfectly. Your video saved my sanity. 👍🏻
Brilliant. My track pump suddenly went this morning. All I had to do was open it up, wipe off the old dry grease and add new clean silica lubricate. O-ring was actually still good. Awesome, thanks.
Found this video 7 years later while looking for my Beto floor pump repair, turns out Park Tool outsourced their pump to the same factory, as it is nearly identical. Thanks RJ!
Thank you. I just fixed my pfp-6. I was going to buy a new one and it just needed to be cleaned and lubed. Saved me 30 bucks easy.
Excellent tips - and thanks so much for taking the time to ID the Park Tool part numbers
Thanks so much. You told me EXACTLY what I needed for my EXACT floor pump. You made my day, bro!
Thanks for this video. I've never taken apart a bike pump before, and this made it really easy to disassemble and reassemble with plenty of confidence.
Thanks for this tutorial, exactly what I needed. I Stripped down the head, the problem for me is with the presta part.
When the valve is inserted the pumped air sometimes doesn’t inflate the tube
It comes out by the side of the valve. Nothing obviously wrong with the O rings upon inspection.
I’ll put it back together tomorrow and see if the problem persists.
thank you for this video, it gave me an eye opening how a pump works as well.
Thank you very much for the video I liked and subscribed I found a decent pump on side of the road and now I know how to fix it that makes two to the collection LOL
Great video.
My PFP-8 (which is very similar) had stopped working for Schrader valves. The rubber ball had gotten stuck. I was able to dislodge it with some light banging. Thanks for the vid!
Keep it Up Luv your videos
Thank you! It helped a lot
Thank you for your video really helpful
My Ace Hardware has a few boxes of o-rings, $0.89 each, I have Serfas pump and Lezyne pump not a Park, but the 1-1/8" (OD) x 7/8" (ID) x 1/8" (thick) o-ring is what I needed and seems to be pretty standard on bike floor pumps, take the old o-ring into the hardware store for comparison to be sure, just eyeball it.
Do you recommend this park tool pp3 model or the new 8 model?
I had problems with my pump pfp-6 on the base of it where the blue metal go inside the black plastic base. How to fix this part of the pump?
Very good
i found a black burn pump. low preasure wont pump tires... and i open it up dont know if its gasket or hte hose at end of the head or base which i dont know if black burn model screws off. any tips.. and it has guage also
Wondering what you’d suggest to replace the little ball at the bottom of the pump?
hi. it looks like the lubricant you used is 'napa syl-grease', is that right? i've used a variety of lubricants while refurbishing my topeak floor pump but they have all dried up and started to 'drag' on the up-stroke. topeak does not have an easy-to-use support link where i wanted to find out what the original pumps used for a lubricant, which held up for nearly four years. meantime, i'll stop by napa tomorrow to see if they have the 'syl-grease'. thanks.
Thanks, I solved that
The air tube thing popped off my pump...I don't know if it's broken, but I was curious on how to fix it if it is.
I just got my first bike with presta valve stems and I need a dual head solution for an air compressor. Since your grease gun comments were so valuable what would you recommend for quality and reliability? (and so I do not have to have those presta adapters on hand ) EXCELLENT set of videos. You've helped me through LOTS of bike work and instead of one working bike I am up to 6, all mission specific. Looking at getting studded ice tires for my winter bike. Thanks RJ!
+BikingMNViking I like my Park Tool pump, but occasionally it doesn't seal well. I took apart the head and cleaned it and now it works better. I have a Serfas which works well, but the gauges it small and hard to read. I recommend going to Amazon and reading reviews.
Thanks for making this video for other. My lifeline floor pump is now pushing air out as soon as I reach 50 psi, it use to go up to 120 psi. Its 4 years old. Does that mean I need a new pump?
probably just needs serviced, if the o-ring is not sealing the air will leak back out around it.
I have an old Bontrager SuperCharger floor pump from like 2009. It has been AMAZING. All original parts and use it ALL the time. For everything. Just now it has decided to fail me.
It fails when pushing down. It doesn't build pressure. Like if you pull the plunger up (handle) and just let it go, it drops right down. No pressure is building inside the pump. Otherwise nothing wrong with it. Is this a plunger gasket issue??
Mine jumps off the tire valve. What do you think is wrong there?
thanks
I have dual valve Avenir pump and use Schrader valve. When I lock to pump air, the air comes out of tube and push pump handle up. So I can't pump air into the bike tube. Please help. Appreciate your video. Thanks.
Your description is not clear. And this video is for a Park Tool pump. Not Avenir.
@@RJTheBikeGuy Appreciate your response. The problem was little ball that works as a valve. However, you are the reason that I figured out after watching your video. Thanks.
@@drssdhillon2692 czcams.com/video/jlEj0sHEuGA/video.html
Where can I buy the small little ball from your video at 7:37?
So can this pump heads be installed/attached to different pumps made for inflating balls? thanks.
I don't know. Probably depends on the hose.
That would be funny if park sold a tool to fix their own pump 😂
hi man could you do one on PFP-8? pls
the PFP-8 is almost identical.
RJ, you skipped the disassembly/reassembly of the big seal between the metal tube and the base. That is the biggest problem with these pumps IMHO.
My pump does not show the psi when I pump a "car valve" but works fine when i pump a presta valve ..any ideas?
RJ, question for you!
I have a PFP-2 (I've had it for 20yrs, worked like a dream until... 🤦). The guage hasn't gone back to zero for over 10yrs now, but it still worked accurately for everything over 20psi. Last year I discovered that I could purchase a new guage for it - so I did. The plastic piece of crap came, and I installed. First time I went to use the new guage, once the pressure got to about 85psi, it would push the new guage up, off of its seat, and start to leak. So, naturally, I decided to go back to the old guage. Well, now the old guage does it, too. And I was wondering if you could tell me what the hell is going on, and if there's anyway to get it back to not leaking.
Also, what does the 5mm Allen screw do (because I've messed with that as well)?
Hope to hear from you. Thanks!
my hose broke, cannot seem to find hose only anywhere, any ideas? Thx
Great video, any thoughts on where one could get cheap o-rings in these sizes?
Sean Crosby Maybe an auto parts store? Harbor Freight sells boxes of misc sized o rings in both metric and SAE.
RJ The Bike Guy
Thanks! Yea, Harbor Freight. Good call, I forgot about them.
My Ace Hardware has a few boxes of o-rings, $0.89 each, I have Serfas pump not a Park, the 1-1/8" (OD) x 7/8" (ID) x 1/8" (thick) o-ring is what I needed and seems to be pretty standard on bike floor pumps.
What about when the base is leaking? It's like the only part you didn't cover at all.
Any idea what the o-ring size on the L-shape part is at 4:19?
Nope.
You mention lubricating the o-ring with a silicone-based lube. I've seen other recommendations for dry lubricant. In lieu of those, should white lithium grease or other common lubricants work just fine?
linguisticness Silicone is what is recommended by the manufacturer. It is safe with the rubber o ring. Other lubricants may damage the pump.
RJ The Bike Guy Thank you for the fast reply! The pump I was servicing last night (the o-ring had just slipped off, but was also very dry) was a Topeak Road Morph G Master Blast. I figured an o-ring was an o-ring and white lithium has never done me wrong, but I've never applied it to rubber and should have checked with Topeak first perhaps.
Mine is pushing back whrn pumping. I bought a new pumphead and it still pushed back. What shall i do?? Thanx for the advice
One of the ball valves inside probably.
@@RJTheBikeGuy just bought brand new heads for both pumps. Problem solved
RJ, my pump seems to be blocked or clogged. I get tons of resistance when trying to press down on the pump. Any thoughts? I plan to disassemble it tonight.
jcs311 Might be an issue with the valve head assembly. Do you get the resistance when not attached to a valve stem?
Yes, there is just as much resistance on the pump when it's unattached from a valve stem. I will follow your directions tonight and take apart the head. let you know what i see.
The blockage is somewhere in the plunger. I've disassembled it completely and even when detached from everything the plunger has 100% resistance when trying to depress it into the cylinder. When I remove the o-ring there is no resistance. BTW, it's a store bought Bell pump, nothing special
There is probably a one way valve to let the air go into the tire, but stop it from coming out. It is probably stuck.
Does anyone know where i can find balls like the one at 7:37? My air pump has a hole on the rear low side of the main cylinder and i started to believe that there was a ball in there. Now the air is leaking from that spot!
If i put the valve in the pump it leaks but if i put my thumb on the pump it doesnt. Any advice?
Overhaul the pump head or replace it.
I have a PFP-8 floor pump, my problem is the air is coming back and it pushing the plunger up. I hope you can read my comment and help me with this problem. Thanks.
Take it apart and clean everything.
@@RJTheBikeGuy thanks for the response..i already fixed it..the problem was the one way check valve, i just cleaned it.
my car type (foot operated) twin piston/cylinder pump has let me down while i was pumping up my bike tyre,i'm guessing that the o rings on the 2 pistons are worn out as sometimes the painted metal cylinder bodies get warm/hot during inflation,btw what was that grease u used on the pistons,was it silicon grease???,brilliant video rj thx :)
neil crompton Yes, I think it is silicone based.
ok thx
Very good video. One of the best I could find on subject
.
Hi ,great video- i'm not sure what the issue is with my pump- none of parts look 'worn out' any help pls
Well that is vague...
shyflirt1
hi, when i'm pumping up the typre i'm not getting pressure into the tyre. checked the plunger gasket and its looks fine.
what are the type signs of 'worn show i be looking for?
You gotta figure out WHERE the issue is. It could be the pump is fine and the tube has a hole (try a different tire). If you have the dual head on the pump, is air going out the other side. Is it leaking from a hose. Does the gauge move when you press down the handle. Did you lube gasket like in the video?
shyflirt1 Hi SF, I've located the leak, when I inflate the tyre, ive tired various tyres and when it gets to 60 PSI the pump basically wont inflate. the leak is coming from the connector 7.42 into your video- I've checked the O ring but there is no wear or damage. any ideas?
Paul Hughes You can try pulling the o-rings off and flip them so the opposite side of the ring is facing in to the mating service. Don't damage them as you pull them off. You can also get a replacement for the whole hose part. But be totally sure that is where is it leaking.
Every time i push down on the pump it comes straight back up and the pressure in the tire comes out. How do i fix it?
Check the little ball at 7:40 in the video.
thanks
I have the same problem. Pump is similar, but not exactly the same, and has a different brand name (Sunlite). There is no little ball in the location indicated in the video, nor is there room for one there. Do you have ideas where this "check valve" might be located?
The little cap of my pump was streaked by the force somehow. Anyone knows how to repair it?
That looked a bit too much silicon grease to me on the main o ring in the cylinder.
what the name of parts at 2.19

I'm gonna go ahead and go ahead
Why are you so jealous I am watching the bike guy he will tach me the repair step by step back off please from our society!
Hi
My Park Tools floor pump is fine except that it wont measure the amount of psi being pumped...any ideas?
Not sure. Does the gauge move at all?
It stays at the bottom when pumping air
If the pump works otherwise, it sounds like the gauge has gone bad. You might be able to get a replacement gauge. If the pump isn't that old, you might try contacting Park Tool.
Will open it up to see if something got loose inside anyways lol. I dont mind with my mtb tires since I can tell the approx amount of psi pumped. My problem is road bike tires, I already blew a tube lol
jee thx😒
