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.

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.

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 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.

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. 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.

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!

Excellent tips - and thanks so much for taking the time to ID the Park Tool part numbers

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 so much. You told me EXACTLY what I needed for my EXACT floor pump. You made my day, bro!

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!

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.

thank you for this video, it gave me an eye opening how a pump works as well.

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

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?

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??

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

Mine jumps off the tire valve. What do you think is wrong there?

Wondering what you’d suggest to replace the little ball at the bottom of the pump?

That would be funny if park sold a tool to fix their own pump 😂

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.

my hose broke, cannot seem to find hose only anywhere, any ideas? Thx

Where can I buy the small little ball from your video at 7:37?

Do you recommend this park tool pp3 model or the new 8 model?

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.

Thank you for your video really helpful

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!

What about when the base is leaking? It's like the only part you didn't cover at all.

Great video.

Thank you! It helped a lot

Very good

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!

Keep it Up Luv your videos

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?

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.

Mine is pushing back whrn pumping. I bought a new pumphead and it still pushed back. What shall i do?? Thanx for the advice

Great video, any thoughts on where one could get cheap o-rings in these sizes?

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.

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.

thanks

So can this pump heads be installed/attached to different pumps made for inflating balls? thanks.

Thanks, I solved that

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?

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!

hi man could you do one on PFP-8? pls

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?

If i put the valve in the pump it leaks but if i put my thumb on the pump it doesnt. Any advice?

Any idea what the o-ring size on the L-shape part is at 4:19?

The little cap of my pump was streaked by the force somehow. Anyone knows how to repair 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 :)

That looked a bit too much silicon grease to me on the main o ring in the cylinder.

Hi ,great video- i'm not sure what the issue is with my pump- none of parts look 'worn out' any help pls

Hi My Park Tools floor pump is fine except that it wont measure the amount of psi being pumped...any ideas?

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!

jee thx😒
