Park Tool HHP-3 Home Mechanic Bearing Cup Press Tool - Professional Bike Repair Kit for Bottom Bracket & Headset Installation - Perfect for DIY Bicycle Maintenance & Workshop Use

I have used this to press a headset into a bike frame. It worked great. I don't know how I would have done that without this, other than taking my frame to a bike shop and paying more than the tool cost to do so. I now have it for future bike maintenance as well. Great tool.I needed it for a BB30. Will work for anything. Don't see how you could ever run out of length.I usually have my bottom brackets out 2 to 3 times a year for cleaning and lubrication or even a swap. I have been working with a homemade bearing press setup (nuts and threaded rods with washers) or a budget bearing press for years. Those setups worked but always required very very careful and slow installation. It also took multiple attempts to get the bearings in without them being cockeyed. Even when I was careful I often ended up forcing the bearings in at an angle that I was not comfortable with. It was always a cursing affair.Last week I took out my BB30 bottom bracket bearings and was having so much trouble getting them back in with my homemade press that I broke down and finally bought this HHP-3. I didn't want to mar or stretch the cups on my nice frame so I kicked down the $75 and took advantage of the free one day shipping. Lost and Found was two days away so I wanted the bottom bracket in order. I can't believe I went so many years without this tool. I had struggled for 1.5 hours to install the BB30 bearings with my homemade setup. I couldn't get them to align in the cups to my satisfaction. They just kept going in too crooked. I was even using the correct Park installation bushings for BB30. Once the new HHP-3 arrived, I greased it, assembled it and pressed the bearings in perfectly straight on the first try. It took less than 5 minutes. It was sort of a face palm moment given how much I struggled with these types of installs over the years. This might be one of the best tool investments I've made and I have only used it once. :) If you are having trouble installing your bearings straight, get this tool and get the correct bushing for install. It will make your future maintenance a lot easier. I'm looking forward to using it again.Buenas herramientas para el mantenimiento de la bici. Recomendado al 100%I was having trouble with some old school bmx cups. After hours of banning my frame I decided to make a DIY tool still didn't work it bent the washers. Finally I decided to buy this park tool it worked like a charm. Sturdy well built top quality. It seem like a lot of money for one time use but since I have had it I used it about 4 times already. Highly Recommend.For installing mid bottom brackets in BMX bikes, I've had other tools (including diy) that performed just as well or better than this device. This device does it's job, but requires a bit of trial and error aligning the bearings properly on certain frames (S&M, Heresy, and Standard) in my experience. It is really well made, and quite sturdy, but I cannot understand why it's priced the way it is.While it was nice not having to fiddle with wrenches and nuts, the two flat washers are still prone to slide around on your head tube, causing the cups to inset crooked. Took some trial and error to get right. The long handles (while again more convenient than wrenching on a nut and washers) interfered with the sharply anlged down tube on my 29er frameset, meaning I had to press the bottom cup in using force from the top. Note that the "pro" versions of this tool all have handles angled down and away from the frameset-- a superior design that would have avoided the downtube issue.One other annoying detail is that the threads on the rod were very coarse at some spots, making assembly difficult. One handle almost got impossibly stuck halfway down the rod after having spun freely just a few turns prior. Even some grease didn't seem to make this better. Of course once the threads are gummed up by poor manufacturing tolerances, it's nearly impossible to get enough purchase on the greasy, threaded rod to back off. I wasted more than a few minutes trying to bang the handles free in a non-destructive manner (block of wood, etc).Worked out in the end, but honestly I'd have gladly spent the extra hundred bucks (or so) for the real deal next time around. This tool did not make me feel like any less of a "home mechanic" than when I was dealing with fender washers and threaded rod from the hardware store.This is going straight back - it doesn't work on vintage bikes well at all.No matter how I tried, I couldn't get it to press in line - and once the central studding had wandered off kilter, it was impossible to get it coaxial again. I'm very disappointed with Park Tools, who usually make high quality products. Their premium version, which costs substantially more, has a stepped alignment system, ensuring concentricity of everything throughout the installation. This simply doesn't exist on this product, so how on Earth it is supposed to stay straight is a mystery to me. I'm actually annoyed with myself for not spotting this flaw before purchasing.Highly NOT recommended. I even dropped the b****y handle on a newly restored Raleigh 531c frame, causing (luckily) a small, barely noticeable ding. Not happy. In fact, it doesn't even deserve one star.Title says it all really. I like Park Tools as a brand, but hot damn, £60+ for a simple tool that pushes two bearings into a frame?The tool is literally a screw shaft with two press couplers on each end with a handle. Come on, for £60+? It’s such a simple task, something half the price is just fine. It smells like profiteering.I used this to install some BB30 press fit bearings into a frame. Like others I tried the DIY approach using a long piece of thread and some washers, but I just couldn't get the bearings to go in straight. Then with each failed attempt I had to dismantle it all and punch out the misaligned bearing again! With the HHP-3 tool it literally worked first time! I'm very happy with my purchase, yes it's expensive but hopefully I'll get more use out of it in the future.One thing to note is that it didn't come with any drifts for installing the bearings. I already had some which came with a removal tool. I wonder if perhaps the 1 star review on here didn't realise you had to use drifts and was just using the washers?Packaging - Carboard; much better for the environment.Product quality - Usual Park Tools quality.My use case - I am currently building my first road bike, it has PF30 shell and I needed to install my Praxis PF30 bottom bracket. I had read some indifferent reviews on this tool, however my opinion is that it is the perfect tool for the job. The universal drifts allowed me to press the BB into the shall with no drama. Thanks Park Tool.Overall opinion -Good quality too helped press in BB30 bearings with ease. Note this adapter does not come with the press cups you need to buy the adaptor for your bearing type.
