Agree, this is also why I bought the harbor freight hydraulic punch. I slso bought a hydraulic cyllinder kit and a c-frame with forcing screw designed for ball joint removal and combined the parts accordingly. I've used these many times in various ways, like installing harmonic cranksgaft dampers and power steering pump pulleys, many press-fit assemblies.

I like your add-on hydraulics idea! I recently used one of the loaner tools from Autozone (totally manual force screw) and it worked my ass off! Hydraulic would have been SOooo much easier, but I could not find one as a loaner tool. However I suggest to everyone that instead of making all those bushings and adapters like you did just borrow the loaner bearing press kit and use those bushings. If you need to then buy a cheap-o bearing press kit it sets you back about $70 (ebay, harbor freight, amazon, etc.) Which is not too bad. Add a hydraulic pump to make things easier. Nice idea that! In any case DIY is way cheaper than having a shop do the work. It would have set me back $400 for my Prius, instead it was $40 (for the Timken bearing only.)
Great idea. I have a big old 3/4 socket set I use for pressing bearings in my 20 ton press that would probably work great with your setup. Off to Harbor freight.
Been using the pull and draw method the last couple of bearings i have done and now confuses me why people would use anything else. Great explanation...
+GTs Garage The problem with using a forcing screw to pull/push the bearing out is that if you don't lubricate the forcing screw, or use a cheap set such as most DIYer will buy from Harbor Freight, the threads on the forcing screw or nut will strip out. Using the hydraulic head you do not use the thread portion of the rod to push/pull the bearing out.
Do you remember the dimensions of the bushings you turned? I have an 05’ Forester, got that press but don’t have a lathe....If I knew the size, thinking I could get a machine shop to turn them. Awesome project!! Thanks for sharing!!
As an engineer - i wonder if you could answer this question. If you used two of these in series on the same threaded rod, would you double the potential force? I.e 20 T?
I just bought the Harbor Freight Front Wheel drive bearing kit, and a 3/4-16 10 long steel threaded rod from Zoro. www.zoro.com/proto-separator-rod-34-16-thread-10-in-j4333r/i/G6163297/ Use the forcing screw nut from the Harbor Freight kit with the steel rod. I don't have access to a lathe, although I did take a machine shop class when I was in High School. I do use it with the HF hydraulic press liked you. This info is for people who want to use the hydraulic press like you, but don't have access to a lathe to make all the cups and pushers.
I wonder why there isn’t one on the market for this specifically. Maybe you can license your idea to someone. I came here cause I was looking for one online. I couldn’t find one anywhere.
This is awesome, where can I get the different size adapters? I supposed I'd have to buy a kit meant for pressing bearings, along with a "porta-power"/ hydraulic ram, you think? Thanks for sharing this idea.
I bought one of these hydraulic punches and tried this on my camry front wheel bearings. first time I tried it stripped the threads out of the hydraulic head with a loud pop. also ruined the $16.00 threaded rod. wish it would have worked. had to go have them pressed in. the shop I used ruined one of the bearings pressing it in wrong....lol...I should have went to the mechanic :)
I suspect you had a mild grade steel rod or you did not thread into the adaptor far enough.. The steel needs to be a decent grade, the stuff at Home Depot (and their like) is not hard enough for this sort of thing.
