Making do with the tools you have. Way to go!!!! Not many folks spend enough time on a trainer to wear out the bearings. You can lift off those bearing seals with a strong scribe and pack the bearings with grease and the seals will snap back in place if your lucky. I do that on the small idler bearings for my super charged Lightning
TheEZGZ Agreed... Most of these trainers get ridden for a couple weeks, then sit in the corner. This one has been abused consistently for about 5 years. The bearing seals were turned into ribbons by the time I got to them!!! I would have rather repacked for sure.
Good stuff Greg...I'll bet lots of people lost interest and dumped their trainers when their bearings gave out or just went out and bought a new one..A fair price difference I recon.
What you did was a lot of work. I did something a lot easier and my trainer is way quieter and spins a lot smoother. I took the one side off, cleaned and greased the bearing. It made a world of difference. Actually now that I think of it, I have a different trainer and you probably had to do all that with your model. I should make a video of what I did to fix mine. I have a Radmax and it only took me about 15 mins to fix it.
A 3 legged gear puller works well for removal of bearings. Be sure to use the right size socket to hit only the outer race when installing the new ones. a vise works as a press for that. --From electronics repair, fans, shaft encoders and the occasional motor. Any motor repair shop can do this for those not willing to get a frame upside the head(that poor camera!)
Great video. Just pressed out my bearings on a Kinetic. The worn bearings were inside the fluid module so I'm planning to replace the fluid and re-seal it. I read elsewhere that Mobile DTE turbine oil is used on these trainers but that is a highly specialized product and is not easy to obtain. Has anyone tried replacing the oil with synthetic motor oil? What grade, and how did it work? Thanks for any advice.
very cool C-clamp bearing press! Seemed like they had a tight press fit on it. Very nice editing, you trimmed at couple hours or more of work down to less than 2 minutes! It's not easy to do.
turbocobra I actually shot this with the intention of a very short outcome. Funny how that changes what you choose to record. The housing for the bearing is actually plastic and there is a lip where the bearing sits. It has to POP out, not just press. That's why you see the whole rig angled on extraction... If I had a mill, I'd remake the part out of alum.
+Greg's Garage I had the same deal, it split the plastic housing a little but I put loctite bearing and sleeve super locking goo on everything when I reassembled it and now it's better than ever
Mine is making some noise, your video is what I needed to get the courage to disassemble it. Can you add to the video description the specs of those bearings for future reference? Thanks
CountrySideClub I suspect it is common. I don't know too many folks who actually USE their trainer like I do. Most people buy them, ride them for a season, then never use it again.
Not a lot of people wear theirs out ... in fact not a lot of people use their equipment past their first month or two. Says something to have actually worn out the bearings. This was seriously a subliminal message to me ;)
Lol prolly coulda heated up the aluminum with a heat gun. Bmp. Right in the head. THAT WAS EASY!. LOL. Holy shnikies. Either you do good editing or your a really calm cool cat. Lol.
