      Marine Grease is far more better than White Lithium Grease, I've used Marine Grease for 8 years straight on my bushings on my Devinci Remix 2, even though I ordered a new bushing kit back in summer 2016 when I was asked what I used to grease the bushings I simply said "Marine Grease". My bushings really didn't need to be replaced cause there wasn't any signs of wear or erosion but I had them replaced even though one bushing (drive side) was crushed. Marine Grease is "THE BEST" when it comes to lose bearings in axles and headsets, I'll be enjoying my trail bike for many years down the road...

    By taking the mystery out of how many of these repairs should be done, you have motivated me to work outside my comfort zone. Things I would never have considered possible for me in the past, I'm not afraid to tackle anymore. Keep doing what you're doing.
    In addition to that you have saved me a lot of money.
    And . . . . . , I've made friends I wouldn't have made before. I was pulling into a picnic grove one day to take a lunch break. There was a young guy sitting at a picnic table intently watching something on his phone. I was a good 30-40 feet away from him but I could hear your distinctive voice so I said, "Hey, you're watching RJ the Bike Guy, aren't you?" Next thing you know we're comparing bikes, parts, experiences, your video, hints and notes, etc. It was the highlight of my day!

    Nice job, RJ!n. I saw that someone suggested heating up the freehub to allow Phil's oil to more easily penetrate the freehub mechanism. I do something similar. Heat up a pan of water till it boils. Turn off the heat and take the pan off the burner. Put the bottle of Phil's Oil in the heated water for several minutes. At this point, Phil's oil will flow much better into the freehub mechanism. I do the same thing when lubricating freeWHEELS after they've been thoroughly cleaned by soaking in a solvent. (No need to take the freewheel apart.)

    Great video. I am new to the channel but have been working on bikes for over 50 years. One tip to get the bearings in easier is to partially insert the axle and drop the balls in by hand . Once they're in go to the opposite side and check all is well spinning the axle using the cone end against the balls. Also have found using two cone spanners on opposite sides of the hub with the locknut finger right is easier to adjust the axle for play . You want it just a little tight, then as you tighten the non drive cone against the locknut the axle frees up a touch with no play or stiffness.

    OMG I literally had this problem the other week after having my bike serviced, I noticed it would chain slap and I assumed my chain might have been longer than needed because I had it replaced and the mechanic said he had to reduce the number of links but I forgot to count the number I had and here I am finding your video with what is actually happening with it!

  • @demirmahir
    @demirmahir Год назад

    Thanks RJ! You're a saviour. I knew right from the start when I read the title that you have the solution, made myself a coffee and enjoyed your work.
    I was regreasing my hubs and the extra grease seemed to gunk up the freewheel and the chain was going slack when backpedaling.
    I managed to clean the freehub with disc brake cleaner which should be some kind of mineral spirit based solution. It dries extremely fast and since it's a spray it can penetrate the freehub nicely. My bike runs smooth again! Thanks again!

  • @eccehomer8182

    Handy tip: A lot of free hubs require an 11mm allen key. However, you can use a 3/8" square drive extension bar from a socket set if you don't have that... it fits perfectly.

    or...if you're in a time crunch, just get some carb cleaner and blast everything you see. That's what I did, and chain snapped back tight when I stopped pedaling. I'm sure the carb cleaner was a temp fix, and tearing apart the hub/bearings is the ultimate fix. Thanks for the video...!!!

    Nice job RJ ,and Happy Holidays to you.
    Having wrenched for several years to support my racing habit (many moons ago) I say, 'Right on". Agree with everything you showed and you showed it well.
    Just to add a couple bonus points I've picked up:
    I also use a marine "paste", with MoS2 but I found originally it seemed to thicken the colder it got so now I add 2-3 drops of 3-in1 to each race before I close it up. Same with the cranks. Both Dura-Ace.
    Also, about adjusting cones: I'll allow a slight bit of play, and have found that tightening the skewers compresses the cones together a miniscule amount, usually just enough to take out the play. It's about as free-spinning as you could want while keeping constant contact with the bearings. A racing tip.
    Thanks for sharing.

      @peterwillson1355 Год назад +1

      @RollinRat in my experience, cartridge bbs are useless. Stiff to turn when new, a brief period of Good, then play develops...I use "vintage" bb spindles with cups and loose balls. I only asked because so many people rage about great quality wheel hubs but then accept in a bb what they would NEVER accept in a wheel hub.

  • @DualDesertEagle
    @DualDesertEagle Год назад

    Funny story: My Allmountain Enduro's old rear wheel had a bad freehub body on it and it did have a tendency to get stuck while riding, often leading to me stomping into a whole lot of nothing while trying to pedal for a short boost. There were a few times where this almost caused me to crash but I was lucky and got away with it.
    To fix that I opened up the freehub body and cleaned it thoroughly before putting it back together, but the problem persisted. I ended up taking out the thinnest of 3 washers in there (and I may or may not have watched 1 of ur other videos to learn how to dis- and reassemble a freehub body) and while that gave the freehub body some very slight play on the hub it finally freed it up enough to not get stuck anymore. It was only meant to be a temporary solution tho since I was planning to replace the wheels anyway.
    Now that I have indeed replaced the wheels with a NOAhubs custom wheelset and also replaced the old 3x9 with a 1x9 drivetrain with a much bigger cassette it turns out I'd better make sure to keep the new derailleur's clutch engaged since the massive new cassette takes a moment to come to a stop as I stop pedaling abruptly and puts a small but noticeable amount of slack on the upper bit of chain, then gets turned backwards slightly from the tension in the lower bit of chain and yanks the cranks back slightly as the upper bit of chain tensions again and stops the cassette's backward spin. With the clutch engaged it's noticable but not problematic, with the clutch disengaged it starts to get somewhat worrying. Kinda fun to play with while freewheeling tho.
    I guess I should look for a lighter cassette when the time comes to replace the current one.

    You make the cone adjustment look easy. I always struggled with it on these old school hubs. One note, when you were blowing compressed air, the wheel was right under and you could have gotten some WD-40 on the braking surface.

    I’m an old pro at freehub maintenance. Get a rubber stopper that plugs the hole in the removed freehub body. Then you can really blast out all the old gummy stuff with compressed air. With the stopper in place, fill the bearing cavity with 75w-90 automotive gear oil (I use Mobil 1 75w-90). Set fh body upright on a towel. When oil soaks through, pour out the excess, wad up a paper towel inside, turn fh body upside down to allow excess oil to drain out. Wipe it clean, reinstall on the hub, and finish.
    I find Phil oil too sticky, especially in cool/cold climates. Lighter gear oil is superior for this. And it’s cheap!

  • @JohnRglmtz
    @JohnRglmtz 7 месяцев назад +1

    I have this exact problem. It manifests itself when coasting in the small cog in which case the chain gets pushed forward and starts flopping around. I thought it was just weak springs on the RD but after replacing the RD a couple of times, I can see that it's the hub sticking. I like how you boldy go and completely disassemble the freehub, but in my experience, once I start messing with the bearings, the result is never as good as it would be with a brand new hub, and so when this happens, I just replace the hub. By the time things start to go wonky like this, the inside of the hub is probably pitted badly so replacing the bearings might work for a while but eventually it will start to wobble again.

      I saw the older videos first, made my 21mm socket tool & greased my Exage freewheel mechanism as shown there. Now I notice it stops right away indeed.
      So, should I degrease it and apply some oil instead? I'm at a loss.

I loosened the screw until it didn't rub against it and that stopped the chain from going slack.

    I saw something that had me scratching my head on Wheelers at Large. They undid the through axle and removed an end cap, and off came the cassette and freehub together. Apparently Hope and DT Swiss cassettes are retained by the dropouts! I carry the Stein tool and extra spokes on longer tours, but it wouldn't work on a carbon frame.
