Judging Interest - New Eccentric Hub/Chain Tension Adjuster Tool

Discussion in 'Multistrada' started by AndyW, Apr 3, 2012.

  1. Ideally position the bike so one of the slots/holes in the sprocket is at 3 o'clock, slide the tool in-between the chain/sprocket and the slotted outer section of the hub - looking through the slot/hole in the sprocket you can align the central 'prong' of the tool with a slot in the hub, a little 'jiggle' of the tool and it slides into position up against the raised step behind the slotted part of the hub.
    That's possibly not a great description.......I'll post a sequence of photos when I get round to it.

    2 piece item.......that would be possible but I'm not going there as (a) more design work to do (b) more expensive (c) I don't think there'd be enough demand to warrant the change. I guess you're thinking about something that'd be easier to slip in your luggage for touring? Maybe think about cutting your MKI handle and get a local metal fabricator to make up a 'link tube' ? Of course the same could be done with the MKII, I just don't want to complicate things from my point of view.

    Thanks for the interest guys.......the CAD drawing is being done as a favour but my mate is up to his eyeballs at work at the moment, all will progress soon though.
     
  2. I'm in for one too please.
     
  3. Very good description Andy - thanks
     
  4. I'm Don, Andy's partner in crime with this project!!
    A very good description by Andy for locating the tool on the hub and this method is preferred when the bike is on the side stand...much better leverage.

    The second method that I prefer, is the tool located in the vertical position (centre lug in 12 o"clock hole) with the bike on the centre stand.
    You can sit in front of the tool and see the guide, now it is simply a matter of holding it with one hand and gently hitting it with a rubber mallet.
    Hitting it anticlockwise tightens the chain, and clockwise loosens the chain (about 1/2 mm with each hit) I readjusted my chain for practice yesterday, it took about 4 minutes, so easy. :)

  5. Sorry all, I forgot to mention I've left the rear stone guard off permanently, so did'nt need to remove it for the adjustment.

    So, from loosening the two hub bolts, adjusting the chain and tensioning the bolts up, no swearing, no skin off the hands from slippages...... 4 minutes!! :)
     
  6. As I only got my multi yesterday I've not adjusted the chain yet, but memories of my 916 come flooding back to me, so I'm in.
     
  7. Using a hub spanner

    Hi Don and welcome to the forum! :D .........don't be a stranger, chip in regularly ;-)

    Thanks for the extra view on how to use the tool, I should have started my post with this is how I do it......always good to have alternative views / second (or more) opinions on these things :biggrin:
    I can see how gentle/light taps to the tool handle once securely in place might be good for for making adjustments in small increments (good tip, thanks) but I would like to remind everyone that this should be done with care - this tool will be stainless steel (and hub adjuster 'C' spanners in general are steel or stainless steel) but the hub is some form of alloy or aluminium i.e. 'softer' so too much 'impact' (hitting tool handle too hard) could cause damage to the hub 'teeth'.

    I posted this previously but no harm in doing so again!....result of someone using the blunt tool/screwdiver and hammer method to rotate the hub!

    Also I'll have to try the vertical tool (12 o'clock method) which I've not tried.
    I've always used the 'c' spanner horizontally (3 o'clock) and so it was natural for me to do the same with our prototype 'C' Spanner "plus".
    I thought this positioning easier for applying more body weight or physical strength to push down or pull up on the tool handle respectively (possibly safer also....less likely to roll the bike off the stand although not relevant if you only use the mallet tapping method;-)
    I'd recommend getting the hub 'moving' by hand first and the mallet for fine tuning then.....the hubs can be a PITA to 'break free' sometimes.

    Sorry to go on a bit, just feel it's good to cover all bases as I'll be making and selling the tool..........I guess I could have just said:
    DISCLAIMER.....use at your own risk, do any harm to yourself or your bike as a result of using this tool, it's your responsibility.
     
  8. put me down for one please

    As an aside if when adjusting chain you slacken before tighten the hub tends to be easier to move.
     
  9. Great tip....thanks :D
     
  10. "Breaking free" is the key word with the hub and the tool Andy, and you won't break wind using this one. D

    Very important guys...if your hub is damaged like the one above...obviously the "C spanner plus" may be difficult to fit!

    It might pay to give yours a close inspection;-)
     
  11. I will be up for one of theses as well please Andy
     
  12. Delivery by hand for you Chris :D

    Thanks for the interest everyone.......clearly worthwhile getting a batch made so no need for anyone else to post interest for the time being.
    I should have the final CAD drawing early this week and will then get final quotes and order a min batch of 20 but up to whatever max they can do for best value from the width of stainless sheet.

    Everyone that's expressed an interest so far will have first dibs - I'll PM you with details as soon as I can.......I'll then offer the remaining tools to anyone else first come first served.
     

  13. It would be great to see you riding again Andy. You still on target for back in the seat for the end of the month?
     
  14. The target WAS beginning of this month! :-( ..........had a set back pain wise but improving again, hope to get a few runs in before end of the month, SV1000 owners SW Rideout on the 28th which I hate to miss! I'll give you a shout as soon as I'm riding :D
     
  15. I know how you feel Andy - I had owned my brand new Multi for 3 days at the beginning of March after not riding for nearly 2 years due to a back injury & op, then sod's law invoked itself and I went in for a knee op.
    It was only yesterday that I felt confident enough to get the bike out & can report back that the knee held up for a 70 mile circuit and is still good today!
    Now to finish running in as I'm doing a Lands End / John O'Groats run in May.
     
  16. Like you I was unable to ride for 2 years (Jun2006 - May2008), a bloody long recovery! - my latest surgery back in October is hopefully the end of the major stuff and I'll be on the bike again any time. Definition of frustration......having an MTS12 in the garage and not being able to ride it! lol Hope all's good with the back and knee.
    What's the Lands End / John O'Groats gig? ........not much time for you to build your fitness back up!
     
  17. It stems from one of those "this is a good idea" moments in the pub!

    We just decided that we'd do it, but without using motorways except for the M4 crossing into Wales.

    We've set aside a week as we reckon it'll take about 4 days for the actual run without going daft, plus another 2 or so getting from the middle to each end before and after.
     
  18. Drop me a note of your route/timings for passing this way (Weston Super Mare) nearer the time....if I can I'll join you for a few miles or at least provide you with a coffee/loo stop :)
