I'm experiencing some lateral play in the freehub body and am assuming this may be due to an improper (or lack thereof) spacer, but perhaps it's something else all together? Unfortunately, I can't figure out how to actually remove the end caps. From what I've seen online, it just seems like the non-glued endcap is just press fit on, please correct me if I'm wrong though. Do I need some special tool to remove this? Any help would be much appreciated, thanks!
Edit: 2015: darn near won the best South Island series (got second in age
-group)..woo hoo Racy Theremery is back!!
The play is certainly due to a lack of washer between this right side cap and the 6803 freewheel bearing. It could also be due to a bearing having play. It would have to be replaced.
Check out our hubs manual so you can see the exploded view:
Before I go and try this out, is there a concern of crushing the endcap in the vice? I'm assuming the endcap is aluminum so crushing/warping it seems highly probably.
That should settle it down and cancel any play you had on the hub.
You can remove the cap using the pliers with the cloth around the end cup and pulling it hard up. That should do the job, at least it worked in my case.
Is this a common issue with the hubs, or is it something that existed with older hubs that has now been remedied?
Always looking for more info on my gear, so any info on this would be great.
Also, this talk of adding shims; where are these found, and are they a Tune specific item, or something more general?
This will pop the end cap off.
I have three shims inside mine and these act as the bearing pre load.
if there is movement add a shim and try again until it stops but be careful not to go to many as it will bind.
I noticed my Mag 170 developed some lateral free play in the freehub after about 3 months use. This wasn't a big drama and i don't think it detracts from the high quality of the hub at all. i see it more as a bedding in process so to speak.
On inspection the free hub had 0.6mm of free play when mounted in the frame with the QR skewer tightened as normal. The drive side end cap came off relatively easily by hand. Ive since bought a Shimano 11 speed free hub which came with the Shimano end cap which seems a much tighter fit. to remove the Shimano end cap after the first install i just inserted an old QR skewer from the non drive side so that it contacted the inner surface of the drive side end cap and knocked it off with a gentle tap from a hammer. personally id be hesitant to tighten a vice on the end cap t remove it for fear of distorting it or the aluminium axle. I haven't tried this though and maybe far less clamping force is needed than I imagine.
When i initially discovered the issue i contacted Starbike who supplied the hub. They contacted Tune who sent me a small bag of 8 0.2mm spacers/shims (via Starbike) and said just to add shims until there is no free play remaining in the free hub when the hub is mounted in the frame with the QR tightened. simple fix. I believe Tune offer 0.1, 0.15 and 0.2mm shims.
I did ride the hub while waiting for the spacers to arrive 4 or 5 times however it was winter in norway so the few times i could ride on the road they were short interval sessions of maybe 20km each time. I thought at the time that the free play was causing poor shifting of the rear dérailleur but in hindsight im not so sure. i think that old dérailleur is a bit suspect....have since installed a new group set so cant confirm this.
