How to Remove Mavic Aksium Freehub Body

Post by Valbrona »

Do you stick a 5mm hex wrench into the DS end of the axle, and then fit a 17mm wrench onto the locknut and turn clockwise ... just like removing a Campag freehub body? Or do you turn the 17mm nut clockwise.

Thanks.
I should coco.

As usual the answer and a complete how to video tutorial is available on YouTube for free!
(process same for all modern Mavic hubs)

Answers preferred please from people who remotely know what they are talking about. The video shows higher end Mavic QRM+ and QRM SL hub technologies, whereas Aksium is lower end QRM hub and quite different.

There is no NDS cap to pull off and the axle is a threaded steel one, so no chance of sticking a 10mm axle through into the freehub body from the NDS. The Aksium axle is a budget arrangement.

This guy has done it, but 17mm nut seems that tight I am wondering if you screw clockwise to remove it: https://fernandoj.wordpress.com/2013/09 ... ampagnolo/

Hi

It's not a job that I've done yet, however the tech manual doesn't specify a thread direction so I'd guess RH threaded, but it is only my guess

The 2012 tech manual (when my hubs were made) specifies using p20 and 21 of the 2004 tech manual for detailed instructions, which refers to various models except the Aksium. I can only assume that the process is the same. 2004 manual available here...

HTH (or not)
Regards

this may also help;

I have had mavic hubs with a steel axle and they have always had a RH thread on them. If push comes to shove you can often remove the whole axle (freehub, bearings and all) and the hold the axle in the bench vice as well as use the 5mm hex key.

Moderators; can this thread be merged with the other (virtually identical) one?

cheers

Here's something to soothe your febrile mind:

.1 MAVIC FREE PLAY ADJUSTMENT

Hub play must always be gauged with the wheel fitted and tightened in the frame or fork. Tightening the quick release skewer significantly increases the lateral pressure
exerted on the bearings. Therefore:
• if there is play in a wheel not fitted into the frame or fork, it may disappear once the wheel has been fitted;
• if there is no play in a wheel not fitted into the frame or fork, it is possible that tightening the quick release skewer will over-stress the bearings, thus damaging
them.

Adjust the adjustment nut by fully tightening it and then untightening it by a 1/4 turn, so as to close the quick release lever (CLOSE position) with a suitably large force.

However, a too large tightening force may damage the bearings.

This tightening force is a subjective parameter that is directly dependent on the end user, and as such it is difficult to accurately determine the optimum bearing adjustment at the factory.

In order to avoid any problems for your customers, we factory set bearing play by simulating an extreme quick release tightening force.

There is therefore likely to be some play in the hub of a new wheel fitted to a bike with a lower quick release tightening force than that used in the factory.

Apply the following procedures to set the amount of play.

WARNING: Adjusting the play is a delicate operation which consists of identifying the balance point between play and no play.

Having no play does not necessarily mean that the hub is correctly adjusted as the bearings may be over-stressed.

Basically the same hub design as the Mavic equipe, full guide here:

This has the been best tool I've found for repairing any Mavic wheels (which imo are 'consumables' and not intended or practical for more than a few thousand miles, the rim thickness will determine most of this) :
