Tricky freewheel removal

[KipMcSkipster]

Hello,

I'm trying to install a rear DD MXUS (from cell_man) onto my bike frame. I attached a 7 speed DNP and a disc, and there wasn't enough clearance between the rear dropouts (135mm). I purchased a 6 speed freewheel thinking I would then have enough clearance, but am unable to remove the freewheel now on there. I just purchased a removal tool from e-bikekit, but no matter how I try, it doesn't fit around the MXUS axle. Any suggestions for how to get the freewheel off? Do I need to file the interior of the removal tool to get it to fit over the axle? It looks like it's close.

Thanks for any suggestions, I'm really eager to get this all put together!

Yeah, dremel the removal tool out a bit until you have clearance.

a round file works also, like the type used to sharpen chainsaw teeth !

You can file your freewheel removal tool to enlarge the hole to fit the axle, or get a freewheel tools that fit for 14mm axle from one of following site:

Thanks for the suggestions. itselectric - the removal tool I'm using is one that should fit over a 14mm axle - it unfortunately doesn't fit over the axle I have, for whatever reason (but it's close).

You could just pop the cover off and then remove the FW. That's probably quicker than modding your removal tool.

I used a step bit and electric hand drill to drill out a standard freewheel tool to 5/8" in a matter of minutes.

The one from itselectric.ca works like a charm on this motor.

KipMcSkipster:

Where did you get your freehwheel removal tool? If you got it from normal bike shop, none of them fit, it will only fit for 12mm axle. That is why you have made modification. The one that I pointed out, it is custom make directly from the tool factory, specified made to fit BMC, MAC, eZee, and Crystalyte 5x motor.

Heat your tool in a blowtorch or furnace until cherry red. Remove from heat with tongs or similar and wedge over FW while still maleable. Allow to cool to ensure sufficient rigidity to remove FW. Re-heat tool to disengage it from FW.

I may have to resort to your suggestion John, thanks.

Just to be clear: the freewheel removal tool I'm using IS custom ie designed for 14mm. I purchased it from e-bikekit.com (this right here: http://www.e-bikekit.com/shop/index.php?p=product&id=85&parent=15). It does not fit over the axle. I guess I'm wondering whether there's something off with the tool, or the axle?

I modded a standard bike shop removal tool in about 2 minutes, using a dremel and a Tungsten Carbide Dremel bit. It literally took 2 minutes to widen the standard tool wide enough, so if your custom tool is only a whisker too tight, it will take you no time. If you have a dremel, get the Tungsten Carbide bit.

 

[KipMcSkipster]

Filing did it, the freewheel is off. I think a dremel will be my next investment; it would have saved an hour of my life. Once again, thanks for all the suggestions for a seemingly insignificant snag.

 

[Erogo]

Dang. I was hoping you'd try the furnace.

I have a removal tool that I tried drilling with a step-bit, and there's no way it's cutting through this hardened steel, would take hours and prob ruin the bit.

Maybe the typical FR-1 you guys are modding is a softer steel.

I drilled a Park FR-1 removal tool in about 5-10 minutes with a 35 year old 3/8" electric hand drill, and an step bit I borrowed from a neighbor. just put the tool in a vise and started drilling. Drilled one side then the other to the 5/8" step. A few days later I received the special one I ordered, so now I have 2 that work.
