How do I know if my free hub needs replacing?
Check the freehub for wear to see if it needs replacing or just cleaning and relubing. To do this, firmly grab the splined body and give it a wiggle. If it moves more than a couple of millimetres side to side, replace it.
Can you service a Shimano freehub?
To service the freehub, begin by removing rear cogs. The common Shimano® freehub uses internal loose ball bearing, pawls and springs. The small ball bearings are available as replacement parts. However, if the bearings are worn out and require replacing, it is very likely the entire freehub is needing replacement.
What is the difference between a freewheel and a freehub?
The difference between a freewheel system and a freehub system is in the location of the coasting mechanism. On a freewheel system, the coasting mechanism is built into the gear cluster. The term “freewheel” refers to the whole gear cluster with the coasting mechanism inside.
Why does my chain drop when I pedal backwards?
If it has a derailleur your gears need adjusting. We properly adjusted shifting system will allow you to pedal backwards without the chain coming off. Something could be bent, like the derailleur hanger or the derailleur itself. If it’s a singlespeed, this means the chain is out of alignment with the two sprockets.
Can you tighten a freewheel?
To tighten a freewheel, all you have to do is get it finger tight and then re-install your wheel and go for a ride. The freewheel will tighten itself while you’re pedaling!
Can I swap freehub?
Across manufacturers, there is no real freehub swap compatibility (barring cases where two different OEMs use the same Joytech hub etc). Within manufacturers there can be some.
Can you over tighten a freehub?
You can definitely overtorque it, as you know now. Every casssette I have the 40nm is stamped right on it. balatonman wrote: I read a few articles on how tight the lock-ring should be, and it sounded like you can’t really overtighten it.
How tight should my axle be?
You want your rear axle very tight. 150 in/lb is about standard. If it is not tight it will allow the rear wheel to move around and it ties your rear triangle together. Basically the whole back of the bike will feel sloppy.
How tight should bike cones be?
For quick-release type hubs, snug the cone down until it contacts the ball bearings, and turn back counter-clockwise one quarter turn (90 degrees). This will purposely make the bearing adjustment too loose. Hold cone with cone wrench and tighten locknut fully.
