Freehub Replacement Info Needed
 

Sold a Burley Samba tandem 3 months ago. Yesterday the new owners, my sister & b-i-l rode by and asked if I knew what the grinding sound was when they were coasting. I told them no coasting but they weren't having that answer.

Shimano tandem hub FH-HF05. Was 7 speed, I changed the freehub to 8 speed about a year ago using one I picked up from my LBS. The freehub had failed so I replaced it with a new one I had on hand. FH-1056, new bearings, grease and back on the road.

Is there a better/stronger freehub I should use?
Is there a "correct" freehub?
I would like to find a reliable replacement since the bike seems to have a lifetime warranty.

Thanks

So did you replace the whole wheel with one using an FH-1056 hub, or did you just swap the freehub body with one from an FH-1056? Shimano hubs for "singles" are pretty strong, so I'm tempted to think it would do the job unless someone has a correction to that.

Having trouble finding info for the FH-HF05 specifically. Pictures would help if you have them. :)

Did you hear the noise? When a freehub coasts, it will always make a rapid whirring noise as you know. Perhaps your sister and b-i-l heard that, and not anything that indicates damage.

Sorry for my lack of clarity. Hubshell only.
I tried hard to find a diagram for the FH-HF05, did find one for FH-HF08. http://www.sjscycles.com/Drawings/Sh...8_Tech_Doc.pdf

Yes I heard the noise. I'm not much of a mechanic but it was loud and clear. Rocks in a hub cap came to mind.

Here is what I removed. Right hand dust cap separated from the body?

Looks like that freehub body (part 17) attaches like the majority of them. If that's all you swapped, you should be good to go with no further concerns. :thumb:
