    Grease Guarding Surly New Hub

    We like the Surly new hubs...they are simple, fairly well made, cost effective and with lots of layup options.

    Have built up a number of wheelsets for winter fatbikes using the Surly hubs (all w/ Large Marge rims). Out of the box and prior to use, we're upgrading the hub with 1) Phil Wood Spec'd bearings and 2) Morningstar Soup / Grease for winter conditions.On a recent rebuild we took it a step further by modifying the hubs and making them grease-able in situ.

    Quick, fyi, description: Break the hub down as usual. Prior to reinstall of the bearings we drill a small thru-hole in the body of the hub. The hole is 3mm tapped and located dead center on the hub body. We remove the inboard seal on each Phil cassette bearing prior to install. (important to clean all shavings and metal filings from the hub; esp the axle cavity) Hub is then reassembled. Trying a couple different ways of capping the hole!

    With a small greasegun you can now inject your favorite grease into the center of the hub body. Once the cavity is filled, force / pressure will move grease down through the hub, across the bearings and out the outboard seals...purging the bearing of any unwanteds while refreshing the grease.

    Works well on the Surly Hubs. Same concept is applied to Phil Bottom brackets and the platform pedals we use!

    Martin, sounds great

    You might even try picking up some of the grease zerks Turner sells on their website, or get some from Rick at RTR. They're used on their pivots for easy maintenance, and fit a standard grease injection gun just like the GG hubs. Epoxy them into the hole you drilled into the hubshell and you're set.

    Good stuff, Rando

    Rando,

    Good suggestion...I like the flat lying zerks but always felt they were 'crud collectors' and however hard I tried, couldn't get the port completely clean prior to lubing.

    Decided to go with a simpler solution...went to NAPA and found some small nylon bolts, oversized them a little for the threaded 3mm hole in the hub body, torqued them in.

    I think it does exactly what I want, which in to provide a completely waterproof airtight seal...the treads mash in the threaded opening and the head of the bolt seats nicely around the curve of the hub body. Itz a onetime use thingy so put a couple extra bolts in my tool bag for field re-greasing...lookin good! I like it...
