I'm looking at swapping out the S2's steering bearings as I've got a definite flat spot in the steering that I can feel. Any new tricks or tips on removing the old ones and installing new ones? How about any current replacement bearing/race part numbers? Sealed vs unsealed, any issues? Any updates to grease zirks (sp?) in the steering head and then the swingarm pivots? (insert additional 1,000 stream of thought questions here) I'm also thinking of getting one of these from ParkTool: http://www.parktool.com/products/detail.asp?cat=50 &item=HHP%2D2 Does anyone think it would work? I'm working part time at a bicycle shop and get a discount on personal use items and tools. I figure I'll get around to doing this between now and August, or soon after the first tank slapper. Any help, input, thoughts, alternatives, money would be appreciated. Thanks. |

The tool above is for pulling the new cups into place and will handle cups up to 1-1/2" in diameter. For removing the cups a typical process is to drop a two piece driver into the tube. Imagine a round, stepped, piece of metal that would fit in the tube and rest against the bottom of the bearing cup. That piece is made in two halves or cut in half across the diameter and once it is dropped into place, a stepped shaft is inserted into it from the other end and the race or cup is driven out. And "driven out" is not, by necessity, a damaging or malicious process. If the tube is warmed and a malleable faced, non-rebounding, hammer is used it is a widely used and perfectly acceptable technique. Another option would require bridging the cup from above, locking a pulling piece under it and using a screw to lift it from the bore. Another option from above is to use a sliding hammer on a rod threaded into a lifting piece. There are some very remarkable (and expensive) tools made for removing bearing and races. I think my first approach on steering head bearing races or cups would be to get or make a round metal disk (a washer?), thin the sides until it will slide through the bearing into the tube, then use a threaded rod, a couple of nuts, and a heavy sliding weight on the rod as a lifting hammer. There is another thread going here on bearings and bearing removal with some other options for tools to use and techniques. http://www.badweatherbikers.com/buell/messages/142 838/354735.html?1208806260 Jack |

Thanks, I hadn't seen that thread. |

Mike, I did mine with sealed bearings. SKF's if memory serves. I think I have a spare set in the garage, I'll check and get back to you later with the number (If I have a set...). BTW, they are the same as the swing arm bearings. Brad |

I am planning on upgrading my chassis bearings with ceramic after I try a trio in my spare PM wheel first. Joe |

Appreciate it Brad. I've chipped too many ceramic dishes to be comfortable with ceramic bearings. |

Mike, Sorry for the late post, I did check the "spare parts bin". I don't have any of the sealed version, just a stock Buell part. I remembered buying a spare set but the were the stockers for the swing arm. Same bearing but I decided to go with the sealed version and kept the stock set as an emergency spare. The bearing number should be in the KV somewhere, I did a quick search and didn't find the link... Mike, I found the link! http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=3842&post=163016#POST163016 Brad (Message edited by bluzm2 on April 26, 2008) (Message edited by bluzm2 on April 26, 2008) |
