    I seem to recall it is a Timken 203FF (they can cross the number over to their's), but that may not be correct. Many times when just replacing the bearing the pulley will be ruined when replacing the bearing only. Your mileage may vary.

    Are you preplanning so you don’t have any down time? The PN should be on the bearing when you take the pulley off. PM Zack, I think he has those numbers memorized.
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    Buy a couple. Practically everything that spins on many cars, hell I think even the swing arm on my bike use the same bearing! I try to always keep them in stock.

    I did have an extra from my Trilogy install but I just did some massive rearranging and tool box swapping in the garage so can't lay my hands on it.


    When pulling pulleys while doing cam swap/timing chain guides I found one that is a little sticky so going to change it out.


    Thanks to all!
