Compatible for all TC88, 96, 103 and 110s that use the B148 or the B168 bearings. This set will remove and install the inner cam bearings on both newer and older model Twin Cams and Dyna Harleys. We also have new Torrington-Koyo B-148 and B-168 bearings available in our store ! This set includes our Improved collet design. The design sold by others has the whole back of the collet threaded with two slots cut into the threads for turning a wrench on. Its simple, its cheap, and its bad. Use that design once or twice, and you may damage the threads where the wrench makes contact, requiring you to now clean up those threads before you can even get the nut off the collet and use it again. Weve worked around this issue by moving the threads up on the collet to allow for a more controlled grip and protection of threads. Weve also completely redesigned the installer plate, zeroing in on the correct hole placement by taking apart an engine. This set comes with our "T" pin for easier insertion and removal from the collet! Instructions are available for this set! 100% Made in the United States.
