My primary drive clutch basket, with taper hub, is going onto the main shaft too far and/or the taper doesn seat properly. What is causing this?
Verify that you have the correct hub, because we build three different hubs for different applications for 4spd & 5spd tapers. The angle of the taper cannot be cut incorrectly, as far as seating to the main shaft. However, the perpendicularity of the taper could be out of tolerance, but you would see a severe wobble in the basket when it spins. It’s not uncommon for an individual or shop to over tighten the taper hub and push it too far onto the main shaft. If this occurs, your basket may rub and you will not be able to remove the hub from the hub bearing. If over tightened, the taper in the hub “mushrooms” out and will not allow the hub to be removed without modifying the exposed part of the hub, at the opening of the taper. In some cases, the taper has been pushed on to the main shaft so far, that it has cracked the inner bearing race (if you think this has happened, you can feel a “notching” while holding the hub and spinning the basket). The components go together with ½ of 1/1000
