*** Buy one, get one 30% off any mix of pullers and presses (applies to individual tools only, not kits) *** This bearing puller is a blend of our tap-out and our wind-out bottom b racket pullers. Like our tap-out pullers, this tool doesn't need a recess behind the inner race of the bearing, it grips the inside of the bearing Like our windout puller, this tool doesn't need a hammer, instead, tightening the nut draws the bearing into a cup in a controlled manner This tool is suitable for many bottom bracket designs where the lack of a recess behind the inner race of the bearing makes our usual wind-out puller unsuitable. In most cases this tool is intended to remove the bearing from a BB, rather than BB cups from the frame. However, the 'Shimano Pressfit' option can be used to withdraw the complete Shimano pressfit BB. A flat area is needed around the outside of the bearing for the tool's 'cup' to rest on. The cup will have an inside diameter of either 39mm or 44mm, depending on the size of tool ordered. If there isn't a suitable surface for the cup to rest on (sometimes a problem for outboard style BB) then our tap-out type puller would be a better option. V2 Expanding Pullers Our blind wind-out pullers now use our V2 expanding puller design. The V2 tool includes several important improvements: Grip has been greatly increased by including a ridge at the end of the tool to engauge with the chamfer on the inside diameter of the bearing The force required to tighten the tool has been reduced by refinding the tool profile All of our tools are designed and precision machined by ourselves, here in the UK, and shipped internationally. How to Use This tool is easy to use. The method is illustrated on a freehub below, but the principal is the same for a BB. Note that each tool is specific to one bearing size. It is designed to match the internal diameters and width of the bearing and can't be used on bearings of different size. First, the expanding collet is inserted into the bearing and the nut tightened, causing the collet to grip the inside of the bearing: Next, the 'cup' part of the tool is placed over the collet and a nut screwed onto the end of the threaded rod. By inserting a hex key the expanding collet can be prevented from turning while tightening the nut with a spanner. Tightening the nut draws the expanding collet into the cup: Presses We offer a comprehensive range of bearing presses, available in all of the same sizes and kits as our bearing pullers.
