Flat 6 Innovations

Here the bearing puller is being initially tightened. Care must be taken to expand the collet as far as it will go as to pre-load it against the i.d. and rear of the inner bearing race, as if it slips, the collet will be damaged and will not successfully extract the bearing. Note how well the feet of the puller engage with the machined grooves in the special tool. We have also modified the bearing puller to have a hex to allow use of a box wrench rather than the wimpy T handle supplied with the puller.

Now the bearing is under load, awaiting the bearing to be dislodged. This requires extreme force, more than any of us ever felt comfortable applying directly to the case, hence the importance of the serrated tool provided by LN Engineering!

Here the bearing has just been dislodged and is being pulled fairly easily now. What allows the bearing to come out easily now is that the internal wire lock has been deformed, forcing it to compress into the outer race's loc groove, releasing the bearing from the housing.

Here the bearing is about 1/2 way out of the IMS tube.

Now the bearing is 3/4 the way out of the tube and the puller is removing the bearing like butter.

Almost there!
