A length of studding in the front of the crank, short length of tube, big washer and nut will finish the job!ian,
Are you talking about warming the bearing ? . I did use the other techniques you suggest. thanks
I warm the case to expand that and the bearing, with the rear bearing it will drop on all the way no need to use any kind of drift, warm the case and the outer also slides in without force. The Fronts are complicated by the crankcase but heat helps and once you get them on the puller/pusher can be used to seat them. I believe many crankcase lips have been weakened by smashing them on cold with a big hammer and drift! Also multiple impacts transferred through the balls to the races will do nothing for the life of the bearing. Just my thoughts and the way I do things, others may have alternative views.
