J Head Spindle Assembly Not Dropping Out

You probably have to remove the stop ring on the front of the head. Also, if there is a ring at the top of the spindle for pushing the collet out with the drawber, remove it. The bearing pack SHOULD come out then, but sometimes the quill gets dostorted and binds it. If you will be replacing the bearings, then you can safely apply some force to it. Otherwise, you'd want to be pretty gentle with it after the preload ir removed. Can you get it to move at all? If not, the outer races are probably glues into the quill by congealed oil residue. That should yield to gentle persuasion. If it drops out a couple of inches and then hangs, the upper bearings are hanging up on something in the bore. Mine is like that, some corrosion got to the ID of the quill, and I can't get my spindle out.

Hello All.

I have a BP J-Pulley head. from what I've read in the previous posts, The spindle assembly should drop out of the quill. I have remove the nose cap screw, collet and drawbar. How do I get the assembly to come out?

Thanks, Dave

Thanks Jon.

I ended up tapping on the splined shaft with piece of round aluminum. You can access it through the top where the drawbar goes. Other than the spanner nut on the nose of the quill, nothing else holds the spindle assembly in.

Came out pretty easily with a hard rubber hammer. Bearings are old but don't seem to be intact with a half thou of play.

There shouldn't be any axial or radial play in the pair of bearings at the nose end of the spindle. If there is play, and the nut that clamps them together is made up properly, they should be replaced. A new set is about $250.
