Fixing a Leaky RF-45 Mill Head - Grizzly G0519

[henryarnold]

I removed the quill spring return first. Be careful while doing this because it can spin and injure you. Loosen the nut on the end but don't remove it until you release the tension. Back the housing off its notched pin and then with a firm grip slowly unwind the tension. The spring attaches to the downfeed spindle with a slot over a flat head screw. You'll have to jiggle it around to get it to release. The photo should help.

   

Here are the parts from the quill spring return plus the guide pin for the quill housing which must also be removed. The plate has 3 screws holding it to the head.

   

IMPORTANT: Lock your quill before going to the next step because it can fall out when you remove the down feed mechanism which is the only thing holding it in place.
