changing belville washers

[Shizzlemah]

Hey guys,
Time to do a little preventative maintenance on the Fadal. I don't know when the belville washers in the drawbar were last changed (been 2+ years) so this seems like a good time.

And tips/tricks/difficulty? Never done this before and wondering what troubles I can run into. 1988 vintage machine (so that's a non-locking drawbar, correct?) no through spindle coolant, kinda boring I guess!

Thanks

dig through this forum, I posted about a year ago a pretty detailed step through of the procedure for a non locking drawbar and spring change.

Heres the short version.

Remove the sheet metal, get a gear puller from a local auto store and the Fadal specific tool (from Fadal) to compress the spring retainer on top. stick a bar into the spindle to support the drawbar. Compress the retainer enough to get the two little clips out from the groove on the drawbar. Undo the gear puller, remove the springs and any fragments along with the drawbar. Watch for the ball bearings falling out the bottom, that were retained by the drawbar. I stuck a box under the spindle to catch them. Grease all of the springs.

replace everything and reverse to re install.

The procedure is also outlined in the Fadal manual you can download off of their website.

When you replace the springs might as well replace everything else too, drawbar, retainer etc. Fadal sells a rebuild kit.
