Tearing Apart an HSD Spindle for Maintenance
Question
Forum Responses
From contributor D: We've been faced with the task before and have opted to drop the entire router and send down to HSD in FLA for a rebuild. Unless you're real good and balancing, running it in, and keeping everything clean it seems like a worthwhile investment to let them do it. From contributor W: I had to take mine apart this year to replace the cartridge. Not too bad of a job, the only problem I have, the db level seems to be higher with the new spindle. I liked the noise level of the old one but the bearings had started making a little noise. From contributor N: I recently (several months ago) replaced the bearings on my Rover 23. The first time an upper bearing failed within two days. I gave it a second go as the bearings were cheap enough and it only takes 1hr to do. I had already made a tool to hold the collet clamp in place to remove the release shaft. I had read on the bearing website that the bearings need to be broken in. I didn't do this the first time. I made a program that started the spindle speed at 5,000 rpm and increased it by 2,000 every 15 minutes until it reached 20,000. It didn't like going under 5,000 for more than a few minutes. I also used grease by Dow Corning made for high speed spindles. It’s worked great since then and has been screaming its head off all day with no troubles so far and is quieter than ever before. It was to be a $6,000 plus exercise to exchange it so I thought I'd give it a go myself. It is after all just a motor, not a space shuttle. If it fails again, I'd probably give it one more try before passing it on.
