Hello,
I have had a Vicmarc VL200 chuck for about 2 years and it has been completely trouble-free, until now. For some unknown reason, upon closing down on the chuck it binds about 1/2 down requiring substantial power to close it down further. After about 4-6 turns it releases and works fine. Open it up and the problem occurs in reverse. I have tried heavy doses of WD40 without success. I have also removed the cover and inspected the inside. Everything looks fine, no debris, chipped gears or anything that I can see. The gears appear to have adequate grease. I do not want to dismantle the chuck to avoid the possibility of losing a part, I am good at that. Does anyone out there ever have a problem such as mine and if so how did you correct it? Any suggestions will be appreciated.
Thanks in advance for your help.....Ralph
