Jerry, I'm sorry to say I don't have any information on servicing the Sinar Pan-Tilt head. You might try contacting John Wimberley by email (firstname.lastname@example.org) to see if he knows how to service the Pan-Tilt head. John was very helpful to me when I serviced my Sinar Norma recently; he also reviewed the service guide I wrote. I know he uses a Sinar Pan-Tilt head, and services his own equipment where possible, so he may be able to offer some guidance.
