How can I fix the jerky motion of the 804RC2? What kind of lubricant can I use on the head?

Hi Shirley
-When you look at the center column you should see a small plastic 'nub' about 1/2" from the bottom.
-When raising the column in preparation to move to the horizontal position this must be depressed or it will not 'pass through' the top casting.
-Once this has occurred the column can be raised enough that it will then freely drop into the horizontal position.

motor in mirror sound broke, the jerking is most likely broking teeth on the motor, you need to replace it.

Extend the center column, there are 3 screws underneath that when unscrewed will allow the head to be tightened or loosened. The head is screwed on about 4 or 5 revolutions. You will need a flat head screwdriver. Take the center column out if you need to to be able to get to the screws.

Yes, it would be really hard to put on and equally hard to get off. Make sure the safety lock is release and a flat blade screwdriver should pop off the plate once the primary lock is released.

You can find that at: http://www.bogentripodparts.com/parts/head804RC.htm They are usually in stock all the time. Easy to replace.

Try lubricating the guide rods with either silicone spray or white lithium grease?
