| p.1 #4 · Bogen 3275 / Manfrotto 410 geared head - question. |
My Manfrotto 410 gear head has no slop at all when I try to wiggle it, and the way they work, there should be no wiggle unless you force it pretty hard. No ball head of any kind should have slop or wiggle when locked. My head happens to be at least 8 years old, and also came from eBay.
Do the outer spring loaded "locking" parts of the knobs move freely to release the axis, and then spring back smoothly and firmly to lock the gear action? Their spring action should feel pretty firm when you turn them to release the action, and they should move back and lock as you release the pressure on the outer locks. If you can force them further toward the locking direction, which is counter clockwise, and that makes the slop go away, then you know your problem relates to them.
One thing that could happen to a used 410 might be that the lubrication is dried up from heat or age, and the spring loaded locking knobs will not spring back fully to cause the locking action. If that is the case, you might get it to work better by repeatadly moving the locking parts back and forth. I have no experience with opening up a 410 head to lubricate it. It looks like the rubber cover of the main knobs needs to come off first, but I am not willing to try anything to my head. And if you explore in there to take things apart, be careful of the spring action, which may fly off and cause injury, and also may require special tooling to be put back together.
You may have discovered why it was sold on eBay. I hope you have recourse, but many sales are listed as "no returns allowed".
