Loose barrel hinge (1 Viewer)

I have a pair of Pentax DCF 8X42 binoculars that have a loose barrel hinge. Does anyone know how to tighten this hinge? I am nowhere close to a service/repair depot for these binoculars.

Thanks, Steve
 
Did you try taking off the Tripod Adapter cover from the front of the hinge and seeing if you could tighten it from there? You might need a pin wrench to do it although some are slotted.

A set of circlip pliers should do the trick. before trying to turn the ring check inside both the pin holes - sometimes there is a grub screw in one of them the lock the ring in position.

Gary just a quick one if you don't mind. My Zeiss FL 8x32 underneath the focus wheel when viewed from the underside have a washer type thing that moves from side to side? I have checked with another pair and they also have this. Presumably this is normal??

Cheers
 
Perfectly normal.

It is a flat plate with two curved cut out grooves in it for the focussing shafts to go through.

As you open and close the hinge the plate moves so that the grooves stay in line with the shafts.

Thanks for that Gary, and thanks for responding.
 
Fully aware of potentially ruining my reputation concerning mechanical expertise by suggesting such an unprofessional method, I all the same share my (repeated) experience in a primitive (and a bit risky) way of successful bridge hinge play removal: One person permanently keeps the hinge in motion until (complete!) hardening to prevent locking, while the other person fills the gaps with a little threadlocking liquid.
