How to remove a stuck Kowa 883 eyepiece? (1 Viewer)

[wolfbirder]

Any tips?

I have purchased an 1.6 extender, but having come to untwist the eyepiece from the scope, it is stuck solid and just won't come off. I am reluctant to twist it as it feels like it would eventually snap through sheer force.

Maybe a hairdryer to add some heat and then twist.

Hi,

sorry to hear this - in general the bayonet mount should be fairly easy to unlock - twist it around 60 degrees counterclockwise and then pull.

The lowermost edge of the Kowa EPs with the EP type stenciled on it is unfortunately fairly narrow (3-4mm) - above that there is the part which you twist to zoom which I would indeed not want to apply a lot of force to - unlike the edge below, if you can grab it firmly.

As for why - is it possible that the EP was last mounted in hot and/or high conditions and now in cold weather and/or low altitude air pressure presses the EP in firmly?

PS: and yes as Dutchbirder noted, a hairdryer (not a workshop hot air-gun!!!) pointed to the body around the EP might help, as well as lowering air pressure... either by going up or waiting for a rainfront...

Joachim, who has made the mistake to set his dive watch to the destination TZ on a plane once... bad move as I could not unscrew the crown for the whole vacation - luckily it was an automatic watch...

Maybe a daft question, but have you held in the black release button on the body while twisting the eyepiece anti-clockwise?

Doh.................many many thanks all of you, but Richard you have nailed it.
I hadn't even realised there was a depress button on the side of the body, as it was obscured by the case.

Problem solved.

Thx again all.

And it's great to have BF with help!

At least you didn't put channel locks on it and twist it off which is what I probably would have done.
