W German PUW 661S - Different Looking Shock Setting

WestCoastTime · Jan 1, 2023

First time working on a PUW movement, & the shock setting is not a type that I recognise.

I'm thinking that a screwdriver blade whittled down to a "pickle fork" could gain purchase on the middle part to then push the shock spring to the left in order to release it. But if anyone has alternate recommendations I'd be happy for the advice...

Squeeze towards the middle with tweezers?

Looks to be a variation of an Incabloc spring.
I would use a probe to push one side inward (using the rectangular cutout) and fine tweezers to release/lift the leg of the spring from the housing.
Repeat for the other side.

I'll give this a try. From what I can see of it, does not look to be hinged like a conventional Incabloc, but maybe the right side of the shock spring wedges in underneath instead. Will find out!

@JimInOz had it right; treat it like an Incabloc.

Thanks!

Doesn't appear to be as well hinged as an Incabloc.
It looks a bit like a jumping frog, also as if it could be quite "sproingy".
Installing will need care.
Probably hold the frog's head in the housing with a fine probe and use tweezers to ease each leg inward and under the housing.
