Hw25 breech latch spring issue

[TonyL]

Mmmmm...never had the pleasure of having a look at one of these at close quarters, Al. I hope someone knows the answer and you can get this sorted.

Al. I just tried to look on the Chambers site to see if the parts diagram might shed some light on this, but can't access it on this ageing I-Pad!

However, I just put "Weihrauch HW25 barrel detent" into a Google search. Came across the diagram on the Knibbs site, clearly showing the ball and spring. So you assume not a "sealed for life" affair and you should be able to access?

Might be worth pursuing the search on the web a little. I'd have a look for you but running out of time....

Hope you sort.

Hi Al, I don't know if this helps at all. Especially post #12?

Yes, the reference to the steel dowel is just for the '30, but guessing what is said about the ball and staking applies the same?

I bought some Meteor parts with a ball catch mechanism. It is also weak. I have not tried this yet but is the spring visible by a slot in the breech block where if you have three hands you could use a screwdriver to compress the spring and put a
shim washer behind the ball for preload.
I don't know about your HW but my Meteor does not look rebuildable.

Thanks for this Tony, the rifle is on its way to its new owner who is aware of the issue .. might be fixable by putting in a wider latch pin for the ball to ride over, the ball spring doesn’t actually FEEL weak, it’s all very strange..

Gotcha. At least you've made him aware, just like I knew you would. The mark of a gent. Hope the new owner sorts and enjoys.

The 25 is back in my stable .. I’m going to try measuring the latch pin first with a caliper and see if it’s that because the actual spring pressure seems pretty decent. There may be some way of fixing it yet …

The 25 is back in my stable after an amicable deal-reverse manoeuvre.

There may be some way of fixing it yet … Tricky problems are the best and it’s such a funny little rifle, like a HW95 someone put in a very hot wash…

Back in your stable as in the sale fell through or has the new owner asked you to look into the issue prior to committing?
