Hermle 451 and 1151 Front-Plate-Post-Issue
Hermle 451 and 1151 Front-Plate-Post-Issue, is that on rare occasions, the 451/1151 high bridge units have a post on the front plate of the movement that you have to remove. This is evident when attempting to put the dial on the clock. The post may hit the components on the back of the dial causing the clock to act up in a variety of ways. The solution to this issue is to just remove this post. It may sound crude, but to remove it, simply bend it over with a pair of pliers. The installation is by friction fit which makes this simple to do. It will bend over and snap off with a little bit of force. The function of the clock has no bearing to this post. If you have questions on how to do this, please feel free to contact us via email and we will be happy to help explain it.

I finally solved the issue thank you.
I just installed a Hermle 1161-850. It operates fine when the front plate is removed. When I install the front plate it will strike forever.
I am wondering if the problem is the one discussed in Hermle 451 and 1151 Front-Plate post issue or is it something else.
Thank you for any help you can give.
It sure sounds like the moon dial is bumping up against the front rack and snail portion of the movement. This is the saw tooth looking thing that needs to flop up and down upon going into strike mode, the exists on the outside of the front plate of the movement.
Also put the clock in strike mode and let it strike out the hours completely, then put the dial on and the clock hands. Otherwise the hour hand tube can slide forward enough to whereas the rack gets stuck behind the snail instead of falling on top of it. Thus getting pinched by the minute hand pushing back on the hour hand tube upon putting the hand nut on.
