Hi.
I need a new set of pushers for my 105.012-66 CB.
I can pretty easily locate a set of drive in pushers (086ST0089) but mine need to be screw fit... Anyone know the service parts number for these?

 

Anyone?

 

The CB didn't come with screw for pushers did it? Aren't they friction fit?

Has the case been modified to take screw fit pushers from a 145.012?

 

I am not sure if case for friction fit pushers can be modified to fit screw fit pushers, or the other way around? Which hole is smaller ?

 

Pretty sure screw in tap is smaller and can be modified to fit friction pushers. The opposite isn't possible.

 

Does the case have the CB facets?
Could it be a 145.012 case?

 

Its a CB case with facets and the slimmer profile too...

 

Speedmaster101 states on the 105.012 that "Some are screw in and some are drive in..."

 

So one would need to check the dimensions of the pushers (both screw and drive in) and the pusher "hole" in the case...? And then possibly be able to widen/drill the hole in the case to take the (bigger) drive in pushers? If so I would want a very skilled craftsman to do the job for sure...

 

Is that in relation to all 105.012's or just CB's? I don't recall seeing a CB with anything but friction fit pushers.

 

Hmmm.... He doesn't specify that.

I'm not saying I'm definitely correct, just that I don't recall seeing one. You'll need to do some searching as this must have come up before.

 

I hear you... [emoji106] I have been researching and will be even more so now [emoji4]

 

If this is true for the CB case you should be able to find the Omega replacement part number (not necessarily the part though) for the screw in pushers.

 

Screw in pushers for the 105012 are 086ST0007.

Cheers, Al

 

But will they fit the CB case, which I thought has only friction fit pushers?

 

Hi Al.
I know this is the parts reference listed by Omega to fit the 105.012 also. But the cap is 5x3.5mm which is the dimensions that is correct for 145.012 and later so, correct me if I'm wrong, this is not correct for the 105.012 which should be 5x3mm (or even <3mm)...

 

086ST0007 is screw in... And both screw in and drive in cases (105.012) are found to exist

 

I understand it may not be like the original pushers, but it's not "wrong"...there is no other replacement threaded pusher for this case...

 

I understand the issue for the HF cases have screw in pushers. CB have friction fit pushers.
BUT the question to me is, are there any original CB cases with screw in pushers?
