Speedmaster 105.012 Pushers - repairable?

BatDad · Jun 9, 2019

Hi folks

Looking for advice on how to fix
There’s a lot of movement on the press in pusher caps in my 105.012.

They both freely rotate and move in all directions : see pics below.

Is it possible to disassemble them? And from there figure out what a fix might look like - or are they intended to be wholly replaced (presumably with svc skinny tube press ins)

Thanks
C

Sorry for the very obvious question, but have you screwed the rods/stems in all the way?

BatDad · Jun 9, 2019

There doesn’t seem to be any thread slot on the inside of the stem. I had thought that was down to them being a pressure fit not screw type pusher tube.

I didn't realize that. I guess you could try holding the stem in soft jaw pliers just to check.

BatDad · Jun 9, 2019

Yeah your comment got me thinking I should take another look at the ends. When I checked through the loupe both had no slots - but perhaps they were snipped for some reason.

This is my first 012 so have no experience with the subtleties, so my statement is merely my own conjecture

I do plan to reopen the case and try your suggestion to verify if there is clockwise movement

I believe these should be slotted. I looked at my two 012's and found that 3 of the 4 pusher screws were slotted and 1 was not. I removed the non-slotted one with a hemostat and replaced it with a slotted spare.

Here's a pic of the slotted screws:

And here's the non-slotted one:

Anyway, OP should be able to tighten his with a hemostat or Bat-pliers. Carefully.

Ack- non slotted. Bat-pliers on standby. 😉

Reporting back - despite careful being my middle name I’m not making progress in fact I think I’m just tearing up the current stems - that’s not a problem IF I can eventually get them out.

Current sit rep - after lubrications and a wash the RHS pusher spring doesn’t seem strong enough to return the pusher to our position - but does seem strong enough to pull the stem back into the case. See the diff in stem length with and without the hemostat.

Possibly sticky o rings or loctite? Any suggestions?

Interesting thread. Is it not better to show with a video?

BatDad · Jun 14, 2019

Maybe - but won’t that involve YouTube accounts/hosting of content and/or video editing skills. I didn’t think we could upload vids?

Either way I might just get the pusher popped out and try and disassemble from there.

Stop!
The pusher stems do not screw out, the stem is not fixed to the pusher button either.

If you are experiencing play in the pusher cap that is due to wear, there is a rubber seal inside at the top of the pusher tube which perished over time, I believe one perished this will leave

michael e · Jun 15, 2019

Some photos from the pusher graveyard to maybe explain.

BatDad · Jun 15, 2019

Thank you!! @michael e

Is it fair to say as I had originally thought the pushers for this case are intended to be replaced wholly?

(I have a pusher tool on order from ofrei and was planning on leaving this alone until that arrives)

Out of curiosity what does hold the pusher cap on and where is the spring? Internal to the pusher?

michael e · Jun 15, 2019

The spring is inside the pusher barrel.
The little washer fits over the barrel, then is held in place by pressings it into the rim of the pusher.

michael e · Jun 15, 2019

This is the clear rubber seal.

BatDad · Jun 15, 2019

Thanks again. I think I understand. Friction keeps the barrel in, and friction keeps the cap on. A tight cap seal is the result of a tight bind of the cap to the pressing.

How does one remove a cap?

Edit - thinking about this - presumably if the pusher is completely removed the washer will drop down the barrel and free the cap.

drhex · Jun 15, 2019

Washer needs to be a friction fit inside the cap or snap into a groove in there - can‘t come free if you pull the assy as the cap would otherwise fall off when installed. Would be interesting if the rubber seal can be replaced somehow.

wsfarrell · Jun 15, 2019

I've never seen pushers like these on a Speedmaster. Really looking forward to seeing how they are fit to the case.

Inspired by the responses above I attempted some further searching on the forum on the weekend. '105.012 pushers' wasn't the right search criteria to get to appropriate content. 086ST0089 - that's the ticket.

(Pic from the above ebay listing - )It looks like I have original wide spec push in.

Adding here for future ref.

The picture above seems to have levered off the cap and damaged the pusher shoulder - I'd prefer not to attempt that...

My current thought is - how will the cap hold up if I try and push it off by exerting force on the pusher stem? T

Nice find. Following this with great interest.
