My Seiko 7009 rebuild was going well, all of the train of wheels spins freely and the main spring and balance are undamaged. however once wound, ratchet wheel seems to not be receiving power. the barrel will rotate for a quarter turn or so and then seems to get caught.

 

all parts were cleaned and all pivots are undamaged. watch will run but only for the quarter turn of the barrel. 

Sound and resistance comes from circled area, I believe it may be rubbing against the click but am not sure

Hi. Do a recheck, remove everything and re fit the barrel and associated parts and check again it’s like Joe said bent , Brocken teeth, or even some hard grit in the teeth. They are usually quite straightforward.

Rubbing is due to unlevelness of the turning parts, if you see no damaged teeth/part, the sound must come from a broken part or mainspring slippage. 

Does it run if you rewind after each stop?

Hard to tell but from the angle in the photo the click looks misaligned. There is very little clearance for this type of seiko click…

…not that you didn’t use care. I’d second the idea of just doing a refit…the good news is there’s room to adjust the position. Bad news is there’s room to adjust the position…

Is the loose end of the click spring stuck under the train bridge?

Looks like it. I did the same thing when I first serviced one of these. As @rehajm shows above, you have to pull the end of the spring out before pushing down on the bridge.

Yeah, it looks like that’s what I did wrong when assembling. I never pushed the spring fully out of the way when installing the barrel.

Yes, it will run for a bit until it seems to catch again. I had inspected the barrel and didn’t see any signs of damaged or Bent teeth

OK, So I recleaned and reassembled the train of wheels, and assembled it with the spring in the correct position. While doing this, I realized that the clutch wheel was falling to the side and jamming the barrel,  I had taken the stem out to fix the end as it was bent. To fix the rubbing problem I just had to reinstall the stem. problem was so simple. 

thank you all for the advice and help with troubleshooting.

      Rolex 3135 rate variation with temperature

      By steve1811uk · Posted

      Looked into this some more and I believe that some of the increase in rate is attributable to the drop in amplitude after 12 hours off wrist, from 300 to 275 degrees horizontal and some is due to the lower temperature (38 to 18 degrees). I can see that approx 3 to 4 seconds a day is attributable to each. I can be happy with that.

      Link below shows the tool used to push the stud out. You can make the tool , just file a screwdriver to this shape.  https://www.esslinger.com/bergeon-16918-etachron-stud-remover-screwdriver/ There are vids on YouTube showing how the stud is to be  push out. Shouldn't get over creative, just go by this approach.  Good luck.

      Almost ready

      By Embezelled · Posted

      Hi all, I'm almost ready to make my first attempt at watch repair. My initial goals are very modest, just to get an inexpensive watch or two to work on, and take it at my own pace. I have what I think are the necessary tools on the way. A couple of things arrived already: a loupe, some tweezers, and a cheap demagnetizer. After looking at the options for oils and grease, I decided to start off with Citizen A-O2 and A-O3 oil, and Seiko S-3 grease. The Moebius was just too pricey to buy this early into the undertaking, when added to the cost of the other tools I've bought. Screwdrivers are Kwong Yuen for now, but I took the frequent advice on tweezers and bought Dumostar 3C and will probably add more DuMont later. I'm looking forward to making a start. I'll need a watch to work on, so I'm trying to line up an auction purchase within the next week. I've been mostly looking at Seiko and Citizen, and will perhaps a Seiko Crown if I can land one at a decent price.

      I tried pushing to dome the washer in and had no success, but stuffing it full of o-ring gaskets worked much better than I expected. It takes some pressure but not as much as you might imagine, but it does take patience ... and a couple of dozen small gaskets. I used the pendant tube of a watch case to stuff the gaskets in as I didn't have a way to machine a tool to suit.
