jmb Posted May 4, 2010 Report Share Posted May 4, 2010 I have some ETA 2671 movements that are missing hour wheels. I looked at cousins and discovered there are about 4-5 different height hour wheels! How do I determine which one I need? I'm assuming I need to measure the canon pinion height and maybe subtract the thickness of the gear on the bottom of the hour wheel or... Link to comment Share on other sites More sharing options...
ubiquitous Posted May 4, 2010 Report Share Posted May 4, 2010 J- In that lot of 2671s that you picked up, are some with hour wheels/pinions present? Or were all of them sent without these wheels? If there are some with an hour wheel fitted, it should be a fairly easy exercise to size one up and compare accordingly... Link to comment Share on other sites More sharing options...
jmb Posted May 4, 2010 Author Report Share Posted May 4, 2010 R - Yeah. The seller has already made an "adjustment" for the cost of hour wheels but every one is missing. I have gotten movements from ofrei that ship with the hour wheel and washer not installed. The seller seemed surprised and distressed that they were ALL missing and I am getting the impression that when he checked all of the ones he had on hand were in like condition.

RWG Technical Posted May 4, 2010 Report Share Posted May 4, 2010 If you go on the ETA website, you can download the tech data sheets for the movement. On the last few pages, is a listing of the various height combinations of hour and seconds posts and cannon pins. You have to remove your cannon pin, measure it, and find the cooresponding hour wheel that matches it. Lost hour wheels on loose movements is a common problem, nothing to hold them in place.

jmb Posted May 4, 2010 Author Report Share Posted May 4, 2010 Thanks, Zig! When measuring the cannon pin is it's height measured from the top of the small gear, top of large gear, or the entire assembly? Looking at the tech sheet I think I've got it figured out...

jmb Posted May 4, 2010 Author Report Share Posted May 4, 2010 I was able (under microscope) to measure dimension "E" (page 13) as 1.60 mm so reading across to the left I guess I need hour wheel with height of 1.56 mm! Of course, Jules Borel lists most of the hour wheels at $4.60 for three or more but THIS one is $6.40! At Cousins it's less than half that which will more than make up for the postage. Is it safe to assume that the "spring washer" comes with the wheel? Link to comment Share on other sites More sharing options...

Dial washers are normally not included, you can pick up a gross of them for a few dollars, worth having in your spares bins... Link to comment Share on other sites More sharing options...
jmb Posted May 5, 2010 Author Report Share Posted May 5, 2010 The washer is not listed in the data sheet I downloaded from Cousins, it is depicted in the drawings but not called out with a part number. I have e-mailed Cousins to clarify... Link to comment Share on other sites More sharing options...
kbh Posted May 5, 2010 Report Share Posted May 5, 2010 Better check Cousin's freight policy. I bought a couple of stem tubes and they would only ship to the US with signed priority mail. The shipping was about 8x the cost of the part. Link to comment Share on other sites More sharing options...

I have e-mailed Cousins to clarify... They do packs of assorted washers, I have one myself - http://www.cousinsuk...og/4/5/641.aspx Good luck with the email by the way, I find them slow to respond, if at all, to email. On the phone they're great. Link to comment Share on other sites More sharing options...
jmb Posted May 5, 2010 Author Report Share Posted May 5, 2010 Crap! They've already replied and told me to submit a "non-listed item request" request. Bright - Thanks for the link, that's what I really need - I ordered the "500 Assortment". kbh - I've ordered from them before but in this case the price difference between JB and them will make up for the stiff shipping charge... The shipping will be about $16 so I will still realize a significant savings and it will be like getting the washer assortment for free! I agree, Cousins is not the way to go for a small low-dollar order from CONUS. Thanks for everybody's help! Link to comment Share on other sites More sharing options...
