I recently purchased a Boley Leinen Reform Lathe and in my research I discovered that there recommendation for freeing up the spindle is to add benzene or fuel to the oil wells on the top. Is this OK and what would the process be? Hear is the Lathe and Vintage instructions. Sent from my iPhone using Tapatalk Pro

One problem with the Omega database is the same as other watch companies they don't list the old stuff typically. So as pointed out above Omega does have a parts list for the 552. They don't though have a service guide specific 552. Conceivably they never had a service guide for the 552 because usually refer you back to the base calibers. So for instance first link below lists all the variations. Then usually I've had a really good luck with googling finding tech sheets. Although I did get Several hundred megabytes of Omega tech sheets off of eBay. Then googling second Link for instance they have tech sheets. Go to Omega section scroll through far enough third link. Then if you photograph the case back parts the you're not sure about on Monday I will ask the other watchmaker he specializes in the Omega watches he might have an idea. I looked on the Omega database at work there was zero reference to the case number I'm guessing it's too old. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Omega_552 http://guides.mccawcompany.com/ http://guides.mccawcompany.com/downloadable/download/sample/sample_id/920/

Hi Dan, Well done and good wishes for the watch repairs. Look up Mark Lovick, he is the guru. Mark is on u tube and he runs watch repair courses. I would do it but I am 75 now. I use Practical Watch Repairing by Donald de Carle for info:. Great book. Still using it for reference..Best regards, Mikie.

With the cock removed (as in your video) there will be a lot of play as the jewel that supports that end of the pinion is in the cock. Also, I can't see any sign of the tension spring in any if the images. The specific function of that spring is to control seconds hand stutter so without it there will be a problem. You mention that without the cock the spring sits up in the air above the pinion, which suggests that the spring isn't actually missing, but it also suggests that the spring should sit underneath the pinion leaves so that it lifts the pinion up into the jewelled bearing in the cock thus providing the tension to control the seconds hand. I have not worked on one of these so I don't know if the spring should lift the pinion up or press it down, but either way it needs to be in contact with the pinion.
