dbane883 Posted March 26, 2014 Report Share Posted March 26, 2014 Experts on 15xx please chime in. What is the official name of the bushing highlighted in the photos below. And what is the exact replacement part number? I think I need to replace this at some point. Link to comment Share on other sites More sharing options...
freddy333 Posted March 26, 2014 Report Share Posted March 26, 2014 That is the Driving Wheel (1530 (base caliber) part 7837), which looks like its pinion was broken off in the plate. Link to comment Share on other sites More sharing options...

So that "bushing" that I'm pointing to is supposed to be attached to the driving wheel?? Link to comment Share on other sites More sharing options...
automatico Posted March 26, 2014 Report Share Posted March 26, 2014 The bushing or jewel will be pressed into the plate. All 25 and 26 jewel models have a jewel at this location and 17 jewel models must have a brass bushing...I do not remember as I have not worked on a 17 jewel model in 15 or 20 years. Anyway...if there is anything in the hole, F333 is right, the 'intermediate wheel' pivot has broken off in the bushing. It looks like a regular 1530/70 jewel will fit in the hole in the plate and aftmkt intermediate wheels are A-Ok to use. The pn for the lower intermediate wheel jewel is 7919 and the upper jewel is 7918. Better supply houses should be able to cross the jewel pn over to actual size for replacement jewels. The intermediate wheel pn is 7917. You will need to find someone who is handy with a staking tool or better yet, a Seitz jewel setting press to r/r the bushing and replace it with a jewel. The Seitz tool is quite a bit more precise. Link to comment Share on other sites More sharing options...
