Need to change relating chains, sprockets and bearings on a 2 stage Gemini jack installation, installed about 2004. 3500 pound car, 18 feet of rise. I am in need of a source to buy the idler sprockets, anyone have a source and part number other than going OEM? Roller chain size is #50 which is readily available from several vendors. This elevator is in service, can't shut it down to pull a sprocket off for comparisons.
