where ever a spindle protrudes and comes through the brass plates you give one spot of light oil this can be done using a plastic syringe and a needle (the sort you refill the printer cartridge with )that's what i use, as large as the working look they were fitted in through the back door then the striking ring. or the striking bar assembly fitted.
My Smiths Westminister chimes is 70 years old still going strong, i got it off my late gran hence the age this one is running in plain brass holes, (no mounted bearings around the spindles)
