"On all latest machines shipped from the factory, the two grease tubes Y7, Fig. 153 have been eliminated.
The motor requires no lubrication."
I gather that you do not have a manual that came with your particular machine.
Hi
Thanks for the response. The original manual wasn't with the machine so I purchased a PDF of the manual for 15K110, 15K111 and 15K112 (mine is the 15K112; solid handwheel and belt drive electric motor). There's all the usual stuff in the manual plus some more detailed bits on taking the tension and shuttle race apart for cleaning.
The links you sent are interesting and useful. Funny that Singer suddenly went lube free on these motors after years of selling tubes of grease. It's one thing to say that the motor requires no lubrication but I wonder, if after 61 years, it would appreciate so petroleum jelly in the bearings. It's looking like I might have got get inside this one to see if I can getting running more quietly. Has anyone ever tried sourcing and replacing bearings on a noisy motor?
Regards
