Betsy came over yesterday with her Kenmore 158.882 Trispan. It is a lovely machine. The feed dogs don't drop and the stitch length varies. For comparison, to see how the feed dog drop worked, she got out my Kenmore 158.84. I had not worked on this machine since November of 2011 when I took it to the Ray White class.
I don't understand how the gear broke, but it was easy as pie to replace. I unscrewed three screws holding the whole piece in place and dropped the new one in. Ray had said something about timing the blind hem stitch cam or something. I cannot remember. I never got around to it. None the less when Betsy got it out, I decided to look at it.
I could not figure out what he meant. There did not seem to be any sort of adjustment necessary. So I just found a foot for it and fired her up.
She works very well. Quiet like all end loader Kenmores and strong. I tried one cam and it worked. I imagine the others will as well. It is a very nice machine for a beginner. I wonder if I still have the cabinet that it came in.
