Does this fit my product?Questions & Answers for Bump Knob
I need a bump feed knob for my trimmer. I ordered one from another company and received an Oregon brand part # 55-803 and it didn't fit. The bolt on my knob is 3/8" across, including the threads. The threaded part of the shaft is 1/2" with left hand threads. The head of the bolt is square. The plastic knob is around 2" across with 4 spots that are slightly raised. Is this the correct part for my Troy-Bilt string trimmer? Thanks

I had to order the spool assembly and the bump head know assembly. Since I had to cut the bolt off I had to replace the spool assembly which fastens onto the neck of the trimmer. Everything went together smoothly. I didn't have to use any tools to replace the Bump Head Assembly but the shaft assembly with the spool; I used a wrench and philips screwdriver to put it together.
