شوكة، عمود ذراع التشغيل

Replacing the old drive lever shaft fork on my SC4 was straightforward — the pivot points lined up exactly with no filing needed. It’s a solid chunk of metal, and the fit feels precise where it engages the lever. Saved my bench lathe from sitting idle.

Had a small issue with the old fork binding on my SC4 lathe, but this one slid right onto the drive lever shaft without any fuss. The machining on the inner bore is spot-on for the replacement.

Exactly matched the SC4-158 part number on the diagram, so I had no confusion during installation. The metal feels sturdy and the fork slots lined up perfectly with the drive lever shaft assembly.
