SCREW

Diagnosing fasteners not holding can come down to one worn component—Screw (part 03-1645-01) is a common replacement item. Hardware wear is often visible: elongated holes, stripped threads, or parts that won’t stay tight. Use part number 03-1645-01 as the primary identifier, compare the replacement to the original, and install with careful alignment and routing. Once the root cause is corrected, performance should stabilize and output should return to normal. Replace this part when you see fasteners not holding, visible damage, cracks, corrosion, stripped fasteners, or a component that won’t stay seated. A solid approach is to confirm the symptom, then check mounting points and adjacent connections for contributing issues. If the part interacts with water, do a leak check during the first run and again after a short operating period. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces.
