Description

Piston block or piston stop tool for chainsaw using Bosh WSR6F, Champion RCJ6Y or NGK BPMR7A type spark plug. It allows you to immobilize the piston in the cylinder in order to remove the clutch disc. This tool is equivalent to the Stihl piston block 1107 191 1200, 1107-191-1200 or 11071911200. As you can see from one of the photos, I broke my plastic Stihl tool, hence this realization. The version proposed here is a reinforced version using a CHC BTR through screw. A TF countersunk screw may also be suitable. I recommend a 100% PET print for greater strength. The first screw may be quite hard depending on your print quality: put a small drop of oil to help. 3 STL files are provided in relation to the screws you will have in stock: - M6 x 35 mm - M6 x 40 mm - M6 x 50 mm History: 12/02/2023 - First version
