Robust Pull Plate For Chenyu Chainsaw Starters

A purpose-built starter pull plate compatible with Chenyu MS261, MS271, and MS291 models. Measuring 85 mm in diameter and weighing 120 g, it utilises a proven combination of high-yield steel for load-bearing structures and thermally stable polymer for housing and guide features. Every contour—from rope groove depth to mounting bolt pattern—is validated against original equipment drawings. The plate undergoes multi-stage quality verification including visual inspection, functional pull-testing, and dimensional sampling. Its design accommodates typical operating stresses: repetitive manual pulling force (up to 18 kgf), ambient temperature swings between -5°C and +50°C, and exposure to organic debris and fuel vapours. Recommended for regular maintenance intervals or immediate replacement following starter cord failure, recoil spring fatigue, or physical damage to the original pull plate.
