M033 955 804 Important : The test requires detailed specialist knowledge and conscientiousness.The fitter must be responsible for the decision as to whether the parts needs changing or not. 1. Housing and housing cover 1.1 Cylinder bore. Max. wear dimensions of the bore diameters for honing: 8033/M033 = 78.055 mm 8043 = 101.56 mm 1.2 Threads 2. Piston* 2.1 External diameter 2.2 Gearing (crack testing longitudinally and laterally with a suitable testing procedure such as ferro flux). Scrap all parts with cracks. Remove any burr (ridges) on the sides of the gearing. 3. Sector shaft 1.Teeth (crack testing, longitudinally and laterally, with suitable testing procedure, e.g. ferro- flux.)
