| Laminations tend with a coarse feed & leave tool marks clearly visible. The no for link cannot be seen on the worn side also. The use of cutting paste gives inward thrust result. Carburetters are a male of 20' taper a clear fit in the slot of the female cone. Filter Sinters contained A Main bearing for the free piston which has come into the Gearbox hoses. Not in but a heavy deposit upon one side all internal corrosion. It has a life about 3 times wherewitha provides an acid former in the oil. With the present triple grade oils, and aryl fuels the bearing alloys corrode away very quickly. At high temperatures & from about 400 miles, the acid content of the oil is found to be high, further in the oil which is up in processing now. Customer will not knowingly or wittingly use grade oils or old oil to which inhibitors have been added. This latter is not on the market. The problem is that for some people but perhaps not within our class of car. Silegt Luffelt. We have been experimenting with other fuels & we have come to the foregoing conclusion. | ||
