Chain

The challenge associated with driving the compressor using two different spec sprockets continues. The information I received from Saeco regarding the sprocket dimensions was short sighted. While the sprockets have the same pitch, the roller diameters are too far out of spec. 

The existing sprocket is American Standard ASA 41 and the new sprocket is Briitish Standard 08BI. The roller width on the 08BI chain is far too wide and causes it to bind on the engine crank case. Instead the original ASA 41 chain will be used and cut to length and a half link added to get the correct length. In order to make the 08BI sprocket work, t it will be machined down from the 7.75mm roller width to the 6.25 width.
