Installation Procedure
1. Put the same alignment mark on the new crankshaftsprocket as in the old sprocket. Notice Check the timing chain, camshaft sprocket, injection pump timing sprocket, oil pump chain and oil pump sprocket for
wear and replace if necessary.
2. Install the new crankshaft sprocket (12) by using a drift (21). Notice Align the groove of sprocket and woodruff key (arrow)
exactly. Drift 116 589 07 15 00
