Sonnax turbine-side stator bearing spacer AL-WS-3 along with AL-N-2 thrust bearing allows rebuilders to retrofit the worn or damaged OE bearings in Allison 1000/2000/2400 early converters.
When installing stamped version AL-WS-3, ensure the bearing spacer is seated flat on the mating machined stator mounting surface. Due to die-cast stator slot variations, it may be necessary to rotate the bearing spacer into adjacent slots until spacer tabs fit freely and bearing surface is flat.
When using AL-WS-3, machining of the stator is always required.
