Starter bush in bellhousing

1
Ken,
 
I haven't actually eyeballed one of these bushes for a very long time but, from memory, they are sintered bronze (which is very porous) and are boiled in oil at the point of manufacture.  As Phill points out, all they need is the very occasional drop of oil.  Since the starter only runs for a few seconds per start and not many times per day, the original oil usually sees out the life of the vehicle.  It is prudent, however, to add a bit of light oil whenever the bush is accessible, as when the starter is out for service. 
 
These bushes can wear out and the replacement should be (again if I remember correctly) oil-filled sintered bronze.  As Phill says, new or reconditioned starters will come with a bush; it is completely silly not to change the old one and grease should never be used.

A problem with this bush is when people change the starter motor, they grease the shaft/bush. This is a bronze bush which needs to be oiled. Grease kills it real quick! A friend of mine was changing the bush yearly on his Kombi until told him not to grease. He never changed it again.

Old auto electricians used to have jars with the bushes in them with oil. I was always taught to leave them immersed in oil overnight before using.

An even better treatment (and quicker) is to immerse them in a high quality oil and heat the container.  Stop before the oil begins to fume.  Take away the heat and wait until the oil is back to ambient temperature.  This process agitates the oil still in the bush and mixes it with the new oil.  As the oils cools, oil is drawn back into the bush, ensuring that it has achieved maximum oil retention.
