Servicing of the Pneumatic Air Starter
This task provides instructions for servicing the starter with oil and draining the starter of oil. There are two methods that you can use to fill the starter with oil:
(a) The preferred method is to use a tool in the magnetic plug housing to pressure fill oil to the starter. This method is used after you install the starter on the engine.
(b) The alternative method uses the oil fill plug to gravity fill oil to the starter. This method is used before you install the starter on the engine.
