(b)
Lubricate the new packing (4) with the engine oil.
(c)
Install the packing (4) on the starter drive shaft.
(d)
Apply a thin layer of grease to the splines of the starter drive shaft.
CAUTION:_______DO NOT LIFT THE STARTER BY THE DRIVE SHAFT. INTERNAL DAMAGE TO THE STARTER CAN OCCUR.
(e)
Move the starter (2) to the main gearbox.
1) Carefully move the starter forward until the splines on the starter drive coupling and the starter drive shaft engage.
(f)
Align the index pin on the QAD adapter with the index hole on the starter flange. 1) Carefully move the starter (2) forward until there is no
separation between the starter and the QAD adapter.
