(a)
Remove the four bolts and washers that attach the oil pump to the main gearbox.
(b)
Two of the four oil pump flange bolt holes (where you just removed the bolts) have threads. Find the two threaded holes and install two PWA 86630 or PWA 88774 jackscrew pullers.
NOTE: If you can not find the two threaded bolt holes on the
____ oil pump flange, you can not use the two PWA 86630 or PWA 88774 jackscrew pullers to remove the oil pump. To remove oil pumps without threaded bolt holes, carefully pull on the pump to remove it from the gearbox.
To get the two threaded bolt holes in the oil pump flange, see Sundstrand Service Bulletin 5008437-79-4.
