C. Removal of the Rotating Mating Ring Assembly
(1) Depending on the drive pad from which you remove the rotating mating ring assembly, get the applicable tool diameter configuration from the tool set, SEALOL AND MAGNETIC SEALS - R/I (856A3576G01).
- for the fuel pump and hydraulic pump drive pads, use the smaller diameter tool with the items P09, P10 and P11
- for the starter and IDG drive pads, use the larger diameter tool with the items P02, P03 and P06.
(2) Loosen the tool items:
- P06 and P05 (larger diameter tool) or
- P11 and P05 (smaller diameter tool).
(3) Engage the tool on the gearshaft until the nylon/viton-end of item:
- P02 (larger diameter tool) or
- P09 (smaller diameter tool) Comes against the polished face of the rotating mating ring.
(4) Tighten the item P05 by hand until you feel the jaws of the collet are tightly engaged under the mating ring. Manually give the tool one or two pulls to make sure it is correctly installed. If so, it must not come out.
(5) Install the slide hammer on top of the tool. Operate the slide hammer and remove the rotating mating ring assembly from the gearshaft.
