There are always discussions regarding what part broke and I thought it would be nice to have a visual for those (including myself) that do not know exactly what part is being discussed.
With everyone's past experience maybe we can use this illustration to point out the problem part and add a brief description of the failure type (IE cracked,sheared,distorted) and at what power level.
I've pointed out a few and with everyone's help we can number and list parts known to be a problem.
Calibration failures could be listed too (IE low/high pressure damages this particular part)
1. Stator support
Splines strip
2. Selective pump washer
Small cracks can develop causing it to break/fall out. Will lead to damage of stator support retaining bolt due to metal to metal contact
3.Turbine/Input shaft
(failure type/description needed)
4. Over Drive ring gear
Cracks in spline area. Blocked 4th accumulator mod thought to be a possible cause.
(failure type/description needed)
5. Band pin
Shears off causing band to become inoperable.
6. Band
Lug area (where band pin attaches) can be damaged/torn off.
Apply end can be punctured by servo pin.
7. Direct piston
Distorts under high apply pressure.
8. Forward drum
Shaft shears
