Clutch Pressure Tap (1) Remove front and rear propeller shafts (para 9-2). (2) Position drain pan under pressure tap. (3) Remove pressure tap plug and preformed packing from clutch pressure tap indicated by the sub code. Refer to Table 2-29. Clutch Pressure Tap. (4) Connect tube to boss adapter, hose, and pipe to tube adapter to clutch pressure tap. (5) Start engine (TM 9-2320-365-10). (6) Perform STE/ICE-R Test #50 (TM 9-4910-571-12&P). (7) With parking brake applied, make shift indicated by sub code. Refer to Table 2-29. Clutch Pressure Tap. (8) Accelerate engine until WTEC II TEPSS displays denied range. Refer to Table 2-29. Clutch Pressure Tap. (9) Maintain sufficient engine speed to keep desired transmission range while assistant notes reading on STE/ICE-R. (10) Let engine return to idle. (11) Shift WTEC II TEPSS into neutral. (12) If one or more clutches failed to indicate proper pressure, notify DS Maintenance. If all clutches indicate proper pressure, replace WTEC II TEPSS (para 8-2). (13) Shut down engine (TM 9-2320-365-10). (14) Remove pipe to tube adapter, hose, and tube to boss adapter from clutch pressure tap. (15) Position preformed packing and pressure tap plug in control valve module. (16) Tighten pressure tap plug to 84-120 lb-in. (9-14 N·m). (17) Remove drain pan under pressure tap. (18) Install front and rear propeller shafts (para 9-2). (19) Clear diagnostic codes (para 8-4).
