3.12.1 PLATE TEMPERATURE MEASUREMENTS (See Section 3.12.3.3 prior to machining holes for thermocouples.) Temperatures are to be measured for plates 1 and 3 (see Figure 1) 1) with type J thermocouples or similar temperature measuring devices (TMD). One thermocouple is to be located in each steel plate. The holes are made using electro-discharge machining (EDM) or other suitable technique, are 0.58 mm in diameter and located at mid separator plate thickness. The holes are 13 mm deep from the root of the spline tooth to place the thermocouple junction at the mean friction radius and are placed at the 12 o'clock position in the test head. The TMD should be fitted to touch the bottom of the manufactured hole for good thermal contact and cemented to prevent movement during plate insertion or during testing.

3.12.3 ASSEMBLY PROCEDURE 3.12.3.1 Inspect rotating shaft seal for deterioration and replace if necessary. Indication of seal seal failure or loss of flexibility is the escape of air past the seals. If this seal is replaced, also rep replace lace lip seals. 3.12.3.2 Install clutch plate hub, snap ring, ring, and clutch plate retainer. 3.12.3.3 Inspect clutch plates prior prior to testing using the following procedure before the plates are machined for thermocouple installation. A. Find the thickest spot of each plate and arrange the plates so the thick spots are distributed around the pack. B. Identify each plate by marking the top tooth with a number, one one through six, in the sequ sequence ence shown in Figure 1. The number on the steel plates is to be put on the rounded side. This number will be at the top and facing the cover when each plate is installed for test. C. Mark a tooth at approximately 120° 120° each way around from the numbered tooth on each plate. D. Measure and record the average overall pack pack thickness at three places (at the numbered numbered teeth, at 120° and at 240°) under a 14 kg load. E. At each of the three locations, 120° 120° apart, measure at two places, one near the inside, and one near the outside diameter. These measurements will be labeled "initial". F. Use a micrometer and keep the entire anvil within the friction contact area for each measurement. G. Following completion of the test, repeat the measurements in steps D, E and F in the same order and at the same places, beginning at the numbered tooth. These measurements are labeled "final". H. Subtract the "final" measurements from the "initial" measurements. Wear limit at any of the six places is 0.152 mm. Average wea wearr per plate is not to exceed 0.076 mm. 3.12.3.4 Presoak clutch friction plates in candidate test fluid for 5 minutes minimum and then install clutch plates in the test head in the order prescribed with plate number facing the cover. 3.12.3.5 Install plates into test head. The sump thermocouple is to be located at the midpoint of the back-to-back back-to-back plates of the pack. 3.12.3.6 Install two spacers only between the cover cover and the outermost clutch plate in order to locate the sump thermocouple at the center of the test pack. 3.12.3.7 Check clutch plate plate pack free movement. Clearance is 0.70 ± 0.13 mm. This measurement, made with a depth micrometer, is made between the head and outermost clutch plate while the pack is pressed into the head with finger pressure (about 1 kg) at the sites of measurements. 3.12.3.8 Install sump thermocouple between the 4 and 5 o'clock position to within 1.0 mm of steel clutch plate annulus O.D. (without touching clutch plate). 3.12.3.9 Install new O-rings on cover, cover, if necessary. 3.12.3.10 Attach cover and fasten with cover retainer. 3.12.4 LUBRICANT INSTALLATION 3.12.4.1 Attach line tovalve housing port11ato'clock 12 o'clock position.

This test is run on a modified SAE #2 machine with a variable speed drive system capable of producing stable torque values in 1-300 rpm range and 680 Nm torque, a pump with a variable fflow low rate of 1.5 to 2.3 liters per minute, and a fixed fluid capacity of 300 ml. Run one pack at the conditions described below. A pack consists of two steel separator plates and one friction plate (see Figure 3). 3). The friction plate is rotated during the test and the separator plates are stationary. The driving splined hub is sealed at the O.D. to force all flow of pumped fluid across the faces from the center of the hub and through the grooves of the friction material. All packs will be run a after fter receiving a 30-minute break-in per per procedure in Table V. V. Torque and speed conditions are interactive and a feedback system must m ust be in place.

Temperatures for plate 1 and 3 (see Figure 3) t ype J thermocouples or similar 3) are to be measured with two type temperature measuring devices (TMD). Two thermocouples are located in each steel plate, 180° apart. The holes are made using electro-discharge machining (EDM) or another suitable technique, are 0.58 mm in diameter and located at mid separator plate thickness. The holes are 13 mm deep from the root of the spline tooth to place the thermocouple junction at the mean friction radius and the thermocouples are placed at the 3 and 9 o'clock position in the test head. The TMD should be fitted to touch the bottom of the manufactured hole for good thermal contact and cemented to prevent movement movem ent during plate insertion or during testing. - Refer to 3.12.2. 3.12.2. 3.13.3 CLEANING PROCEDURE PROCEDURE 3.13.4 ASSEMBLY PROCEDURE 3.13.4.1 Inspect rotating shaft seal for deterioration and replace if necessary. necessary.
