SEAL 3501795 - Caterpillar

Figure 161Install next friction disc followed by a steel disc in the same position as the second until all the discs are installed. The last disc must be friction. From the separator springs out, you start with a steel disc and end with a friction disc.
Figure 162Install three separator springs, one after the other, in a clockwise direction. Do not put a spring in the next channel. (See assembly instruction page.)Install three more springs in the following three channels. If assembly is correct, you will have three springs and a space and three more springs and a space. (See assembly instruction page.)
Figure 163Install last outer steel disc rotating disc clockwise one tooth from position of preceding steel disc. The teeth on this steel disc will be in the same channel as the very first steel disc installed and will cover the ends of the separator springs.
Figure 164Detail of Separator Spring Installation.
Figure 165After complete assembly of clutch pack and separator springs, compress clutch pack and springs and measure clutch pack again. Measurement must be within distance explained below.Measure the distance from the last steel (not as shown - as last disc must be a steel outer disc with teeth covering the separator springs) clutch disc to the outer face of the cable drum. This distance must be between 6.691 and 6.768 inches (169.9-171.7 mm). If it is more or less, make a check that the correct quantity of clutch discs are used. See the free spool clutch disc chart on the assembly instruction drawing. Install another steel disc as a shim to decrease distance, if necessary. If another steel disc is used as a shim, be sure the teeth on the steel disc match the teeth on the last steel disc installed and cover the ends of the separator springs.
Figure 166Install o-rings and lip seals on the clutch shaft and release plate. See Fig. 167 for the correct position of the lip seals.
Figure 167This is a view of the correct position of the lip seals.
Figure 168Install the drum release clutch piston on the clutch shaft. Do not install bore plug at this time.
Figure 169Position the inner and outer springs on the drum release clutch position. Put a small amount of grease in the split ring grooves to hold split rings after support is compressed.
Figure 170Install the cable drum support on the shaft. Align it with the timing mark as indicated in the drawing. Make a check that the springs are centered and are not on the raised bosses.
When assembled, the free spool clutch is under approximately 10,000 lbs (4.600 kg) of force. Use caution and follow these instructions when you assemble the clutch. Incorrect procedure will cause personal injury.
Figure 171Place the assembly in the press as shown. Put a cylindrical spacer inside the drum between the piston and the press bed. The spacer must be 2 to 2.5 inches (5 to 6.5 cm) thick and 7.5 inches (19 cm) in diameter. You can make it from hardwood or
