(1) Torque for seven bolts and nuts ... 1800 200 N m (1330 150 lb ft)(2) Torque for four bolts and nuts ... 1350 175 N m (1000 120 lb ft)(3) Torque for two bolts ... 1350 175 N m (1000 120 lb ft) Collet Removal ToolsCollets (1) use 5P-5265 forcing bolt.Collets (2) & (3) use 5P-8715 forcing bolt. For correct pin and collet installation and removal procedures, refer to the relevant section in R2900 L.H.D. Vehicle Systems, Disassembly and Assembly, Form No. RENR4582 (9EL3678).Pin and Collet Installation
1. Clean all collets and pins.2. Clean the bores for all collets and pins.3. Apply 7M-7456 Bearing Mount to bores before seal installation.4. Put 5P-960 Lubricant on the pin bores before assembly. Put 5P-3931 Anti-Seize Compound on all collet fastening bolts.5. Collets and pins must be centered axially. Installation Procedure for Collet Assemblies (1): 1. Install the pin, collets, bolt and nut as shown in the illustration. The collet on one side must not extend farther than the other collet when the bolt and nut are tight.2. Tighten bolt (4) and nut (5) evenly to a torque of 1800 200 N m (1330 150 lb ft). After the bolt and nut are tight, hit the collet on each side with a heavy hammer until the torque on the bolt and nut is less than 950 N m (700 lb ft).3. Tighten the bolt and nut again to a torque of 1800 200 N m (1330 150 lb ft). Hit each collet again until the torque for the bolt and nut is less than 1600 N m (1180 lb ft).4. Tighten the bolt and nut to a final torque of 1800 200 N m (1330 150 lb ft).5. An optional method of installation can be used.6. Install the pins and collets as before. Press the collets on the pins with 535 kN (60 ton) of force. Tighten the nut and bolt to a torque of 1800 200 N m (1330 150 lb ft). 50 service hours after any pin and collet was installed, tighten the bolt and nut in each collet assembly to 1800 200 N m (1330 150 lb ft). Installation Procedure for Collet Assemblies (2): 1. Install the pin, collets, bolt and nut as shown in the illustration. The collet on one side must not extend farther than the other collet when the bolt and nut are tight.2. Tighten bolt (6) and nut (7) evenly to a torque of 1350 175 N m (1000 120 lb ft). After the bolt and nut are tight, hit the collet on each side with a heavy hammer until the torque on the bolts is less than 680 N m (500 lb ft).3. Tighten the bolt and nut again to a torque of 1350 175 N m (1000 120 lb ft). Hit each collet again until the torque for the bolt and nut is
