Turn cover over and drive out retaining pins, Fig. 15. INSPECTING DUAL CLUTCH 1. Inspect all parts for wear or damage. Replace as needed. a. Flywheel friction face or clutch primary pressure plate may be resurfaced within reasonable limits, providing same amount of material is removed from clutch mounting surface on flywheel. Fig. 14-Removing Lower Pivot Pin b. Original distance between clutch mounting surface and friction face on flywheel is inches. Check this dimension whenever new pressure plate or clutch assembly is installed. 2. Correct coil spring color code is violet. a. Compressing each coil spring to inches should give a 14 ± 6.7 lbs. load. b. Free length of new spring should be inches. c. Replace insulating washer each time a spring is replaced.

These instructions are filed under this divider... and are identified by their CS number printed in the lower right-hand corner on each odd numbered page (beginning with a Page 1). SERVICE INFORMATION Many of the service procedures may be performed WITHOUT complete removal oftransmission assembly from Tractor. It will require good judgement by the serviceman as to necessity for complete removal of transmission while considering the extent of servicing to be performed. 1. The following information pertains to 8-Speed Transmissions: a. Although reference service publication CS-17 shows a regulating valve installed on input shaft retainer... this valve is not used in this Tractor application. Also the supply line shown routed through transmission case is not installed. The brake cross shaft shown through front of case member (beneath clutch release bearing) is not installed in this location for this Tractor model. However, these minor variations will not affect BASIC servicing. b. Main input shaft retainer and PTO input shaft (with their related seals and bearings) may be serviced by separating Tractor between engine and transmission... this "split" will also allow servicing engine clutch release bearing. c. Dual range planetary may be serviced by separating between transmission and center housing. If shift cover is removed after this "split" MF TRANSMISSIONS
