It contains "bench servicing" instructions for the transmission... after it has been removed from Tractor. Many of the service procedures may be performed WITHOUT complete removal of transmission assembly... refer to "Service Information" for more details! SERVICE INFORMATION The service procedures within this Part pertain to a-speed and Multi-Power transmission assemblies. Although these transmissions differ in construction (and servicing) their removal from Tractor is basically the same. 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 of IPTO pressure regulating valve (or Multi-Power shift control valve, if equipped) and engine clutch release bearing. Dual range planetary and shift rails (and forks) may be serviced by separating Tractor between transmission and center housing. This "split" will require removal of operator's platform and shift cover (for access to hydraulic line for IPTO or Multi Power shift valve). See Figs. 1 and 2. The main shaft with related gears and bearings may be serviced after shift rails and planetary have been removed. With main shaft removed... reverse idler gear assembly may be serviced. For servicing of main input shaft, countershaft and PTO lower (front) shaft or hydraulic clutch pack (on Multi-Power Tractors)... complete transmission assembly should be removed from Tractor. (Removal of main input shaft requires moving main shaft rea'rward.) NOTE: After servicing and reinstalling Multi Power transmission, place Multi-Power control in "High" position before starting engine. (This will insure that transmission bearings are initially lubricated.)

Fig. 30 - Removing/Installing Snap Ring Located at Rear of Front Bearing (on Main Shaft) f. Remove rear snap ring (for front bearing) from shaft as showniin Fig. 30. g. Remove majn shaft rearward from case while also removing;;sliding gears upward from case. 2. Check gears, main shaft splines and bearings for excessive wear (or damage). 3. If main shaft inner bearing (see Fig. 31) is to be replaced... use a suitable press plate and driver handle to install new bearing to the depth of counterbore in shaft. See Fig. 32. 4. If rear bearing is to be replaced, front snap ring is to be removed and old bearing must be pressed off front of mainshaft (needle bearing end)... new bearing is pressed onto front of main shaft with bearing's outer snap ring toward rear of shaft. See Fig. 33. Fig, 32 - Installing New Bearing Into Front of Main Shaft 5. Reinstall main shaft, related gears and bearings as follows... see Fig. 33: NOTE: Countershaft. reverse cluster gear, PTO lower shaft and main input shaft should be installed before installing mainshaft. a. Check that inner bearing (at front of main Fig. 31 - Main Shaft Inner Bearing - Shown Installed Fig. 33 - Main Shaft Relationship of Gears and Bearings NOTE: The 2nd and 3rd gears will be 2nd and 4th on some Tractor applications, but relative size of gears will be similiar.. -10- CS-17 1 ST ISSUE

Certain areas of transmission may be serviced by separating Tractor between engine and transmission or between transmission and center housing... refer to "Service Information',' heading which includes information pertaining to different Multi-Power transmission assemblies that may be encountered. *NOTE: "Change" information and procedures included under these subjects in this issue (2nd). SERVICE INFORMATION The 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 access to Multi-Power shift control valve (its linkage) and engine clutch release bearing. See Fig. 1. NOTE: Removal of MAIN INPUT SHAFT requires removal of main shaft. The dual range planetary, shift rails and forks may be serviced by separating Tractor between transmission and center housing. This "split" will require removal of step plate, sheet metal and shift cover (for access to hydraulic line for multi-power shift valve)... see Fig. 2.

7. Dual range planetary may be either "standard duty" or "heavy-duty" type. If "standard duty", width will be 1.720"/1.723"... if "heavy-duty", width will be 1.942"/1.945". Two diffe.rent "heavy-duty" types may be encountered. One will have a round 0.0... other will have squared sides with rounded corners. Service procedures for planetaries will be SIMILIAR... exception being an external retaining ring securing pinion shafts in "heavy-duty" types. SPECIAL TOOLS NOTE: Cut-away portion of rear cover plate is to be located so that it is over bottom righthand mounting bolt, if "standard-duty" type. This cut-away (or slanted portion of rear plate) is to be over bottom left-hand mounting bolt if "heavy-duty" type. Bottom left-hand mounting bolt WILL NOT use a lock washer on EITHER type planetary. Some special tools are required for proper servicing. All special tools are used (where applicable) in compiling the "Repair Time Schedule". These special tools are listed in Chart I.

All parts removed should be thoroughly cleaned and air-,dried. If complete disassembly is performed... case should be cleaned and dried. NOTE: Use a suitable cleaning solvent. Do not wipe parts (or case) with a material that leaves lint. DO NOT SPIN BEARINGS WITH COMPRESSED AIR. 2. Inspect all gears for chipped (or broken) teeth. Backlash between new mating (meshing)gearsshould be.002" to.008". 3. Check all bearings for binding, rough spots... and excessive wear. 4. Check shaft splines for damage, or excessive wear. 5. Inspect thrust washers and spacers for wear and scoring. 6. Replace all seals with new items. 7. Check spool in shift control valve assembly for damage... or exdessive wear. Also make sure spring is not broken and use a new copper washer.(on correct mounting bolt)... plus a new mounting gasket. CS-29 2ND ISSUE

Inner shaft is driven by a hydraulic clutch and drives outer shaft through an idler gear on pinion shaft. Hydraulic clutch is directly driven through the Ferguson pump, transmission and engine clutch cover. This provides Independent Power Take-Off (IPTO). Auxiliary hydraulic pump, located in front of Ferguson pump, provides oil for clutch operation. Special tools shown in use are as follows: FT 357... Seal Protector MFN 768...

TESTING AND TROUBLE-SHOOTING Test and trouble-shoot the system before disassembling components. Checking System Pressures The system's main relief valve is located inside reservoir area of engine driven steering pump. 1. Check main relief valve setting as follows: a. Connect a 2000 psi gauge (minimum capacity) to supply line between engine driven pump and steering control unit... see Fig. 1. b. Check that reservoir oil level is correct... then run engine at moderate rpm and cycle steering wheels fully in both directions while observing maximum reading on pressure gauge (when wheels hit their stop). CONCLUSION: Pressure reading should be 1500-1600 psi. A reading other than this indicates that system's relief valve needs adjustment... or replacement (refer to Step #2 for adjustment procedures). If pressure is correct either return system to its normal operating condition (remove gauge, etc.), OR check for excessive pressures in lubrication lines between steering rack and pump. 2. If relief valve requires adjustment, or replacement... proceed as follows: a. Note aligning marks between reservoir and pump body... see Fig. 2. b. Remove reservoir from pump. Oil will drainl c. Loosen lock nut on relief cartridge and turn adjusting screw (clockwise to increase, counterclockwise to decrease) until recommended setting is obtained. (Several attempts may be necessary Fig. 1 -Checking System Main Relief Valve Setting Fig. 2 - Reservoir and Pump Body Aligning Marks MF 1085 - FRONT AXLE AND STEERING
