Fig. 69 - Pressing Pump Shaft Out of Pulley Inspection NOTE: If the water pump is being rebuilt due to normal wear which has occurred over a long period of operation, it is recommended that a complete new repair kit be installed. The kit includes the shaft and rear seal assemblies, impeller and other parts normally required to assure the customer further dependable pump operation. Fig. 71 - Pressing Water Pump Shaft and Bearing Assembly Out of Impeller and Body 1. Carefully clean and examine parts. Rotate shaft within bearings to determine amount of looseness present and for smooth, free rotation. 2. Examine the impeller blades and the hub which contacts the seal seat. Hub contact face must be smooth and not pitted or scored. 3. Check pump body for cracks, damaged or serious corrosion. Replace parts that are damaged, worn or appear questionable. Reassembling the Water Pump 1. Apply a light coating of sealing compound around the outside brass portion of the rear seal. Then carefully press it into body using a piece of tubing or a socket which has the same diameter as the brass cup. Make sure seal is fully located and that there is no trace of sealing compound on the face of the seal. Refer to Fig. 72. Fig. 70 - View of Snap Ring Securing Shaft and Bearing Assembly 2.

The clutch used in the MF 1100 and MF 1130 Diesel Tractors may be either' a single disc or a dual disc type. Diesel Tractors prior to transmission Serial No. DU 5466 except for DU 5215 through DU 5218 and DU 5255 through DU 5258 used a single disc type of clutch. Tractors after these transmission serial numbers use a dual disc type clutch. However, due to a kit which was made available by the service department, some of these earlier tractors may have a dual disc type clutch installed. All gasoline model tractors use a single disc type clutch. SPLITTING THE TRACTOR To split the tractor, proceed as follows: 1. Remove hood assembly. NOTE: On tractors with factory installed cabs, it will be necessary to remove front panels from the cab before removing the hood. 2. Remove the front cap section of the hood. 4. Remove left side panel below battery support. 5. Remove two capscrews securing battery support and priority valve support to rear of engine. 6. Disconnect all lines and wires between the engine and instrument panel. 7. Place wedge blocks between front axle and frame to prevent tractor from tipping. NOTE: On Tricycle Tractors, it will be necessary to support the front end from above to prevent tipping. 8. Disconnect oil lines at front of tractor, and remove retaining clips. 9. Place suitable jacks under engine and transmission. 10. Remove bolts securing transmission to engine. 11. Carefully roll engine forward away from transmission. At the same time hold out and upward on oil lines as shown in Fig. 1. 1

Testing - Refer to Part 9 Hydraulic System Component Performance Tests and Adjustments Removal.... Installation.... Disassembly.... Reassembly.... PTO CONTROL VALVE.... Testing and Servicing - System Refer to Part 9 Hydraulic Page Modulation Test.... PTO HOUSING AND REAR SHAFT Power reaches the PTO gear housing thru a series of shafts. The first shaft is splined to the engine flywheel adapter and extends the length of the transmission, thru the hollow transmission mainshaft. This first shaft is retained by a snap ring at the front of the transmission input housing. The engine must be separated from the transmission to remove this shaft. A coupler connects the first shaft to the intermediate, short shaft. This shaft drives the outer case of the PTO clutch. The coupler can be removed after transmission-center housing separation. The shaft must be removed from the rear, after the rear shaft has been removed. The rear shaft is connected to the PTO clutch by a sliding coupler and drives the gear train in the PTO gear case. This shaft must have end play, after installation. Tractors with ground speed PTO have a gear instead of a coupler that connects either the PTO clutch or the gear on the pinion shaft to the gear train. The center housing must be separated from the transmission to remove the fixed splined coupler. Separate the engine from the transmission to remove the forward drive shaft and the flywheel adapter. The remaining parts of the PTO assemblies can be removed after the top cover and PTO housing are removed. Refer to "PART 9 - HYDRAULICS, for hydraulic testing procedures pertaining to the PTO.

SERVICING THE HYDRAULIC COMPONENTS Information under this major subject heading pertains to removing, disassembly, inspection, repair and reassembly, and reinstallation of the hydraulic valves, pumps and filters. Adjustments to a particular component may be necessary upon reinstallation. Refer to the appropriate subheading when directed. Before attempting to repair any of the hydraulic components, first determine that repair is necessary by performing the appropriate tests on the suspected component. - '_BOLT I_SPRING' -C-FLAT WASHE-R C-SEALING GROMMET ELEMENT PLATE Fig. 14 -Intake Screen location_ RESERVOIR OIL FILTER The reservoir oil filter is also the dual charging pump's intake screen and is secured within the center housing, as shown in Fig. 14. When removing the screen for servicing, drain the oil from the transmission case and center housing prior to removal of mounting plate. When reinstalling the filter screen, always use new seals. Change the Reservoir Oil Filter as Follows: 1. Drain oil from transmission and center housing. Refer to Fig. 14. 2. Remove the bolts securing plate to tractor and lower plate with filter element attached. Fig. 15 - Filter Element Removed from Mounting Plate 3. Remove the old filter element from the plate and replace with a new one. See Fig. 15. 4. Secure new element to m 0 u n tin g plate and reinstall the complete assembly into center housing. - 5. Rei n s tall drain plugs (using new seals) and refill tractor reservoir to proper level. Service refill capacity of the reservoir is approximately 17 gallons (U. S.). Check for leaks. NOTE: Use only MF M-1127 oil. FRONT COVER ASSEMBLY The front cover assembly serves as the mounting for the pressure regulating valve and "charging" pump. It also contains the - 22 -
TESTS AND ADJUSTMENTS Determine which component or circuit that is desired to test and/or adjust -- then consult the sub-index below for reference to the appropriate test or adjustment procedures (i. e: lift links malfunctioning -- see "Linkage Control Valve Tests and Adjustments"). If unable _ to determine which area should be tested, refer to the "QUick-Check Procedures", the "Charging Circuit Tests and Adjustments", and/or the "Radial Pump Performance Test". In most cases, the tests should indicate the malfunctioning circuit and direct you to the trouble area. At that time, the specific tests should be performed. The sub-index lists the various tests on the components by the major circuits into which they are installed. Specific components tests may be found by referring to the first indented line in the sub-index.

TROUBLE-SHOOTING Determine which of the malfunctions or series of events is occurring and consult the sub-index (under this heading) for reference to the possible cause and correction. ;~' Accurate trouble-shooting requires five basic steps: 1. Becoming aware of the trouble. (This is usually through complaints of tractor operating malfunctions. ) 2. Gathering information. (This step requires the service personnel to become completely familiar with the operation and function of the various system components (so as to obtain a clear understanding of the system) and also to perform the preliminary tests necessary to obtain the "trouble symptoms" in the tractor. ) 3. Listing possible troubles. (After gathering the information obtained by tlie preliminary tests, and having a clear understanding of the system, it is helpful to list the possible causes of the trouble. In this way, it is less easy to forget some of the possible causes during later steps of trouble-shooting. A study of the various circuits and a list of the components that could possibly cause the malfunction tl) give all of the "symptoms" observed will prevent overlooking the unit causing the trouble.) 4. Checking POSSible troubles. (Perform the appropriate tests on the possible trouble areas while remembering to never take things apart unless absolutely necessary and checking the easiest things first. ) 5. Reaching a conclusion. (Through appropriate test procedures and process of elimination, the malfunctioning component should be easily isolated. But before attempting to repair or replace the "suspected" trouble unit, prove that your conclusion is correct. In some cases, a leakage test is necessary and perhaps the list of possible trouble causes was incomplete. ) When trouble-shooting, do not jump from observation to conclusion, but eliminate the possible causes one-by-one until there is no doubt as to the malfunctioning component.
