Assembly Servo Piston/ Dual Pump Housing Assembly Dual Pump Housing Assembly Step 10 Step 12 Step 1 Step 2 Thread a locking nut (item 8) onto the servo piston bolt until it fits against the spring compression nut. This step may require two people: Using a 5mm hex key, hold the servo piston bolt steady, then use two 9/16-inch open-ended wrenches to tighten the locking nut against the spring compression nut. The servo piston bolt should turn freely but should not move in or out of the servo piston.
Assembly Rear Pump Assembly Note "V" notch locations Valve Plate Identification Lefthand Rotation Righthand Rotation Step 7 Step 8 Step 9 Step 10 Fit an O-Ring (p/n 16015-34) in the groove on a servo cap plug 5989898-001. Place the servo cap plug over the servo piston bolt, and turn the servo cap plug until tight. Torque will be adjusted later. Turn the housing so that the bearing bore faces up.
Assembly Rear Pump Assembly Step 15 Step 16 Step 17 Step 18 Lubricate the valve plate and each piston bore in the cylinder barrel with clean hydraulic fluid. Center the cylinder barrel on the valve plate with the brass shoes facing up; apply clean hydraulic fluid to the brass shoes. Set the gasket 5984712-001 on the roll pins. Insert the rear pump shaft through the rotating kit until it engages the spline.
Assembly Rear Pump Assembly Step 27 Step 28 Step 29 Step 30 Turn the rear flange over and place it on the housing. Lower the flange in place so that the bolt holes are aligned. Insert a 16mm x 45mm sockethead cap screw 114978-045 in each of the four bolt holes; tighten them to 145±10 n/m (107±7 lb-ft). Turn the assembled housing and flange so that the rear pump shaft is horizontal.
Assembly Front Pump Assembly Note "V" notch locations Valve Plate Identification Lefthand Rotation Righthand Rotation Step 1 Step 2 Step 3 Step 4 Turn the housing so that the bearing bore faces up. Insert a roll pin 16026-610 into the guide hole near the bearing bore; tap it in firmly with a rubber mallet. Insert 52mm tapered roller bearing 5988197-001 in bearing bore, with taper narrowing from top to bottom; bearing cup should rest on snap ring.
Assembly Front Pump Assembly Step 15 Step 16 Step 13 Step 14 Level the swash plate by hand, and use a locking C-clamp on the swash arm to keep the assembly from moving. Apply petroleum jelly to the inner faces of the cradle bearings (p/n 5991097-001). Step 17 Step 18 Step 19 Step 20 Apply petroleum jelly to the outside of the cup side of the taper bearing and place it in the bearing bore of the front flange. Remove the locking C-clamp, taking care not to tip the swash plate assembly.
Assembly Front Pump Assembly Step 25 Step 26 Step 27 Step 28 Subtract 0.05mm from the recorded measurement; this will be the thickness of the required shim stack. Loosen the cap screws114978045 from the front flange, then remove the flange from the housing and set it aside. Hold the swash arm in place with a locking C- clamp. Combine shims to reach the required thickness. Remove the taper bearing cup from the flange, and place the shims in the bearing bore.
Assembly Front Pump Assembly Step 37 Step 38 Step 39 Step 40 Insert a high-pressure relief valve in the first pressure relief port. Tighten to 143 n/m (105.5 lb-ft). Repeat process for other three pressure relief valves and ports. Assemble a speed sensor: Slide an O-Ring 4995422-001 on the straight end of the sensor (Refer to Item 55, page 5 for part number), place a washer 16048-077 and snap ring 16120-125 on the plug end of the sensor. Insert the sensor sub-assembly in the speed sensor port.

Start-Up Procedure When initially starting a new or a rebuilt transmission system, it is extremely important that the start-up procedure be followed. It prevents the chance of damaging the unit which might occur if the system was not properly purged of air before start-up. 44 1. After the transmission components have been properly installed, fill the servo pump housing at least half full with filtered system oil. Connect all hydraulic lines and check to be sure they are tight. 2.
