In a piston valve, the control of stem and seat leakage is obtained by tightness of the valve sealing rings to the body and valve plug. The bonnet compresses the valve sealing rings against the body and the valve plug. Flexible disc springs automatically assure a tight seal by exerting pressure on the valve sealing rings, keeping them compressed. Opening and Closing the TVS Isolation Valves The isolation valve begins to stop flow when the valve plug enters the lower valve sealing ring. When the isolation valve is completely closed, the valve plug is in contact with the full height of the valve sealing rings, ensuring the best possible seal. In fact, there is no advantage to be gained in torqueing the valve closed. Armstrong recommends that after closing the isolation valves completely, the handwheel should be turned back one half turn. This makes it easy to re-open the valve by avoiding metal to metal seizure. Troubleshooting – Isolation Valves A piston valve will retain its leak tightness for several years without maintenance. In severe service, such as rapid heating and cooling, some field maintenance may be required. Depending on the problem, these simple steps may help: ! ! ! ! ! Isolation Valve leaks, when the valve is closed . First, Check to make sure the valve is actually closed . Check to see if bonnet is seated on the body, if not, tighten the bonnet nuts until the bonnet seats. This recompresses the valve sealing rings against the body and the valve plug. If valve continues to leak, replace the isolation valve assembly

Removal of the Brake-side Bearing Cup The bearing cup (5) is located endwise by a circlip (1), and between the cup and circlip arc an oil-seal retaining washer (4), oil seal (3), and oil-seal cup washer (2) Before these parts can be removed from the hub the bearing cup must be moved inwards for a very short distance (3/16-inch) so that the circlip can be withdrawn. (n) Gently heat the hub shell. (i) Place a soft metal rod (e.g. brass) against the oil-seal cup washer (2) and apply pressure with a hand press or hammer blows. It is only necessary to move the bearing cup (5) inwards about 1/16-inch. (j) Extract the circlip by inserting a narrow pen-knife blade under one end of the circlip; lift it upwards and outwards and prise the clip out of its groove. (k) Remove the oil-seal cup washer (2), oil seal (3) and oil-seal retaining washer (4). They can be hooked out with the shank of a small and narrow screw­ driver, (l) The bearing cup can now be ejected by placing a suitable rod of soft metal (e.g. brass) in the hub tunnel from the right-hand side and pressing it — with a press or hammer blows — against the bearing cup until the cup is forced out of the bearing. This must be done with care so that the cup remains square with the housing. Reassembly To facilitate replacement of the bearing cups gently heat the hub shell. Just too hot to hold is about the right temperature. (a) Place the brake-side bearing cup squarely in the hub shell — the open end faces inwards — and press it into the hub tunnel A short length of brass rod, slightly less than the outside dia­ meter of the cup, should be interposed between the cup and ram of the press, or hammer head. Press the cup in until the outer face is approximately half-an-inch below the mouth of the hub tunnel. This will allow sufficient room to allow [he circlip to be inserted into its groove. (b) Refit in the following order: oil-seal retaining washer (4), oil seal (3), oil-seal cup washer (2). (c) The circlip can now be replaced. In the interest of reliability use a new circlip, for it is possible that the existing circlip was strained when it was re­ moved. (d) Insert into the hub tunnel from the right-hand side a brass rod of suitable length, and press the bearing cup firmly against the circlip. (e) Before inserting the spindle complete with the roller races, pack them with clean and fresh grease of a suitable grade (Mobilgrease No. 4. Castrolease heavy, Energrease C3, Esso Pressure Gun Grease. Shelf Retinax Grease CD or A). (0 Insert the spindle into the hub. (g) Place the right-hand side bearing cup in the hub tunnel; the open end faces inwards, It may be necessary to re-heat the hub to allow the cup to go into position without difficulty. (h) Press the cup into position, but do not force it fully home, leave some end play on the spindle. (i) Refit in the following order: oil-seal retaining washer (6), oil-seal (7) and oil-seal cup washer (8). (j) Screw into the hub the adjusting sleeve (9) until it comes into contact with the bearing cup (5)

FUEL PUMP The electric fuel pump is mounted at the bottom of the fuel tank, which consists of the armature, magnet, impeller, brush, check valve and relief valve . The ECM controls its ON/OFF operation as controlled under the FUEL PUMP CONTROL SYSTEM . When electrical energy is supplied to the fuel pump, the motor in the pump runs and together with the impel- ler . This causes a pressure difference to occur on both sides of the impeller as there are many grooves around it . Then the fuel is drawn through the inlet port, and with its pressure increased, it is discharged through the outlet port . The fuel pump has a check valve to keep some pressure in the fuel feed hose even when the fuel pump is stopped . Also, the relief valve is equipped in the fuel pump, which releases pressurized fuel to the fuel tank when the outlet of the fuel pressure has increased up to 450 -600 kPa (4.5- 6.0 kgf/cm2,64- 85 psi) . Relief valve Brush , ∎ I,’ Check valve Magnet L Armature When the impeller is driven by the motor, pressure differential occurs between the front part and the rear part of the blade groove as viewed in angular direction due to fluid friction . This process continuously takes place causing fuel pressure to be built up . The pressurized fuel is then let out from the pump chamber and discharged through the motor section and the check valve . FUEL SYSTEM AND THROTTLE BODY 5- 3 Inlet port I I Impeller 5-4 FUEL SYSTEM AND THROTTLE BODY FUEL PRESSURE REGULATOR The fuel pressure regulator consists of the spring and valve . It keeps absolute fuel pressure of 300 kPa (3.0 kgf/cm2,43 psi) to be applied to the injector at all times . When the fuel pressure rises more than 300 kPa (3 .0 kgf/cm2, 43 psi), the fuel pushes the valve in the regulator open and excess fuel returns to the fuel tank . 90 Spring 02 Valve FUEL INJECTOR The fuel injector consists of the solenoid coil, plunger, needle valve and filter . It is an electromagnetic type injection nozzle which injects fuel in the throttle body according to the signal from the ECM. When the solenoid coil of the injector is energized by the ECM, it becomes an electromagnet and attracts the plunger. At the same time, the needle valve incorporated with the plunger opens and the injector which is under the fuel pressure injects fuel in conic dispersion . As the lift stroke of the needle valve of the injector is set constant, the volume of the fuel injected at one time is determined by the length of time during which the solenoid coil is energized (injection time)

Assemble triple lip output seal 705002 and output spacer 280001 together. The seal is shipped with high performance grease packed into the seal lips to ensure lubrication and exclude dust & water. (Caution: Only high temperature grease should be used, grease is better than oil, never install the seal dry.) Slide the quad ring and seal/spacer assembly onto the transmission output shaft, then slide tool JE300001 ( TwistGear TM ) or JE300002 ( WideGear ) onto the shaft and finally tighten the nut until the tool drives the seal flush with the case. Do not attempt to install the main drive seal without the JE tool or the seal will be damaged, and the seal performance will be compromised (the JE seal is wider around the shaft for the third sealing lip, which will be damaged if a tool is pressed against it.) It is best that a new JE spacer be used each time a new seal is installed for quick break-in of the main lip seal surface. Counter Shaft Assembly Note the order and orientation of the gears on the counter shaft when it is removed from the trapdoor. Disassemble the counter shaft and transfer the parts to the TwistGear TM counter shaft. Note that the TwistGear TM counter shaft assembles in different order than the OEM counter shaft. Two washers are required in the position as shown in figure 1 (see arrow) before the retainer ring is installed. The second washer is included in the kit.

Remove the stock transfer case from the stock tailhousing adapter. The stock tailhousing is retained along with the stock rubber crossmember support. Once the transfer case is removed, you’ll see a seal located in the stock tailhousing. This seal must be removed and discarded. Some tailhousings also had a bearing which also must be removed. Install the new oil seal into the large end of the seal adapter. The sealing lip should be facing down. The small end of the seal adapter has the same O.D. (outside diameter) as the old seal that was just removed from the stock tailhousing. The seal adapter is a press-fit into the stock tail and should now be installed. The kit comes with a new spud shaft which fits over the stock Toyota transmission 26 spline output shaft. This spud shaft has a Jeep 23 male spline on the opposite side which fits into a standard 23 spline Atlas case. When installing the spud shaft into the Toyota transmission, the spud shaft does not seal onto the new seal just previously installed. The seal contacts seal off of the Atlas input shaft. The adapter plate should now be installed onto the Atlas transfer case. The adapter plate indexes off of the Atlas front retainer

Remove the valve from the shipping package (box or pallet) with care taken to avoid any damage to the valve and actuator (plus accessories where applicable). •Before installation, remove the seal discs from the flange. Clean the inside of the valve using an air line that includes an appropriate air-filter. Ensure that there are no solid objects such as pieces of wood, plastic or packing materials within the valve or on the valve seat. •Confirm that the materials of construction listed on the valve nameplates are appropriate for the service intended for and are as specified. When in doubt contact KTM, or your local Tyco facility. •Define the preferred mounting orientation with respect to the system pressure. The arrow on the body helps to identify the upstream side (high pressure) and downstream side (low pressure). •Ensure that all stud bolts and nuts of the body joint are firmly fastened. Caution •Verify that the direction of the flow in the line corresponds to the arrow indicated on the valve body. Valves without the arrow are bi-directional. •See the Actuator User Manual for the actuator preparation. 2.2. Installation Instructions •Ball valves are normally installed in horizontal pipes with the stem facing up. However, there are no limitations regarding the pipe or stem orientation. •Unless otherwise recommended by KTM, the valve should be installed with the ball in the open position, to ensure that the seat rings are not damaged during installation. •Particular care should be taken for valves equipped with “fail-close” actuators. •For operating temperatures above 200°C (392°F), thermal insulation of the valve body is recommended to protect the actuator/accessories from heat beyond the recommended temperature range. •Handling and lifting of the valves during installation MUST be performed following the same criteria and instructions described in points 1.2. and 1.3
