  Q: How to service and repair the power steering pump on Toyota MR2 Spyder?

  A: A power steering pump service requires you to start by removing the reservoir cap followed by the reservoir through clamp loosening and removal of the O-ring from the power steering vane pump housing. The process begins by disassembling the rear housing and oil strainer through the step of removing four bolts while also extracting the O-ring from the housing. One must carefully remove the cam ring and vane pump rotor and 10 vane plates while avoiding the vane plates to escape and continuing with the lower side plate removal. Use snap ring pliers to delete the snap ring from the flow control valve before pulling out the spring seat with a service bolt to take out the O-ring, flow control valve and spring. Remove the O-ring from the side plate after tapping it with a plastic-faced hammer together with the wave washer on the upper side plate. Use a micrometer to check the vane pump rotor height and the vane plate thickness and length and make sure they are at minimum 5.4 mm, 0.882 mm and 4.596 mm levels respectively. Then examine the vane pump rotor groove clearance against the vane plate before part replacement following inscribed mark indicators. To inspect the flow control valve you should apply power steering fluid on it and check its smooth movement into the valve hole for any signs of leakage using compressed air and perform a replacement if necessary depending on the inscribed mark. Vernier calipers should be used to measure the free spring length. Replace the spring if its length falls below 28.7mm. A screw extractor removes the union seat which you must apply gentle tapping strokes to install a new fitting. The selected parts must receive power steering fluid coating before installing flow control valve and spring seat with proper positioning while coating the new O-ring. Set the lower side plate properly alongside the cam ring vane pump rotor and 10 vane plates in their respective orientations. The assembly continues with placing the upper side plate after adding an O-ring and then adding the wave washer and an oil strainer and rear housing. The O-ring needs to be properly aligned with the oil hole before securing the 4 bolts at 8.5 Nm torque. The procedure ends with reservoir installation at 7.0 Nm torque level while using a new O-ring and then fitting the reservoir cap.

  Q: How to service and repair a radiator on Toyota MR2 Spyder?

  A: First check the radiator fins for blockage then remove any foreign material from the radiator and condenser as well as clear the hose connection. If the fins are blocked wash them using a water or steam cleaner while avoiding the core area and blow dry them with compressed air. To fix bent fins use a screwdriver or pliers without wetting the electronic parts.
• Wheel Bearing

  Q: How to Service and Repair a Wheel Bearing on Toyota MR2 Spyder?

  A: You must start the wheel bearing maintenance with the removal of axle hub using Special Service Tool: 09520-00031 (09520-00040, 09521-00010, 09521-0020). The axle hub extraction requires all necessary service tools including 09950-00020, 09950-60010 (09951-00380), 09950-70010 (09951-07150) and a press. The dust cover removal process requires taking the 3 bolts out and applying Special Service Tools: 09310-35010, 09527-17011 together with a press to accomplish the bearing extraction. To rebuild the axle carrier install a fresh bearing through the use of Special Service Tool: 09950-60020 (09951-00730), 09950-70010 (09951-07150) together with a press followed by snap ring installation utilizing snap ring pliers. Reinstall the dust cover by tightening its 3 bolts to 8.3 Nm (85 kgf-cm, 74 inch lbs.) before installing the axle hub using Special Service Tool: 09608-32010, 09950-60010 (09951-00550), 09950-70010 (09951-07150) and a press.
• Alternator

  Q: How to service and repair the alternator on Toyota MR2 Spyder?

  A: The generator servicing begins with dismantling it through the process of removing the rear end cover starting with the nut and terminal insulator and moving onward to the bolt and 3 nuts and plate terminal and end cover. The service begins with separating these two components by first stripping off the brush holder cover with its 5 screws and then disconnecting the brush holder and voltage regulator. Afterward detach the seal plate from the rectifier end frame. The first step for the rectifier holder requires removing four screws and then the holder followed by removing four rubber insulators next. The pulley removal process requires Special Service Tool 09820-63010 and a torque wrench for rotating the socket clockwise to 39 Nm (400 kgf.cm, 29 ft.lbf) until the tool fastens to the rotor shaft. Then place the adapter under a vise and attach the socket before adding the pulley nut. To prevent rotor shaft damage twist the tool counterclockwise until you reach around half a turn of the pulley nut. Complete the adapter procedure by extracting the generator followed by removing the socket and pulley holding tool and then uninstalling the pulley nut and pulley. Remove the 4 nuts and wire clip of the rectifier end frame before using Special Service Tool 09286-46011 to detach the frame while also removing the generator washer on the rotor. The reassembly process starts by putting the rotor onto the drive end frame then adding the generator washer to the rotor followed by press-fitting the rectifier end frame using a 29 mm socket wrench while securing it with the wire clip and applying torques to the specified nuts: Nut A at 4.5 Nm (46 kg.cm, 40 in.lb) and Nut B at 5.4 Nm (55 kg.cm, 48 in.lb). The pulley installation requires manual nut securing followed by pulley holding tool application (Special Service Tool 09820-63010) to torque the shaft to 39 Nm (400 kg.cm, 29 ft.lb) and verify pulley shaft attachment. The generator should remain on the adapter after torquing the pulley nut to reach 111 Nm (1,132 kg.cm, 82 ft.lb). The install process of the rectifier holder begins by adding the 4 rubber insulators then confirming the proper direction before applying 4 screws tight at 2.9 Nm (30 kg.cm, 26 in.lb). Place the seal plate on the rectifier end frame then install the voltage regulator after the brush holder while securing all components with 5 screws tightened to 2.0 Nm (20 kg.cm, 18 in.lb). Lastly, cover the brush holder. Install the rear end cover first by tightening the end cover and plate terminal with a bolt and 3 nuts properly torqued at 4.4 Nm (45 kg.cm, 39 in.lb) for the nuts and 3.9 Nm (39 kg.cm, 35 in.lb) for the bolt. After that, install the terminal insulator with its nut at a torque of 4.1 Nm (42 kg.cm, 36 in.lb). Ensure the rotor rotates smoothly. The first step for bearing replacement involves the front bearing where you should remove four screws along with the bearing retainer and bearing before pressing out the bearing using Special Service Tools 09950-60010 (09951-00350) and 09950-70010 (09951-7100). Replace the bearing retainer by installing screws at 3.0 Nm (31 kg.cm, 27 in.lb) torque using tools 0995-60010 (09951-00530) and 0995-70010 (09951-07100). To replace the rear bearing first remove the bearing cover (outside) along with the bearing by using Special Service Tool 09820-00021 while maintaining fan integrity before removing the bearing cover (inside) to set on the rotor. Special Service Tool 09820-00030 enables installation of a new bearing before inserting the bearing cover (outside) using the Special Service Tool 09285-76010.
