Supra JZA80 How to Overhaul the Power Steering Pump

It is an overhaul of the power steering pump (vane pump). First, remove the battery, piping near the throttle, auto tensioner damper, and belt. The pump is fixed with three bolts marked with orange circles. In addition, remove the hose that connects to the power steering fluid reserve and the hose that connects to the rack. Those who connect to the rack were removed with 22 mm and 24 mm spanners. It’s hard to see in the picture, but the pump is further fixed to the base bracket with two 14mm bolts. I used an impact wrench to remove the pulley. It’s 17mm. If you think it’s power steering fluid, but it’s bearing grease. It’s popping out. ① Remove the pulley and remove the bolt that connects to the 24mm rack and the bolt that connects to the 12mm reserve.② Remove four 12 mm on the back side.③ Introducing the vane pump. From the right, the back cover, wave washer, vane pump lid, body.④ Gently remove the vane pump so that it does not fall apart. I didn’t move it until I put it on an acrylic board and assembled it. This is a replacement part.Above is the vane pump […]

Supra JZA80 How to Grease Up the Clutch Release Fork

When you operate the clutch slowly, you will hear a strange noise from the bottom of the car body, so grease it up to the release fork. First, jack up the car so that you can access the area around the clutch release cylinder at the bottom of the passenger seat side. Next, remove the clutch housing cover attached to the side of the clutch part of the mission and open the service hole of the clutch housing. Two red circle bolts. Remove the clutch release cylinder fixed to the side of the mission to free the clutch release cylinder. Two bolts indicated by red circles. Slide the clutch release cylinder in the direction of the arrow to release the tension on the clutch release fork. Care must be taken not to overload the pipe connected to the release cylinder. Pull out the clutch release fork toward you to remove it. Since the release fork is fixed with a hook-like part and a spring, it can be pulled out from the service hole by pulling it toward you when the release cylinder is not under tension. Apply clutch release hub grease (genuine Toyota) to the red circle part of the […]

Supra JZA80 How To Change Transmission Oil

Preparing for work Here’s a summary of what you need to change Supra’s mission oil. Mission oil 2L 17mm socket or combination wrench (It requires a lot of torque, so it should be as long as possible) Spinner handle, ratchet wrench, etc Stainless steel pipe with an inner diameter of around 10 mm (Use with a combination wrench) Liquid gasket Oil suction equipment such as suction gun Creeper (Convenient if you have) Waste oil processing box Paper waste Disposable vinyl gloves Work gloves Brake cleaner Hydraulic jack and rigid rack Lowdown slope How to change the transmission oil The yellow circle on the right side of the photo is the oil inlet, and the yellow circle on the bottom is the oil drain. Since the standard amount of mission oil for Supra is 1.8L, you can work by preparing 2L of mission oil. At least the front must be jacked up when changing. After jacking up, be sure to use a rigid rack as a safety measure. (The 5MT W58 mission uses 2.6L of oil, and the 6MT V160 or V161 mission uses 1.8L of oil.) Now, I will explain the flow of mission oil change. First, run your Supra […]

Supra JZA80 How to Replace Starter Motor

First, jack up and fix it on the stand. At the same time, it is easier to work if you remove the front left wheel. It is even better to remove the front bumper if possible. If you have a lift, you don’t have to this. Remove the Supra starter motor from below. All you have to do is remove the two bolts that secure the starter motor. However, it is very narrow and difficult to work with. This may be true not only for 2JZ but also for 1JZ. By the way, the bolt diameter is 14mm. Remove it by making full use of the 14 mm socket and the long extension and universal joint. If you loosen it with a torque wrench first, you can remove it easily. Be careful not to drop the bolts as they are long! It is safer to wear protective equipment. If it comes off so far, remove it while being careful not to drop it.

Supra JZA80 How To Improve Keyless Entry System Reception Sensitivity

The time when Toyota Supra JZA80 made its debut was just the time to shift from the infrared type keyless entry system to the radio type. The infrared type directs the infrared wave by directing the key to the door key cylinder. Sensitivity is poor and will not respond unless it is very close. A typical example is Subaru Legacy BG5 and so on. Toyota cars around 1992 have mostly adopted the radio wave type. The keyless receiver, which is a dealer-installed option, is equipped as such a box under the driver’s seat. Open the tabs of the receiver little by little using a flat head screwdriver. Lift the other side of the connector and remove the black case cover, avoiding the blue connector. The circuit board comes out. While you’re at it, it might be good to check for electrolyte leaks. The operation time is short, so I think it’s OK. Below the big coil, there is a part where “ANT” is printed on the circuit board. Solder appropriate wiring here. The length should be about 1 to 1.5 meters. Even if you turn this variable resistor, it will change, but it will change just a little, so you […]
