HYDRAULIC PUMP FOR CONVERTIBLE TOP


I have a 1987 Toyota Celica GT convertible. I have been constantly refilling the reservoir for the hydraulic pump. There has been a small puddle on the ground everytime I parked the vehicle after cycling the top. I finally removed the pump from the vehicle and disassembled it to find the internal seal (maybe called a lip seal) which allows the motor shaft to enter the hydraulic side to drive the pump gearing to be cracked and damaged allowing the fluid to seep past the shaft into and out of the motor side.
So basically my question is where can I get the internal seals to make this pump leak proof and fully useful again. Toyota has no internal parts for this and it is a discontinued pump. or is there another vehicle which i can salvage the pump from or an aftermarket cheap pump available?
thank you , tony

Top worked fine yesterday but today tried to let down only clicked


It is a hydraulic pump that applies pressure to the 2 hydraulic pistons to raise & lower the top. So, check for something obstructing movement first.

The convertible top:
  • is motor-driven.
  • requires parking brake engaged to complete circuit for operation.
  • is equipped with a back window glass (42006) . The back window glass is permanently attached to the folding top back window curtain (52500) and cannot be opened.

1996 audi cabriolet 2.8 V6 convertible top motor needs fluid how do i add the fluid to the convertible top motor?! and what type of fluid does it need?


Almost all power convertible tops are electric over hydraulic. The ecectric motor runs a hydraulic pump. The pump pushes fluid to the cylinders that work the top. Most are located behind the rear seat backrest. Either remove the rear backrest or access the motor/pump from the trunl. It will be shaped like a cylinder. At one is the electric motor, at the other end is the hydraulic reservoir. At the end of the reservoir is a rubber plug. With the top down, remove the plug and fill it with tran fluid till it over flows. replace the plug and cycle the top up and down as far as it will go. Repeat the process till it will take no more fluid. A turkey baster with a piece of vacuum line makes a good filler tool. With that said, you must find the leak. You may have a leaking pump, hydraulic line or cylinder. RNever replace one line. Do them all. Always replace cylinders in pairs.

My roof is not working and keeps making the worst sounds and the symbol for the convertible keeps blinking. I live outside of the US. Any suggestions.


The most common reason for this is low hydraulic fluid. The noise is probably the pump running while empty. When fluid id present it dampens that noise. Behind the rear seat is the combination motor/pump/reservoir. With the top in the DOWN position, fill the reservoir with ATF and cycle the system a few times as far as it will go. Repeat until the reservoir will take no more fluid. If that works, it is only a patch fix. You must now inspect the lines, motor and cylinders for leaks. The fluid does not evaporate. If it is low, you have a leak. Karl at topgunwon.com

1998 Mercedes Convertible Top Slow and Drips Oil


Your top is moved by an electric motor wich operates a hydraulic pump which moves two pistons which move the top.
The "oil" thet you see is probably hydraulic fluid leaking from the drain hole in the car near the tire.
You have a leak in the hydraulic system.
You need to start at the motor/pump/reservoir unit behind the seat and find the leak.
Most commonly, it is a bad line. Second in popularity is a bad cylinder(s). Third on the list is the motor/pump/reservoir.
If you replace a line, do them all. If you replace a cylinder, replace them both.

1987 Cavalier RS convertible..The pump for the top runs but the top doesnt move. Checked bypass valve to make sure it was closed. Was thinking maybe hydraulic fluid may be low. Car has been sitting for 4...


You are probably low on fluid.
Behind the rear seat is your motor/pump/reservoir combination.
With the top down, fill the reservoir to overflowing with ATF.
Cycle the system a few times and repeat.
Do this till the reservoir will take no more fluid.
Check the lines and cylinders for leaks. The fluid must be going somewhere.
If you replace any lines or cylinders, always do them in pairs.
