Hi

The ABS pump is supposed to switch off when you turn off the ignition. When it keeps running for too long the motor burns out. You have to check for presence of voltage on the connector to the pump. If it is present and the pump doesn't work your pump is gone. You need a new pump or overhaul the electromotor by fitting a new rotor. Check your black ABS pump relay and change it as it might be faulty and the cause of your troubles in the first place.

Regards

Hi

You can remove the pump first with unscrewing the 3 screws that hold it to the motor.

The remove the plastic shield at the back of the motor.
Now unsolder the electric wires.
Open the back plate by carefully tapping back the steel ridges that hold the plate in place.
Lift off the plate and remove the paper and rubber insulation of the wires.
Now you can take out the carbon brush assembly followed by the rotor.

If your carbon brush holders are in good condition you might be able to fit a new rotor.
If your carbon brush holders are completely melted you have to find new ones. I have no idea where. I used two burned out motors to make one working one.

I sourced one from:

http://www.invasionautoproducts.com/abs ... r8802.html

They list that they are out off stock but if you call them and send in your old one they might be able to repair it.

There are some photo's of the repair at the following link:

http://www.jpurnell.com/RR/repairs/abs_pump.htm

The link is for the classic pump but the P38 pump is similar but has 3 plungers instead of 5 like the classic.

If you can find a classic pump then you can use the classic motor to fit on the P38 pump, and use the rubber shocks at the back of the motor instead of the screw down bracket from the p38.

Good luck

Jos
