| 03.10.2005: Wastegate actuator |
|
The actuator consists of a vacuum box and a rod that pulls the wastegate
arm.
|
 |
| 03.10.2005: Vacuum box |
|
The spring is inside the vacuum box. The box is a round can with a rolled
rim.
|
 |
| 03.10.2005: Opening the can |
|
Use your favourite tool to pry off the edge of the rim. Be careful not
to bend it too much as the rim has to be rolled back in later.
|
 |
| 03.10.2005: Almost there |
|
Continue around the entire perimeter. Medium sized vice-grips work well.
|
 |
| 03.10.2005: Pop |
|
Sooner or later, the can pops open. The spring is not that strong, so don't
worry about it shooting away and crashing your china.
|
 |
| 03.10.2005: Apart |
|
The wastegate actuator apart. You can see the can, the spring, the
rod with a piston attached, and the rubber membrane.
|
 |
| 04.10.2005: Wire brush |
|
This might be a good time to clean the rust and dirt accumulated on the can.
|
 |
| 04.10.2005: Membrane |
|
Clean the membrane, inspect it for cracks and lubricate with your favourite
rubber treatment for longevity.
|
 |
| 04.10.2005: Springs |
|
The spring supplied by Nordic is noticeably beefier.
|
 |
| 04.10.2005: Clamped together |
|
Put the actuator back together and clamp it. Make sure the edges of the
membrane are evently centered around the rim.
|
 |
| 04.10.2005: Rolling back |
|
Roll the rim back in. Be careful not to crack the metal. I don't think
it will withstand one more operation like this.
|
 |
| 04.10.2005: Crimping |
|
Press the edges tightly with vice-grips or another suitable tool. Check
the box for vacuum leaks.
|
 |
| 04.10.2005: Ready to paint |
|
I decided to paint the actuator while I have it off the car. Don't forget
to mask the inlet and the threads.
|
 |
| 04.10.2005: Finished |
|
Primed, painted and ready to go back on the car.
