| 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.
