Default Turbosmart Boost Tee Repair

Well it seems that my boost tee has taken a ****. I am having issues holding boost or over boosting. When I am at full throttle the waste gate sounds like its flapping in and out really fast. I disconnected the MBC and the waste gate boosted to 9 psi just fine no issues holding boost. I received the MBC with a kit I bought second hand and I was just curious if there is any instructions or repair kits. I have ordered a DIY EBC cause the over boosting scared the **** out of me and I dont want that to ever happen again but I still would like to get the MBC repair so I can use it for the time being or sell to someone else.

I saw a guide the other day online. The boost source input unscrews and the ball and spring come out. There is a guide from turbosmart on cleaning it, just google it. These things are pretty simple to work with. Here you go, was still up on my other computer:

Quote:
Perform this modification on a clean bench so that the ball and spring are not lost
• Allow the engine to cool down before removing the Boost Tee from your vehicle
• Identify the input nipple with the restrictor at the end. Loosen the input nipple and remove the ball and spring.
• Check that the internal air passages are clear and free from debris
• Re-install the boost controller by following the instructions for your setup
• You will need to re-adjust your boost settings after the removal of the gate.

TROUBLE SHOOTING

The following points should be checked if you find that your engine is developing excessive boost, the boost pressure is fluctuating or
the desired boost level cannot be achieved. Please note, the following checks will cure 99% of problems experienced when fitting a
Turbosmart boost controller.
• Check that the boost controller is installed so that the arrow points toward the wastegate actuator
• Check the joining hoses for splits, cracks or loose connection and are the correct size for the application
• Check to see if the boost controller is blocked or contaminated with dirt or debris
• Ensure that there is nothing but the boost controller in the hose between the pressure source and the wastegate actuator, ie tee
pieces for boost gauge or to factory boost solenoid.
• Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split
• Check that the wastegate is operating correctly

I understand how to do that and I did clean it. I just need to figure out how to detach and replace other parts. Here is a pic of what I mean as far as taking it fully apart, but I cant figure out hot to get the adjustment **** off or the parts to replace it.

I didnt ever purchase the solenoid till today. The PO of the kit was running a MBC even though the MS2 DIY N76 has it already wired it just needs the solenoid. I used the MBC as a temp till I got around to figuring out how to tune EBC in TS. I dont want to jump the gun but IMO it doesnt look that difficult
