New Forge Actuator

[oceanic-green]

Book a room at the premier inn? If you discuss it with r-tech they could probably sort somethin with you and get two days booked in back to hack but I know they ate quite busy lately.

Yeh, it is a good idea, but due to being a single parent of a 10 yr old boy it is a little hard to disappear for a few days while he is at school. I may have to wait until he has half term and take him with me, if they can book me in for then!

But I did notice yesterday that the  bit that the rod on the actuator is connected too (is it the waste gate ?) does move a slight bit. Should it do so?

No it shouldnt move at all unless you put pressure on it.
If you grap the actuator rod and apply pressure towards the turbo intake pipe your opening the waste gate. If you can move the rod with little effort you need to apply pre-load on the actuator.

Its easy to do this, undo the actuator so the waste gate can open/close easy.
Re-install the rod through the wastegate until its in the closed position and lock with the nut, turn the nut a further 2 full turns (this is the preload)

Once this is done you should not be able to feel any movement unless you put abit of force on it to open the wastegate.

Thanks for the reply jamie1989. Can I do this from above, as I can't get underneath to do it.
Here is a picture I just took of it, with the blue arrow pointing to the bit that I can move when I press it

[jamie1989]

Yeah easily. Thats how I do mine.
Undo that nut on the end until you can feel the wastegate is loose.
Close the wastegate as far it will go, do the nut up then once the wastegate is closed do a further 2 FULL turns.
Job done in less than 2mins.

Cool.
To close the waste gate is that pushing it towards the actuator, the way my arrow is pointing?
I thought pre load should be 3 full turns, not two 

Cheers

[jamie1989]

Yepp thats right.
Once its loose youl feel it and youl know when its open or closed.
The actuator is their to keep it close and if you havent got enough preload on it as soon as you boost your potentially opening the wastegate early.
I did just over two full turns on mine to be certain it was enough, Mine was absolutley fine when being mapped and holds boost perfect.

Ok, that was easy enough  Here is the picture of it now, and the bolt is further done up the rod.


Thanks for your help 

[jamie1989]

That looks better, give it a blast 

[oceanic-green]

right, took it for a spin, and it is definitely better. The liquid cube gauge measured up to 176 bhp, but I couldn't really test it out properly due to the amount of traffic about. Plus I think some of the T pieces on the silicone hoses need replacing, because one of the hoses was far to easy to pull off, even with a hose clamp on  I think it was because of the T piece was from halfords and has only one barb on it. So I could be loosing a bit of boost from there as well
