forge actuator bodge

[jamie16v]

i recently bought an unused forge actuator off ebay, i bought it cheap, simply because the seller didnt advertise it well. The thing is it was for a diesel. beh, easy i thought, i will use the bracket from my old oem actuator and just extend the rod, piss easy...
when i took the actuator apart i soon realised... sh!t, this thing works on negative pressure.. how can i fix this?..
i thought, right, easy, i will just swap the spring to the other side of the piston... good idea, but the slot the other side of the piston was marginally too small for the spring.. luckily i had a plan.. i know someone with a lathe  .... one day later and the piston is returned with the piston machined and the sping fits perfect. i put the actuator back together and it now works on positive pressue  .. a brand new forge actuator for £60.
it goes to show, you dont have to buy stuff off the shelf if you are prepared to have a go at making things work..

Scrapheap challenge awaits you Handy Andy...

negative pressure? You mean vacuum

I think I would have resold it tbh

Who is this guy

Good effort mate. I don't even kno what your on about positive and negative pressure. The diesel turbos work on negative pressure? Please explain

same thing!

thought about it, but felt like a challenge...lol

I didn't think diesels ran vacuum?

top bannanna  well done jamie

god knows mate, but the spring on this thing was on the piston crown.. so needed vacuum to work against the spring
