AFC Housing Bolts
 

I went to move my afc housing forward today and I got to loosening the bolts and found that the fourth one (forwardest closest to the engine) wasnt even a bolt, it looks like a tiny allen head but way to small to do anything with how do you get this off its not a bolt head or a philips its just a round head. I was able to move the housing just by tapping it forward with a hammer but Im going to want to take off the housing to change the fuel plate.

it's a tamper proof screw. you can take an impact driver with a torx bit in it and hammer the torx head into the top of that bolt. the impact driver should losen the bolt once you start hitting it. i took a chizzle to mine and beat the head off it. removed what was left of the bolt and then went to Fastenal and got allen headded bolts to go back in there on all 4 corners......

So Ive gotta hack it outa there then replace it with a bolt correct? Im guessing since this bolt is still in there the stock plate is probably still in there right?

maybe..... tst supplies a new tamper proof bolt with their plates..... is the bolt the color of the housing or a goldish silver color?

i used a coal chisle and taped on the side of it till it would unscrew easy..

or just take a dremmel and carve a slot for a screw driver..

Its the same color, looks like the housing was still in the stock location as well. Im thinking the only thing the previous owner messed with was the star wheel. does the afc have to be removed to install a GSK?

I think thats what Im going to do.

it should have the stock plate in it. and no you don't have to remove it to install the GSK....

Ok thanks for the help fellas, Should I see a big improvement if I cut the plate to say a 100?

YUP!!! just make sure your pyro works..... my egt's didn't increase much with the 100 till i installed the GSK..... man the difference those springs make..... well worth the money.....

Air Chisle is my favorite way!

um.... i dono what to say..... that space is too tight between the AFC housing and the injector lines for me to attempt that..... a couple of wacks with the hammer and cold chissle should get her done..... the bolt head is perty soft....

Ya I think my egts will be ok I made 1200* the other day on a really steap hill in third WOT.

Hehehe , You gotta think, We use a 18 inch long chisle and one bump (Not to turn or cut the bolt) It'll twist out with your fingers! Sorry if that was confusing!

wow I used a hacksaw blade on my friends its all I had around then an impact screwdriver. for mine I went the dremel route cuz the whole pump was out of the truck.

i went the dremel route it worked great

I guess I am the odd man out, I used a cutting torch to blow the head off the bolt

talk about overkill.... you and Mystery need to get a shop together....

geez a blow torch! that can't be good for the rubber seals
not to mention all the fuel lines right there

:lol: I've got 3 ASE Techs, I think i've got mine together! I Explained why i did what i did!! :) You should see how these guys take off fan clutches in the dealerships :lol:

if it is anything like how I do it I'll lol the last one I ended up welding the wrench to the nut because it was rounded off.... the look on the guys at sears when I took the wrench with the fan still on it in there to swap it was priceless

Next time try the longest chisel bit on your air hammer, It'll come right loose :)
It's gotta be pretty long! Mac is the only vendor that I've seen with one!
