I can't wait to see / hear how you get the stock dowels out , not sure if using a penetrating spray will help or make it too slick to clamp on with vise grips ? … Good luck !

Heat it up a bit.

There’s no room to use penetrating oil. Those things are pressed in there really good. I guess it won’t hurt to try it.
I tried heating One up and that didn’t seem to work. I ended up having to Drill that one out with a drill.

The one that came out “easier” I grabbed with vise grips and just spun it from side to side. stopping every once in a while to get a better bite on the dowel With the vise grips.

Just be patient and you’ll get it. It took me 2 days to get them out, when I would start to get really frustrated and angry I would walk away from the job for a while.

one other tip, I trimmed the heating blanket along the seam where the snout mounts to the blower and I made sure to leave the bots exposed. this way If I decide to do a pulley swap down the road I can separate the snout from the blower without having to remove the heating blanket. Hopefully the pictures will show what I mean.

I thought about that too ? .. on s/c , not dowel.

I wonder if it would be as good to just put shorter dowels in the head & not take out the ones in the s/c ?
where the 2 sides would split the difference within the spacer.

 

[Hickster]

Either a heat gun and easy out. You really don't want to tap em out. Much damage. Pipe fitters 26 20 years. Had some old bad situations.

That shows some great ingenuity on your part but in my opinion that won’t be good enough.

Here’s why. the holes on the spacers where the dowels go are machined too big. Theres too much play because of this Therefore the dowels won’t be as precise and you’ll still have side to side play between the motor and the blower.

 

[Alain]

I don’t know what an easy out is.

Trust me, I don’t recommend drilling them out like I did. I was shitting my pants When I did it because I didn’t want to Change any of the tolerances machined from the factory. I had no choice, the dowel was so chewed up that I couldn’t grab it with the vice grips anymore.

just take your time, check and re check what you are doing.
I don’t think a Heat gun Will get the job done. I used one of those hand held propane torches from Home Depot

Dont heat up the dowels, it’ll make them soft and as soon as you put the vice grips on them they’ll turn to mush.

Yeah your right , & I like what you did with the blanket , I did my spacers & blanket b4 I did my pulley , about a year later & I had to cut at the seem & push back the edges around the bolts. I wish would have just done it all at once but I wasn't ready yet LOL.

 

[Hickster]

That's why you use a hair dryer or heat gun,, if you live up north, not a torch from home depot. Way too hot. Like the man said take your time,, throw a bud light in there every 39 minutes. 39 is as long as it is going to take to get one out. Wish I was there to help. Pulling old pipes and mechanical parts apart for years. I will be interested in how you do it cause i will be just as frustated myself. I do have my own blanket which I used in the same manner.

 

[vortecd]

We will see. If it looks to be tootough then they might just stay in

 

[Hickster]

Why knot.

Also @16GoManGoHC2 noted on other posts to make sure you don't cover two relief ports with the blanket or the oil pressure build up won't be able to breathe and you will have problems. He will probably chime in if he sees this.

Never heard of this. I don’t remember seeing any ports on the bottom of the supercharger.

These, they are breathers connected to gear case and are right behind the seals on the firewall side of the rotors.

So are these breathers on the bottom or on the end side at firewall ?...I don't remember seeing these but I wasn't looking for them either.

 

[vortecd]

You can see them uncovered in this pic also. Sounds like they need to put some instruction of do and don't with them

I felt good about how I did the FI spacers till I started seeing this thread , now I feel like I need to start over.
FI didn't say any thing about these vents & to not cover them & they said the dowels were no issue that the bolts would hold just fine. Now I don't know who to believe or if I need to redo ?
