Default Re: Removing Plenum Pressed Fit Fittings the Easy Way

Jerry,

No idea where my slide hammer is but I found the little adaptors to grab the press fittings with.

I started with a length of 5/8 UNC threaded rod.

1. Drill a hole up the end of the threaded rod the same as the OD of the non-flared bit of the fitting you are removing.

2. Using a 1mm cutoff wheel on the grinder - slot the end of the threaded rod down the centre about 5 or 6 threads.

3. Cut off this slotted end of the threaded rod to get the 2 little half moon pieces as shown in the pics.

4. Place either side of the fitting you are removing, lining up the thread on the 2 halves and wind a nut on. (A couple of turns is all you can go as you need the other half of the nut to connect to the slide hammer.)

5. Screw a piece of threaded rod into the other side of the nut and nip up finger tight.

6. Attach slide hammer to other end of threaded rod and they will pop out with very little effort - from memory, I actually removed the slide bit off my slide hammer and put it on the threaded rod and put another large washer and nut on the other end to hit against.

7. You will notice I have ground 1 nut down smooth so it is cylindrical - this was needed to squeeze between the runners and back of the flange where the throttle body goes as I couldn't turn the hex nut on a couple of them.

I think there is 3 sizes you would need to make for all fittings. I didn't have to remove the tiny one on the throttle body as Greg Van Deventer removed it when he did the 63mm throttle body mod.

If I was making a set to use all the time, I would probably also just countersink the hole in the end of the threaded rod a little bit with a larger drill before cutting and slotting as it would fit up against the flared bit nicely. My ones hardly marked them anyway though.

If you were worried about crushing them, you could poke a tight fitting bit of rod up the guts of the fitting first. The little adaptors I made do not try to crush the fittings though.

Hope that helps.
Matt
