Default Flappy Bearing Removal

I once ran across a thread about removing the flappy bearings with a concrete anchor bolt. Can anyone point me to that thread again? I have an 87S4 that I began doing an Intake Refresh on. That has grown into a OPG, oil cooler hoses, tie rod ends, rack bushings and counting.

Yep, that's what I do with all mine. Takes about 30 min. for both. It works, other methods I've tried, including the concrete anchor bolt work about half the time. Also: be careful and take your time. works 100% of the time.

for some reason I also put all the pics in an album here, but didn't seem to link them in the rennlist thread.

Thanks Hilton, that's what I was looking for. I've used the Dremel but can't seem to pry the edge up

It works great on the intake for the flappy.

For the throttle body, the fit is tight enough you just end up cracking off the end of the bearing if you do it cold. However if you heat the throttle body up in the oven, then you can use the same method to pull the butterfly bearings too due to differential expansion of aluminium from the steel bearing case - from memory I heated the throttle body to 200C (around 400F) last time I did this job.

OK, I'm putting a kit together to carry out an intake R&R, and I find this thread. Brilliantly simple idea, which is my level.

Quick question, what size of anchor bolt is the right size. I was looking for 10mm, but they seem to be measured in thread size not O/D size. 10mm give an O/D of 16mm.

6mm thread gives 12mm O/D which is the smallest I've found. I'm in the UK so links to Home Depot won't help.

Happy I found a German supplier of HK1012 2RS bearings

TIA

Kudos for a solidly searchable thread title, too.
