Accufab throttlebody screws

[Nasty Wendy]

What size are the little screws that hold the throttle body blade to the shaft? I know some folks here have replaced/changed them and I'm looking to do the same. Thanks.

Why Would They Replace Them For. Be Careful I've Heard Of These Screws Coming Lose.

Was this a problem with the Kenne Bell TB's as well??

my 70mm is going on 4 years now and no problems. maby i should loc tite them. i didnt know about the cam problem til christmas 2008 and i had a wiped cam 3 years old and didnt even know it.

my buddies 70mm was also about 4 years old and it finally broke. it broke at the head not at the threads. if i owned an accufab tb i would replace them without question right this second.

MARK just the ACCUFAB ones.

Who made them for KB???

Reason I ask is I have a new KB TB and plenum and have done some searching ....... http://www.turbobuick.com/forums/general-turbo-buick-tech/196953-kenne-bell-plenum-tb.html of course you can't believe everything you read on the net. If someone can confirm I will just change out the screws before I install it.

My accufab also snapped at the head about 5 minutes after installing it. Got stuck between the piston and the valve causing major damage. Emailed accufab and they basically told me to go F*** myself. Of course, they had never heard of such a problem. What pissed me off the most was that just replaced blown head gasket and figured may as well install a bigger TB since it will be off. This was about 3 years ago.

Wendy where did you get your replacement screws? Pulled mine off today to replace them. Went to three parts stores. No luck! They are 8-32 thread?

Home depot or lowes has them

Just did this myself and got them from my local hardware store. Ended up going with an allen head type bolt vs the button head design. A little more meat to them on the end. While it projects into the air stream more than the button head type bolts I really don't think it will make any difference. And yes, 8/32's is the size by 3/8" long. Use some red loctite on them and you should be good to go. Do one bolt at a time to keep the TB plate in position.

I had one come out on a 65 mm Accufab. Tore up a head and a piston

Found them. Only they were a little longer than the 3/8. All I could get in this little one horse town. They stick out the shaft about 3/16. Leaving them sticking out going to bother anything? Don't really want to get the dremel around the shaft.
