View Full Version : Disable ACS bolt...fact or fiction???

04-30-2007, 08:26 AM
So I spent HOURS looking thru the forums last night, and never really made heads or tails over whether it was actually possible to disable the Anti-Chop bolt, as I have heard, on the MR2 by loosening the set screw, and turning the enternals (or something to that effect). I did find one thread which hinted at the fact that it was tried...but found to be un-true. Can anyone shed some light on this tale? AND...if it is so...does it apply to the earlier first run MR2's?

I can tell you for a fact, at least on mine, the ACS bolt can be disabled, and it is the set screw that does it. I got my MR2 used and the previous owner had disabled the ACS. I've got a picture of the bolt that, I think, shows the set screw in my sale thread, LMK if you need more pics.

I know of the set screw....so a verbal break down on the proceedure would be great. I was looking at the bolt yesterday, and just didnt see how it was possible.

Only thing you should need to do would be to get a longer set screw at Lowes or Ace Hardware or somewhere. Remove original set screw, replace with new longer one.

...you mean longer, so that it makes contact with the hole that the set screw sits in (or access hole) thru the plastic?

what i would do is take apart the acs bolt, take out the spring, and replace it with a small pvc pipe. i was going to do that with mine, but i can't take it apart.

What do you mean first run? Did they make a different revision of the MR2 or something, slightly different?

I wasnt entirely sure of that question either on the first run issue. I think only the detents have changed

Yea....I like the PVC idea alot better. It seems like the set screw constantly hitting the delrin in a place it was not originally supposed to would eventually eat the bolt to pieces. At any rate, thanks to everyone who responded
