Not sure if I installed this pulley right - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

rhythmM · 12-07-2013, 07:45 PM

As the title says, I just recently bought a new Perrin crank pulley for my car and attempted to install. Installed and reinstalled just because not confident if it was done properly.

The bolt that is holding the pulley in place is kind of going back and forth, the pully itself seems to be spinning fine. And the belt tensioner pulley seems to bounce around too... Can anyone give me some advice on how this looks?

Here is a video of my installed pulley.

That's normal. As long as it's not leaking oil for the inside of the pulley

I tried torquing it again and there still seems to be some slight play with the bolt, the pulley is spinning fine though... I'm just worried about the worst case scenario.

the bolt is loose? I have about 20,000 miles on mine, and it looks exactly like your video.

Replace the bolt. If you do, the worst case scenario is your out $10 or so for nothing. If you don't replace the bolt, the worst case scenario is it breaks, the crank gets unbalanced, you spin a couple bearings and window your block.

Alright, for the sake of my conscience I will probably buy a new bolt and o ring to replace. Hopefully that resolves my dilemma. Thanks you guys.

nope. the same thing happened to me. when you torque it down make sure its parallel to the engine tighning the bolt wont straighten it out. mine did that so i pulled it back off and used a pry bar to keep it parallel and had my buddy torque it. it shouldnt shake like that.

Its fine. I wouldn't worry unless the pulley itself wobbles.

That's normal
