2G Fluidampr pulley bolts

[MasterMatt209]

I’ve got a new fluidampr pulley arriving today and I just wanted to know what I should do for bolts? I had someone on another post of mine say hardware store bolts would do, is that true?

I ran 10.9 bolts there for years without a problem.

I went and got some grade 8s from Fastenal with lock washers, been perfect since install and I've had to remove it a couple times. I used blue loctite on mine for insurance.i can't recall the length I got, I want to say 15mm?

That’s perfect thank you both for the fast response. My local hardware store carries grade 8 so I’ll be sure to get them so at least I have some high quality bolts. Anything I should know going into this? I know I may possibly have to lower the engine slightly if I don’t have clearance to get a bolt.

There's a thread out there documenting how you need longer bolts with the Fluidampr.

If it's a new unit, the thickness has been addressed. The last two new units I purchased, the OE hardware was plenty long enough.

If used, I would measure the thickness of the base to see which version you have (10mm or 17mm).

I’ll check that and get back, I bought this brand new in box off of someone so I couldn’t say I know which one I have. But I will check

10mm does that’s mean I can use stock size bolts?

Correct

 

[MasterMatt209]

Correct

Sweet I already got the old pulley off I’m heading to the hardware store now for some new bolts.

 

[MasterMatt209]

Anyone know how long they should be though? I think the ones I have are 25mm.

I looked it up oem spec is 25mm long

She’s in boys! Bolts are torqued to spec with lock washers, the bolts are grade 10.
