ETA guys only ;)

So I finally did my clutch I'n my 1987 eta. I decided to go with a 325i flywheel and stage one clutchmasters clutch kit.

So how did I put a 325i flywheel I'n my eta. Easy I just welded the reforence pin on to the i flywheel. Didn't take long to find the right spot to weld the pin.

Any way I thought it would be a good idea to let you eta guys know that it can be done fairly easy and the 325i flywheel is about 8 lbs lighter then are dule mass flywheels that cant be resurfaced.

You will need 325i flywheel bolts, 325i clutch kit, and I would recommend 323 throw out bearing.

The car realy feels great. I'm not sure if any of it has to do with the lighter flywheel or if it's just having a new clutch.

Except now your flywheel isn't balanced.

You realy think that the pin threw it off that much. I don't feel like there is any vibration at all. I had the flywheel resurfaced.

I like your Avitar. Netfixs just made all the star trek available and I can't stop watching.

Normally I wouldn't care about such a small weight, but the reference pin is on the out most part of the flywheel. That thin spins at 6krpms (or higher). It probably doesn't vibrate enough to matter to you as you drive but it could easily wear out your crank shaft bearings or input shaft to your transmission. Little things add up. I would have had the flywheel balanced while machined AFTER the reference pin was welded on.

I'm probably being overly cautious but do you really want to have to do the clutch job again if something goes south?

[nickflic3]

Wait wth, is there anything out of balance on my i swap then? I used everything from the G260 that was on my eta motor including flywheel. Everything bolted up to the i block though

[shiboujin]

short answer, no. You're fine.

The title of this thread, should have told you, that there's nothing spinning at 6k rpm... :D

^ lol i was going to say somthing about that!

oppS, LETS SEE, could we figure out whats 180 degrees on the flywheel and remove the same size and weight of material, starter teeth come to mind, the back 1/4 of 4-5 should be fine, back meaning the side the starter does not impale said flywheel.

the refrence pin fell out of my flywheel..... could i weld it back on? woulf that be ok?

[shiboujin]

go for it.

[Aptyp]

as long as the person welding isn't an idiot, you can

[shiboujin]

Basically, I can't do it.

Been there, done that. As long as the bead is more of a tack, than a glob, it wont add enough weight to the flywheel to make a damn bit of difference, nor add enough material to freak out the sensor
