Partially Attach Flywheel

go.stfu · 10-09-2007, 04:51 PM

Is it safe to attach the TC to the flywheel by only 5 of the six bolts for a 15 minute test to see if the engine is working?

One of the holes on the flywheel was bent by a screwdriver holding the wheel in place.

In a week I'll have a new flywheel but the engine must be tested in the next couple of days.

Thanks for the info.

Ehhh... i dont think 5/6 bolts is safe, it wouldnt have the same pressure all around, which would make it uneven and possibly dangerous, IMO.

best to get a 3rd opinion here.

I'd agree... The 6 bolts would keep the torque converter flush against the flywheel. With only 5 of them, you run the risk of something flexing, and probably causing some damage.

Went and grabbed one off of ebay -- decided the risk probably wasn't worth it.

i dont see what the big deal is if your just going to start it and let it idle... flex plate should not be moving that much at lower rpm

the big deal is that if your flywheel isnt properly attached, even it it doesnt move that much, it still runs the risk of wobbling and you REALLY dont want that because it will just cause needless damage to your vehicle, its like... trying to drive with 3 wheels on your car. you CAN do it, it just isnt Safe/good for your car.
