Crankwalk question

[patthehat033]

Alright so I would like to confirm something about crankwalk. I have read up on it and figured out that it is when there starts to become play in crankshaft.

Two things I need to confirm:

This is resulted usually from bad thrust bearings correct?

Also, if you keep your car under around 300 HP its more likely not to happen correct?

That's the most popular theory, yes.

Also, if you keep your car under around 300 HP its more likely not to happen correct?

That's another theory.

Plain and simple - it's witchcraft. Don't bother thinking about it unless it happens. You can't prevent it.

crankwalk is overated!! (knocks on wood)

Don't think about it bud. ANY motor With a crank can walk. It's just excessive crank end play. Just do what you want to with the car and don't worry about CW.

what makes you ask?

 

[jimbob_843]

Everyone pretty much has their own theory on crankwalk. My 64 just started walking which is supposedly very unlikely. My theory is that it was caused from a miss adjusted clutch over a period of time putting constant pressure on the thrust surface. I also think its a good idea to do final main torquing while pressing clutch to apply pressure to "align" the thrust bearings.

Well I ask because I don't have a car yet, but I am looking to get a 1998-1999 Eclipse (GSX, if I can find one, when I go to buy it) and I have heard about crank walk being more prone in the 2G turbos. So I was wondering if there are ways to prevent it, but it sounds like its just the luck of the draw.

you said it its pure luck.
Plus good or bad maintenance.

 

[patthehat033]

If I hit over 300 HP, what do you recommend I do about the crank walk. What are smart things to replace? The actual crankshaft itself doesn't need to be replaced would it?

if you really want to eliminate the crank walk out of you head, get yourself a 6-bolt block. Maintain a good maintenance and crank walk solved.

I think you worry too much about crank walk.

+1.

Luck of the draw! Keep that 7 bolt no need to swap out a perfectly good motor and waste money. The 97-99 7 bolts use the split thrust bearings and are less common to walk just for some peace of mind. Just because its a 7 bolt doesn't mean it will walk on you. I'm tired of all these crankwalk conspiracies

How hard is it to swap a 6 bolt into a 2G? Wouldn't the engine mounts not line up etc.?

Yes..well I agree I do worry about it, but I don't want my $5k to go to waste.

I didn't know this, are the split thrust bearings stronger?
