Starting to wonder if my trans is what caused my main's to fail, or possibly whats causing my alternator belts to fly.

maybe under high load situations and high rev, it creates a nasty amount of movements with my main shaft in the trans which is sitting in the center of the flywheel & directly connected to my crank... (just thoughts that are turning in my head)

 

did you try to call meh?

 

Come to think about it that can be your problem. I have talked to a tuner, and he was talking about how many oil pumps and main bearings that get blown apart from using a CTR pulley, that they lack the little bit balancers that the stock pulley have (the rubber part i showed you at jarfro's place). And it being so small it cant compensate for the large amount of vibration having a bad input shaft bearing will cause unwanted vibration in the motor, which in turn will kill bearings. That is one reason why i want to get the ATI super damper for my build. Just something for you to think about. There is a reason why V8's uses balancers.

I did a accord that had a bad pressure plate and i remember how much vibration that caused.

 

yea call me some time this week.

thanks for the input.. i'm really thinking that i killed my main's coz of the tranny. It's seeming very possible at this point.

 

your main engine bearings?

 

yes, long story.. gimme a call tomarrow night for the cliffs

 

:noes: dude, let's hope not :hs:

 

Hey!!! 500 hp problems are 500 hp problems. What you drive is irrelevant. I know... I'll get all emo, and you can bring the salt.

lol

 

A little knowledge from a DSMer... If this were true, your engine's thrust bearing would be hosed. If you're thrust bearing were hosed, then you would have crankwalked a Civic.

:gtfo:

I didn't see that kind of wear on your thrust bearing. I saw squished mains. I'm stickin' to the soft bearing + 20 PSI beating theory. Anything laterally affecting your crank would not have squished the mains like that. It would have eaten through the thrust bearing first.

I've fragged 3 transmissions' thrust bearings, blown 1st and 2nd apart, shatterred my shift forks, and fired a chunk of something out of the tranny case... and all the while running an ACT2600 extreme clutch. I have NO crankshaft endplay. But I do have hardened bearings that are designed for a turbo car.

 

i understand what your saying but you also have to remember that there are many differences between how the two transmissions are designed. The only way my thrust bearings would have got chewed is if the main shaft in the trans had the avalibility to show end play durring the turbulance. There are to many parts in that thing to restrict end play in this trans, including the case plates & a ring clip to hold it back, let alone the fact that one of the gears that meets our final drive are riding on a washer thats already touching the case. It would be very hard for our manshaft to have any end play (in & out) to effect the thrust bearings on my motor. But the verticle wobble of the mainshaft is definatly possible through the off-set of the two shafts.

just some food for thought.


*edit: on a side note. I tore down my extra trans to change the input shaft bearing in it coz it's gonna be put to use while i'm fixing the one thats in the car. I'm thinkin i'm gonna toss my extra LSD in there as well & put it back together. I found the input shaft bearing in a different trans that had a cracked case. Cross referanced the part numbers and they came back the same so i didn't have to buy parts yet!
