Shift Fork Pivot bolt....$12 bolt=$1300 clutch...

Anyone else have to replace a clutch due to a Shirft fork pivot bolt going out? Mine snapped in half at 55000 miles, caused the clutch to fry and now I am spending $1300 on a new clutch instead of my rims. WTF?

LOL...dude, i just had to replace the SAME damn thing.

My clutch was replaced at 35,000 miles...and the shift fork pivot bolt just went at 55,000 miles.

$12 bolt but $1000+ in labour to replace...

Anyone know of a more sturdy/stronger pivot bolt?

If this is a really common problem I wonder if it could be grounds for warranty replacement? (Wishful thinking, I know )

thats so true though...so many of us have had this pivot bolt problem now that i'm reading through... i would be willing to approach infiniti NA about this since so many of us have had this problem.

If people want, start replying to this thread with:
-model year
-miles (when your pivot bolt snapped)
-OEM or after market clutch
-any previous transmission problems

If this is a common enough problem, they(infiniti) should be doing something about it.

So i'll start:
-2003 G35
-55,000 miles
-NISMO clutch installed at 35,000 miles
-previous problems with OEM clutch switching between 5th & 6th

Good idea... but unfortunately if you've had an aftermarket clutch involved, Infiniti NA is much, much less likely to take any action. Oh well, can't hurt to compile a list just the same. Might want to start a new thread and if enough people start replying it could get stickied.

We can start a new thread, but until then....

2004 G35 Coupe
55000 miles
OEM clutch, replaced w/JWT and lightweight flywheel once bolt snapped
no problems prior to bolt breaking..

Is this something that Infiniti NA would actually do? And how many people we talkin here? Everybody sign up!!!

same problem. If the clutch and flywheel were new and the bolt snapped, do you need another new clutch and flywheel?

I forgot how it technically works, but when the bolt snaps it causes the clutch to go out pretty rapidly and does a number on the flywheel too. I would reccomend getting a new clutch and flywheel. I got the JWT combo and it is working great. I really think that Infiniti should cover this as yet another person is experiencing this issue...

Do you rest your hand on the shifter while you drive or only touch the shifter to change gears?

Occasionally I rest my hand there, but there is no force applied to the shifter unless shifting gears, so that should not affect anything...

I disagree with that... the shifter wants to vibrate along w/ the engine and shift around as the rear suspension moves over bumps and such. Since it is mechanically connected to the tranny, it needs to be able to move along with it.

I think resting your hand on it is bad for it -- you will slightly restrict the movement of the shifter and wear parts that would not be worn if you did not rest your hand on it.

Just my two cents

I can see what you are saying, but unless I am actually applying force or something to it, I don't see how that can be detremental. I would be in full agreement if the shifter jumped around like 2 or 3 in and I was holding it in place when not in use, but I don't really see how just having your hand resting on it can be that hard on it. If that is the case, then our cars are way to sensitive or my hand needs to go on a diet...

I don't think it is that uncommon or indicates our cars are "too sensitive" or your hand is too heavy. For FWD cars or RWD that have cable-linkage shifters, it is fine to rest your hand on there because the cable will absorb the shock. For direct connect manual transmissions I think it is expected that you will not ever rest your hand on there.

Some examples from a quick search on the internet: "Is resting my hand on the shifter bad? From the WRX Owners Manual: "Do not drive with your hand resting on the shift lever. This may cause wear on the transmission components". This advice should apply to every Subaru MT model. That being said, the safest course of action is to keep both hands on the wheel unless actually shifting."

"You can but it can damage the transmission. By having the weight of your limb pulling on the shifter handle you in turn are putting pressure on the shift fork and the slider. This will cause premature wear on those components. After a while you will start to notice that you get a little bit of a rake when shifting. Or start to get hard to put into gear. It's a shifter not an arm rest."

"Also, you're not supposed to rest your hand on the shift lever. This places
lots of extra stress on the shift forks inside the transmission.

Place your hand on the shift **** only to shift, then remove it until
needed again."

Considering the car comes with a 60,000 mile warranty, I would guess that it was designed to last longer than that. You may have had bad luck with your particular car (Defective part), or maybe riding with your hand on the shifter for 55,000 miles eventually broke something...

In any case, I'd keep your hands on the wheels unless you're shifting or texting... (j/k)
