So Im about to put the tranny up and the input shaft bushing* isnt fitting in the crank shaft. Nor will the input shaft actually sit in it once its in either. I dont remember putting it in my max and its been fine.

But nforces is a VG with a VE tranny. I think it will be fine but I dont want to screw up his stuff.

*May not be the proper name, I just drew a blank when I went to post...

It's called a pilot bushing..

I'm not 100% on this one but from what I've heard you almost never need to change that out, at least I didn't and no problems here...

On a 3 gen, they don't really matter since the end of the input shaft doesn't actually ride inside or on the end of the crank. on my 240, the input shaft has a smaller end on it that actually slides inside the pilot bushing. this helps keep the shaft centered during use and from vibrating its brains out at high RPM, causing bearing failures in those types of transmissions.

The VE/VG trannies don't use that type of shaft, so the pilot bushing really isn't needed. just make sure you remove the old one from the auto crank if you have one in there. the auto bushing is much larger and WILL hit the end of the input shaft on a 5 spd tranny.

but you still need it because that is how you align the clutch. The clutch centering tool has to slide into the bushing. That is the only reason I put mine in when I put my auto motor in my 5spd car.

Just wondering, how do you go about getting those in, you have to press it somehow? I got a new bushing with my new clutch but left the original in there.

i think i did it w/ hammer and a block of wood

I just left the original one in there..

Ive never put one in my max. But in my 240 I froze the bushing then used a hammer.

Bah. I aligned mine with a bolt and random parts in my junk bucket.

but yes, you're right. would be easier to use the right alignment tool.

Alex_V

Those things suck any way. I always align them by eye. I look at the disk on the FW before i put it on. It'll have say 3mm around the diameter of the disk to the ridge in the FW, so once on Ill make sure its even around the disk.

nforces tranny went on perfectly as did my max's and my 240s wasnt as easy so it works for me.

what...how do they suck? Mine fit perfectly snug in the splines and perfectly snug in the bushing...how does that suck. To me its a very fast perfect solution to putting the clutch in. To each his own but just because you don't like using a tool doesn't mean it sucks...especially one that makes your job easier.

is there an easier way to get the pilot bushing out. none of the shops around me have a puller small enough so i end up having to thread the bushing with a huge bolt and the bolt will press up against the end and press it out

well the consensus is that there is no need to replace the pilot bushing since the only thing its really used for on the 3rd gen Maxima is to help you align the clutch...unless you are going from an auto to a manual then you need that bushing out.

That said I borrowed a pilot bushing puller from autozone to get my auto bushing out.

x91max

what would cause sufficient wear on this bushing then? when i changed my clutch it was so thin on one side i could break it with my finger.

dont know because the input shaft doesnt ride in it on a 3rd gen.

digging up a thread from the grave... i haven't noticed any problems explicitly caused by not touching any bushings at all on my swap... a/t crank is as it was before, and the pilot bushing for the m/t wouldn't go in anyways b/c the hole was too small from the a/t bushing for it to fit. but unless that's what's causing heat on my clutch fluid, transferred up the metal pieces and such until it reaches the slave cylinder and heats that up.. then i notice no effects.
