Never had a single issue with installing dozens of them. Take a piece of sand paper and clean out the crank, blow it out with air and then tap the new bushing in with a 15mm deepwell socket. That's all you need to do, if you're breaking them after that the crank has a burr or damaged spot on it.

which bushing are you talking about?

Enjin

08-08-2006, 03:58 PM

its the bushing behind the flywheel. there is a little hole that you slide a socket looking bushing into.

and unless nico has failed me, then I am installing the right one... because it says that you use (for sr20det engine) a pilot bushing for 93 240sx.

KA24DE pilot bushings are the same as sr20det. I just hit mine in slowly with a 14mm socket. DO NOT GO ALL THE WAY IN!!!. make it flush with your flywheel.

nico failed me? those bastards!

I forgot about the flywheel... maybe I could bolt that on... and then that would help the bushing slide in better.

On my CA18, I had to push the pilot bushing all the way in. The tranny would not go on otherwise.

Nissan pretty much uses 1 pilot bushing for every motor for a span of 20+ years.

Some grease would help too. Just be careful not to get the grease on the flywheel after you get the pilot bushing in. Spray the fuck out of it with brakecleen once your done.

ummm.....you're not supposed to drive the pilot bushing all the way into to till it stops? Shit.

Is this right? Hope not.

Id be careful with the Grease.

But anyway, yea, i was freaked out when i had an old stock datsun pilot bushing, but just make sure its going straight in, use a little rubber mallet and go slow, just straightness is key.

Nope...You're only supposed to use engine oil on the pilot bushing. The pilot bushing is porous, so grease should not be used at all.

Either soak it in oil or dip your finger in oil and rub it on the inside of the bushing until it starts to weep out the outside of the bushing.

Also there are tools designed specifically for installing these bushings.

Actually the FSM (93-94) calls for "lithium based grease including molybdenum disulphide"
And it should be apllied to the input shaft tip, down the shaft grooves, and in the recess of the throw out bearing during replacement.

Oh, and the pilot bushing should be driven all the way in, until it stops.

My last post was based on the FSM instructions and diagrams. Sorry I don't have a copy of it right now to post the pic here.

Trust me always go by the FSM. So YES push it all the way in until it stops. I'll try to post a pic later tonight.

Don't mean to ask the stupid question but you never specified... you did take the old one out right?

"Is there any confirmation about the pilot bearing being all the way in?"
I'm doing an SR swap right now and tried test fitting the trans b/c I know it's not from that motor. It would go on all the way but about an inch and I tried rotating it and all that good stuff. So I thought the clutch was misaligned. Since that is going in my personal car, I put on a new clutch, flywheel, and pilot bearing. Come to find out, the old pilot bearing would slide from all the way in to flush with the crank. All my other swaps never replaced the pilot bearing. Right now mine is flush and tight....Should I knock it all the way in??

Is this why the trans would not go on all the way before "like one inch away"?b/c I could take my finger and push it all the way in and pull it flush?...the new one from the exedy stg 2 sits in there tight.

I just gave you confirmation. I looked it up in the FSM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!

What more do you need? Look if you pull the pilot bushing out, check the inside of the crank. You will be able to see AND feel and ridge about halfway in. You drive the pilot bushing in until it hits that lip!! The lip will make it stop at it's necessary depth.

For all you guys that keep saying to "leave it flush" and "don't push it ll the way in". WTF??????????????? I hope you guys are not implying that you are trying to push it ALL the way in until it hits the back of the hole! That would be damn near impossible without destroying the bushing. And even then....the hole is so snug already there's really no room for error. So if your pilot bushing doesn't fit into the hole nice and snug (too small or large) then it's the wrong one!!!!

Pilot Bushing -

To my amazement, per FSM, it says to install as such...

http://i7.photobucket.com/albums/y264/Cdoria/PilotBushingCorrect.gif

ALL THE WAY IN! All this time time I always heard and performed flushness, I was wrong.

Forgive me Dream240, it is a lesson well learned.

You have to be able to fit the bushing on the end of the shaft.

ok so I am on my 3rd pilot bushing. I wish I hadnt taken the old one out.

the thing just does not fit!

every time I try, it warps or breaks. its almost comedic. anyone have any tips for making it work? its the only thing that is standing between me and a running car. ^_^

was your motor matched with an auto tranny previously? if so, you have to take off the spacer on the back of the crank. with this on, you can fit the pilot bushing in, but its hard as hell and ruins the bushing. it looks like part of the crank, but its not.

At every bushing change, I polish the hell out on that hole with a dremel
Not sand or grind, POLISH
I also polish the outer part of the bushing and apply some light oil.

Don't know why you would do that. The bushing is not meant to rotate in the crank, hence the tight fitment.
By polishing and outer lubrication you could be allowing the bushing to start to travel in the hole. THAT could lead to scoring and premature failure. Keep in mind I have no concrete facts.....just using the old noggin. Seems logical. The FSM doesn't call for any polishing, also it only calls for lubrication on the shaft, thus the inside diameter of the bushing. Not the outside, or the hole for that matter.

So polishing might be a bad idea.

Yea that seems logical, im currently taking my auto one out and swapping in a manual one. Bitch is hard to get out

Just to be sure that the area is clean and free of any dirt or residue.
Is a bronze part, so as soon as heats up, will conform the the part.
Also I spin the bearing on the shaft itself just to verify that will fit perfectly.
As for the bushing backing up, quite imposible, there is no room for the bearing to back up.

going 5 speed and this thread is giving some good facts, thanks. first of all. now what is the easiest way to remove the a/t pilot bearing, some say dremel, i have the pilot remover tool w/ slide hammer, but thats not working

Dream240

01-08-2007, 06:06 AM

Well, I used the dremel just because the hydraulic method didn't seem to work. But that' prolly cause I initially used a chisel and tried to cut it out. THAT was useless.
If you have a dremel with a grinding wheel, should take about 30 min to grind down one area then just grab it with some vice grips and collapse it in on itself. Then pull it out. You don't have to grind it until it you go through it. Just grind it down till it's really thin then bam, done.

how much damage, can the inside where the bearing sits, take?

Dream240

01-10-2007, 07:57 AM

umm....well you don't want to grind it up with a dremel if that's what you're asking. I would say a couple of knicks won't hurt anything but just make sure to flatten out any rough spots so that the new pilot bushing will go in smoothly. Any burrs inside there will cause it to get hung up.

Why do you ask did you jack it up with something? :o

seriously? :keke:

- Lines are removed and tossed

- MT tranny doesnt get a cooler

Also on the pilot bearing you can remove it by;

- putting some grease in there and using the clutch alignment tool and hammer the tool and it will push the bearing out

- use a dremel

- use the pilot bearing removal tool - that usually doesnt work

- take a 3ft 3/8" extension - stick the female end in and pry back and forth up and down evenly all around - it will pop right out

As an update - I just got done with one - I finally got lucky and got the bushing removal tool to work and pull the AT bushing out - but then messed up a MT bushing and couldnt get it out - trying the socket trick (another bad idea) - grease trick does not work - the guy who said it did I would like to kick him in the ass!
I had to remove it by chizeling it out with a screwdriver and a hammer - but be very careful to not scracth the inside of the crank!
The bushing is very soft metal so it not hard to chizel.

The best way to install the pilot bushing is to get it started by hand and make sure its straight!

then take a board and use a hammer - tap it in as far as you can with the board -No pounding here! you dont wanna warp the bushing!
Then use an old alignment tool to hammer it in the rest of the way!

If you can get an old no good tranny - cut the end of the shaft off - that would be the best tool to use to install the MT pilot bushing!
