RB25 Neo Clutch Mystery! help help help! especially Carl H, coolwhip, or s14-neo

To: Carl H, coolwhip, or s14-neo...

I have been trying to locate a part for my clutch for a while now and have not had any luck. Im in need of the part that holds the release bearing to the pressure plate. it goes into the hole where the pressure plate fingers are. Its supposedly called a "Wedge Collar". I tried cross referencing the part to an 04 pathfinder 2wd VQ35 at the dealership and found the part on an "all data" database but the dealership cannot figure out what part it is and gave me a whole new release bearing. which is the same on that pathfinder by the way.

any info? heres a pic of an aftermarket clutch kit with the piece installed on the pressure pate that im missing. i really dont want to have to buy a whole new clutch kit for $1300! (its a pull type in this car BTW). Same clutch in R33 GTR and BNR34, and my ER34.



(its the ring in the center of the pressure plate that looks like a gear.

and here is my setup... cant see the part but it holds the two together

i've no idea man...ive never delt with the pull type clutches.

[S14-NEO]

check with RBmotoring...they may be able to helpy ou out with that...all of the R34 GTR's use the pull style clutch like the neo. and they specialize in GTR's..worth a shot. as for me im running an Exeddy twin disc.hehe

[sickness14]

[Coolwhip]

Another reason why I have always hated NEOs.

blah! I love the NEO. In this case it's just a wild call for a part that usually is replaced with a clutch upgrade, just a sticky situation.

However, OP whats this talk of you finding a x-ref part for that with the Pathfinder?

yeah man, i did a cross reference using "ALL DATA" program for technicians and found that an 04' pathfinder 2wd 3.5L (VQ35) has the wedge collar in the picture of the exploded view on the clutch setup. however, i took this to the dealer and they had a totally different pic on their computer

so close, yet so far. i emailed exedy last night about purchasing a pressure plate from them without a whole new clutch setup as i already have a clutch disc.

thanks for the help guys!-John

im going to ask this question that hasnt been asked yet...why do you need one of these collars..they are reusable,(unless you didnt know how to get the transmission off and ended up prying it off....there is a real simple way of releasing that thing when the transmission is still attached. all you need is a long screwdriver (flatblade) and release the locking mechanism from the pressure plate fingers.

*points and laughs*

[gawdzilla]

do you know if this part is sold with the pressure plate or with the throwout bearing?

The transmission was not removed by me, but by a shop my car is at. the piece is no longer usable, or else i would not be looking for a replacement. Im not sure if it comes with the pressure plate, as i cant locate a diagram anywhere. I ordered a release bearing from the dealership meant for a pathfinder which i thought was a pull type trans, and it didnt come with the wedge collar. I may be looking at a replacement clutch from exedy if i cant find this piece, or at least a new pressure plate from them.

bigger problems now though, my head is CRACKED according to the machine shops findings when pressure testing the head and doing a valve job. its cracked from the center of where the spark plug threads in across to the exhaust valve seats on a few of the cylinders. NOT GOOD. now im looking for a replacement head and having no luck.

I may use a regular S1 or S2 head if i can, and swap over my cams, solid lifters, ect. if its possible to retain VVT and the use of my R34 Power FC. not sure if its possible but im running out of options and money. any suggestions?-John

[Carl H]

you might be able to use a normal r33 head but with the solid valvetrain of the neo i am not sure...it would be good if you could get a head and compare.you'd ideally have to use a series 2 head as it runs the same coils as the neo where a series 1 head will require the use of older coils and an ignitor.i'd be willing to bet that you could use your neo head stuff in a series 2 head with little issues...sucks to hear the head is cracked tho apparently the machine shop that did the head originally effed it up beyond belief.

[S14-NEO]

its sold witht he pressure plate, the throwout bearing has a small groove in it that just snaps in place into the pressure plate.

[Coolwhip]

if you still need the wedge collar I got you covered.

DUDE yes. i would love a wedge collar! please let me know!!!

hey could you measure the piece for me, ive got one sitting here for an RX7 that may work. ill upload pics soon

Some of the 2x2 pathfinders don't have the heavy duty clutch but the 2002 4x4 v6 should be the exact same clutch as the NEO.

In the future an easier way to remove the transmission from the NEO is to take off the slave cylinder, then remove the fork boot on the right side of the trans, reach in with needle nose pliers, pull the clip pin that holds the fork pivot and let the pivot pin drop into the bell housing. Pull the fork off the throwout bearing and let it drop in the bell housing too. Then the transmission will pull right off without damaging anything.

Awesome thanks guys. ill have to let my shop know the next time they are working on an R34 neo! I actually found an RX7 FD wedge collar on ebay for $5 and got it the other day. it snapped right into place! looks like its going to work great. thanks a lot guys.

the new head should be here soon. my synapse wastegate just arrived as well.
