My pull to push coversion how-to

[fast_s14]

How-to by Joshua Rhoads (fast_s14)This is a how to on converting a rb26dett bell housing pull style to push style.Tools needed:Metric socketsratchet and extensioncrescent wrench11/32" drill bitdrillM10x1.5 tapc-clamp

Parts needed:Rb26 bell housingZ32 front coverZ32 throw out armZ32 throw out bearingZ32 pivot ballfront cover gasketslave cylinder

1. remove the front cover off of the Rb26 bell housing.

2. Clean gasket material off of front of bell housing.3. Remove front cover off of Z32 transmission.4. Remove pivot ball from Z32 transmission front cover.5. Drill the hole that is right above the original spot that the pivot ball came from with a 11/32" drill bit.

6. Tap the hole with M10x1.5.7. Thread Pivot ball into new location. I used a cresent wrench because i had one laying there.8. Install the Z32 front cover onto the rb26 bell housing.9. Install the throw out bearing and throw out arm onto the front cover10. Now align the slave cylinder up on the side of the bell housing.11. Mark the holes to be drilled and drill with 11/32" drill bit12. Tap holes with M10x1.5

13. Install slave cylinder on bell housing.

14. Install bell housing on z32 transmission.This installation will be covered in another how-to.

Nice writeup! You make it sound so easy, like the guys on saturday morning TV. BTW, were you smokin dope on Step 9? I can barely see through the haze

[HxC_Nismo]

hey that bellhousing looks so dam familar lol. im glad it worked out for ya man, good doing buisness with ya. good write up also.

[fast_s14]

Na actually anothoer guy was welding in the background while i was taking pictures. I just caught a little smoke in a few pictures. lol

Nice of Nissan to leave the push-type location castings in place on the bellhousings. Same for the Z32 trans cover. Makes the conversion process easier than one would think.

[fast_s13]

hey josh nice right up.... let me know when you want to weld that front end together

[fast_s14]

thanks tom, im kinda waiting on my motor to get in before we weld the front on.

[bgsr240]

I see you are getting started on the 300zx Josh.

props to you for the creativity/originality.

Here is a document with the part numbers on the 3rd page for the cover assembly, cover gasket and slave cylinder. The new cover assembly comes with the pivot ball and center seal. If using a used cover, it may be a good idea to replace the seal. After all it is rubber and the Z32's are how old now? The part number is 32114-Y4000 and lists for about $4.55. http://www.fairladyzg.com/PDF/PullToPushConv.pdf

Just wanted to say thanks to stealth-z for his help. thanks again man

I'm going to properly articlize this too.

You are quite welcome, I pleased to see information put out goes to good use and is confirmed to work by others. About a month after making the PDF I picked up a JDM center cover. Interesting how the casting for the pivot ball is a mirror to the Z32.

There is a height difference between the JDM and Z32 pivot ball. The washer under the Z32 ball raises it to the level of the JDM. Not that is probably matters much. The way your's is tapped out eliminates the need for the washer.

Here is the Z32 Pivot Ball part number.30537-40P00 Pivot Ball

Do you mind if I use your photos and integrate it into my PDF file? I never have considered it to be finished.

Yeah thats no problem you can use them.

nice writeup, it's pretty easy to do.

actually the height of the pivot ball is pretty important. your clutch may not fully engage or disengage if the pivot ball is not the right height. Same with the TOB. would suck to put it all back together and the clutch doesn't engage right.

When i did this to an r34 rb25 pull trans, i bought a jdm cover. it was about $30, just took a while to come in.

[Stealth-Z]

Glad you chimed in on this one. I have wondered about the pivot ball height for some time. Was not sure if the washer thickness would be that much of an effect on the engagement/disengagement. As you say, it would suck to put it all together and not work right.Do you happen to have the JDM part number?

rb25det push type front cover: 32110-05U11.. about $30, comes with an OEM pivot ball installed too. up to you if you want to change to a nismo pivot ball.

Hey i want "Complicated? Nah its Simple" under my name.

[Bwana]

Done. BTW, the guy who works for me used to live in Hermann, small world...

[styc]

could someone explain to me, the purpose behind this?

[fast_s14]

Yeah i guess it is a small world. what is his name, Hermann's population is only like 2500 people.

[fast_s14]

I did this conversion because the push type clutch i have found is easier to find and is much cheaper IMHO.

[Bwana]

Finally got this officially articlized.

Ok im slightly confused here.

Here is something quoted from this thread zerothread?id=108871

i have an r34 rb25det transmission, not sure if its neo or not. it is definitely pull type. i am doing a conversion to push type so i can use my push type clutch.

in order to do this, the most important part is the front cover assembly. it is about $35, and is a JDM only part. it comes w/ a new pivot ball already screwed in. the remaining parts, c-clip, pivot fork, TO bearing, spring, etc. can be found as USDM (mostly matched against the Z). the entire conversion should cost about $100-150.

you also need to drill and tap the bell housing to flip the slave cylinder around. however, the casting for the holes is already there so you know exactly where to put it.

ONCE you do all of this, you should be able to use any of the readily available push type clutches (namely z32 n/a)

He says its a JDM part?? But from the write up (this thread) it seems like he just takes the Z32 front cover, moves the pivot ball to the other hole, bolts er up and calls it a day am i not correct?

The process would be identical for the neo bellhousing correct?

When i did mine, i bought a new cover (jdm only part) to bolt in. in this thread, the writeup taps the existing push-type cover(step 6). you can do either but i chose to buy the cover because i was worried about the height at which the pivot ball would sit. didn't want to install it and find out my pivot ball sat too low or something.

Ah awsome man thanks for clearing that up. where did you source this jdm cover from? do you have a part number?

[gawdzilla]

rb25det push type front cover: 32110-05U11.. about $30, comes with an OEM pivot ball installed too. up to you if you want to change to a nismo pivot ball.

i posted it earlier in this same thread

[Phat_Optimo]

I'm thinking about trying this. Nice write up!

[BlackRB]

man this exatly what i'm looking for. Thank alot bro.
