Anyone using PCI RTA bearings? They said that they would work on a crx si but i just found out the hard way that they are too big to fit into the sleeve.

these are the measurements i got... i dont think a press is making up the difference of a 1/4inch.

CRX Si RTA diameter .....about 2 3/4 inches
DA RTA diamter ....about 3inches
Old style PCI-PWJDM bearing housing ....3inches
New style PCI bearing..... ? inches

I would like to know if someone else has had this problem, or if anyone else has installed these on CRX si RTA's before without a problem.

 

I recommend calling Kiwi or Eric at Special Projects.What model do you have Red or Black? IIRC Password TA bearing are made by PCi,I know them both personally.The second Gen bearing kits(Black) are a tad smaller diameter as to not require a press for installation,to make user friendly for ones witout access to a press..Just drill the 2 holes and install the allen bolts as the older model(red).I hope this helps.

PM me if you have any more questions on this.

Hi, in my CRX H4 racecar I'm using the PCI RTA spherical with the old-style mounting (i.e. the ears in the spherical housing) and they work great. With the old-style, you much remove the entire bushing and sleeve to be able to fit the PCI unit into place. Thus, the PCI unit presses directly into the RTA with no sleeves.

 

The kit I have is the Black set, password said that within the last 6-8 months they have come out with a newer version. im not sure of any specs on them, but he did say they are bolt in, not press in.

I have everything removed, I had the bushings removed and the entire arm sand blasted and powder coated (no powder inside where the bearing goes) so i know the opening is as clean as it gets.

I may have to send these back and try the newer versions. i would love to get someone on the phone, such as Brian from PCI... or anyone else who could help me out with this. I appreciate your quick responses.

We will get you fixed up.Tell them Justin sent you.

 

thanks!


Okay, Mike at King motorsports was very helpful... he measued the mugen hard rubber bearings for me....

3.15 for a crx
3.36 for a DA

theres really only 2 options on a RTA bearing he says.

My RTA bearing inside diameter is about 2.97 inches.

PCI Bearing are about 3 inches...
theres a newer style out which is a little smaller i hear.. so i think that is what I need.. or maybe my RTA is not a CRX or DA arm... Hope Brain from PCI gets back to me soon.

 

When you say with NO SLEEVES.... the only thing left is the welded on(so it looks) sleeve that is about an inch wide.. almost looks like someone stuck a pole through the trailing arm.. that piece looks like it has to stay.. are you saying that has to be removed? any pics of a gen2 PCI bearing installed?

 

The housing the new PCI RTA bearings have the exact same specs as the old previous black design. The only thing redesigned was the offset shaft and offset bearing that offers less bump steer.

I know many people have installed these on a CRX with a few modifications. I do know Brian personally and I will let him know about this situation.

How about getting us a picture of your arm, that will help us see if you still have the old sleeve from the bushing in the arm, sounds like you do from that discription, if that is true, then it must be removed.

Good catch,that sounds like the issue from his last post.

I know someone can find the link for the bearing install How-to prkiller did that was on here. The TA is tapered dont forget.

 

JW racing, found that for ya!

Thanks! I left him an e-mail with my phone number. I really want to use these bearings!

Im positive I have Everything removed... I mean, it went through cutting the rubber out, laying it over fire to burn the rubber out, hit it with a wire brush... and then had it sandblasted... that hole is gutted! ill get some pics up for some better idea... I really appreciate everyones input.

 

I know for a fact, since the CRX rta's are a bit different the EG/DC/EK so on... there does need to be some slight modifications made. I will look into this for you asap.

You need to press out that bushing sleeve. If all you did was remove all the rubber, there's still a steel sleeve in the arm that needs to be pressed out. The "pipe" looking thing that you describe above is the sleeve for the bushing that needs to come out. Then you PCI sphericals will fit the arms.

Here's the best 2 pics I could find in my album to show what the spherical looks like in the trailing arm:

 

Winner Winner chicken dinner, because you burned out the bushing, you may have thought that cylinder sleeve was ment to stay in, it actually needs to be removed. take a sawzall and cut a few openings in it, and take it out. Problem solved.


joe

 

haha i was thinking he left the sleeve in there also

 

Hi dan, Brian from PCI it sounds to me like just the rubber was removed and not the entire ta bushing. that hole that looks like a pipe that your measuring needs to come out. now if you have the old red ta bearing it will need to be pressed in from the outside of the trailing arm. If it is the new black housing it will be installed from the inside of the trailing arm.

dont cut it out! just take a hammer and wack it a few times from the INSIDE ONLY! and it will come right out.

 

Thanks Brian. and everyone else...

Brian, on the directions it says in bold "make sure the arrow points up" I dont have an arrow on my bearings... is this for the newest model maybe?

whats the difference between the model I have and the newest model?

 

Yes the instructions your reading are for the latest version. The difference on the latest version is the trailing arm doesn't need to be removed, its a dirrect bolt in. Also the bearing housing and shafts are offset to correct the angle of the tow link. The new design corrects the bumpsteer problem.

 

have a pic of this?

 

Anyone know if these will work on Drum brake TA's for a 89 Civic Si? The Password site says no?

 

Yes they will

 

All '88-00 Civic/CRX/del Sol trailing arms use the same bushing, along with '94-01 Integra and CR-V.

Only '90-93 Integra uses a different bushing.
