I've been helping my son with a swap in his 93 Civic. He bought a 92 Integra with a b18a that he drove home but was rotted out after his motor jumped time and destroyed the engine. He got a new 2 stage clutch kit from Fidanza (clutch,bearings,and flywheel) and put it in but now we can't get the clutch to disengage. It seems/feels like the release bearing isn't traveling far enough to disengage the clutch. We have pulled the tranny off again and found the release fork spring was broke but I don't see that as a problem with the clutch not disengaging. The new clutch and flywheel seem to be about an inch smaller/shorter than OEM. Would that be enough to cause that problem? Any input I get will be greatly appreciated. Thanks in advance.

 

Diameter of the clutch won't matter as long as it matches the friction surface of the flywheel. Flywheel can't be changed as it has to be able to engagable by the starter. What transmission is he using? If its the B18A trans, what conversion kit is he using?

The fork spring will matter so replace it.

 

Aquafina, thanks for the reply.The tranny is from the Integra. The clutch kit is F1 RACING STAGE 2 CLUTCH FIDANZA FLYWHEEL 92-93 INTEGRA which was bought on ebay from grip-force clutches. The size difference is not the diameter its the length. The engine was installed and ran fine, it felt like the bearing isn't traveling far enough to engage the diaphragm spring so I'm guessing it's the difference in length of the frlywheel/clutch.

 

What conversion kit are you using for the trans? Or was the car converted to cable?

 

We converted the car to cable. It really wasn't that bad. We had to do a little fabricating to install the Integra's clutch pedal and drill a hole for the cable to go through the fire wall. I don't believe that has anything to do with the clutch releasing since it will pull the release shaft up to the braket to mount the cable.

 

Cable clutches can be a paint if they're not adjusted right. Make sure you only have about 1/2"-1" of freeplay on the clutch pedal.


If there is none or too much, you will run into disengagement issues.
