I posted in the transmission section, and hate to be the guy that posts two threads for one question... Just hoping to figure this out ASAP and I'm afraid no one cruises the transmission section much. If it's an issue, no problem deleting a thread.
I just put a '94 4.0 with mazda 5 speed in my '86 Bronco 2.
Pulled the engine and trans from a parts truck, and was told by a honest lookin' dude that the engine and trans worked great, and trans had a fairly new clutch.
Engine runs great indeed.
Well I went to drive it and quickly found out the clutch is not disengaging at all. Clutch in, try to shift into reverse, gnarly grinding. Won't go in any other gear unless engine is off.
Pulled the slave master and made sure it was bleed properly, no air in the pocket of the master cylinder or anywhere else. Pedal feels good.
Read about people having problems with clutches freezing/rusting together after sitting. My transmission sat outside for a bit so figured i'd give it a shot. Started it in gear, drove it around revmatching gears , bogging and stomping throttle with clutch pedal depressed trying to free it up. I don't think this is the issue, it surely would have freed with the abuse i gave it doing all this.
I can get under it and watch the throwout bearing move as my buddy pushes the clutch pedal. Is it moving as far as it should though? Couldn't say. But i can see the diaphragm getting pushed in.
Only thing i can think of is if the bronco 2 2.9's master cylinder doesn't move enough fluid volume as the 4.0 master cylinder. After hours of research though, this does not seem to be an issue.. or atleast in the hundreds of 2.9 to 4.0 swap threads, i've never seen it mentioned, and you would think surely someone would bring this up.
Regardless, i welded an eyelet off of another master cylinder pushrod to the end of my eyeley, and used the new extended eyelet to see if 3/4" longer pushrod would push more fluid and disengage the clutch. No difference.
I'm lost, and getting pretty frustrated. Afraid to drop the transmission because i can't think of what would be wrong in the bellhousing. I was checking out the throwout bearing when i had them separated and would have noticed if something was obviously wrong.
Thanks fellas. I'm going crazy over here.
