stickedy Posted November 12, 2006 Share Posted November 12, 2006 Yesterday my brother and myself swapped the engine in my EA82 back from carbed to MPFI, everything works fine, the engine fires on at frist try, but when I want to drive it out of the garage, nothing happens... :-\ Let me just list what cars were involved and what we have done so far: 1. My daily driver: 1989 EA82T SuperStation with 5 speed MT, permanent 4WD. 2. My old daily driver and donor car of that carbed engine: 1986 EA82 Wagon with 5 speed MT, part-time 4WD with push-button. 3. Donor car of that MPFI Engine: 1993 EA82 Station with 5 speed MT, part-time 4WD with Dual-Range. So bach in March, my EA82T engine breaks down (most likely head damage) and because no other options were available, we but that carbed engine in that car. Transmission and all other thins stayed in that car. We had some trouble to get the ignition working, but figured it out and everything worked fine so far. So, in August I bought a real cheap donor car with MPFI engine (I've posted it here somewehere) and drove it for about 400 km through half Germany and didn't notice any clutch problems or so. In fact the car runs very fine! And because next year I have to make an emission test and the MPFI works better in cold winter (I hate this semi-automatic choke), I wanted to swap back the carbed one to MPFI. So we pulled the carbed engine and pushed the MPFI one in the car. Since everything of that donor car worked as it should, we decided to insert it with its original clutch. But now, the clutch doesn't work! It just isn't engaging and always in the state as being depressed or in neutral/idling. So this whole thing is somewhat mysterious. We tried to adjust the clutch, but no success. I didn't expect such a problem and really don't have any idea why this happened. So, can anyone explain what could be the cause of this problem? I had the idea that the transmission shaft of that 1993 transmission is somewhat thicker and that my 1989 tranny now doesn't have a connection at all. But I didn't hear of any changes of Subaru in that way... So pulling the engine and swapping the clutch will be the thing to do if there isn't another solution of this. Some more work to do... :-( Link to comment Share on other sites More sharing options...
Cougar Posted November 12, 2006 Share Posted November 12, 2006 I don't think you have any other option with this delemma. The shafts may be different sizes. Link to comment Share on other sites More sharing options...
kayakertom Posted November 12, 2006 Share Posted November 12, 2006 If your clutch pedal is not returning, that could mean the clutch cable is binding or is kinked. Link to comment Share on other sites More sharing options...
NoahDL88 Posted November 12, 2006 Share Posted November 12, 2006 The EA-82 shaft, and the 89-94 legacy shaft are the same diameter and spline count, so it shouldn't be a problem, unless the donor and recipient rigs are 2wd vs 4wd, but even then i don't think that would be different. If you swapped in the part time gearbox, you need to make sure its either in 2wd, or 4 low or high, cause if its in between selections it will act as if its in neutral.

Yeah, that was my thought, too. And all three cars were/are 4WD... If you swapped in the part time gearbox, you need to make sure its either in 2wd, or 4 low or high, cause if its in between selections it will act as if its in neutral. Urghs... I left the all-time 4WD transmission at its place. But this one is also Dual-Range and has low and high. What will happen if that lever is in a position between that two? I ddidn't check this yesterday... I don't think you have any other option with this delemma. The shafts may be different sizes. This shouldn't be possible. As NoahDL88 writes, even the first Legacy engines have the same diameter. But I will pull the engine again on Tuesday and then we will see... If your clutch pedal is not returning, that could mean the clutch cable is binding or is kinked. Yeah, good idea, but the pedal works flawless as it should work. Thanks at all!

stickedy Posted November 12, 2006 Author Share Posted November 12, 2006 Thanks man!! That was the whole problem... I feel like an idiot :-\ I drove the car home a few minutes ago. Don't know why this lever was in "neutral", but it was there. Now everything works fine so far. Thanks one more time for this great hint!! We would have pulled the whole engine again and searched for any mistake or damage and would have spend hours for just nothing... Link to comment Share on other sites More sharing options...
NoahDL88 Posted November 12, 2006 Share Posted November 12, 2006 I only know about that cause i've been that idiot on multiple occasions. Congrats on the swap, now enjoy it. Link to comment Share on other sites More sharing options...
