datzenmike Posted April 8, 2013 Report Share Posted April 8, 2013 Is this an S13 (240sx) KA motor or one from a D21? Also what transmission??? Quote Link to comment
pekasdam Posted April 8, 2013 Author Report Share Posted April 8, 2013 @510 freak yeah it turned over when we put power to the starter before we installed trans and now it will not turn over manually @datzenmike engine is from a 90's 240 got it from marcosat the sr20 shop in gardena. transmission looks like its from a 90's hardbody Quote Link to comment
datzenmike Posted April 8, 2013 Report Share Posted April 8, 2013 Well no obvious reason it won't work. Was this KA24E an automatic before??? Quote Link to comment
pekasdam Posted April 8, 2013 Author Report Share Posted April 8, 2013 @datzenmike yes the engine was an automatic before Quote Link to comment
Stoffregen Motorsports Posted April 8, 2013 Report Share Posted April 8, 2013 Can you turn it over with a socket on the crank? If you push the clutch pedal will the engine turn? Quote Link to comment
datzenmike Posted April 8, 2013 Report Share Posted April 8, 2013 @datzenmike yes the engine was an automatic before Did you remove the spacer plate that covers the end of the crankshaft before instaling the flywheel? Quote Link to comment
pekasdam Posted April 8, 2013 Author Report Share Posted April 8, 2013 @Stoffregen Motorsports no it wont turn over even when the clutch is engaged. we were kinda having a hard time when we put in the pilot bushing in. the first one was a brass one. it if too tight and ended up breaking. the second one was like an aluminum we got that one in better than the brass one but the trans fit really snug. would that be a possible reason why it wont turn over when tranny is on?

pekasdam Posted April 8, 2013 Author Report Share Posted April 8, 2013 @datzenmike yes it was removed before we installed the flywheel. possible pilot bushing issue? Quote Link to comment
JAKE719 Posted April 8, 2013 Report Share Posted April 8, 2013 Could you turn the transmission over by hand with it out of the vehicle? Sure it's in neutral? Quote Link to comment
pekasdam Posted April 8, 2013 Author Report Share Posted April 8, 2013 @JAKE719 how would i turn just the trans over. ive tried the turning the engine over manually and no luck. and yeah i double, triple checked to make sure it was in neutral. Quote Link to comment

Even if the pilot bushing was welded to the crank and the input mainshaft of the transmission it would still turn over and run. You say the transmission fit 'really snug' ... do you mean the bolts were hard to tighten up? Or hard to mate the trans to the block? As this was an automatic, what flywheel and what pressure plate are you using? Quote Link to comment
pekasdam Posted April 9, 2013 Author Report Share Posted April 9, 2013 @datzenmike the trans was hard to mate to the block and engine came from a 1992 240sx a/t. we used the original plate that was in the trans. i believe trans is from a hardbody truck Quote Link to comment
datzenmike Posted April 9, 2013 Report Share Posted April 9, 2013 Flywheel??? or flexplate??? Quote Link to comment
datsunaholic Posted April 9, 2013 Report Share Posted April 9, 2013 Did you make sure the transmission was good before installing it? You're going to have to remove the transmission. Then see if the input shaft turns, because one possibility is the transmission is damaged and the input shaft is "locked" in place. Even then, though, disengaging the clutch shoudl let the engine turn over. Another possibility is with this frankenstein combination you've managed to jam the flywheel and/or pressure plate into the bellhousing. Or something extremely serious happened in the engine between then and now. But you're gonna have to pull things to find out. Quote Link to comment
pekasdam Posted April 9, 2013 Author Report Share Posted April 9, 2013 @datzenmike flywheel Quote Link to comment
datzenmike Posted April 9, 2013 Report Share Posted April 9, 2013 Agreed, has to come out and have a few things checked. Pictures never hurt either. Sometimes things are noticed that you don't. Could be something simple. Quote Link to comment
pekasdam Posted April 9, 2013 Author Report Share Posted April 9, 2013 @datsunaholic yes the trans was running and fit fine on the other engine. now that engine was a frankenstein thats why i decided to go with another more complete engine. okay i didnt think of the flywheel or plate being stuck/jammed in bellhousing but its possible. thanks. ima have to remove it and take another crack at it.

DottiBlue Posted April 9, 2013 Report Share Posted April 9, 2013 Will it crank with the trans in neutral? Did you pull this plug out of the back of the crank? This is what datzen mile was talking about. Looks like this installed What it should look like. From what you described about the pilot using breaking, I think that adapter is still in there. I had the same problem you had. Problem is the ID of that plug is very close to the OD step up on the input shaft behind the pilot shaft and it galls together. I pulled mine out with a pilot bushing puller/blind hole puller. If you don't have one you can rent from auto zone etc Quote Link to comment
pekasdam Posted April 9, 2013 Author Report Share Posted April 9, 2013 @dottiblue thanks, ima pull out the trans hopefully in the next few days and see if i can get that going. hopefully its something simple like that. Quote Link to comment
datzenmike Posted April 9, 2013 Report Share Posted April 9, 2013 If tight or even welded together with the flywheel and the mainshaft on the transmission joined, it should still turn as a unit. Quote Link to comment
DottiBlue Posted April 9, 2013 Report Share Posted April 9, 2013 If tight or even welded together with the flywheel and the mainshaft on the transmission joined, it should still turn as a unit. If its in neutral or the rear tires are off the ground. Yes? Quote Link to comment
datzenmike Posted April 9, 2013 Report Share Posted April 9, 2013 Yes, same as if the clutch is engaged all the time. As I said earlier nothing seems wrong and it should turn at least. Take apart and all will be revealed. Quote Link to comment
