flywheel in backwards?

[ChiTownHussla]

Couldnt really find anything like this. I did a swap on my 1g. Engine runs GEAT! Only thing that is bad is that the starter sometimes doesnt catch the flywheel sometimes.

Also, I can warm up the car and everything np, but when I push down the clutch pedal, the engine RPM goes down. The more I push it down, the more the RPMs drop until it dies or stalls out.

I checked by the inspection plate/cover, and saw the flywheel was sparking against the driver side. It was scraping by the flat edge, not the teeth.

Does this Mean I put it in backwards? I will link a video of where I forgot to plug in the MPI fuse back, but this kinda shows the starter problem at least. I know for sure they are related, but dont know what would happen if I DID put it in backwards.

I couldnt get good lighting, so I couldnt get a video of the sparks. But to put it simply its abovve the teeth on the flat surface. Thanks guys ! I tried to be as detailed as possible.

I'm not aware that you can install a flywheel backwards, otherwise you would have no way to mount the clutch?

Give us the rest of the history on this engine,

Sounds like it has a crank issue, with sparks from the front, and the flywheel hitting the block.
Did you just rebuild the engine?
Why was the engine out?

I dont really think it's possible to install the flywheel backwards. It's got to be something else.

Pictures, please

ok guys I will try to take pics later to day. But the engine I bought used from a friends friend in wisconsin. Compression was something like 160 across the board. The reason for the swap is my timing belt broke and all that good stuff.

The best way to explain the sparks, is if you look from the front driver side of the car towards the rear, there is a hole where you can see the flywheel. I see it spinning, no issues. If I tell my friend to go in the car and push the clutch sometimes we get a loud noise like a grinding noise. Other times its just a light grinding noise. I saw sparks the first couple times, but not so much anymore. Maybe it ground some of it down already?

The reason I think its the flywheel is because it only happens when clutch pedal is pressed down. Idle is good and all that. Im lost. I can take it down maybe in the next week or two. Until then I dont have place to do it. Thanks for your quick responses guys.

When you clutch in you release the clutch from the system so you're actually pushing on the pressure plate towards the engine side. When you clutch in, your throw out bearing may be contacting the pressure plate fingers at a funny angle or so and it's causing the sparks. It's weird regardless.

I love this board. Always something new and interesting to read on how a car is messed up. .

Double check to make sure you have all 4 transmission bolts in there and tightened down.

AND the dowels....if they are missing get replacements.

 

[ChiTownHussla]

OK guys I have the dowels. I only have the 2 bolts on the top in at the moment. Can some 1 post up pics on where the bottom two go? I have 2 dowel pins. on on each side. Is that right? Those pics can really help!!! And ya I hear ya.

 

[bryanwheat]

You are going to break the bell housing doing shit like this. You need all the bell housing bolts, no exceptions. Depending on what block you are using there will be either 1 or 2 bolts in the front and one in the lower rear. Also do you have the starter plate installed?

 

[ChiTownHussla]

okay I have a six bolt block. and yes I took the starter plate off my broken engine and placed it on here. I lined it up with the dowel pins and the top two bolts. I couldnt find the holes for the other ones.....I even bought the bolts from the hardware store to put it in, but never found the right holes..

don't have pics, but the dowels sound right. You really need to have those bottom bolts in - without them the bottom of the tranny will actually separate from the block when you hit the clutch - leave it long enough and it will actually break out the top bolt mounting locations.

One bottom bolt should be in the general location of the slave cylinder but towards the passenger side of the car.

Another actually is inserted from the drivers side of the car (all the others go in from the passenger side towards the drivers) and it is the skinnier bolt - it goes in at the back of the motor underneath and close to the starter.

I wonder, as others mentioned, if you have something going on with the TOB - that could be the source of sparks/noise/friction mentioned if that has gone south. There could also be an issue with one of the fingers. You really should pull the tranny off and take a look.

I have in the past used a engine hoist and hung the tranny from a homemade plate attached to the shift cable mounts - this let me slide the tranny back from the block and do an inspection without having to wrestle with the tranny deadweight or remove it completely.

The lower bolts go thru the dowels. IF you know where the dowell is than you can find the holes for the bolts. The rear bolt goes in thru the engine and threads into the transmission. It is an 8mm bolt opposed to the 10mm bolts that are in the upper and front holes.

 

[ChiTownHussla]

Well I know for sure its the flywheel. I saw it myself. I am here to see what can cause it. The dowel pins are the silver looking cylinder things right? I used those and never had any bolts in there even when I first bought the car. Any pics guys?

 

[bryanwheat]

Just look at the transmission and block where the dowels are at, the hole is right there.

 

[NOSLO2PT0]

You are missing 2 bolts. A total of 4 bolts hold the transmission to the block. two on top under the head. Another one of same size, but about 3/4" longer, goes right above the slave cylinder. Then there is the tricky one. The bolt head faces the driver side, and the hole is directly above the driver side axle, where it enters the transmission. It's a 12mm head. bolt is about 3" long.

I had the same problem with rpm's dropping when clutch was pushed. Ended up being a bad pressure plate and my motor soon crankwalked. dont do that too much, .

 

[ChiTownHussla]

Pressure plate huh? and does anyone know what size I need? Could these 2 bolts really make it this bad tho.? I think the guy who said the PP is ###### right.

If you don't have the bottom bolts it will flex the transmission and break the case, you HAVE to have them. Put them in and see how it does. You need them anyways. If you don't than you will have a broken transmission and be posting a new thread asking why in a few weeks. The reason that it is dying when you push in the clutch is because the transmission is flexing and the flywheel is grinding against the case of the transmission.

 

[ChiTownHussla]

Ok cool. Does anyone have pics to reference location of these two bolts? And how bout the bottom two bolt sizes? I know rrar one is said to be smaller in size

 

[Spyderman7]

I was trying to figure out why you were getting sparks and it came to me You got to put the tricky bolt in that goes in the back below the starter or your flywheel will rub the T-case.I have seen other people do the same thing and they thought there new motor was locked up and it was that they forgot to put the little bolt in the back.

 

[ChiTownHussla]

anyone know that bolt size? and ya spider you're right. this is exactly what is happening

 

[Vladimir]

its very unlikely that you can put the flywheel backwards, i dont even think its posible. Maybe you put a flywheel from another car or something, but if it will be rubbing and sparking against something that should make a lot of noise. Maybe you didnt bolt something right. But whatever it is, you should stop running the car. Take it apart and look at it, if not you may end up needing a new tranny or motor ( if its not balnced properly you can chew up the main bearings and the thrust ). I never heard of a problem like that. The car shouldnt shut of when the clutch is depressed, the only thing that goest in my head is that your tranny is jamed somehow and when you put load on the input shaft it gets stock. Good luck.

 

[ChiTownHussla]

Well before I knew about the sparking and stuff I did test drive it. Other than the grind, car ran ok. I ran thru the gears down my block. Got up to third np. I am going to put in those bolt I just need to know thirr sizes. And is it possible to see the tranny flexing? Because my friend pushed down the pedal on the lift while i was under it and didn't see any play. Jw
