Hello all,
How you doing on this fine night!

Well im doing an engine swap this upcoming weekend. It should be pretty cool. We are pulling the old engine, repainting the engine bay, then dropping in the new baby.
This is my FIRST engine swap, and im rather excited!

Just got a quick question. Ive heard a couple different things so im just MAKING SURE im getting this right.

Engine A= Old Engine
Engine B= New Engine

Engine B was bolted up to an automatic transmition. Engine A= that is in my car is bolted up to a 5-speed manual transmition. I am keeping my 5-speed, and bolting Engine B up to it. Engine B USED to be bolted to an automatic, and is now going to be bolted up to a manual. Is there a piece i need to put back into the back of the engine since it is connecting up to a manual now?

I was told there is a peice that is taken out when an engine is bolted to an auto, and need to be put back in when bolting back up to a manual tranny

True?
False?


Sorry if I am unclear!

The flywheel will be different between an auto and a stick...and of course the clutch...other than that im not sure what else there could be.

 

Do you mean the pilot bushing?

 

Pilot bushing, the input shaft on the manual transmission sides into it.

 

Is a "Flex Plate" the same as the flywheel? And could i just take it from my old engine, since the old engine was bolted to the manual tranny?
Thanks for the pictures too, you guys are always a HUGE help =D
So am i going to have to change that pilot bushing thing? I Was not even aware of that thing to be honest with you.


-Andrew

 

Flex plate refers to automatic trannys and a flywheel is for sticks. flywheels are made for the clutch to grab on when you have a stick. If both motor had the same 5 speed on it as you are putting on the new one, then you should be able to use that flywheel no problem. Just make sure no teeth are missing and that its not severly warped or cracked. You may need to get it resurfaced.

 

The flex plate (auto) and flywheel (manual) are two different things. If the flywheel is in good shape, you should be able to reuse it.

Beat me to it, dawg.

Thanks guys!
I completely understand now. And what about the thing the other guy was talking about the pilot bearing or w/e. Do i need to do anything with that?


-Andrew

 

If you are installing a new clutch kit(which would be a good idea) a new pilot bearing is usualy included in the kit along with a new release bearing too. The only other thing you might run into is that engine "B" may require a different flywheel if it is a later model 1 piece rear main.

 

'86-later = one-piece rear main seal.
'85-earlier = two-piece rear main seal.

If your user info can be trusted, you need a flywheel for an '83-'85 f-body V8 application (i.e., "Engine B" = '82 305).

 

Good catch, five7.

Thanks guys, I really appreciate the help!

 

Just out of curiosity
what would happen if i used my 86 engines flywheel for the early 80's engine?

 

It won't even come close to fitting. There is also extra balance weight on the '86-up flywheels that is built into the '85-early crank, so if by some magic you got it to fit, it would vibrate something fierce.

 

You can get brand new flywheels from NAPA for a good deal.

I got a brand new OEM replacement for a T56 for 100 bucks. Everyother option i had was like 300 bucks.

Just a FYI.

 

K cool.
How does this thing look.http://www.partsamerica.com/productd...pe=267&PTSet=A



-Andrew

 

That's the ticket.

 

Thank you, I will order that soon.

Ok, I emailed the guy that I bought the engine from.. just because I knew he said I needed something else. this is what he said.. "it's called a THROW OUT BEARING.. it's a fat bronze Washer that goes in the end of the crankshaft...you need it for the spindle on the standard tranny to rides it in it" Does that sound right? He doesn't have experience with 3rd gens, do things could be a little different.

THANKS!
-Andrew

 

He's wrong, and 3rd gen knowledge is irrelevant. There is a throw-out bearing ("release bearing", as Robert91RS called it), but what he is describing is the pilot bearing. In earlier days, it was a fat bronze bushing, and was therefore a pilot bushing, but 3rd gens (and most "good" manuals) use a pilot bearing as RK82 pictured above. (And, just in case it wasn't clear yet, auto transmissions don't use a pilot bearing/bushing - you won't be replacing it, you will be installing it.)

It would also be a good idea to replace your throw-out bearing while you have things apart. It may also be included in a complete clutch kit - know what you are or aren't getting.

 

OK so this is what i am getting out of all of this.

I need a new flywheel= http://www.partsamerica.com/productd...pe=267&PTSet=A

I need a Pilot Bearing/Bushing= http://www.partsamerica.com/ProductD...e=1219&PTSet=A

I need a new Throw-out bearing= http://www.partsamerica.com/ProductD...pe=239&PTSet=A


And this is ALL I need for the tranny to bolt up to the new engine correct?
And.. The Pilot Bearing/Bushing, Throw-put bearing. I looked up 86 z28 to get those... is that okay? or do they ALSO have to be pre 85? And am i going to need a puller for the pilot bearing?



-Andrew

 

forget about me? lol

I pulled the auto off of the new engine today.

 

No, just been out at the track.

Shouldn't be a problem with the year. Those parts didn't change, and going with the clutch year is a safe bet.

You don't need a pilot bearing puller, since there isn't anything in the crank now.

I'd rather go with a pilot bearing than bushing, but it should work either way.

 

Ok cool, thanks!

ok, yea so.. im trying to get this not to sound like im an a** hole. Text is tricky sometimes.

I am doing the swap this week.. so I need a definitive yes, or no answer.
Are the products I listed EVERYTHING I need to change out to make the engine compatible with my 5-speed?


If No, can you explain,
Again, sorry if i just sounded like an idiot.

-Andrew

 

Yep, just make sure you throw a clutch in there too

Everything else will bolt right up.

 

Well, is that necessary or do you just recommend that? cause my tranny and clutch only have 60,000 on them.

 

i wasnt saying you need to replace it, i just didnt see it in your list.

 

Are you pulling the old motor (one in the car now) and it's a stick/manual correct? Then just remove the flexplate from the new motor and install the old motors flywheel, busings, ect ect.... and your done. I would just buy a new clutch kit since your already taking the thing out, no time better than the present to change it. And ounce of prevention is worth about a $400 clutch job down the road

 

This is true, if it were me, i would replace the clutch while i was there. But you don't nessicarily have to.

 

Ok sweet
Thanks!


Yea I don't think im going to replace the clutch.. its in really good condition. But anyway.. Ill order these parts, and this weekend is the big swap.

The only thing im unaware of is where the pilot, and the throw-out bearings attach.


-Andrew

 

The pilot bearing goes into the back of the crank.

The throw-out bearing goes in the clutch fork, and slides on the front nose of the transmission.

 

K thanks guys for ALL of your help!!

Ill update on the weekend to tell you how it went!



-Andrew

 

I decided im going to do a clutch kit. So that just leaves the throw out bearing? should i just use my old one or should I really order one online and replace it.

 

Blah looks like I might have to the kit online. Blah.. o well
So.. what do you guys think about the throw-out bearing? order a new one online.. or just use old one?

 

i want to this tomorrow..
so plz help =D
THANKS!
-Andrew

 

might as well do it right the 1st time, instead of making it right the second time.... just get a new throw-out berring while your at it, that way you know it's all new and good to go.

 

Hey guys..
guess what!


ENGINE IS OUT!!!
I am going to replace all my clutch stuff with a clutch kit, change my brake lines, replace fuel lines.. and a little more..
so I will not be putting the new engine in soon.

But ill post again with an update when im putting my engine in.

Again.. thanks for all you guys's help.
