Transmission Removal / Install

[chris76114]

After my transmission went out I decided to remove it all. From the rear main seal to the input shaft. Had my transmission rebuilt by Standard Gear & Transmission of Fort Worth. I got a used flywheel from the All Z Car Specialist of Fort Worth. Standard also resurfaced the flywheel.

 

I used a harmonic balancer pulley to take off the flywheel. That way I didn't have to take off the oil pan and wedge a block of wood in the crank to keep the flywheel from spinning.

 

I used a 5 in 1 tool to take off the rear main seal. No damage. I used a small 2x4 and hammer to install the seal very carefully. Make sure you lube the seal, crank, and block so the seal goes in smoothly and easily.

 

Here's some pics. Message me if you have any questions.

If anyone is thinking of using the Summit Racing flywheel part number FW - 151 on a 1981 - 1983 280zx Coupe ( 2 seater ) don't bother. They sent me 5 of them and everyone of them was a 9 bolt setup for a 9 bolt pressure plate / clutch. The Coupes use a 6 bolt. Summit Racing isn't a waste of time, but they will lie saying they put their hands on it and counted. Heads up for all who want to save money. It won't work.

As for the Pilot Bushing inside the back of the crank I'm using a slide hammer and pilot bushing removal tool from oriellys.

On the pulled you will have to knock out 1 pin and insert a nail, screw, etc. I had to do this because the rental tool 67033 from Oriellys won't go in due to the ends are too big. You could shave some off, but I didn't want to damage their tool. Insert the still connected end in first then put in the piece that you have to take off. Then put connect it all like I did with something like a screw. Just as long as it fits. Where there's a will there's a way. Hope this helps someone that gets stumped. I happen to be handy.....sometimes.

Pilot Bushing on rear of crankshaft

Use a 14mm socket and be careful not to damage the bushing. This is where the input shaft from the transmission goes into the crank. You can use other sockets, but This is what I found to be almost exactly the same diameter as the bushing.

Make sure to tap the new bushing in to a depth of 4mm (0.157 in. ) I've attached a pic of What is in the manual by Clymer.

Best 280zx Shop Manual by Clymer

I figured I'd ad this because out of all of the manuals I habe this has the most information. If you can find one grab it. I got this one off eBay.

If you can't find information message me with what you need and I'll see if I have it.

Nice writeup.  The 225mm flywheels are hard to come by.  There's another trick people use where they pack the area behind the pilot bushing with grease then stick a dowel in the hole and hit it with a hammer.  Hydraulic pressure forces the bushing out.

The Factory Service Manual is pretty good.  Did you not like it?

And you posted in "CAR TALK > 510 cars" for some reason.  This is a 1983 280ZX right?  Maybe Mike will move it for you.  @Mike

I was gonna try the grease trick, but I didn't have any grease on hand. I just found out about the z car forums and still figuring things out. Thanks for letting me know where I was posting. I didn't know o was posting in 510 and not 280zx. I'll be be sure to post in the proper section because I'd like to help people out that need some knowledge. As far as the manuals go the Clymer has been the most informative and helpful in all aspects. Thanks for the message as well. As goes for all if you need anything let me know. Have a good day.

The more writeups the better.  There are many different ways to get the same job done and reading about them helps understand the basic principles behind the work.  You can break a pilot bushing in to pieces with a chisel to get it out also, for instance.  I had to do that once, when my new pilot bushing was too big to insert fully.

You might add a few details about you and the car just so people know who the heck the new guy with the 280ZX is.  That flywheel looks like it's been sitting for a while.

[chris76114]

Now that's new one for me. I can see a chisel doing it too. Where do I go for the details about myself and my cars. I also have a 1983 280zx Coupe turbo ( automatic) that I will be doing a full rebuild on. I've had z cars for 15 years and i'm still learning stuff. I'd like to get those details in as well. I don't do facebook or any of the media things so this is pretty much my only contact to the outside world. Id rather talk to z car people anyways, .
