I'm replacing the clutch on my 87 trans am tpi 5 speed all stock, and I was wanting to know what other parts I should replace with the clutch like plates, bushings, ect. stuff like that. Also what the cost of those parts would cost apx. This is my first clutch replacement job, so any info on taking the transmission off too, would be helpful. Thanks

 

The flywheel would probably be a smart thing to replace. Because the clutch, when it engages, contacts the flywheel with it's friction plates. I am converting my automatic to 5 speed from an 87 as well. This is what I am getting:

Typically you'd just resurface your flywheel if you want. That's a cheap machining job ($40?). A flywheel doesn't really "wear out", so unless you want to replace it with an aftermarket one, don't bother ($250 for a new aftermarket one perhaps?)

Normally you'd buy a clutch kit, which includes friction disc, and spring plate (forget it's technical name now), alignment tool, bolts, TO bearing, etc. ($150?)

You can replace your tranny mount ($10 stock, $20 aftermarket) if you like, it's easy to do while the tranny is out. If your u-joints look bad, you can do those too ($15 each x 2).

The tranny is a bit heavy when you're under the car (bench press while moving it). I'd get a helper to remove it, landing on your rib-cage is less than desirable (*cough*)...

 

Hey Wabbit,

Sorry for piggy backing on your post. I'm planning on doing my clutch as well. Got a Zoom HP kit from Summit for about $280. But I was also wondering from the others would it be wise to also change out the master and slave clutch cylinders as well? Also, how hard is it really to do the job by yourself? A weekend. Lastly I heard rather that taking the flywheel to get it resurfaced you can just use a good orbital sander with 36-60 grit and do small circles to clean it up and take off the glaze?

 

I am going to be helping him. I talked him into the Trans Am, so I figure I gotta show him some things...I haven't done a clutch either though. Any tips would help.

 

A new flywheel is 100 bucks, I would recommend doing it right the first time so you don't have to replace it before your clutch...

 

I have a clutch kit, I was just wondering what else I should buy thanks for the help.

 

There is no reason to buy a new flywheel unless you have chipped teeth on the outside or something. A machine shop will charge you $40-50 to resurface it, and it's good as new.

--BTW, a "new" flywheel for $100 at Checker is an exchanged core that has been resurfaced

Just resurface yours at a machine shop for less money.

I wouldn't say a new pressure plate is necessary, but it's a good idea. Definitely get a new throwout bearing and pilot bushing/bearing. Get a clutch alignment tool if the kit doesn't come with it. Use plenty of grease on the TO bearing and input shaft, but keep it off the clutch disk. New hardware is never a bad idea, and be sure to use loctite on the bolts.

I see no reason to replace the clutch master cylinder, however the slave cylinder is plastic and prone to cracking in my experience... If your slave cylinder is cracked, I would replace it with an aluminum one ($50 give or take)

 

I second the resurfacing tip. If you don't want to replace the flywheel, you've got to resurface. Had an 86 v6 about 15 years ago, and my uncle said nothing needed to be done with the flywheel. Well, it warped on my and I'd hop down the road when taking off. I also blew out my first gear which made everything worse. Not a fun ride. With my 92 rs, I'm taking those mistakes and going the right way this time.
