So the throwout bearing on my 92 SHO is bad and I need to replace the clutch. How difficult is this job and is there any videos or writeups on it? I am probably looking at springtime next year for the job as its getting to cold now here in PA to be laying under a car to work on it.

Shonut made a cd, you would need to see if they are still available. If you search on this forum, I recall seeing some written instructions, but no pictures

There are write ups here on the forum and a very good guide in the SHOPhoenix page.

I'm getting older and don't have a lift. Doing a clutch is a weekend job for me now. Without any snags coming up, my goal for day one is to get the trans out, clutch swapped, trans back in, and subframe back up. At that point I can remove the engine support and close the hood for the night if it's getting late. Usually the next day or the following weekend I'll button up everything else and take it for a drive. It can be done in one day if everything goes smoothly and can be done in an afternoon if you have help.

My best advice for this job is to take an old subframe bolt and grind off the head of it. Use this as an alignment pin for reinstalling the trans. Makes the job 100% times easier if you are doing the job by yourself. I use the far right hole in the engine and once the trans is on the bolt/pin you can easily get it lined up and on the dowels.

Great advice in both posts. I would recommend the shonut video. Go to the home page and then look for clutch parts. The dvd is on that page under misc. parts.

I seen some where people making a jig type of setup to brace the engine from above with the cars body. Anyone know the dimension’s of said thing? I work a concrete plant, but our shop is stocked with a lot of tubular and square stock steel. I can weld something together if I had an idea what it looked like.

Also where does one attack it from the top? I can see the eyelet on the front, but where in the back?

How big is that subframe bolt? I don’t exactly have a spare one on hand, but I got plenty of round stock steel rods I can cut and shape as one.

send Josh T an email or message through the forum.


There used to be archived engine braces on the forum. Hopefully they are still on here.

There are links in this post to earlier posts but those will not open for me. Maybe an admin can access? I think I recall sdpatt made one and posted its dimensions. If you get desperate enough you can try and send him a message through the forum.

This should work https://shoforum.com/threads/engine-support-details.9138/
if not it is a sticky in the "how to" section near the bottom keyword support

On the Shonut website, the clutch video page had a link from Nick on how to build the engine brace

Hey thanks that link has the specs for building the brace, but no pictures. I think I’ll try and message him to see if he still has pictures. Would be really helpful to see it done as well as build it too

Wiki SHO is your friend....
hey thanks for the info! I didn't realize you could buy a engine brace for this application, so I am going to do that. In anycase thanks for the help. You think it is wise to just replace the flywheel over getting it resurfaced? from what history I have on this vehicle I recall the clutch being replaced once already at about 75k miles.

Flywheel thickness is 1.186" new. Minimum thickness 1.141".
When the flywheel is resurfaced on a Blanchard grinder, it takes around 12 thou of. So it can be resurfaced 4 times before it gets too thin. If that has only happened once, you shouldn't need to replace it.
