Describe force!? I wiggled that thing around a ton! And tried working it. I’ll be back at it though soon. But its raining pretty good today. I’ll pull it apart and recheck the alignment.

Thanks

Try taking a wrench and turning the engine pulley nut back and forth while pushing it in. Sometimes you have to lift it or lower it a little to get it to line up.
You are sure you got the disc in the right way right??? It should only go in one way since one side sticks out too far and would hit the flywheel.

As I said earlier.....a little never seize and a little grease on the very end for the pilot bearing.

Looking at your pic it looks as if you have not gotten the pilot shaft to fit in the pilot bearing. You don't want to use the bolts to force it in.

Pull the engine out and check the alignment once more with your spare shaft...make sure it's centered in the throwout bearing.

Jacking it up or down a bit and pushing while turning the fan with the transmission in neutral should make it find the hole.

I have had the same issue.....just sit back and grab a beer and think it over .

The new disk went in the same way the old one came out. There was maybe 1/4 inch or so that the bolts snugged the pressure plate up.

I’ll try rocking the engine tomorrow. We are in the middle of a storm and the Baja is not in the garage.

I’ll check all the alignments. The pilot shaft was all the way up to the edge of the splines.

Thanks again guys.

The reason I asked about looking at the flywheel is that when you have clutch slippage like you showed you can get some "bluing" on the flywheel which can mean hard sports.

The other thing is that when some machine shops "turn" a flywheel they forget to turn the upper side of the flywheel where the pressure plate (PP) is bolted to which, in turn, can reduce the amount of pressure the PP gives: there is a dimension for this which I can't find right now.

Back in the mid-90's I bought a almost new rebuilt engine from a friend of my "late" stepson which turned out to be a disaster in so many ways: it was supposed to be bigger than stock (cubic inch wise) which it wasn't and all the machine work was bogus including the turned flywheel being not machined right.

Lee,

Didn’t see any bluing on the pressure plate or anything super out of the ordinary.

Though full disclosure this is my first car clutch ever.

I’m not gonna machine this one if needed I’ll look at other options.

I think you said the clutch disc slipping was on the flywheel side which is the most common place to see it. That it why the machining of the flywheel is usually done on an engine rebuild or checked for "runout" to get things back in shape for the clutch change. People often by the disc and the PP as a matched set... but not always. I learned a long time ago that the flywheel is a problem area when you get a used car. Too many people, especially now days because "stick" cars are not that common, so they probably didn't learn how to engage the clutch properly.

Those of us who live in hilly area have to learn how to engage the clutch, especially when a stop light is on a hill, or go broke changing clutches. My ex-wife burned out the clutch on a brand new '67 mustang fastback with a 335 hp 390 and four-speed during the short period I was in the hospital for my first cornea transplant. She then destroyed a second one and warped the flywheel during the 30 day period of my recovery before I could drive and go back to work.

Turbo/EFI Baja

Post by Schweg »

Got the clutch and engine back together and everything mated up!

Once I had the engine in I decided it was time to throw on the Intercooler I had laying around.

Image

It’s mounted to the engine vent fins and also where the trunk hinges attach.

Took it in this morning and blew off the turbo side coupler. Thought I had completely broken it as I couldn’t make boost after that.

All said though the clutch felt like it held good.

Leaving work I tightened the coupler clamp and took off. Ran a log that I need to check out in a bit, but just off intake air temps the highest I saw was 82. Ambient air temp was 72 so even at 19 psi I was only seeing a 10 degree rise.

Image

As shown above I moved my W/M jet up stream to try and cool the charge more before the IAT sensor.

Still need to adjust the clutch as it grabs a bit low. And I need to look at tuning the boost duty table but all in all I’m happy to be driving it again!


Thanks again for all the help!!

An intercooler that big will help a lot on your IAT


Drive it like you stole it'!

Yeah, just pulled the logs and at max boost I hit ambient temp. After i let off I went sub ambient by over 10 degrees.

This thing is fun I plan to just drive and enjoy!!
