    New Throw-out (Release) Bearing, Mounting the Bell/Transfer Assembly w/ new O-Rings, Installed Clutch Cylinder, and Spark Plug Wire Set
    • The supplied clutch kit included a new throw-out (release) bearing. The original cast bushing is pressed out of the original bearing, cleaned and pressed in the back of the new bearing. A very light coat of moly based grease is applied to the sliding contact surfaces.
    • The drive shaft is inserted through the bore engaging the splines. Fresh O-rings are mounted, and the bell/transfer assembly is mounted to the back of the engine.
    • The clutch cylinder is mounted, and then bled.
    • The Cavis Spark plug set was re-mounted after being inspected for cuts and or abrasion.

    Finishing the Project :)
    Headers, exhaust fuel, oil and cooling tubes/hoses, heat shields, fuel distributors are all now installed. Fluids filled. Cooling system bled. Started the engine today checking for leaks. The engine sounds great. There was a fuel fitting on the left bank warm up regulator weeping, so I'm checking it out as this image was taken which is why the plug wire and air filter housing is off. To get to this regulator is a real beast. Flex Armstrong would come in handy here.
    • Just to set the record straight, I miss quoted a tread reference on post# 80. The tread was by Ago Car Nut not Turbo-Joe. Sorry about that.
    We just had snow last week so there is salt still on the streets. We will need a good Spring rain before I take it out for a test drive.

    Dave, I just read this whole thread and I tip my hat to you for a thorough and well documented engine out service. Not something I would attempt and admire those, like you, that can and do. There is so much intricate knowledge and even with the WSMs it takes some interpretation and technique. If you don't mind my asking, where did you learn how to do this type of mechanical service?

    Well thank you!
    My father was a retired Army Aviator and Transportation Officer and my Grandfather was a retired Machinist. Both were hands on, and fantastic mentors during my youth. They passed on their talents, patience, and determination to see projects through.

    Hey Dave..

    Great article. I own 51723 and am getting ready to an engine out but will have it done, I'm not as brave as you!

    Car runs great but the AC compressor seal is gone, and the low oil pressure light sender is leaking so it's a good time to take care of these things.

    A couple of things, the last time I had an engine out I used Evans Cool for coolant with great results, no overheating even here in sunny and hot Florida. And more importantly no electrolysis either. Just FYI.

    Re the MSD, I'm on my second one. My Marelli went out years ago with ZERO warning. One morning it worked, that afternoon it didn't! FYI, should you experience this, Dick Fritz said to remove the Rev Limiter and that might fix it. I wish I had known! And to add to what someone else said, I do think MSD quality is on the decline.

    Anyway, great article and keep the info coming!
