    I am contemplating replacing the rear main seal in my 2003 F 360 spider and would like any advice and or pitfalls to doing the job myself. This is three pedal gated 6 speed with 37,000 mile. I have a lot of experience working on cars - restored / repaired multiple cars over the years.

    I am contemplating installing a kevlar clutch with a light weight fly wheel while the car is apart. I have been reading about a Hi Tech does anyone have experience with them or another suggestion?

    I am amazed there is no YouTube video of this process!

    Question:
    Does the trans axle slip between the upper frame and lower frame in the rear of the car?
    Or out from the top or Bottom?​

    I saw mine apart at the Ferrari workshop and the trans only had to be moved back a few inches to get at the clutch. Trans doesn't have to come "out" so to speak.

    usually comes out in between. you move the gearbox rearward, that it.
    light weight flywheel----- worth it, but not much. kevlar----no experience, but i'd assume its the same. i don't recommend to replace it with kevlar for longevity purposes because your throw out bearing seals would go first, in which case you'd have to remove the gearbox.
    if you are doing Kevlar for money saving purposes, that's another story.

    Kevlar is a very good option for a clutch plate.

    It handles high temps much better.

    It is not less costly than standard;it is actually slightly more expensive.

    Hi Tech want 5K for clutch and pressure plate plus another 1K for the flywheel - seem a little high compared to a stock one at 2500
    Any knowledge about the actual job of removing the transaxle from a spider?

    That's a very high cost.

    There is a clutch rebuilder in SoCal.

    I will find the info

    Removing transaxle is a lot of wrenching

    take your time. Don't do it all at one time. Keep track of all the bolts and screws

    thanks for the advice -
    have nice heated garage setup for this winter project- will take lots of pictures
    do you need to mate the half shafts in the same position ? I will mark them before removing the bolts.

    use plenty of blue painters tape around the rear panels before removing the challenge grille

    prevents scratches

    Good Call on the tape- do you know if the rear hood needs to be removed?

    I'll be doing a clutch job in the near future. Please update us with any tips or pointers you come across. From my understanding the kevlar clutches work well on gated but not on F1.

    My car at 20K, bought it at 19K, had the rear slave cylinder leaking on the clutch...gated 3 pedal, so I would think of replacing the throw out bearing, slave and all while in there. Just my 2 cent...er $3000...experience. HTH.

    slave cylinder and throw out bearing are the same thing on 360 stick.
    3000 dollars isn't much if it includes parts

    The gearbox does not come straight back and out. It goes back, tilt down at the back to clear the cross member, and then out. You'll figure it out. You need to gearbox to be out of the way if you are going to change the rear main seal. Good luck, it is big job.

    Ok don’t know why I’m sharing this because I’m sure someone will undoubtably be negative about it.

    I’ve been pondering what I would do if my seal on the TOB was leaking but the clutch was still good. This is what I would do before dealing with a “correct” repair costing thousands and a bunch of my time.

    Thinking like a medical interventionalist, there is no way to snake a catheter up to the TOB, and there is nothing to put in there to stop the leak. So I thought of this:

    1- suck out all the brake fluid from the master reservoir.

    2- fill with this:

    Bar's Leaks 1350 Clutch Fluid with Stop Leak - 8 oz. https://www.amazon.com/dp/B07MSSZ358/ref=cm_sw_r_cp_api_i_NUwXDbSVBN2CV

    3- possibly add a fluorescent dye comparable with brake fluid to aid in determination of the next step.

    4- bleed the clutch system until I’m sure the new fluid is in the clutch. system.

    5- vacuum out the new fluid from the master to limit possible cross contamination of the brake hydraulic system withe the stuff that will swell the seals. And fill master with my usual brake fluid.

    7- bleed some of the new fluid through the clutch to wash out just a little of the stop leak fluid from the master and upstream clutch hydraulic system.

    6- now the clutch lines will have the new fluid and brake likes will perhaps only have a minuscule amount that will be diluted by the normal fluid.

    7- drive for a while and see what happens. Will take a while to get into the TOB and make a difference.

    If it fails I’m no worse off, as I was just going to replace everything anyway.

    Only risk I see is contamination of the brake system and master with the fluid that may swell the seals. But if the stop leak fluid is removed from the master I think that risk would be mitigated. I’d be willing to take that risk.

    I was planning on replacing the throw out bearing with a Hill engineering one.
    Thanks for the Yelcab for the info on how to remove the gearbox -

    that is an interesting way of looking at it! I appreciate the post.
    I am pretty sure its the rear seal the oil on the ground and in the belly pan is motor oil not hydraulic fluid.
    it does seem crazy to pull the car apart when the clutch is still good.

    in a 360, if your RMS leaks, it will sit there and leaks without the engine running at all.

    That is interesting - are you saying if I park the car and there is no oil after the initial leak its something else?
    I would still have to pull the car apart if its the slave!

    Rear main seal leak would be very slow with the car not running, and may be hard to differentiate from residual oil/hydraulic fluid. If not sure I’d add a fluorescent dye to the oil. Then check what leaks out.

    May be academic if you are going to take it apart you might as well do clutch , TOB, and rear main as long as you are in there.
