    The gear box is completely apart now and a few parts need replacing plus bearings. The parts are so expensive from Ferrari and other sources, I just don't see why they can't be manufactured (copied) by a company like Emco, as they originally made the drop gears for my spare box that also burned up. The drop gear box was used when it raced in the Challenge series. http://www.emcogears.com/.

    1-Where do you get your parts? Sometimes Ricambi is better priced on some things, other sources are less on other items. I do like Ricambi and Daniel Pass-he is the best friend a 348 brother could have, but price is an important issue. Does death by a thousand cuts help explain the history of my Ferrari Repair Experience? So what if I've driven it around the earth twice with multiple track days in addition to it's Ferrari Challenge racing history....

    2-Anyone had any gears or parts manufactured? Don't they have the technology to scan these parts and have them computerized machined?

    3-How many hours should it take to rebuild the gear box? I have been told it is a very difficult box to rebuild.

    The car is really being totally freshened on all corners, engine out detail and clean up getting ready for Road America and the FCA National meet this year www.fca2009.org. FOW did the belts not so long ago, and I am now having to redo them due to leaking cam seals, etc. I should not be doing this at this time, plus a once bright friend 'fixed" the box for 5K replacing some bearings in the process, and less than 5,000 miles same problem-it was jumping out of 4th gear. The kicker was the rigid oil like that was nearly chaffed through from being place in the wrong position as it rubbed on the frame. Seconds from disaster...

    Some of the bearings can be made to work quite well on the cheap: http://www.ferrarichat.com/forum/showpost.php?p=136946088&postcount=104

    I got the BA2B 636151A's from SKF in the UK - total of USD 100 for both. If I finish my spare box rebuild without using them, I will have a spare set to confirm in 2 weeks...

    Acorn Industrials (+441709789999), ask for a lady called Lynn. The Original Ferrari bearings were part number BA2B633912 with a C3 designation (hardness and precision) - these have been replaced by BA2B636151A also with C3. The dimensions are : outer race 76mm ø, inner race 35 mm ø and bearing width is 28mm - I don't remember the thrust angle, but I do remember it matches the original (don't know why 43.5 degrees rings a bell). I got them for about GBP 34 + VAT and shipping and they got delivered in 3 days.

    Look at your bearing part numbers etched on the side. It would be interesting to see if these were original bearings that failed or ones that had been replaced...

    Juan,

    The rebuilt box blew? Where did it go bad? So far no grenades here. I've done less than 10 more than 5. Timeframe?...takes a day of goofing around and its done. It depends if any of the brotherhood come come visit and heckle me. Even Ernie's box is still together and you know how his stuff blows up all the time. FWIW the Reiner bearing is still going strong and Reiner is not a gentle driver.

    Thanks to all of you guys, and I am sure more post will follow. It really is good to be part of a "Brotherhood". I'm not sure why the gearbox failed again in the same gear (kicking out of fourth), or exactly what parts the former person replaced, but I'll know soon. I saw the parts on the table this past week. Lots of wear, noise as they spun, etc. I'll talk to the shop and see if I can get them to post some pictures of what is bad, and what is needed. One piece they said had 13 micro cracks, so that needs replacing for sure.

    The shop it is at now has a Alfa Romeo TIPO 33 on the bench, and they are known for their precision machine work. GTM formerly of Belgium-Guy Trigaux, now in Simpsonville, SC. FBB, if I lived in your area, as much as I've been through on the gear box, we'd be good friends by now. Glad to know that it can be done in a day.

    Glad you caught the problem before losing the line, Juan! Neat Pantera.... I always wanted to have one, but prices are too much for a nice one now, compared with other options. Still, a poor man's GT40!

    OH MAN!!!

    That is the main oil line going to the engine from the oil tank. It's a good thing that line didn't blow, cause you would have had one NASTY mess and possibly an oil fire.

    Hi Juan, after looking at your pics, it looks to me like one of your mechanics removed your subframe crossbraces, and reinstalled them backwards. Your front crossbrace that has the bolt that rubbed against your oil line should be mounted at the rear of the subframe, below the gearbox. And the one you probably have installed at the rear goes on the front of the subframe.

    See pic of mine attached... you can see my crossbrace has a stud next to the rear of the gearbox, and can see how far it is from the solid oil line. These studs on the crossbrace are to mount the parking brake line that runs across the rear of the subframe, under the gearbox. Also, the front crossbrace should have stud(s) on the driver's side to mount the bottom shield that protects the gearbox cable shift mechanism. Mine's a '92, so there could be some minor differences in how these cars were setup, but I'd recommend checking this out! :)

    Jeezzeess...I'll have them check it out. I thought that maybe they left off a loop for the line or something. Who else agrees with this? Can you imagine someone putting this on the wrong side...?

    IIRC FandLcars is correct...nothing escapes the brotherhood.

    The last rebuild I did on the gearbox, I sourced the upgraded parts from a 355, so I am hoping that the strengthened parts will be bullet proof. It has been 4 years now and no problems. I used GT car parts in PHX for the 355 bits.

    Juan, that sounds really good of those stupidly expensive gears could be done at reasonable price. Pls keep us posted! :)

    US $100 is a great price for 2x bearings. :):)

    I called my mate at our local SKF and was quoted AU $139 each and the bearings had to come from France! :eek::eek:

    AU $278 or US $195 for them. :(:(

    Does that SKF shop in the UK have their own website so I can get some bearings from them? :D:D
