Getting things carried out by others is my Nemesis! :(
Ok this is a strange one. I separated the gearbox from the prop and both gearbox and prop spin as they should, forward and reverse, although I would say the reverse on the gearbox is quite stiff (not sure if that's normal). Then I re-connect the two and again both spin in reverse until the very last tightening of the nuts, then the wheels won't budge in reverse. Just loosen the nuts very slightly and the wheels spin again. All works fine going forward at all times! Ive missed the gearbox person now and just wondered if anyone had any ideas?
I believe you are "binding" the prop shaft either too long or too short, there are slip couplings on both ends of the shaft and there is a specification on a certain amount of play the shaft needs to "float" in place. So if it is short, as you bolt together, the trans mounting bolts draw the shaft forward and it locks up, if the shaft is too long, same problem, only you are "pushing" the shaft to the rear. Loosen the front or rear coupling enough to allow the prop shaft to collapse or expand as needed, and make sure there is an amount of endplay to allow the shaft to move a bit as things get warm and expand before you tighten the slip couplings. Hope I can help. Gary
Hi Gary, yes exactly that. I managed to fathom it out by releasing the rear coupling, bolted up the gearbox / prop flange plate and ensuring there was movement in the wheels and then tightening the rear coupling again. What threw me was the forward travel was unaffected. Turning the wheels in reverse is still stiffer than forward but this was the same on the gearbox when it was released. Thanks for your input and confirming the issue. I'll also take your tip to release again and let things move when warm.
She's back in! All quite straightforward, the trickiest issue trying to thread the gearbox dipstick tube down through at the same time...another stupid design Image Unavailable, Please Login
Programme of works is now disrupted! I forgot the airboxes go on before the carbs and I hadn't gotten around to refurbing those in the meantime! Now, satin or wrinkle finish?? I noticed when I starting stripping them there was evidence of black smooth paint under the wrinkle....hmmmmm, the plot thickens!
Ignore my previous comment about the airboxes going on before the carbs...I think the paint stripper fumes had got to me! Anyway, all ready for preparation. Im torn between wrinkle and satin. Anyone want to offer some opinions before I commit? Image Unavailable, Please Login
Mine are a soft wrinkle if that makes sense. they do look good. Great thread and a good benchmark for my restoration.
I have an original brochure from 1976 when the 400GT first was launched. I'm pretty sure that car is pictured with wrinkle finish airboxes. I can double check
Definitely at least some 400s were satin black originally, possibly some were wrinkle finish. Probably most 365GT4 were wrinkle, probably some were satin. They are the same part number but on 365s, the number is stamped, on 400s the number and "FERRARI" is pressed into the body. (Euro spec. 365GTC4 were satin, U.S. spec. were wrinkle - different part numbers and construction.) Regards WM
Well I went for a compromise in the end....wrinkle on the outside, satin inside! Thanks for the tips chaps. I used the same wrinkle paint as used for the cam covers and air ducts. Pleased with results. Just waiting for the seals and I have to plate the clips. Image Unavailable, Please Login
Taking shape now. Just waiting for some silicone hoses, which although Im not a great fan of aesthetically, but in typical Ferrari fashion, the top connection between block and radiator has to change in diameter quite significantly which puts quite a strain on the rubber hoses.

Looks GREAT............................................................................................................. pity about the dipstick on the middle left of the pic though
What do you mean.... Am I missing something?? Still waiting for the silicone hoses! Also wasn't happy with the wrinkle on one of the air boxes so stripped it again and repainted. That was after I decided to install it with the trumpets, filters etc......another 4 hours of my life taken up
You,unfortunately,only have two pedals with which to operate your iconic carburettored powered Ferrari!
Yeah,Yeah,yeah,spoke to Marc last week.....it's getting there. BTW can you crank up junior for me some time...
Where are you getting your silicone hose from. I'm just waiting for a quote to have them produced and wrapped in 'classic style fabric' as to avoid the shiny finish of silicone.
At my local 'hose' shop, where I had my braided gearbox lines made up. They're in place now and actually don't look too bad, however that pesky joint between the water pump and timing cover is weeping...had to be that one didn't it!
