512 TR gearbox failure

Oowwwwwwwwwwwwwwww !

Gute Zeit um den ganze GB jetzt zu "renovieren"! Now is the time to refurbish the complete GB imo !

BB Motors in Stuhr (here also known as Cavalino.. ) is the only one I can recommend.

Slow but reliable and good. GB building is a real profession ! Get the forza Components diff now also.

And get the clutch refurbished ... all in once.

KEEP US POSTED ... as mentionned -> THIS will happen to all TR and 512TR gearboxes, it is only WHEN will it happen ...

Good Luck Markus.

 

hello markus
I´m still in thailand but at home I have all parts what you would need.
will be back 20th of april
just think over about a stronger diff then, only a little more work

 

There is a used one out of a write off car on e bay, from a seller in the UK but £18 000.

 

used one for this money? for this amount you can overwhaul the gearbox and know then what you have

 

markus, I told you that I will be back 20th april, but before end of mai I would have no time to start with your gearbox. too much work already until then. but if you or your mechanic need parts you could pick them up after the 20th april

but such a broken gear I never have seen

 

Can you elaborate why the gearbox's will break with time ? I know that the differential is one of the weakest links of these cars.

 

what your mechanic understand under:
broken gearboxes?
pictures?
description?
I never have seen gearboxes broken only without any other damage. always if gearboxes ( so the gearbox-case/housing ) are damaged it is a part of other failure in the gearbox

 

I must admit i throught it was a bit steep at 18 000, there are pics of the TR after the accident , front end all gone but back half ok

 

Markus, I was very sorry to hear this. I hope you can resolve it soon and be back on your favourite roads, without too much $$$$ and pain.

 

markus i feel for you man. sorry this happened....i am dreading the day it might befall me.

from what you say though, i would go the route of BB and rebuild the gearbox. use the stronger parts recommended as well. this way you will have a much stronger and reliable box that you actually have seen the inside of - more peace of mind.

 

I think you have now 2 splendid contacts; maybe Romano can help you on the broken parts, you order the diff and new clutchplate (Superformance) and ask Andree to rebuild ...

You are lucky we can tell you the way to go; I hadt to find it all out myself

But: it may cost you the full season (not driving I mean) ...

Consider: how to get it fixed: bring the car on a trailer or remove the GB yourself ...

Quite common. I used to have a box full of gears that looked just like that.

The gears are being made.

 

until now I only have seen gears with missing or broken teeth, but never gears broken in 3 parts. but good to learn

 

1st and 2nd drive gears are too thin. The distance between the major diameter of the internal spline and the root of the gear teeth does not provide enough strength.

In any event the gear pictured was bad from poor lubrication. A better oil and more frequent changes are in order when it goes back together. That is just plain poor service. Badly pitted and wearing off the hard facing? Bad show all around. I sure hope the ring gear looks better or this is going to be an expensive fix.

 

this pitting I also have seen often, but never so bad as here now. so bad or too old oil is one of the reasons, also may be to warm/hot oil during driving.

sad to see this at the beginning of the new season , but good markus, that you have an other F to enjoy also

 

If the oil does not prevent that when hot it is the wrong oil. It is not acceptable or normal.
