@ Evodelta
great info. Should have known that quite long ago.
What did you do for the planetary gears?

@ #84#
so, you have an extra ? km for the top speed! And fuel economy in cruising speed!!!

Thanks to both of you for the info.

If the gears have got this bad then it is a bit too far really for repair, but if you wanted to you could and get a few more miles from it.

Basically you push the pins back into place and make the stakings better (the staking is done not very well by a special punch in the factory which puts the star shape on the outside of the crown wheel).

Some people weld them in place, this is 100% secure, but you have to be aware that any work you need to do another day will be difficult or impossible without destroying the parts to get them loose. Also, use TIG weld and immerse the component 90% in water so as to cut down on the chance of warping due to the heat (TIG is a cooler weld).

Take note of what I said earlier in that this problem happens less to these later transmissions, in the pictures are 1990 integrale 8v components.

ok Evodelta,

we always use TIG welding and I know what to do with this welder. As soon {hope later as possible} as I'll take apart the gearbox I'll go for the plate and the welding.

Thanks again.
