variomatic replacement
Hello guys
The variomatic on my '84 340 has died and I need to change it. I've found a donor car, any tips concerning a variomatic swap?

hi there..... quick question....
picture
http://i35.photobucket.com/albums/d156/ ... 0/cvt2.jpg
is the secondary the bit labelled as so in the picture?
is the labelled nut on the secondary the one that can run loose? Should I check this on my CVT car? whats the problem here... the nut runs loose and damages the thread? is it not repairable?
are differential failures uncommon? due to low fluid in diff??
pulley surfaces... they rust and hence damages belts?
can they be sanded smooth again? painted??
cheers..
thanks for your info!
look forward to reply!!

all indication arrows correct.
no painting on the surfaces. if there is some rust at the places where the belt has sat over long periods of time, thats no worry.
remove any 'blisters' of chromium because these tend to break, and the edges are so sharp they cut up the belt. sand the edges of the rusty areas, so that all is smooth again. you can't do much more, honestly...
the nut often comes loose just a bit, so that the pulley can move a tiny bit under it. (it moves coaxially) due to that movement, the teething that supplies the transfer of power gets damaged. if this becomes severe the nut runs off and the pulley gets launched to the bottom of the car....

I'll check the nut on mine next time Im under the car... wait a while as its cold here at the moment!
When the pulley moves, if this nut is loose.... its moves from side to sides ie looking down at the gearbox through the floor but facing the boot ...the pulley would be moving left to right.....
So for the pulleys its just a case of sanding them smooth.....?
What are the pulleys made from? steel?
thanks for your advice!! very cool!!
enjoy your 340!

Im going to try to find the tightening torque for that secondary bolt.... dya know what its "techincal" name would be in a manual??
cheers

thanks for all your advice!! really useful!!
Dya know of any good CVT service manuals? Ive already got Haynes and Autodata... is the Volvo one the good in your experience?
Im trying to learn to service them from books really as they are quite uncommon and garages dont know what to do... are they easy to work on?
