My first post, long time lurker so I want to say hi. I picked this 212 up last August and have restored a lot of it, didn't mess with the driveline too much other than the belts but did replace the piston,rod and crank bearings. The transaxle seems to be in decent shape, only thing is it will whine a little with the variator in the forward position and it's not so much a gear whine but a bearing noise.....probably the input shaft.
I understand the straight-cut gears have an inherent whine but this is different. I do notice 3rd gear makes the most noise but neither gear is unbearable. I did replace the secondary idler pulley and that helped, as well as the gear oil and have 85-140 in there now.......what I drained was chocolate milk-like but not water.
I'm contemplating just opening it up and going over it, maybe replace the 3rd gear sprockets as well as other common wear items.
I did read the recent thread on the 212/peerless 2300 and that helped as well as other threads. Looks like this will come out fairly easily so any pointers for a first-time rebuild is greatly appreciate. I'm fairly mechanically inclined and I do want to do this right if I set off on the journey.
