PZ 2 piece flywheel

[crushers]

someone posted up a link to a repair for these.
i have not pulled this one apart yet but i would like to have the info handy just in case.

anyone have any info on these feel free to post here.

background:
ex-mine abused engine and flywheel.
installed into my 70 and further abused
installed into my 78 and further abused

now i have a vibration that comes on at about 80 k/h, if you hold constant then all is well. if you let off there is a lot of vibration. the t/case needs rebuilding, confirmed. but while i am in there i figured i would take a look at the flywheel. by all rights it should be buggered.

cheers

The two PZJ77s that I helped sort out involved welding the two parts of the flywheel together, having it balanced by a machine shop, then using 3B clutch and pressure plate.
MUCH better, no more weird thump at idle and springs and crap flying around in the bellhousing.
