Duraline on mmc disk backs?

Recommended Posts

Hi,

 

as per title. Just putting this back together, do I need to put duraline on the back of the disks where they touch the drive flanges?

 

there seems to be evidence of some there previously but the mating face of the disk looks like it might be steel...

 

thanks,

You can do but a very thin smeer , in reality the galvanic corrosion of the 2 materials isn’t that much of a problem unlike stainless and copper , as the Mmc disks have some aluminium in them you do get some corrosion but by the time you have worn them out that won’t be a problem as you can’t replace them and they won’t hurt the drive flanges anyway , as the disks will be the sacrificial anode as it wer , hope this helps

No sign of duralac (or copper-ease etc) according to Lotus; they do insist the mating surfaces need to be "scrupulously clean" 😷 time to get the marigolds on...
