The fan attaches to it's mount using a rubber/nylon spacer, vibration damper. 3B8676. I have ten for sale. I once ruined a good Diesel 40 radiator to a failed 3B8676. I believe they fit many machines. PM me.
I was just informed they fit (two each) diesel 40 and RD6 and it looks like they fit my early D6. Could somebody PM me and suggest a fair price for these as I can not find any for sale let alone for what price.
