Yes, the 2-arm 8N governor can be retrofitted onto a 9N or 2N tractor that used the 3-arm governor. Here is a LINK, to a recent post about that, or scroll down this forum list and see it as it is still fresh. The original 9N governor had 3-arms, no oil lube inlet port -that was added later. It was deemed that it required additional lube so Ford engineers added an extra oil line to accommodate. We have a scan of the original Governor Service Manual in our MANUALS forum for FREE download too. When a farmer brought his tractor in to the dealer for service, it was advised to add the oil line if his was a prior governor without one. Hope this helps answer your questions...
