G'day folks,
Hi artxty, and welcome to the ODK Forums.
We do have a parts list for the Greenfield Tractor series available for download; it's the second file on the list
HERE.
However, I'm afraid that the OEM part number may not be much use these days, as these models ran out of factory parts support [as they were over 25 years old!] before Greenfield sold out to Cox Mowers.
But all is not lost; Greenfield used standard industrial type parts wherever possible. If it's just a standard radial ball bearing, it'll be readily available from industrial bearing suppliers [or even the likes of Repco, for common types] - you'll just need the type number from the side of the outer race, once you have the bearing out. This will be a 4 digit number, and add the suffix -2RS to spec the double side sealed version.
Some Greenfields used clutch shaft bearings with an extended inner race, to allow the use of set screws to lock it to the shaft. These are known as the 'set screw mounted' bearing type. Yes, they are available through bearing specialists. NSK make a range of them, among others.
And yes, it's a long job to get the shaft out and back in, so definitely replace both bearings.
On the wiring issue, the wiring harness on these old models was very simple indeed, and I've not even seen a wiring diagram for them. But with the aid of a few pics of the setup, it shouldn't be too hard to work out.
