We did one a couple of years ago. Bought them locally. The disk had been used for a while with a broken disk bearing and the disk actually cut into the shaft. We disassembled everything (thank God for air tools) and then welded several long lines on the shaft and ground it down until the new disks fit correctly.

I wish they made disks with grease fittings. But that would make them last forever and they wouldn't sell as many...


I love my country, but don't trust my government.
