In this video I repower my Gravely Model LI with a Yanmar clone 10HP diesel  engine. This engine was fished out of an enclosed style Aurora generator.

For this repower you will need:
Gravely Model L
Yanmar L100 or clone
Tapered shaft adapter
7-1/2X1/4x1/4 steel ring
2X Volkswagen Mk1 brake rotors
M10x1.25x90 grade 8 bolt.
Misc hardware and steel
Access to a welder and lathe
