Kawasaki Engine FH500V-AS18-M.Electric Starter. Shaft 1" diameter w/extras 
This is 17 hp engine1" x 3.11" Shaft
Needs muffler and the exhaust manifold.

This engine has originally been used on a propane buffer. It is therefore converted to propane. It has a propane carburetor and no gas tank. It is however quite easy to convert it back to gasoline by replacing existing carburetor with a standard gas carburetor. As it is seen on listing photos, there are some extras that are part of this listing. I didn't bother to remove them so they may come useful. But the engine will work without these extras.

All engines I list and sell here on eBay are is working order. They were removed from perfectly working floor buffers because it is easier for me to ship just an engine, than a complete buffer machine that requires freight. They are however used engines, therefore they may need some attention, some parts perhaps, etc, depending on what is the purpose. I don't have any record of the usage. I also have lots of parts, mufflers, manifolds etc. If you need something, just let me know.
Engine oil has been drained.

I have retired from the floor cleaning business and have many good automatic scrubbers and buffers for sale.  All this equipment was working fine till the last days of service, therefore, if you are lucky, you may have a chance to buy relatively good products for a fraction of their market value. I will be gradually adding new listings, featuring floor cleaning equipment, spare parts, cleaning supplies, etc. therefore I encourage you to check my eBay Site from time to time.
