Got a Kawasaki 2510, 3010, 4010 Mule with a blown up diesel engine? Need replacement 950D Diesel engine?

The Kawasaki 3010 Diesel Mule came with the infamous poor Daihatsu 950D engine.
which suffers from poor crankshaft and rod design, along with diesel head overheating problems.

Untill now you had to either do expensive repairs to the Kawasaki 2510. 3010, 4010 Diesel Mule engine or purcahase a new Kawasaki 3010 Diesel engine at cost of over 6000$, or try to find a used one only to have the same problems again!

We have developed a kit to install 16hp-23hp Briggs and Stratton Vanguard gasoline engine into your Kawasaki 3010, 2510 and 4010 Diesel 950D Mule.

The Kawasaki Mule 3010 units came with either a 20hp Kawasaki engine or a three cylinder Daihatsu 950D Diesel engine, both these engines were installed in the same basic machine. The gasoline Mule 3010's engine versions been very durable while the 950D series Diesel has proved to be very trouble prone.

Our kit allows you to install a Briggs and Statton Vanguard gasoline 16-23hp engine, these engines will power the 2510, 3010, 4010 Diesel Mule well, with the 23 horsepower units actually performing better then the original Kawasaki Mules.

Some features of our Kawasaki 2510, 3010, 4010 Mule diesel engine conversion kit:

1) Maintaines the original enclosed air cooled clutch belt drive system.
2) Keeps the stock engine height, which means the bed still shuts correctly.
3) Removes the entire water cooling system, with both radiators removed.
4) Provides Briggs and Stratton durability, low cost, great parts support.
5) Uses most stock components to lower conversion cost, including the enclosed clutch.
6) Mule is MUCH quieter with Vanguard than rattling diesel.
7 ) Allows you to use your Kawasaki KAF950 Diesel Mule again.

What owners are saying!

I would just like to Thank you guys at Route 66 parts, the diesel to gas conversion kit I purchased for a 3010 mule worked fantastic! The lady I did it for was very excited to have her Mule back in service after 10 years of setting in her barn. It was very cost effective way to get a machine in great condition back to work. Thanks again guys!

Brad Holthaus.
