This product is a rebuilt Yamaha OEM complete 3B4/1HP servo assembly. Both part numbers are the same. See note below. If you are looking for just the servo motor to rebuild yours, click here. http://www.501parts.com/product-category/yamaha-servo-motors/
The complete servo assembly as shown in the picture is what you will receive, the small motor is shown for reference. Rebuilt means these assemblies have been inspected, cleaned, tested and rebuilt with a new servo motor (the small motor you see pictured). These are Yamaha factory OEM plug and play servo assemblies. They have been timed to 2wd and are ready to install on your front differential.
Includes O-Ring for installing on front diff.
Note: The 3B4-4616A-02-00 and 1HP-4616A-00-00 part number servos are the exact same. Yamaha updated the part number in 2012 but the part is still the same.
We offer a 1 year warranty our rebuilt OEM servos.
This product as well as most all our parts will also work with the Yamaha Clone side by side and ATV’s to include Massimo, Hisun, Benneche, Coleman, and Big Muddy.
