    QUESTIONS & ANSWERS

    Ask a Question
    • How much does this stretch? My joystick base is 3"x2.5" and 4" tall with a 7/16" joystick diameter.

      Greetings! There is some flexibility. Given the information provided, we believe the boot would fit your joystick base. Thank you for the great question!

    • I have a yanmar ym3110d with factory loader that needs a joystick boot will this fit my loader?

      Thank you for asking! Since this is not a Koyker valve, we would not guarantee it would fit. On a few of the product photos, however, there are dimensions listed to help determine if it could possibly fit.

    • I have a Koyker 120 that attached to a Yanmar 1720D. It looks about 20 years old. Would the boot fit that model? Thanks

      Greetings! Thank you for reaching out. Yes, this part should fit.

    • I have a Koyker 210 loader with joystick. Is K664541 the correct boot?

      Thank you for reaching out. Yes! This is the correct part.
