FAQ

Is this the correct first service kit for the XF425?
Yes. This kit includes the primary components commonly replaced during the 20 hour break-in service interval.

Why are two gallons of oil included?
The XF425 has a higher oil capacity, requiring more than one gallon for a complete oil change.

Why are multiple O-rings included?
The XF425 uses multiple sealing points for oil and drain components. Replacing them during service helps maintain proper sealing and leak prevention.
