  • Our custom billet PTO crank end for the Patriot 850 crankshaft uses our proven triple-wide bearing set up with C4 press-fit bearings with lock ring. This eliminates the big OE roller bearing from moving in the crankcase and PTO crank end separation from the rod pin (both caused by the hammer effect of the clutch) which damages the case halves.


    If you choose not to have this option, your motor will not have a warranty.  If you choose a warranty option and not PTO end option you will be refunded for the cost of the warranty and your motor will have no warranty.


    NOTE: all 90 day waranty motors will have OE style aftermarket pistons along with upgraded PTO end, If you choose to have a 1 year warranty for an extra $400 your motor will have OEM pistons along with upgraded PTO end.
