Two things identify what you need here. The 2019 Wolverine R-Spec EPS carries model code YXE85WPAKW, and its factory service manual is Yamaha part LIT-11616-32-02.
That 2019 book was written broadly. Along with this machine it covers the Wolverine X2, the X2 R-Spec EPS, the X2 R-Spec EPS Hunter and the X2 R-Spec EPS SE, so a shop running a mixed fleet works from one reference rather than five.
Content is factory service material: sequenced disassembly and reassembly, the torque and clearance figures that belong with each step, electrical schematics, and troubleshooting laid out by symptom. Nothing is glossed over on the assumption you already know it, and nothing is padded out either. Check the code on your own machine against the one above before ordering.
