Yamaha put three snow-clearing machines into one service manual: the YS624T/W, the YS624T/WM and the YS828T/WM. The part number is LIT-19616-00-16, and this page is for the YS624T/W.
Having the three together is genuinely useful, because auger, drive and chute hardware overlap heavily while a few assemblies do not. The manual keeps those distinctions explicit and tags specifications by model code.
What the book covers
- Engine service with torque and clearance figures
- Auger and impeller assemblies, including shear-pin and belt work
- Drive system, friction disc or transmission, and adjustment settings
- Electrical circuits with diagrams
- Symptom-based troubleshooting
Specifications are given as published figures throughout, so a worn belt, a slipping friction disc or an out-of-tolerance clearance can be judged against a number instead of an impression.
Before ordering, check the YS624T/W code on the machine. The W and WM designations are not interchangeable for every part.
