Engine Fluids, Gear Oil & Filter Specifications
| Engine Oil Viscosity & Standard | SAE 10W-40 API SL/SJ JASO MA/MA2 (Wet Clutch) |
|---|---|
| Engine Oil Capacity | 1.0 L (drain) / 1.1 L (total) |
| Final Drive / Gearbox Oil | Uses engine oil (Shared crankcase wet clutch system) |
| OEM Oil Strainer Part Number | 15421-M9Q-000 (Cleanable mesh screen) |
| OEM Air Filter Element Part Number | 17211-N01-000 |
| Spark Plug Model & Electrode Gap | NGK D8EA (0.6 – 0.7 mm) |
Field note: Because the Wolf Classic 150 uses a wet clutch integrated into the crankcase, NEVER use friction-modified JASO MB scooter oils. Using JASO MB oil will cause severe clutch slippage. Always use JASO MA/MA2 certified motorcycle oil (1.0L drain refill).
Charging & Electrical System
| Component | AGM Battery (12V 6Ah) |
|---|---|
| OEM Part Number | YTX7A-BS |
| Dimensions | 150 x 87 x 93 mm |
| Torque Spec | Terminal screws: Hand tight |
| Fluid/Electrical Notes | Sealed Lead Acid (AGM) |
| Cross-Compatibility | Many GY6 150cc scooters |
Field note: "Hand tight" on AGM terminal screws does not mean loose — a genuinely loose terminal arcs under load and can melt the plastic terminal cover, while an over-tightened terminal (using a wrench instead of a screwdriver) strips the soft terminal post threads on this sealed battery, which cannot be repaired and requires full battery replacement.
