| Oil Filter (Oil Injection System) | Annually | Associated with the oil injection system. |
| Drive Belt | Check every 50 hours; estimated lifespan between 2 400 and 4 800 km | Check for wear or damage, or if performance feels off. The owner's manual contains specifications for track adjustment and belt tension. |
| Spark Plug | Clean after engine break-in; replace as needed | Remove and clean after break-in. Replace if misfires, rough idle, or loss of power. It is advisable to carry extra spark plugs. |
| Air Filter | Not specified; inspect and clean/replace as part of general maintenance | Typically inspected, cleaned, or replaced during pre-season or periodic maintenance. |
| Coolant | Flush every 4-5 years; check level and condition before and during the season | Check level and condition before the snowmobiling season and occasionally during the season to prevent engine overheating. The Skandic 503 is a 2-stroke engine. |
