* Engine Variations: IH 656 tractors came with different engine options. The oil capacity can vary between these engines.
* Filter Type: The type of oil filter used can also slightly affect the total oil capacity.
To find the correct oil capacity for your tractor, you need to:
1. Locate your tractor's engine model number: This information is usually found on a plate attached to the engine.
2. Consult the IH Operator's Manual: The manual will have the specific oil capacity for your particular engine. You can often find manuals online or through IH dealers.
3. Check with an IH Parts Dealer: They can look up the oil capacity for your tractor based on its serial number.
General Tip: It's always best to slightly underfill the engine with oil rather than overfill it. Overfilling can lead to problems like oil foaming and damage to engine components.
