Service jobs and parts
Engine oil and filter change
Engine · every 500 hours
John Deere's sheet says to change the engine oil filter after every 500 hours. The sheet does not state the Plus-50 conditions or an interval for ordinary oil, so check your handbook if you use a cheaper oil. The oil is always changed with the filter.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Engine oil | 1 | 15W-40. John Deere Plus-50 II, ≈12 L with filter. Aztec Oils match: EMPROTEC EHPD 15W-40 | check your handbook |
| Engine oil filter | 1 | Genuine John Deere filter | RE504836 |
Step-by-step
- Warm the engine, then park on firm level ground, lower the linkage, loader and any implement, stop the engine, take the key out and chock the wheels.
- Let it stand a few minutes. Hot oil burns, so wear gloves.
- Remove the sump plug and let the oil drain fully.
- Remove the filter, check the old seal came off with it, and wipe the filter head clean.
- Smear a little clean oil on the new filter seal and fit it hand-tight as marked on the filter.
- Refit the sump plug and fill to the full mark on the dipstick.
- Run the engine for a minute, check for leaks, stop it and recheck the level.
