Adding Hydraulic Fluid to New Holland 555E Tractor: Step-by-Step

Regular hydraulic fluid checks keep your 555E's loader, backhoe, and 3-point hitch operating smoothly.

Procedure

1. Park safely: Level ground, parking brake engaged, engine OFF, bucket/implement lowered.
2. Open hood: Release latches; prop securely.
3. Locate reservoir: Rear of engine compartment, typically left side. Transparent/sight gauge with FILL/LOW marks. Cap labeled "HYDRAULIC FLUID" or similar.
4. Clean area: Wipe cap & surroundings — prevent contamination.
5. Remove cap: Unscrew (may have dipstick attached).
6. Check level: Dipstick shows COLD/HOT ranges. Check COLD if engine cold; HOT if warmed up.
7. Add fluid: Use clean funnel. Pour NH 410B / 134D equivalent (UTF — Universal Tractor Fluid meeting Ford M2C134D, NH 410B, JDM J20C). Fill to FULL mark — do not overfill.
8. Reinstall cap/dipstick: Tighten securely.
9. Cycle hydraulics: Start engine, run at idle. Operate loader/backhoe/3-pt through full cycles 3–4x to purge air.
10. Recheck level: Top up if needed after cycling.
11. Close hood.
