Case 588H Forklift – Parts, Specs & Serial Numbers

Description:

The Case 588H is the most powerful model in Case’s H-Series rough terrain forklifts, engineered for high-capacity lifting, exceptional off-road handling, and maximum reach. With a 8,000 lb lift capacity, Tier 4 Final engine, and optional 4WD, the 588H is ideal for lumberyards, industrial construction, and large-scale agricultural jobs.

It shares the advanced hydraulic and emissions systems of the 586H, but with a beefed-up frame, heavier mast, and longer wheelbase to support higher loads and greater stability. This is Case’s top-tier forklift for demanding material handling.

Maintenance Essentials:

• DPF Cleaning & Sensors: Clean periodically and replace sensors as needed. Shop DPF parts and filter kits

• Hydraulic Cylinders: High-pressure lift applications wear seals quickly. Browse Case 588H cylinder seal kits

• Brake System: Wet-disc brakes may need seal and disc replacement. Find 588H brake parts

• Transmission Seals: Common leak point on high-hour units. Get shuttle transmission seal kits

Common Issues & Quick Fixes:

• DPF Not Regenerating: Ensure machine reaches operating temp and load. Use manual regen function if needed.

• Hydraulic Lag or Weak Mast Lift: Replace return filters and inspect hydraulic pump output.

• Loss of Shuttle Engagement: Fluid level low or internal shuttle seal failure. Order power shuttle rebuild kits

• Steering Tight on 4WD Models: May indicate orbitrol or priority valve wear.

Serial Number Location:

• Primary Tag Location: Left frame rail behind front tire or near operator platform

• Format: Begins with “NFH” or “JJG” followed by numeric digits (e.g., NFH00XXXXXX)

Pro Tip:

Because the 588H operates at the upper range of forklift capacity, it’s critical to service hydraulic components more frequently than smaller models. Always use correct hydraulic fluid grade and consider using heavy-duty synthetic for extreme environments.
