Case 586G Forklift – Parts, Specs & Serial Numbers

Description:

The Case 586G is a heavy-duty rough terrain forklift built for high-capacity lifting in demanding construction, lumber, and agricultural environments. With a powerful Tier 3 turbocharged engine and a rugged 4WD option, the 586G delivers outstanding traction, lift height, and ground clearance for uneven terrain.

Built as part of Case’s “G Series,” the 586G features modern upgrades over previous models including better operator visibility, improved hydraulic response, and easier serviceability. With a 6,000 lb lifting capacity and a maximum lift height exceeding 22 feet (with a 3-stage mast), the 586G is ideal for bulk handling and large material movement.

• Cooling System: Clean radiator and replace hoses periodically to prevent overheating.

Common Issues & Quick Fixes:

• Hydraulic Slowdown in Cold Weather: Switch to cold-weather-rated hydraulic fluid or inspect the suction screen.

• No Forward or Reverse Movement: Likely a shuttle clutch issue or low pressure. Power shuttle kits available.

• Brake Fade: Internal seal wear or contaminated fluid. Use OEM-compatible brake fluids and replace discs or seals.

• Engine Overheating: Clogged radiator or fan failure – ensure cooling fins are clean and belt tension is correct.

Serial Number Location:

• Primary Location: On left side of the machine frame behind the front tire or near the operator platform.

• Format: Often begins with “JJG” or similar, followed by numeric sequence (e.g., JJG01XXXXXX)

Pro Tip:

The 586G is optimized for high-cycle operations. Keep extra hydraulic filters on hand and inspect lift cylinder seals monthly when working in dusty or sandy environments. Upgrade to LED lighting for enhanced visibility in low-light job sites.
