Up to 32 Tons of Force • Double-Acting Design • Clevis Mount • Rebuildable Construction

Replace a worn or leaking log splitter cylinder with the 31-112 Hydraulic Log Splitter Cylinder. Built with a 4.5-inch bore, 24-inch stroke, and 1.75-inch chrome-plated rod, this heavy-duty cylinder is designed for many log splitters using a double-ear clevis mounting system.

The cylinder produces approximately 28 tons of splitting force at 3,500 PSI and up to 32 tons at its 4,000 PSI maximum operating pressure. Its double-acting design provides hydraulic power during both extension and retraction, while replaceable seals allow the cylinder to be rebuilt rather than discarded after normal seal wear.

Key Features & Benefits

• 4.5-Inch Bore
  Provides substantial piston area for generating high splitting force from a compatible hydraulic system.
• 24-Inch Stroke
  Offers the travel commonly used on full-size residential and commercial log splitters.
• Up to 32 Tons of Splitting Force
  Produces approximately 28 tons at 3,500 PSI and 32 tons at the maximum 4,000 PSI operating pressure.
• Double-Acting Operation
  Two hydraulic ports power the cylinder in both forward and reverse directions.
• 1.75-Inch Chrome-Plated Rod
  The heavy-duty rod provides strength and a corrosion-resistant working surface.
• Clevis-Mount Design
  Uses double mounting ears with 7/8-inch inside spacing for compatible clevis-mount log splitters.
• Rebuildable Construction
  Internal seals can be replaced to extend the cylinder’s service life.
• Black Powder-Coated Finish
  Helps protect the cylinder body from corrosion and outdoor exposure.
• Common OEM Replacement Configuration
  Designed as a replacement for many compatible Tractor Supply, Huskee, Husky, SplitMaster, Oregon, SpeeCo, CountyLine, and similar log splitters. Exact fitment must be confirmed before ordering.

Hydraulic Splitting Performance

The amount of force produced depends on the hydraulic system’s actual operating pressure:

The 4,000 PSI figure is the cylinder’s published maximum operating pressure and should not be exceeded. Actual splitter performance also depends on the pump, control valve, pressure-relief setting, hoses, fittings, engine, and overall hydraulic-system condition.

Replacement Applications

The 31-112 may fit many log splitters equipped with a compatible double-ear clevis-mount cylinder, including selected models sold under these names:

• Tractor Supply
• CountyLine
• Huskee
• Husky
• SplitMaster
• Oregon
• SpeeCo
• Other compatible clevis-mount splitters

Brand compatibility does not guarantee fitment across every model. Compare all mounting, length, rod, port, and pin measurements with the existing cylinder before ordering.

Quick Specifications

The current product page supplies the pressure, force, port, rod, length, and mounting specifications. Tool Tuff’s product catalog confirms the 1-1/8-inch clevis holes, 7/8-inch inside spacing, and approximately 60-pound weight.

Package Contents

• One 31-112 hydraulic log splitter cylinder

Hydraulic hoses, fittings, mounting pins, control valve, pump, wedge, hardware, and hydraulic fluid are not listed as included.

Important Fitment Information

This cylinder is not universal. Before purchasing, compare the replacement cylinder with the existing cylinder and verify:

• 4.5-inch bore
• 24-inch stroke
• Retracted and extended lengths
• Clevis-ear spacing
• Mounting-pin diameter
• Rod-end hole diameter
• Hydraulic-port size and location
• Available installation clearance
• Hydraulic-system pressure rating

The product page describes this cylinder as a common no-modification replacement for many splitters, but individual models and production years can use different mounting dimensions.

Important Hydraulic Information

The splitter’s pressure-relief valve must be properly adjusted and must not allow the cylinder to exceed 4,000 PSI. All hoses, valves, fittings, pumps, and other hydraulic components must be rated for the system’s operating pressure.

Relieve hydraulic pressure and securely support all components before disconnecting the existing cylinder. Hydraulic fluid under pressure can penetrate skin and cause serious injury.
