Machine Background
The International Harvester 100E is a mid-sized crawler loader manufactured through the 1970s known for its robust mechanics and versatility. Equipped with the International Harvester DT239 3.9L 4-cylinder diesel engine, it delivers around 70 horsepower gross (65 hp net), suitable for general construction, agriculture, and industrial applications. This model features a full power shift transmission with three forward and three reverse speeds, complemented by a rugged spur gear final drive.
The track loader weighs approximately 15,481 pounds (7,022 kg) and runs on taped track shoes roughly 16 inches wide, offering stability and traction across varying terrains. Operator safety is provided via a four-post ROPS canopy, with optional cabs enhancing operator comfort.
Hydraulic and Fuel Systems
The hydraulic system operates as an open-center configuration with a capacity of about 15 gallons (56.8 liters), operating at a pressure of 2150 psi (148.2 bar) and pump flow of roughly 21.8 gpm (82.5 lpm). Fuel capacity is 30 gallons (113.6 liters), allowing extended operational periods between refueling.
Seal Kit Importance
Track loader seal kits are essential in maintaining the integrity of the track rollers, final drives, and gearboxes. Seals prevent dirt, water, and debris contamination while keeping lubricants contained essential for smooth operation and longevity. Wear or failure of seals leads to premature bearing and gear damage, high maintenance costs, and increased downtime.
Seal kits for the International Harvester 100E typically include:
Operators and maintenance professionals highlight the value of having comprehensive seal kits on hand to minimize machine downtime during repairs. Accessing correct kits for aging models like the 100E requires knowledgeable suppliers familiar with vintage International Harvester and Dresser equipment. Some specialized vendors provide same-day shipping and support for part selection.
Upgrading to modern seal compounds with better wear and corrosion resistance can extend interval times and reduce overall life cycle costs. Anecdotally, well-sealed track loaders like the 100E maintain higher resale values and reliability on demanding job sites.
Conclusion
The International Harvester 100E Track Loader remains a dependable machine when maintained with attention to critical components such as track seals. Utilizing proper seal kits and adhering to preventive maintenance practices ensures smooth operation, longer component life, and reduced operational disruptions in various heavy equipment applications.

Seal kits for the International Harvester 100E typically include:
- Roller seals to protect idlers and track rollers
- Final drive seals preventing oil leaks
- Carrier and sprocket seals ensuring smooth track rotation
- Routinely inspect track assemblies for oil leaks or dirt accumulation indicative of seal failure.
- Replace seals proactively using comprehensive kits during major track or undercarriage services.
- Use OEM or high-quality aftermarket seals to ensure compatibility and durability.
- Clean mating surfaces meticulously before installing new seals to prevent premature wear.
- Monitor grease and oil levels in undercarriage components regularly.
- ROPS: Roll Over Protective Structure designed to protect operators during incidents.
- Open Center Hydraulic System: System where fluid flows continuously through a control valve when in neutral.
- Seal Kit: Collection of replacement seals and gaskets for specific machine assemblies.
- Final Drive: Gear reduction unit within the track drive system.
- Track Rollers: Rollers that support and guide the tracks along the undercarriage.
