Description
When your engine starts running rough, uses more oil than usual, or shows excessive white smoke from the exhaust, there’s a good chance your valve guides are worn out. These small but critical engine components keep your intake and exhaust valves properly aligned so your engine can breathe right and maintain compression. A worn valve guide lets the valve wobble around, which leads to poor sealing, oil burning, and eventually valve damage you definitely don’t want to deal with.
What You’re Getting
- Precision-machined guide that keeps your intake valve perfectly aligned for proper sealing
- Quality construction designed to handle the heat and stress of engine operation
- Direct replacement that installs without modifications or special tools
- Part of the valve train system that’s essential for proper engine breathing
Built for Real Farm Work
This valve guide fits International Harvester 100 series, 200 Series, Super A-1 Series (prior to S/N 310300), Super AV-1 Series (prior to S/N 310300), and Super C Series tractors with the 4-cylinder gas 123 CID engine. These are the utility tractors that have been the backbone of smaller farming operations for decades, handling everything from cultivation and mowing to loader work and general farm chores.
Made to Last
Valve guides take a beating from constant valve movement and engine heat, so this one’s built from quality materials that resist wear and maintain proper clearances. It’s designed to provide thousands of hours of reliable service under normal operating conditions.
Good to Know
Installing valve guides requires pressing out the old ones and pressing in the new ones—it’s definitely a job for someone with engine experience and the right tools. Your engine uses 8 valve guides total, so if one’s worn out, it’s smart to check the others while you’re in there. A machine shop can handle the installation and ensure proper fit and alignment.
