Description

When your diesel engine starts running rough, losing power, or producing excessive smoke, the problem might be deeper than a bad fuel filter or dirty injector. If the injector sleeve in your cylinder head is worn or cracked, it can throw off the precise fuel injection timing and spray pattern your engine needs to run properly. This replacement sleeve gets your Fiat or Ford New Holland tractor back to delivering the smooth, reliable power you depend on.

What You’re Getting

Precision-machined sleeve that restores proper injector sealing and positioning in the cylinder head
Durable construction that handles the high-pressure fuel injection system without cracking or distorting
Direct replacement that fits exactly where your original sleeve went
OEM-quality materials that resist fuel corrosion and thermal cycling

Built for Real Farm Work

This injector sleeve fits Fiat 55 and 90 series tractors along with Ford New Holland 30 series models. Whether you’re running a Fiat 160-90 through heavy tillage work or using your Ford New Holland 8630 for loader duties and field cultivation, these tractors earn their keep on working farms where reliable diesel performance is essential.

Made to Last

Injector sleeves take a beating from high-pressure fuel injection cycles and engine heat. This sleeve is manufactured to handle those demanding conditions while maintaining the precise tolerances needed for proper fuel delivery. The materials resist corrosion from modern diesel fuels and maintain their dimensional stability through thousands of heat cycles.

Good to Know

Replacing an injector sleeve typically requires cylinder head work and is usually part of a larger engine rebuild or major repair. While you’re in there, it’s smart to inspect all related injection components and consider having your injectors professionally cleaned or rebuilt. This ensures your fuel system works together as a complete, efficient unit.
