Description

When your Massey’s steering wheel starts feeling heavy during turns or you notice hydraulic fluid dripping around the steering ram, those seals are telling you it’s time for a rebuild. Power steering problems rarely appear suddenly – they develop gradually until you can’t ignore them anymore. Early symptoms include steering that feels heavy when cold but improves as fluid warms up. You might notice the steering wheel doesn’t return to center as quickly, or holds slight pressure to one side. This complete O-ring kit gives you everything needed to bring that smooth steering back.

What You’re Getting

This complete kit ensures you fix the problem once instead of chasing individual seal failures over multiple seasons. All the seals have aged together, so when one fails, others aren’t far behind
High-quality O-rings designed to handle the constant pressure cycles of power steering operation
The cost difference between replacing one seal and the complete set is minimal, but the labor involved remains the same. By replacing all seals during a single rebuild, you restore full steering performance and gain years of trouble-free operation.
Precision-molded seals that maintain proper hydraulic pressure and prevent internal bypass

Built for Real Farm Work

This power steering conversion kit is specifically engineered for Massey Ferguson 100 series models 165, 168, 175, 178, 185, and 188, plus 200 series models 265, 275, and 290 equipped with Perkins 4.212, 4.236, or 4.248 diesel engines. These Massey Ferguson models are workhorses across diverse farming operations including row crop cultivation, hay production, livestock farming, and general farm maintenance. The 165 series became legendary for durability and versatility, while larger models like the 275-290 series provide increased power for heavy field work, loader operations, and demanding implement applications.

Made to Last

These seals are manufactured from hydraulic-grade materials that resist the temperature swings and pressure cycles that come with farm work. Modern seal materials resist the deterioration that plagued original equipment, meaning less frequent rebuilds. They’re built to handle the constant demands of power steering systems without hardening or cracking over time.

Installation Notes

Rebuilding a power steering ram requires cleanliness and attention to detail for success. Start by thoroughly cleaning the external ram before disassembly – contamination entering during rebuild causes immediate seal failure. Install new seals using proper seal installation tools – improvised tools damage seals before they’re even in service. Lubricate all seals with clean hydraulic fluid during assembly. Fill with fresh hydraulic fluid meeting Massey Ferguson specifications; contaminated fluid shortens seal life dramatically.
