Description
When your speed shift transmission starts making noise or won’t shift between ranges smoothly, that grinding sound is usually coming from worn bearings deep inside the transmission. This input bearing is what keeps your transmission’s main input shaft spinning true and quiet, letting you shift from field range to road range without that coffee-can sound that makes your neighbors cringe. If you’ve been stuck in one speed range or hearing metal-on-metal noise during shifts, this bearing will get you back to smooth, quiet operation.
Key Features
- Precise 31.75mm inner diameter and 41.275mm outer diameter for exact fit in Massey Ferguson syncro transmissions
- Heat-treated steel construction handles the high loads and speeds of transmission operation
- Sealed design keeps gear oil in and contaminants out, even in dusty field conditions
- Direct replacement for factory bearing – no modifications needed
Built for Real Farm Work
This bearing fits the workhorse tractors that built agriculture – your 200 series utility tractors like the 275, 290, and 298, all the way up through the powerful 600 series machines like the 675, 690, and 698. These are the tractors that handle everything from loading hay to deep plowing, and they need transmissions that shift smoothly whether you’re creeping through the barnyard or heading down the road to the next field. The 4200 and 4300 series tractors also rely on this same bearing for their advanced speed shift systems.
Made to Last
Quality bearings are properly heat-treated and manufactured to handle the demanding conditions of agricultural use. This bearing is built to the same specifications as the original, using materials that can handle the constant rotation, shock loads from rough terrain, and temperature changes that come with farm work. The precision tolerances ensure smooth operation and long service life.
Installation Notes
This is a major transmission repair that requires splitting the tractor and disassembling the transmission case – definitely shop-level work that needs proper tools and transmission knowledge. When you’re in there, it’s smart to check the related seals, circlips, and other transmission bearings since everything’s already apart. Have fresh gear oil ready for reassembly, and take your time with the syncro timing to ensure smooth shifting when you’re done.
