Description
When you hear a rattling noise from down in the oil pan or notice your oil pressure dropping, it’s often the oil pump gear-shaft assembly that’s telling you it’s had enough. This assembly is what drives your engine’s oil pump, keeping that 134 cubic inch flathead motor properly lubricated through long days of work. When it starts wearing out, you’ll know it—and you’ll want to fix it before it leaves you stranded in the field.
Key Features
- Precision-machined shaft and gear designed for the 3/4 inch wide gear specification on Ford N-series tractors
- Heat-treated components that resist wear from constant rotation and oil pressure demands
- Direct replacement assembly that restores proper oil pump drive without modifications
- TISCO quality construction built to handle the demands of vintage Ford engines
Built for Real Farm Work
This assembly fits the legendary Ford 8N, 9N, and 2N tractors—the workhorses that helped modernize American agriculture from 1939 to 1952. Whether you’re using your N-series for hay work, cultivating, or just keeping the farm tidy, this gear-shaft assembly ensures your engine gets the oil circulation it needs to keep running strong.
Made to Last
Vintage Ford engines are known for their durability, but they need proper oil pressure to deliver that reliability. This TISCO assembly is manufactured to original specifications using quality materials that can handle the continuous duty these old engines were built for. The gear teeth are properly hardened to resist wear, and the shaft is machined to precise tolerances for smooth operation.
Installation Notes
This is an engine-internal repair that requires removing the oil pan and oil pump assembly. While you’re in there, it’s a good time to check your oil pump gears and housing for wear. Make sure to prime the oil pump with fresh oil before starting the engine, and always use the proper viscosity oil for your operating conditions.
