Description

Nothing ruins your day like finding fresh oil underneath your tractor or smelling crankcase fumes in the cab. When your engine’s rear crankshaft seal starts to fail, it lets oil leak out where the crankshaft meets the flywheel housing – and that’s not just messy, it’s expensive. This TISCO replacement seal stops those leaks at the source, keeping your oil where it belongs and your engine protected.

What You’re Getting

Precision-molded seal that matches OEM specifications for a perfect fit
High-temperature rubber compound that won’t crack or harden in engine heat
Double-lip design creates a reliable barrier against oil leakage
Spring-loaded seal edge maintains consistent pressure on the crankshaft
Quality construction that handles the constant rotation and vibration

Built for Real Farm Work

Kubota diesel engines power everything from compact utility tractors to mid-size workhorses handling hay, tillage, and loader work. These reliable engines see thousands of hours in dusty conditions, temperature extremes, and constant stop-and-go operation. When the rear crankshaft seal fails, it usually shows up as oil spots where you park or a gradual drop in your oil level – problems that only get worse with time.

Made to Last

This isn’t just any rubber seal – it’s engineered specifically for the demands of diesel engine service. The high-temperature compound stays flexible through hot summer days and cold winter startups, while the spring-loaded design compensates for normal crankshaft wear. TISCO quality means you’re getting reliable sealing performance that matches OEM standards.

Installation Notes

This is a major repair job that requires splitting the tractor to access the flywheel housing. You’ll need to remove the transmission, clutch, and flywheel to reach the old seal. Take your time cleaning the seal surface and use a proper seal driver for installation – any nicks or improper seating will cause immediate failure. While you’re in there, it’s smart to inspect the flywheel and clutch components.
