Rear Crankshaft Seal for New Holland T4000, T5000, T6000, T7000 and Case Maxxum Tractors

Description

When your tractor starts leaving oil spots where it’s parked or you notice engine oil on the flywheel housing, chances are your rear crankshaft seal has called it quits. This critical seal sits between the engine and transmission, keeping engine oil where it belongs and preventing contamination that can lead to bigger problems. A leaking rear main seal means lost oil pressure, potential clutch contamination, and expensive cleanup that gets worse if you don’t address it.

What You’re Getting

• Precision 130 x 155 x 12.5mm dimensions for exact OEM fit
• Heavy-duty construction designed for constant crankshaft rotation
• Oil-resistant compound that handles modern synthetic engine oils
• Spring-loaded lip maintains consistent sealing pressure as wear occurs
• Direct replacement that restores factory-level sealing performance

Built for Real Farm Work

This seal fits a wide range of New Holland tractors from the compact T4000 utility series up through the powerful T7000 row-crop machines, plus Case Maxxum and MXU models. Whether you’re running a T5060 on a dairy operation, pulling heavy implements with a T6070 Delta, or doing loader work with a Case Maxxum 140, these engines work hard every day. The NEF Iveco engines in these tractors are built for durability, but seals wear out from normal use and temperature cycling.

Made to Last

This isn’t just any rubber seal – it’s engineered specifically for the demands of agricultural engines that run long hours in dusty, hot conditions. The compound resists swelling from engine oil while staying flexible through temperature extremes. The metal outer case provides rigid support to prevent distortion under the side loads that occur during clutch engagement and PTO operation.

Installation Notes

Replacing a rear main seal typically requires separating the engine from the transmission, so it’s often done during clutch replacement or major engine work. Clean the crankshaft surface thoroughly and check for wear or damage that could cause premature seal failure. A light coat of clean engine oil on the seal lip helps with initial startup.
