Crankshaft Coupling for David Brown 900, 1200, 1400, 90 and 94 Series Tractors

Description

When you’re troubleshooting engine power problems or weird vibrations coming from the front of your David Brown tractor, this little coupling might be the culprit. The crankshaft coupling connects your engine’s crankshaft to the transmission input shaft, transferring all that engine power to your wheels and hydraulics. When this part starts wearing out, you’ll notice rough operation, power loss, or complete drivetrain failure right when you need your tractor most.

Key Features

• Direct factory replacement that fits perfectly without modifications or adapters
• Precision-machined to handle the constant torque and stress of heavy farm operations
• Durable construction built to last through seasons of demanding work
• Engineered to reduce vibration and wear on connected drivetrain components

Built for Real Farm Work

This coupling is designed for David Brown’s most popular tractor lines – from the versatile 900 series utility tractors to the powerful 1400 series row-crop machines. Whether you’re running a 990 with a loader, pulling implements with a 1200, or doing heavy fieldwork with a 1490, these tractors depend on this coupling to transfer power from engine to transmission smoothly and reliably.

Made to Last

Farm equipment faces constant shock loads, temperature swings, and dirty conditions that destroy lesser parts. This coupling is manufactured to the same specifications as the original factory part, using materials that resist wear and maintain proper alignment even after thousands of hours of operation. The precision fit ensures your engine and transmission work together efficiently.

Installation Notes

Replacing this coupling requires splitting the tractor between engine and transmission, so it’s a job for someone comfortable with major tractor work. Always support both the engine and transmission properly during the procedure. Check your flywheel and transmission input shaft for wear while you’re in there – a worn coupling often indicates other drivetrain issues that should be addressed at the same time.
