Description

When your Ford 800 or 900 series tractor starts developing engine knock or excessive piston slap, a worn piston pin is often the culprit. This critical engine component connects your piston to the connecting rod and takes a beating under the constant pressure and heat of diesel combustion. A failing pin can damage expensive pistons and cylinder bores, so catching it early saves you major rebuild costs down the road.

What You’re Getting

Precision-machined wrist pin that connects piston to connecting rod with factory-tight tolerances
Heat-treated steel construction that handles the intense pressures of diesel combustion
Direct OEM replacement that installs without modifications or special tools
Quality TISCO manufacturing that meets or exceeds original Ford specifications

Built for Real Farm Work

This pin fits the workhorse Ford 800 and 900 series tractors that farmers have relied on for decades of heavy-duty field work. Whether you’re running a three-bottom plow, pulling a hay baler, or operating a loader, these tractors put serious stress on engine internals. The 172 CID diesel engines in these machines were built tough, but after thousands of hours of operation, even the best parts wear out.

Made to Last

Farm engines don’t get babied, and this pin is built to handle whatever you throw at it. The precision manufacturing ensures proper clearances that prevent excessive wear while maintaining the oil film needed for lubrication. Quality steel construction resists the constant loading and unloading cycles that destroy inferior pins.

Good to Know

Installing a piston pin requires engine disassembly and proper pressing tools—this isn’t a field repair. If you’re planning a rebuild, always replace pins even if they look okay since worn pins can cause new pistons to fail prematurely. Check your connecting rod small end for wear and scoring while you’ve got everything apart. A machine shop can measure everything to ensure proper clearances before reassembly.
