Description
When you’re doing an engine overhaul and need to machine things back to proper spec, these honeable piston pin bushings give you the flexibility to get the fit just right. Instead of hoping for a perfect press fit, you can install these bushings and then hone them to match your piston pins perfectly. That’s the kind of precision work that makes the difference between an engine that runs for years and one that gives you trouble down the road.
What You’re Getting
- Honeable design lets you machine the bore to exact specifications after installation
- Quality Tisco construction built to handle the heat cycles and loads of diesel engines
- Soft material that machines cleanly without work hardening or chatter
- Six bushings per set since your engine uses six total for a complete rebuild
- Direct replacement for worn or damaged original bushings in connecting rods
Built for Real Farm Work
These bushings work in John Deere diesel engines where precision matters most. Whether you’re rebuilding a loader tractor engine that’s seen hard use or overhauling a row-crop tractor that needs to run reliably through planting and harvest, proper piston pin clearances are critical for long engine life and good oil pressure.
Made to Last
Tisco uses materials that can handle the constant hammering and heat that diesel engines dish out. The soft bushing material machines easily but won’t distort under load once it’s in service. Quality control ensures consistent wall thickness and bore concentricity so your machine work comes out right the first time.
Installation Notes
These bushings require proper machining equipment to hone to final size – this isn’t a home garage job. Your machine shop will press them in, then hone to match your piston pin diameter with the clearance specified in your service manual. Most rebuilders check the connecting rod bore and straightness before installing new bushings.
