Description
When you pull the valve cover on your old John Deere and see cylinder walls that have seen better days, it's time to get serious about an engine rebuild. This basic kit gives you the foundation pieces to get your 300 series diesel breathing like new again - the pistons, rings, sleeves, and bearings that make the difference between an engine that starts hard and burns oil versus one that fires right up and runs clean.
What You're Getting
- 1.187 inch wrist pins with 2-groove sleeves that match original factory specs
- Complete piston and ring set designed for reliable compression and oil control
- Cylinder sleeves machined for proper bore clearance and long engine life
- Rod and main bearings available in standard plus .010, .020, and .030 oversizes
- All components engineered for engines up to serial number 277,548
Built for Real Farm Work
This kit fits those dependable 300 series John Deere diesels that powered everything from utility tractors to combines. Whether you're rebuilding the engine in a 2020 that's been pulling implements for decades or bringing back a 4020 that's the backbone of your operation, these are the same quality components that went into these engines when they were new.
Made to Last
Farm engines take punishment that would kill a highway engine - dust, moisture, temperature extremes, and hours at full throttle under load. These components are manufactured to handle that abuse, with proper metallurgy and tolerances that ensure your rebuilt engine will give you years of reliable service.
Good to Know
You'll need to specify bearing sizes when ordering since every engine wears differently. Measure your crankshaft journals carefully or have them checked at a machine shop to determine if you need standard, .010, .020, or .030 bearings. The 1.187 inch pin specification is critical - verify this matches your engine before ordering.
