Frequently Asked Questions
What is included in a John Deere loader engine overhaul kit?
Our John Deere engine overhaul kits include pistons, rings, sleeves, main and rod bearings, and gasket sets for a full internal refresh. They are built for rebuilding high-hour or worn loader diesels on the 6068, 6.359, and 6.414 platforms. Contents can vary slightly by kit, so check the product listing for the exact parts covered.
Which engine rebuild kit fits a John Deere 544E loader?
The 544E is covered by the 6.359T Turbo overhaul kit (SKU EOKJD6359B), which also fits the 544G. The 544B, 544C, and 544D are covered by the 6068 Turbo kit (EOKJD6068B) and the 6.414 kit (EOKJD6414B). Match the kit to your engine model, and our parts team can confirm fitment if you are unsure.
What bore and pin size do these John Deere loader rebuild kits use?
These kits use a 4.19 bore with either a 1.375 or 1.625 pin depending on the engine platform. The 6068 Turbo and 6.414 kits use a 1.625 pin, while the 6.359 kit uses a 1.375 pin. Confirming the correct bore and pin for your engine ensures the pistons and bearings match.
Do you have turbo and naturally aspirated engine rebuild kits for John Deere loaders?
Yes, Broken Tractor carries both naturally aspirated and turbocharged variants. For example, the 6068 Turbo kit (EOKJD6068B) and the 6.359T Turbo kit (EOKJD6359B) are for turbocharged engines, while the 6.359 kit (EOKJD6359A) fits naturally aspirated applications. Choose the kit that matches your engine's aspiration.
How do I know which John Deere loader overhaul kit matches my engine?
Fitment depends on your engine platform, bore, pin size, and aspiration, so match those details to the kit before ordering. Loaders like the 624E, 640D, 643D, and 648D are covered by the 6068 Turbo kit (EOKJD6068B). If you are unsure which kit fits your machine, call our parts team at (800) 909-7060 to confirm.
