Frequently Asked Questions
What is included in a John Deere wheel loader short block?
Each rebuilt short block from Broken Tractor includes the block, crankshaft, pistons, rings, and bearings. It is a machined foundation assembly ready for final assembly during an engine rebuild or replacement. Cylinder head and external components are not part of the short block.
Which short block fits a John Deere 444E or 444G loader?
The 4045T short block (SKU JD-4045T-SB) fits the 344G, 344H, 444E, 444G, and 444H loaders. The earlier 444, 444C, and 444D use the 6.329 short block (SKU JD-6329-SB) instead. Match the SKU to your engine configuration to confirm the correct fit.
Do you have a short block for the John Deere 544 and 624 loaders?
Yes, Broken Tractor carries the rebuilt 6.414 Turbo short block (SKU JD-6414T-SB) that fits the 544B, 544C, 544D, 624E, 624G, 750, and 750B. This is the turbo configuration built for those larger loaders.
What is the difference between the 6.329 and 6.414 turbo short block for John Deere loaders?
The 6.329 short block (SKU JD-6329-SB) is a natural configuration for the 444, 444C, and 444D, while the 6.414 turbo short block (SKU JD-6414T-SB) is the turbo variant for the 544 through 750 series. They are not interchangeable, so choose the one that matches your engine size and loader model.
How do I confirm the right short block for my John Deere wheel loader?
Match your loader model and engine configuration to the SKU listed for each short block, since fitment can depend on the exact series and engine variant. If you are unsure which one your machine uses, our parts team can help verify at (800) 909-7060.
