Key Notes:

• Application: Crankshaft and bearing kit for the 4045 diesel engine
• Dimensions: Long nose, 60mm / 2.36" nose
• Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms:

Use at a bottom end rebuild on the 4045 engine — the crank comes with the bearings sized to it, which saves matching them separately after the block is apart.

Kit Includes:

• Crankshaft
• Main thrust bearing
• Main bearing set
• Connecting rod bearing set

Why Choose Broken Tractor:

• ✅ Crank and Bearings Matched: Crankshaft supplied with the thrust bearing and both bearing sets, so nothing is left to source mid-rebuild.
• ✅ Nose Style Called Out: Long nose, 60mm / 2.36" nose — the detail that separates this crankshaft from the others for these engines.
• ✅ Covers 17 Models: One kit across the machines listed rather than ordering the crank and bearings separately.
