Frequently Asked Questions
Which crankshaft fits a Case W11 wheel loader?
The W11 uses the crankshaft for Case 207 cui non-turbo diesel engines, part number A144011. Broken Tractor also carries the crankshaft front seal A39110 for Case 188 and 207 diesel engines, which fits the W11. Match the part to your engine displacement to confirm the correct fit.
What crankshaft do I need for a Case W14B or W14C loader?
It depends on the engine in your machine. The Cummins 4-390 and 4T-390 crankshaft (SKU 3907803) fits the W14B, while the Cummins 6590 and 6T590 crankshaft (SKU J918324) fits both the W14B and W14C. Confirm your engine model and turbo configuration before ordering, since both engine families appear across these loaders.
Which crankshaft fits a Case 621, 621B, or 621C wheel loader?
The 621, 621B, and 621C use the crankshaft for Case Cummins 6590 and 6T590 engines, part number J918324. This same crankshaft covers other 9030 series and large loader models. Match the crankshaft to your engine displacement and turbo setup to verify fitment.
What crankshaft fits a Case 9030 or 9030B?
The 9030 and 9030B use the Cummins 6590 and 6T590 crankshaft, SKU J918324. This assembly is built for the larger Cummins engine family used in these machines. If you are unsure which engine your loader carries, match the part number to your engine or confirm with the parts team.
