Description
About the Mazda Pickup B2300 Crank Shaft
This is the crankshaft for the Mazda B2300. The crankshaft converts the pistons’ up-and-down motion into the rotation that drives the transmission, and it must run true and balanced for the engine to be smooth. A damaged or worn crankshaft causes knocking, vibration, and eventually engine failure, so it is replaced during a rebuild. This one is forged steel with internal balance.
On fitment, the Mazda B2300 is the US-market gas pickup, a rebadged Ford Ranger with the 2.3L inline-4. The early trucks used the Ford 2.3L ‘Lima’ engine and the later trucks the 2.3L Duratec, which are different engines with different crankshafts, so confirm the engine code by VIN; the live FAQ states the listing is for the 2.3L in B2300 models from 1994 to 2001. Unlike the B2500, which spans a gas and a diesel engine, the B2300 is unambiguously the US gas engine.
On condition, the journal diameters listed (2.398 in main, 2.123 in rod) are the standard specs, so for a used crankshaft the actual measured journal diameters, straightness, and whether it is standard or reground undersize must be confirmed. The live page is honest that fitting a crankshaft is an internal engine job requiring full teardown, torque specs, and balancing, for experienced mechanics; that framing is kept, and the bearing clearances should be checked with plastigage and the bearing sizes confirmed.
What To Confirm Before You Order
| Item | Details |
|---|---|
| Engine | US 2.3L (Ford 2.3L Lima or Duratec), by VIN. |
| Journals | Measured diameters; standard or reground undersize. |
| Install | Internal engine job; bearing fit and balancing. |
Things to Confirm Before Ordering
The exact engine code (Ford 2.3L Lima or Duratec), by VIN
The measured main and rod journal diameters, and straightness
Whether the crankshaft is standard or reground undersize
The matching bearing sizes for the bearing fit
What Is Included, What Is Not Included
| Item | Details |
|---|---|
| INCLUDED | The B2300 crankshaft as confirmed for your engine; exact specification confirmed at order. |
| NOT INCLUDED | Main and rod bearings, gaskets, or balancing service unless confirmed at order. |
| Tools You Need | Internal engine service: full teardown, main and rod bearing fit (plastigage), torque-to-spec assembly, and balancing. A professional engine job for an experienced mechanic. |
Vehicle Compatibility
This crankshaft is offered for the Mazda B2300, confirmed by engine. Key fitment points:
| Vehicle | Compatibility |
|---|---|
| Mazda B2300 | US 2.3L inline-4 (Ford Ranger twin) |
| Engines | Ford 2.3L Lima (early) or 2.3L Duratec (later) |
| Live FAQ | 2.3L in B2300 models, 1994 to 2001 |

Fitment Assistance
Not sure which B2300 crankshaft you need? Call (240) 301-0095 with your VIN. Our team confirms the engine code and the measured journal sizes before your order ships.
Condition and Inspection
Quality control for this part includes:
Engine code confirmed for your VIN before shipping
Main and rod journals measured
Straightness checked
Standard-versus-reground confirmed
Matching bearing sizes identified before purchase
Because this is a used internal engine part, we confirm the measured main and rod journal diameters, the straightness, and whether the crankshaft is standard or reground undersize, along with the matching bearing sizes. Fitting a crankshaft is an internal engine job requiring full teardown, bearing fit, torque specs, and balancing, so we route the install to an experienced mechanic.
