22R & 22R-E 13411-38010 Crankshaft for Toyota Hilux 4Runner Celica

Technical Q&A: Toyota 22R Crankshaft

Are there any Toyota 22R vs 22RE crankshaft differences?

No, there are no physical differences in the crankshafts between the carbureted 22R and the fuel-injected 22R-E engines. Both iterations of the 2.4L engine block utilize the identical rotating assembly featuring a 92.0mm bore and 89.0mm stroke, alongside the same 6-bolt flywheel flange. The OEM 13411-38010 crankshaft serves as a direct, drop-in replacement for both engine versions.

What causes premature wear on the 22R main journals?

While exceptionally durable, the 22R engine’s primary vulnerability over decades of use is oil starvation. Weakening oil pumps or stretched timing chains wearing through the timing cover can introduce coolant/debris into the oil pan. This contamination bypasses the filter, scoring the 60.0mm main journals and producing distinct engine knocking. Replacing the damaged unit with an induction-hardened crankshaft prevents immediate failure recurrence.

What are the torque specifications for installing the 13411-38010 crankshaft?

According to the Toyota Factory Service Manual (FSM), the main bearing cap bolts must be tightened to 103 Nm (76 ft-lb). The connecting rod cap nuts should be torqued to 69 Nm (51 ft-lb). These are standard torque specifications, not torque-to-yield (TTY), but fasteners should still be inspected for stretching before reuse. Always employ high-quality assembly lube during installation.

Can this replace the aftermarket 13411-38020 part number?

Yes. The OEM 13411-38010 and the later supersession/aftermarket designation 13411-38020 refer to the exact same physical crankshaft. Regardless of which number is stamped on your original component, this nodular cast iron replacement will align perfectly with your 22R or 22R-E engine block and bearing shells.
