Toyota 1ZZ-FE Crankshaft Kit with Bearings – MR2 Celica Avensis

Toyota 1ZZ-FE Crankshaft Kit with STD Bearings

This Toyota 1ZZ-FE crankshaft kit contains a new standard-size crankshaft with main bearings, conrod bearings and thrust bearings for compatible Toyota 1.8 VVT-i engines. The crankshaft is an aftermarket replacement for OE reference 13401-22020.

You recieve a new crankshaft with standard-size journals. It is not a reground original. A connecting rod set is available as an optional extra.

What is included?

• 1 × new 1ZZ-FE crankshaft with standard-size journals.
• 1 × STD conrod bearing set made in Japan.
• 1 × STD main bearing set made in Japan.
• 1 × STD thrust bearing set.

Connecting rods are not included in the base kit. Select the optional conrod set when ordering if your rebuild requires replacement rods.

Crankshaft specifications

• Engine: Toyota 1ZZ-FE 1.8 petrol.
• OE reference: 13401-22020.
• Stroke: 91.5 mm.
• Main journal diameter: 48 mm nominal.
• Conrod journal diameter: 44 mm nominal.
• Journal and bearing size: STD.

The journal diameters above are nominal identification dimensions. They are not a substitute for measuring the supplied crankshaft and checking the assembled bearing clearances.

Toyota 1ZZ-FE applications

The following applications are covered by this listing. Dates show the listed production ranges. Confirm the engine code and original crankshaft reference before ordering.

Model names and registration years alone do not confirm fitment. This kit is for the 1ZZ-FE engine. It is not a direct replacement for the 2ZZ-GE crankshaft used in Celica T Sport and other VVTL-i models.

When does a crankshaft need replacing?

Replacement may be needed when the original crankshaft is cracked or when bearing failure has damaged its journals beyond an acceptable repair. Have an engine machine shop assess the crankshaft and the surrounding components before deciding what can be reused.

Fine cracks can be difficult to see during a visual inspection. A machine shop can select a suitable crack-testing method for the crankshaft material. A confirmed crack is a reason to replace the crankshaft. Polishing or regrinding the journals does not remove that concern.

A used replacement also needs inspection before fitting. This new crankshaft avoids the unknown wear and repair history of a second-hand part. It still needs the normal dimensional and clearance checks during assembly.

Checks before fitting a replacement 1ZZ-FE crankshaft

Investigate the original bearing failure

If the egnine developed bearing knock after running low on oil then establish why the oil level fell. On an engine with excessive oil consumption inspect the piston oil-control rings, piston oil drain holes and cylinder bores while it is apart. Deposits around the rings and drain holes can interfere with oil control.

A new crankshaft will not cure an existing oil-burning problem. Address the cause of the oil loss as well as the damaged bearings and journals.

Measure the bearing clearances

STD means standard size. It doesnt guarantee the correct assembled clearance. Toyota uses selective bearing grades within the standard-size range. The original bearing selection marks relate to the original components and should not be used alone to select bearings for this aftermarket crankshaft.

Measure the new journals and check the assembled main bearing oil clearances, conrod bearing oil clearances and crankshaft end float before final assembly. Follow the Toyota workshop procedure and the bearing manufacturer's guidance. Supplied bearings must be checked against the actual crankshaft and engine housings.

Inspect the conrods and main bearing housings

A spun bearing can damage the housing that supports it. Have the affected conrod big-end housing checked for size and roundness before reusing the rod. Inspect the main bearing housings too if the failure involved the main bearings.

New bearing shells canot correct a distorted housing. These checks help establish whether your rebuild needs the optional connecting rod set or further machine work.

Remove bearing debris from the oil system

Failed bearings can leave metal particles in the engine. Clean and inspect the oil passages, sump, oil pickup and oil pump before assembly. Check other components exposed to the contaminated oil. An oil change alone will not remove debris trapped elsewhere in the lubrication system.

Seal the timing cover correctly

The 1ZZ-FE timing cover includes the water pump area. Correct sealing matters because a leak at an internal joint can allow coolant to enter the engine oil. Use the specified sealant and follow the workshop manual's bead pattern and assembly instructions.

1ZZ-FE component and bearing references

These diagrams show the original component layout and Toyota's factory main bearing selection reference. The factory grade chart does not replace clearance measurements when fitting this aftermarket crankshaft.

The MR2 Roadster Owners Club has a 1ZZ strip and rebuild discussion and a 1ZZ teardown following heavy oil consumption and bearing knock. These owner accounts provide useful rebuild context. Use the correct Toyota workshop manual for measurements and assembly procedures.

Fitting and ordering information

Installation requires an engine builder or suitably qualified mechanic with the equipment to measure journal dimensions and bearing clearances. Follow the correct tightening procedures and check crankshaft rotation during assembly. Any additional rebuild parts must be ordered seperately.
